    Continuous precise workload control method2014In: IEEE International Conference on Industrial Engineering and Engineering Management, 2014, p. 511-515Conference paper (Refereed)
    Abstract [en]

    The diversity of requirements and the frequency of change in the market can only be competed with dynamicity and responsiveness in both production and planning systems. In this sense, working principles of a novel workload control method, called continuous precise workload control are presented in this paper. The implementation of the method is based on a multi-agent based architecture. The presented approach generates dynamic non periodic release decisions exploiting real time shop floor information. The performance of the system and correlation of norm value against the assessment range are investigated through an experimented test case.

    Characterization of continuous precise workload control and analysis of idleness penalty2016In: COMPUTERS & INDUSTRIAL ENGINEERING, ISSN 0360-8352, Vol. 102, p. 351-358Article in journal (Refereed)
    Abstract [en]

    The variability in the market conditions is growing in terms of its frequency of change and range of diversity. In response to this new industrial panorama, research on production systems is aiming to achieve highly reconfigurable shop floors. Frequent changes in such systems require also frequent re-planning with updated information. In this regard the Continuous Precise Workload Control method, is a recent approach aiming at precise control of workload in shop floor with the use of direct load graphs. Supported by a multi-agent platform, it generates dynamic non-periodic release decisions exploiting real time shop floor information, The study in this paper is two folded; (1) the presented workload approach is defined in terms of eight dimensions of the workload control concept in order to highlight its distinctive characteristics and (2) the impact of idleness penalty factor is analyzed by an experiment design in order to investigate its effect on the job release decision. The results show that the idleness penalty factor decreases the idleness of the resources up to a point where the adverse effect is initiated.

The results show that the idleness penalty factor decreases the idleness of the resources up to a point where the adverse effect is initiated. Besides there are strong indications towards the correlation of idleness penalty factor with the norm value.

    Demand responsive planning: workload control implementation2013In: Assembly Automation, ISSN 0144-5154, E-ISSN 1758-4078, Vol. 33, no 3, p. 247-259Article in journal (Refereed)
    Abstract [en]

    Purpose – Evolvable production systems enable fully reconfiguration capabilities on the shop floor through process-oriented modularity and multiagent-based distributed control. To be able to benefit architectural and operational characteristics of evolvable systems, there is a need of a newplanning approach which links shop floor characteristics and planning operations. This paper seeks to address these issues.

    Design/methodology/approach – Evolvable production system has a structured methodology in itself. Consistent to this, a reference planningarchitecture is developed aiming to achieve agility on planning activities. Besides a workload control method is proposed and implemented as a part ofthe planning architecture.

    Findings – First applications of evolvable systems have been implemented through European research projects. Shop floor working principles andarchitectural characteristics are consistent to facilitate more agility on planning activities which are framed at a planning reference architecture calleddemand responsive planning. As an implementation case, an agent-based workload control method is proposed and implemented. The characteristicsof EPS and proposed planning architecture enable continuous and dynamic workload control of the shop floor to be implemented.

    Originality/value – This paper presents a new planning model compatible with evolvable production systems targeting to agility to demand onplanning and control activities benefiting shop floor enhancements of a fully reconfigurable system which enables to relax constraints imposed fromproduction systems to planning. In addition, a continuous and dynamic workload control method is proposed and implemented.

    Evolvable Assembly Systems: Mechatronic Architecture Implications and Future Research2010Conference paper (Refereed)
    Abstract [en]

    The balance between assembly process optimality and their system’s ability to adapt to new requirements is a key to success for assembly companies. To increase SME’s survivability, an effective methodology is needed to handle the requirements of both agility and mass customization. Evolvable Assembly Systems (EAS) paradigm is a next generation assembly systems focused on these issues. Three key issues are here in focus: process-oriented approach, fine modular granularity, and module intelligence through lighter multi-agent technology at the shop floor level. These issues

    Evolvable production systems and impacts on production planning2011Conference paper (Other academic)
    Abstract [en]

    Production planning and control strategies have been changing in line with the constant change on product and customer requirements, under the light of technological and scientific advancements. Production systems which are based on mass production became obsolete in time hence companies, being profit oriented, are in need of new solutions towards mass customization to handle rapidly changing market conditions. To deal with this issue, production systems and production planning strategies have to be complementing each other. In this paper Evolvable Production Systems and its compatibility to Just in Time (JIT) Production compared to Material Requirement Planning (MRP) will be discussed.

    Abstract [en]

    Europe, as most other OECD areas, is confronted with major potential opportunities in the decades to come. Although often portrayed as threats, the symptoms being denoted in the European economy are, in fact, part of a shift in knowledge and technology infrastructures created by these trends. These current challenges being faced by manufacturing companies nowadays require production systems to become ever more responsive and agile. This is particularly relevant to micro-products, since manual assembly becomes impossible, rendering outsourcing strategies less effective if not deliberately negative. Furthermore, traditional approaches to R&D in this field no longer suffice to cope with the challenges imposed since these imply new business methods, continuous technological evolution, and the increased tendency towards networks of enterprises. To meet such demands there is a need for new rapidly deployable and affordable (economically sustainable) microassembly systems based on reconfigurable, modular concepts that would allow continuous system evolution and seamless reconfiguration. Furthermore, as will be detailed later, one of the requiredfoundations to sustainable assembly system concepts lies within a new way of thinking and working: a methodology that could integrate the various aspects related to the life cycle of the production systems, with particular focus being placed on the re-engineering phase. This article will present some definitions, clarify the basic approach, and outline the serious requirements being posed by such a paradigm: Evolvable Assembly Systems.

    Diagnosis on evolvable production systems2007In: 2007 IEEE International Symposium on Industrial Electronics, Proceedings, IEEE , 2007, p. 3221-3226Conference paper (Refereed)
    Abstract [en]

    Evolvable Production Systems (EPS) lies at the leading edge of the new paradigms currently emerging as a response to the continuously changing socio-economic challenges that modern enterprises have to deal with. Maximizing the profit under adverse market conditions is also a matter of cost cut and EPS targets this through an efficient diagnosis mechanism embedded in future production systems. Evolvable production systems goes beyond other manufacturing paradigms, and offers intelligent devices with biologically inspired behaviours, heavily dependent on self-diagnosis, self healing and other autonomous actions to ensure the systems' proper functioning and a timely response and recover from unpredictable situations.

    Evolvable Assembly Systems: A Development Roadmap2006In: Information Control Problems in Manufacturing 2006, Elsevier, 2006, p. 167-172Chapter in book (Other academic)
    Abstract [en]

    A new paradigm, the Evolvable Assembly Systems (EAS), was recently proposed. This paradigm provides a complete new view on how assembly systems should be designed and developed. Because the control system is one of the key aspects for a successful implementation of EAS this chapter proposes a development roadmap to pinpoint directions of research on how control systems should be developed. It is expected that with this information the industry can envision the potential benefits in terms of competitiveness of this approach. The chapter focuses on the issues that highlight the importance self-organization, dynamical systems, complexity theory, collaborative networks theory, swarm intelligence, and Distributed Artificial Intelligence (DAI) have in the future of EAS. The chapter emphasizes the importance of these mechanisms in solving the increasing challenges imposed upon automatic precision assembly companies that constantly battle to attain agile or evolvable assembly systems.

    The work presented in this paper intends to clarify how multiagents can be an adequate paradigm to solve the challenges imposed by Evolvable Assembly Systems (EAS). The article will therefore show that a multiagent architecture based on coalitions of assembly modules (CoBASA) can be successfully used to implement the control architecture for EAS.

    Abstract [en]

    This paper details the recent development within evolvable assembly systems, including ontological, methodological, and application developments. This paradigm was recently proposed as an answer to the requirements faced by assembly companies in the current world of business and technological changes. EAS, as with other similar approaches, offers great opportunities for attaining true agility and cost- effective, stepwise automation. EAS does imply that the manner in which we develop and create projects for the development of assembly systems are radically changed, assuming a more synthesis-based approach.

In particular, topics on self-organisation, emergence, dynamical systems, and distributed artificial intelligence can be the backbone of truly self-adapting assembly systems. In fact EAS seems to be a really demanding and grounded case-study for the referred research communities.

    Evolutionary Theories in Manufacturing: Inspiration from Biology, Society, and Evolutionary Computing2010In: 10th IFAC Workshop on Intelligent Manufacturing Systems, IMS'10, 2010, p. 210-215Conference paper (Refereed)
    Abstract [en]

    Darwin's evolutionary theory of natural selection has had a strong impact on both science and culture, and has over the last decades become a popular inspiration in engineering sciences. Both the wide range of scientific areas where evolutionary theory is applied, and the simplistic metaphors used to explain evolution in schools and non-scientific situations have caused confusion of how key evolutionary concepts should be understood. In this paper, the cornerstones in biological and social evolutionary theory are identified and addressed from an engineering point of view. Previous efforts to apply evolutionary theories within engineering are then addressed and related to the needs and opportunities within manufacturing and assembly.

    Human-machine Collaboration in Virtual Reality for Adaptive Production Engineering2017In: Procedia Manufacturing, ISSN 2351-9789, Vol. 11, p. 1279-1287Article in journal (Refereed)
    Abstract [en]

    This paper outlines the main steps towards an open and adaptive simulation method for human-robot collaboration (HRC) in production engineering supported by virtual reality (VR). The work is based on the latest software developments in the gaming industry, in addition to the already commercially available hardware that is robust and reliable. This allows to overcome VR limitations of the industrial software provided by manufacturing machine producers and it is based on an open-source community programming approach and also leads to significant advantages such as interfacing with the latest developed hardware for realistic user experience in immersive VR, as well as the possibility to share adaptive algorithms. A practical implementation in Unity is provided as a functional prototype for feasibility tests. However, at the time of this paper, no controlled human-subject studies on the implementation have been noted, in fact, this is solely provided to show preliminary proof of concept. Future work will formally address the questions that are raised in this first run.

    Challenges and properties for bio-inspiration in manufacturing2014In: Technological Innovation for Collective Awareness Systems / [ed] L. Camarinha-Matos, 2014, p. 139-148Conference paper (Refereed)
    Abstract [en]

    The increasing market fluctuations and customized products demand have dramatically changed the focus of industry towards organizational sustainability and supply chain agility. Such critical changes inevitably have a direct impact on the shop-floor operational requirements. In this sense, a number of innovative production paradigms emerged, providing the necessary theoretical background to such systems. Due to similarities between innovative modular production floors and natural complex systems, modern paradigms theoretically rely on bio-inspired concepts to attain the characteristics of biological systems. Nevertheless, during the implementation phase, bio-inspired principles tend to be left behind in favor of more traditional approaches, resulting in simple distributed systems with considerable limitations regarding scalability, reconfigurable ability and distributed problem resolution.

    This paper analyzes and presents a brief critical review on how bio-inspired concepts are currently being explored in the manufacturing environment, in an attempt to formulate a number of challenges and properties that need to be considered in order to implement manufacturing systems that closely follow the biological principles and consequently present overall characteristics of complex natural systems.

    BIOSOARM: a bio-inspired self-organising architecture for manufacturing cyber-physical shopfloors2016In: Journal of Intelligent Manufacturing, ISSN 0956-5515, E-ISSN 1572-8145, p. 1-24Article in journal (Refereed)
    Abstract [en]

    Biological collective systems have been an important source of inspiration for the design of production systems, due to their intrinsic characteristics. In this sense, several high level engineering design principles have been distilled and proposed on a wide number of reference system architectures for production systems. However, the application of bio-inspired concepts is often lost due to design and implementation choices or are simply used as heuristic approaches that solve specific hard optimization problems. This paper proposes a bio-inspired reference architecture for production systems, focused on highly dynamic environments, denominated BIO-inspired Self-Organising Architecture for Manufacturing (BIOSOARM). BIOSOARM aims to strictly adhere to bio-inspired principles. For this purpose, both shopfloor components and product parts are individualized and extended into the virtual environment as fully decoupled autonomous entities, where they interact and cooperate towards the emergence of a self-organising behaviour that leads to the emergence of the necessary production flows. BIOSOARM therefore introduces a fundamentally novel approach to production that decouples the system’s operation from eventual changes, uncertainty or even critical failures, while simultaneously ensures the performance levels and simplifies the deployment and reconfiguration procedures. BIOSOARM was tested into both flow-line and “job shop”-like scenarios to prove its applicability, robustness and performance, both under normal and highly dynamic conditions.

    Characterization of an Agile Bio-inspired Shop-Floor2014In: 2014 12TH IEEE INTERNATIONAL CONFERENCE ON INDUSTRIAL INFORMATICS (INDIN), 2014, p. 404-410Conference paper (Refereed)
    Abstract [en]

    Sustainability is currently one of the biggest challenges and drivers of manufacturing industry. With traditional automation approaches becoming evermore inadequate to support sustainable mass customized production, the research focus is moving towards agile systems that enact companies with the ability to quickly reconfigure their shop-floors by seamlessly deploying or removing modules. Such systems are envisioned as key for attaining a profitable and sustainable industrial development. In this sense, this paper attempts to characterize an innovative approach that relies on bio-inspired concepts as the main control mechanism, in order to foster sustainability by attaining the necessary shop-floor agility. Furthermore an experimental setup is presented and the results are analysed, in order to understand the influence and impact of the main properties of the approach towards the system performance.

    Bio-inspired self-organised mechatronic-agent interactions to support product emergence2013In: IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, IEEE , 2013, p. 7434-7439Conference paper (Refereed)
    Abstract [en]

    The emergence of modern manufacturing paradigms together with the growing interest on distributed architectures has been increasing the use of biologically inspired solutions. However, somehow along the way, developed approaches have converged towards more traditional systems where the physical and logical decoupled nature of the system has been partially lost. In this context, the presented work aims to introduce and analyse a new fully physically and logically decoupled bio-inspired self-organising approach that tries to bring to the mechatronic-agent based manufacturing architectures the dynamics of biological systems. Furthermore, the manufacturing systems are approached from a bottom-up perspective in an attempt to reduce the specification of the production processes to the minimum.

    Abstract [en]

    With the emergence of new modern manufacturing paradigms new concepts, originally from the complexity sciences started to be introduced in the manufacturing systems, rendering traditional control approaches insufficient. Therefore, new approaches were developed, supported by the modern manufacturing paradigms bio-inspired background. However, somehow along the way the physical and logical nature of the system was partially lost, leading to the convergence of approaches towards more traditional systems, 'neglecting' their bio-inspired principles. With the present work the authors aim to introduce and analyse two new different self-organising approaches that try to bring the focus of manufacturing systems, again to the bio-inspired principles. For this purpose, in the context of this work, manufacturing systems are approached from a bottom-up perspective, in an attempt to reduce the specification of the production processes to the minimum and foster the production emergence. A test case is considered, to draw initial conclusions.

    Visualization tool to support multi-agent mechatronic based systems2012In: IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, IEEE , 2012, p. 4372-4377Conference paper (Refereed)
    Abstract [en]

    There has been an increasing interest from industry in distributed architectures since they promote a plug-and-produce and robust environment, where adaptability and fault tolerance are native. Much research has been conducted in this field mainly supported by multi-agent and service oriented technologies. Nevertheless the retrieval and visualization of information in distributed systems is a relatively unexplored area. Although the dynamic nature of the multi-agent systems allows gathering information in a prompt manner, doing so might affect the performance of the mechatronic agents. In this sense, the present paper details the architecture of a visualization tool that introduces a reliable but non-invasive approach to retrieve data from distributed platforms as well as a new way to visualize and interpret the information gathered from mechatronic based systems.

    Evolvable production systems context and implications2007In: 2007 IEEE International Symposium on Industrial Electronics, Proceedings, IEEE , 2007, p. 3233-3238Conference paper (Refereed)
    Abstract [en]

    Agility, reactivity and sustainability are key to cope with today's dynamic markets, as has been broadly recognized. Depending on the source, manufacturing systems are required to be modular, hierarchical or heterarchical, distributed, flexible or reconfigurable; companies can be represented using the Bionic, Fractal and Holonic concepts. Evolvable Production Systems fulfill the majority of the requirements elaborated by the Agile and Reconfigurable approaches and take nature as a metaphor. Modularity of fine granularity and local intelligence allow truly process-specific system design. EPS provide mechanisms for fast reconfiguration at mechanical as well as control level. They apply the Multi-Agent paradigm, which is intrinsically suited for Distributed systems. Inspired by Biology, Artificial Intelligence and Complexity Theory, EPS open the doors for the production systems of the future: the aim is to implement advanced concepts such as Self-Organization, Self-Diagnose and Self-Healing. Coping with emergent behavior will be fundamental, and taking profit of emergent capabilities will open considerable potential for new solutions.

    Standardised flexible automatic assembly - evaluating the Mark IV approach2000In: Assembly Automation, ISSN 0144-5154, E-ISSN 1758-4078, Vol. 20, no 3, p. 217-224Article in journal (Refereed)
    Abstract [en]

    The Assembly Systems Unit at the Royal Institute of Technology and IVF Stockholm has developed several Flexible Automatic Assembly (FAA) cell solutions over the years (Mark I. Mark II, Mark IIF and Mark III). The industrial reality, however, clearly points out that the basic notions of flexibility must be extended and be enhanced without increasing the complexity. This has led our research team to revise the ideas and solutions available for manual and automatic assembly, resulting in the Hyper Flexible Automatic Assembly (HFAA) project. The paper describes the driving factors behind the needs and objectives for the HFAA project, as well as how it will present a standardised set of assembly process-oriented system components. The paper also describes the new Mark IV application. This industrial HFAA system is being developed in order to test the concept's industrial viability. The HFAA concept will allow the user to start from a manual assembly station and gradually add assembly equipment. The basic concepts of stepwise automation, standard assembly machine and sub-batch principle emanate from our previous research.

    Assembly Features Utilization to Support Production System Adaptation2014In: TECHNOLOGICAL INNOVATION FOR COLLECTIVE AWARENESS SYSTEMS, 2014, p. 85-92Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to introduce a proposed methodology to extend the evolvable assembly system (EAS) paradigm for product design by utilizing assembly features in a product. In this paper, assembly features are used to bridge the gap between product design and assembly process by matching features of a part in an assembly to operations of a process in the EAS ontology. This can be achieved by defining and extracting a new set of assembly features called process features, which are features significant to specific and well-defined assembly operations. The extracted assembly features are represented in a proposed model based on product topology. A case-study example is conducted to illustrate the new methodology. A process-feature ontology is proposed as well in order to match the assembly requirements represented by process features with the available processes and skills in the EAS ontology so that adaptation of the production system can be achieved.

    Assembly design semantic recognition using solid works-API2016In: International Journal of Mechanical Engineering and Robotics Research, ISSN 2278-0149, Vol. 5, no 4, p. 280-287Article in journal (Refereed)
    Abstract [en]

    This paper describes a novel approach to recognize and model assembly semantic knowledge enclosed in product assembly features. The proposed approach is based on two stages: assembly semantic recognition and assembly semantic modelling. In the first stage, the internal boundary representation (B-rep) recognition method is utilized to extract assembly semantic knowledge from assembly CAD models using SolidWorks' API functions. In the second stage, a multi-level semantic assembly model is generated. The proposed assembly semantic model is characterized by separating geometrical semantic data represented by form features (basic geometrical and topological entities such as holes, slots, notches etc.) from assembly features (features significant for assembly processes such as mating, alignment, handling, joining etc.). Another characteristic for of the proposed approach is the ability to generate application-specific features based on the extracted geometrical, dimensional and positional semantic data from the assembly design. The generated application specific features will be used to integrate assembly design knowledge to the required assembly processes and resources in the assembly process planning (APP) in product life-cycle. A case-study example is included for illustration of the proposed approach. The work is part of the research within the Evolvable Production Systems paradigm and aims at linking product features to production equipment modules.

    Ontological Approach to Share Product Design Semantics for an Assembly2016In: IC3K 2016 - Proceedings of the 8th International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management, SciTePress, 2016, p. 104-111Conference paper (Refereed)
    Abstract [en]

    The aim of this paper is to facilitate the transfer of product data semantics from Computer Aided Design (CAD) program to assembly process planning (APP) in product life-cycle. In this paper, an approach to capture, share and transfer assembly design semantic data from SolidWorks (SW) CAD software to assembly device (robot Sony SRX series) is proposed. The proposed approach is based, on its first stage, on defining and extracting assembly design semantics from a CAD model using SolidWorks Application Programmable Interface (SW-API). The second stage of the proposed approach includes sharing and integrating the extracted assembly design semantics with assembly robot device by using three-layer ontology structure. In this layered ontology, different types of ontologies are proposed for each layer: general foundation ontology for the first, domain ontologies for the second and application ontology for the third. Each of these layers aids in defining concepts, relations and properties in assembly design domain and APP domain. Ultimately, the proposed ontology will be used to integrate both domains in product-life cycle.

    Modular Product Verifications Based on Design for Assembly2005In: International Forum on Design for Manufacture and Assembly, 2005Conference paper (Refereed)
    Abstract [en]

    The desire to conquer markets through advanced product design and trendy business strategies are still predominant approaches in industry today. In fact, product development has acquired an ever more central role in the strategic planning of companies, and it has extended its influence to R&D funding levels as well. It is not surprising that many national R&D project frameworks within the EU today are dominated by product development topics, leaving production engineering, robotics, and systems on the sidelines. The reasons may be many but, unfortunately, the link between product development and the production processes they cater for are seldom treated in depth. The issue dealt with in this article relates to how product development is applied in order to attain the required production quality levels a company may desire, as well as how one may counter assembly defects and deviations through quantifiable design approaches.It is recognized that product verifications (tests, inspections, etc.) are necessary, but the application of these tactics often result in lead-time extensions and increased costs. Modular architectures improve this by simplifying the verification of the assembled product at module level. Furthermore, since Design for Assembly (DFA) has shown the possibility to identify defective assemblies, it may be possible to detect potential assembly defects already in the product and module design phase. The intention of this paper is to discuss and describe the link between verifications of modular architectures, defects and design for assembly. The paper is based on literature and case studies; tables and diagrams are included with the intention of increasing understanding of the relation between poor designs, defects and product verifications.

    Emerging Behavior as Driver for the Sustainability of a Modular, "Skills-Centric" Production System2011In: IEEE AFRICON 2011, IEEE , 2011Conference paper (Refereed)
    Abstract [en]

    The current main challenge for the future production system lies in the correct integration of the issues related to sustainability and to agility. The "Evolvable Paradigm" addresses this concern with a new way of engineering the whole production system. The concept of Skill is declined as common denominator between the definitions of manufacturing process and manufacturing equipment. Each production module holds some of the skills that compose the process definition and it is endowed with the necessary intelligence to come together with the other modules in an organized society. This work introduces the approach adopted in the IDEAS project (Instantly Deployable Evolvable Assembly System) to cope with the above mentioned requirement through the presented paradigm. While fully featured and described IDEAS mechatronic architecture allows rapid reconfiguration of the system, the issue of sustainability is targeted by the open definition of the concepts of skill and skills interaction. The result of skill aggregation is hereby called Emergent Behavior and in the proposed model it can be seen as the main driver for the sustainable use of the system.

    Abstract [en]

    Current production paradigms and related biases concerning automation are an obstacle for the technological development and subsequent application of intelligent assembly solutions such as the automation based on the evolvable paradigm. A deeper understanding of the potential behind such technology is a fundamental step towards a proficient industrial embodiment. The concept of Value Proposition can be used as a holistic analytical tool able to support a full characterization of the appeal that such technology has on the assembly automation market. The two dimensional bottom-up approach proposed in this work allows the identification and description of six potential value offerings connected with an Evolvable Assembly system, which in turn pave the way to more efficient business models.

    From Flexibility to Evolvability: ways to achieve Self-Reconfigurability and Full-Autonomy2009In: 9th IFAC Symposium on Robot Control, SYROCO '09, Gifu, Japan, 2009, Vol. 42, p. 74-79Conference paper (Refereed)
    Abstract [en]

    In the field of production engineering the past paradigms have focused on the concept of system flexibility; introducing both automation and computer science at shop floor level. Nevertheless their limits in approaching some fundamental areas, such as modularization and control issues, make them unsuitable for tackling the challenges in the manufacturing scenario of today. In this paper the past approaches with their underlining weaknesses have been reviewed, which leads up to the proposal of a methodology for the creation of a manufacturing system that is based on the Evolvable Paradigm. The salient points of this scheme are: the process oriented approach to modularization, the link between the development of the system and the design of the product. Fundamental requirements in pursuing these issues are to deeply study the processes in order to represent them at the hardware level, and to develop a distributed control system to handle emergent behaviour. The potential economical benefits that come from the Evolvable Paradigm include that automation can be a sustainable approach both large enterprises and for SMEs.

    Abstract [en]

    Current major roadmapping efforts have all clearly underlined that true industrial sustainability will require far higher levels of systems' autonomy and adaptability. In accordance with these recommendations, the Evolvable Production Systems (EPS) has aimed at developing such technological solutions and support mechanisms. Since its inception in 2002 as a next generation of production systems, the concept is being further developed and tested to emerge as a production system paradigm. Characteristically, Evolvable systems have distributed control, and are composed of intelligent modules with embedded control. A concerted effort is being exerted through European research projects in collaboration with manufacturers, technology/equipment suppliers, and universities. After introducing EPS, this paper presents current developments and applications.

    Assembly Feature Data Instance Modeling: Prototype Implementation and Outputs2017In: 2017 INTERNATIONAL CONFERENCE ON MECHANICAL, SYSTEM AND CONTROL ENGINEERING (ICMSC), IEEE , 2017, p. 343-347Conference paper (Refereed)
    Abstract [en]

    This paper introduces the assembly feature data schema instance modeling to pre-examine the schema functionality and output- as the preliminary step for data modeling. In order to link assembly with product design, it is essential to determine which entities of product design are involved at the automated assembly planning and operations. It is possible to assign meaningful attributes (assembly features) to the part model entities in a systematic and structured way. Using object-oriented design, the assembly feature data structure and its relationships are modeled. As a part of the research on product and assembly system data integration within the evolvable production system platform, the instance models for proposed assembly feature data structure provide a deeper understanding and error reduction that might possibly occur at the development of the database. Moreover through instance modeling, the assembly feature data query output format from the database prototype is simulated. An industrial assembly model example with its 3DPart models is chosen to demonstrate the realized assembly feature data set with string data type. The models support the desired simplicity at the database prototype implementation. The output format envisions the interoperability factor between product models and the assembly planning systems.

    Object-oriented design of product assembly feature data requirements in advanced assembly planning2018In: Assembly Automation, ISSN 0144-5154, E-ISSN 1758-4078, Vol. 38, no 1, p. 97-112Article in journal (Refereed)
    Abstract [en]

    Purpose - This paper introduces a schema for the product assembly feature data in an object-oriented and module-based format using Unified Modeling Language (UML). To link production with product design, it is essential to determine at an early stage which entities of product design and development are involved and used at the automated assembly planning and operations. To this end, it is absolutely reasonable to assign meaningful attributes to the parts' design entities (assembly features) in a systematic and structured way. As such, this approach empowers processes such as motion planning and sequence planning in assembly design. Design/methodology/approach - The assembly feature data requirements are studied and definitions are analyzed and redefined. Using object-oriented techniques, the assembly feature data structure and relationships are modeled based on the identified requirements as five UML packages (Part, three-dimensional (3D) models, Mating, Joint and Handling). All geometric and non-geometric design data entities endorsed with assembly design perspective are extracted or assigned from 3D models and realized through the featured entity interface class. The featured entities are then associated (used) with the mating, handling and joints features. The AssemblyFeature interface is realized through mating, handling and joint packages related to the assembly and part classes. Each package contains all relevant classes which further classify the important attributes of the main class. Findings - This paper sets out to provide an explanatory approach using object-oriented techniques to model the schema of assembly features association and artifacts at the product design level, all of which are essential in several subsequent and parallel steps of the assembly planning process, as well as assembly feature entity assignments in design improvement cycle. Practical implications - The practical implication based on the identified advantages can be classified in three main features: module-based design, comprehensive classification, integration. These features help the automation and solution development processes based on the proposed models much easier and systematic. Originality/value - The proposed schema's comprehensiveness and reliability are verified through comparisons with other works and the advantages are discussed in detail.

    Abstract [en]

    This paper proposes an approach to developing a cyber-physical model-driven system that performs robotic distant assembly operations in decentralised manufacturing environment. The system uses an industrial robot to assemble components unknown in advance. The system captures and analyses the components’ silhouettes, and constructs the corresponding 3D models. By the help of the models, the system is able to guide a distant human operator to assemble the real components in the actual robot cell. The results show that the developed system can construct the 3D models and assemble them within a suitable total time, imitating the human behaviour in a similar situation.

    Layout validation and re-configuration in Plug&Produce systems2016In: Assembly Automation, ISSN 0144-5154, E-ISSN 1758-4078, Vol. 36, no 4, p. 412-428Article in journal (Refereed)
    Abstract [en]

    Purpose-This paper aims to provide a method and decision support tool to enhance swift reconfiguration of Plug&Produce (P&P) systems in the presence of continuously changing production orders. Design/methodology/approach-The paper reviews different production scenarios and system design and configuration methods and more particularly specifies the need of decision support tools for P&P systems that integrate configuration and planning activities. This problem is then addressed by proposing a method that helps reduce the solution space of the reconfiguration problem and allows the timely selection of the most promising reconfiguration alternative. Findings-The proposed method was found to be helpful in reducing the reconfiguration alternatives that need to be considered and in selecting the most promising one for different orders. The advantages and limitations of this method are identified, and an illustrative test case of the approach is presented, corroborating the method applicability in the absence of large queues in the system. Originality/value-This paper addresses a less explored domain within the P&P systems research field, which is the system reconfiguration. It proposed a method to support system validation and reconfiguration jointly with an illustrative test case. This represents an original contribution to the P&P research field, and it can have impact in improving agility and decreasing the complexity of reconfiguration activities to cope with constantly changing production orders.

    Context and Implications of Learning in Evolvable Production Systems2011In: IECON 2011: 37TH ANNUAL CONFERENCE ON IEEE INDUSTRIAL ELECTRONICS SOCIETY, New York: IEEE , 2011, p. 2740-2745Conference paper (Refereed)
    Abstract [en]

    More than ever the impact of market turbulence, high product customization and sustainability can be perceived through the increase of dynamics and complexity of manufacturing and business environments. Modular and distributed control structures are nowadays a consensual way, common to the majority of modern paradigms, to deal with unpredictability and volatility of markets. With modern paradigms aiming on adaptability, evolution and reconfiguration as a way to deal with this reality, learning mechanism have become very important to achieve such requirements. This paper presents an exploratory discussion on the topic of agent-based learning applied in a modern production paradigm such as Evolvable Production Systems (EPS).

    Prospection of methods to support design and configuration of self-organizing mechatronic systems2013In: Proceedings - 2013 IEEE International Conference on Systems, Man, and Cybernetics, SMC 2013, IEEE , 2013, p. 3854-3861Conference paper (Refereed)
    Abstract [en]

    There is a substantial difference between traditional industrial systems and systems resultant from emerging production paradigms in terms of both conceptualization and implementation. Backwards compatibility is fundamental in assessing the potential transitional period whereby legacy technology will operate under the conceptual framework of modern approaches. However, before this point can be reached it is necessary to further investigate, assess and quantify the behavior of modern approaches that increasingly rely in self-organization. This article's goal is to give an overview of the behavioral assessment problematic, in the context of self-organizing mechatronic systems, and provide a discussion on opportunities to explore rule-extraction techniques to better understand the influence of design and configuration on the overall system behavior. Although the discussion widely applies to almost all emerging production paradigms the Evolvable Production System paradigm is used as case to bring context and clarity to the discussion.
