Abstract [en]

Product development requires sharing information of a diverse nature between several actors. Since the new products resulting from this process often require assembly as part of their manufacturing processes, it becomes necessary to promote a functional information representation for the assembly domain. Several authors have proposed different core concepts to represent the information related to assembly. However, the resulting body of knowledge is fragmented and lacks a unified concept and definition of the information this concept should contain to be broadly adopted by the academy and industry. This study aims to identify and characterize the core concepts used to enclose the assembly information (e.g., assembly features, ports, connectors, and others) by conducting a literature review in the domain of discrete manufacturing, considering the period between 1985 and 2022. It was found that the literature is rich in concepts but often diverging: a clear depiction of the assembly information required by the involved stakeholders during the whole product development process remains elusive. This work's contribution addresses this gap by identifying the perspectives from which the assembly information can be studied, and the information required to describe the assembly process fully. The resulting information requirements were used to assess the existing approaches addressing assembly information representation. These findings can be used as a base to establish a comprehensive assembly information representation in the future.

Abstract [en]

Digital product development that combines diverse expertise can strengthen the ability to create products that meet customer demands in a commercially viable way. In the early stages of this process, user requirements are translated into technical specifications that define a feasible product concept. Therefore, concept detailing in these stages is essential for manufacturing, as they impact process selection and resources required to manufacture the product.

Given the high proportion of assembled products, assembly becomes an important manufacturing process to study, especially in terms of deriving and propagating product characteristics relevant to this process throughout product development.

One major research gap is the lack of a unified way to represent and distinguish product characteristics defined during design to facilitate assembly, which later serve as essential information for this process.

Multiple research efforts have addressed this issue by proposing various specialized information models for assembly, yet a suitable way to represent this information integrated with the product model is still missing.

This thesis addresses this issue focusing on handling activities for automated assembly by providing a threefold contribution: identifying a core concept to represent assembly information, proposing a way to incorporate assembly information within the product information model by leveraging an international standard, and gathering industry experts' insights to improve this approach for broad and quick adoption.

The outcome of this thesis facilitates the integration of stakeholder information early in product development while providing a space to capture design intent. It also streamlines the identification and subsequent extraction of product information that is decisive in designing dedicated specialized equipment, such as feeders, grippers, and fixtures. Thus, this thesis enables enhancement of communication between design and manufacturing and simultaneously bridges the product and resource life cycles.

Abstract [sv]

Digital produktutveckling som kombinerar expertkompetenser kan stärka förmågan att skapa produkter som möter kunders krav på ett kommersiellt gångbart sätt. I de tidiga faserna av denna process omsätts användarkrav till tekniska specifikationer som definierar ett genomförbart produktkoncept. Därför är konceptdetaljeringen i dessa faser avgörande för tillverkningen, eftersom de påverkar val av processer och de resurser som krävs för att tillverka produkten.

Givet den höga andelen monterande produkter blir montering en avgörande tillverkningsprocess att studera, särskilt när det gäller att härleda och fördela produktegenskaper relevanta för denna process genom hela produktutvecklingen.

Ett stort forskningsgap är avsaknaden av ett enhetligt sätt att representera och särskilja de produktegenskaper som definierats under konstruktion för att underlätta monteringen och som senare utgör väsentlig information för denna process.

Flera forskningsinsatser har fokuserat på detta problem genom att föreslagit olika specialiserade informationsmodeller för montering, men ett lämpligt sätt att representera denna information integrerat med produktmodellen saknas fortfarande.

Denna avhandling adresserar detta problem genom att fokusera på hantering vid automatiserad montering genom att ge ett tredelat bidrag: identifiera ett huvudkoncept för att representera monteringsinformation, föreslå ett sätt att integrera monteringsinformation inom produktinformationsmodellen genom att utnyttja en internationell standard, och samla insikter från experter i industrin för att förbättra denna metod för ett brett och snabbt införande.

Resultatet av denna avhandling underlättar integrationen av intressenters information tidigt i produktutvecklingen samtidigt som det ger ett utrymme för att fånga konstruktionens avsikt. Det effektiviserar också identifieringen och den efterföljande användningen av produktinformation som är avgörande för konstruktion av specialiserad utrustning, såsom matare, gripare och hållare. På så sätt möjliggör denna avhandling förbättrad kommunikationen mellan konstruktion och tillverkning och skapar samtidigt en brygga mellan produktens och resursernas livscykler.
