    A pattern and dependency based approach to the design of process models2004In: CONCEPTUAL MODELING: ER 2004, PROCEEDINGS, BERLIN: SPRINGER , 2004, Vol. 3288, p. 724-739Conference paper (Refereed)
    Abstract [en]

    In this paper an approach for building process models for e-commerce is proposed. It is based on the assumption that the process modeling task can be methodologically supported by a designers assistant. Such a foundation provides justifications, expressible in business terms, for design decisions made in process modeling, thereby facilitating communication between systems designers and business users. Two techniques are utilized in the designers assistant, namely process patterns and action dependencies. A process pattern is a generic template for a set of interrelated activities between two agents, while an action dependency expresses a sequential relationship between two activities.

    Modelling institutional, communicative and physical domains in agent oriented information systems2004In: Lect Notes Artif Intell, 2004, p. 189-205Conference paper (Refereed)
    Abstract [en]

    One role of a business system is to provide a representation of a Universe of Discourse, which reflects its structure and behaviour. An equally important function of the system is to support communication within an organisation, by structuring and co-ordinating the actions performed by the organisation's agents. These two roles of a business system may be represented in terms of business and process models, i.e. separating the declarative aspects from the procedural control flow aspects of the system. Although this separation of concerns has many advantages, the differences in representation techniques and focus of the two model types constitute a problem in itself. Abstracting business semantics out of, for instance, technical messaging protocols poses severe problems for business analysts. The main contribution of this paper is a unified framework based on agent oriented concepts for facilitating analysis and integration of business models and process models in a systematic way. The approach suggested bridges the gap between the declarative and social/ economic aspects of a business model and the procedural and communicative aspects of a process model in a technology independent manner. We illustrate how our approach can simplify business and process models integration, process specification, process pattern interpretation and process choreography.
