Abstract

From the discussion in Chap. 5, it is clearly apparent that the transformation of an ABCmod conceptual model into a simulation model corresponding to any of the traditional world views requires the extraction and management of the underlying events within the activities that exist in the conceptual model. This unfortunately undermines the semantic clarity of the activity-based approach upon which the ABCmod framework is based. The development of a new world view that preserves the two fundamental modelling artefacts of the ABCmod framework, namely, entities that are instances of entity structures and activities that are instances of activity constructs, is the topic of this chapter. This development of the Activity-Object world view has its foundation on the underlying concepts of the object-oriented programming paradigm. This new world view retains the integrity of the ABCmod building blocks; in particular, the activity is implemented as a class which implies that activity instances become activity objects during the execution of the simulation model. We outline the concepts upon which the Activity-Object world view is based. These concepts are illustrated in the Java package ABSmod/J, which enhances the Java programming environment to facilitate the implementation of ABCmod conceptual models. Details of ABSmod/J are provided in this chapter together with examples of its application.
