Simulation imposes itself in the field of support and decision making for the analysis, design and exploitation of manufacturing systems. The main properties expected in the simulation took are reusability, abstraction and hierarchy. However, the actual simulation approaches don't offer all these features especially the reusability, except those which are based on the object model. In this paper we present an object oriented approach allowing the modelling and the simulation of manufacturing systems. This approach uses a particular object model and a new analysis approach.
AN OBJECT MODELLING APPROACHIn this perspective, an object-oriented modelling and simulation approach for manufacturing systems is proposed. This approach satisfies some criteria of effectiveness. It is based on three fundamental aspects [Bakalem et a1 941:The consideration of the manufacturing system-on the basis of hierarchical structure composed of five recursive levels (elementary resource, work-station, cell, work-centre and workshop). According to this consideration, a shop is an interconnected network of work-centres, where a workcentre is a set of cells, etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
