Integrating information and material flow executable models, an SDL-based information flow modelling tool

Abstract

Continuous pressure for competitiveness increase led to the concept of enterprise integration. Within this context a modular approach to enterprise modelling, structuring it into manageable units which cooperate with each other according to identified needs and sharing information on request, is mandatory. The approach presented here encompasses a Modelling Workbench supporting the development of applications for the management and control of manufacturing operations: An integrated modelling and simulation environment providing both material and information flow modelling facilities, as well as the integration of material and information flow executable models. Building on Simple ++ , a simulation tool supporting material flow modelling, a class library allowing the use of SDL (Specification and Description Language) for information flow modelling and simulation was developed. The paper also illustrates the SDL environment concept and its significance in the integrated model, as well as its use for shop f...
