executing architecture & the role of simulation modelling
A method of creating and using simulation models at multiple levels of granularity is described. The method is based on the use of separated 'process', 'resource' and 'work' sub-system decompositions to facilitate the handling of complexity and change. The method also incorporates the use of new modelling concepts to unify the three sub-system representations into explicit models of candidate system configurations. This enables the representation of architectural structures at multiple levels of abstraction such that multiple simulation models can be derived from a common parent architecture and used to computer exercise reachable behaviours of alternative architectural system designs used within manufacturing enterprises. A case study application shows how, prior to costly real system re-engineering, improved structural dependencies between a manufacturing system and its host business system have been conceived and virtually tested.
