Shop floor control systems (SFCS) are used to make real-time planning and scheduling decisions to optimize the efficiency of manufacturing shops. These shops exhibit a non-linear, dynamic evolution. While simulation models are often used in the aforementioned decisions, Numerous commercial simulation languages typically support one of two views: a process-oriented view or a resource-oriented view. Process-oriented languages view systems as networks in which the nodes represent tasks, connected to processes. The emphasis in this view is on the flow of entities through the processes; the processes themselves and the resources that perform them are hidden. Resource-oriented languages view systems as a collection of resources that perform operations on parts as they flow through the system. The emphasis is on the resources; the processes they perform are hidden. In this paper, we argue that neither view is sufficient for planning and scheduling decisions. We present a new type of simulator that combines both views.
