The role of simulation in operational planning and control of flexible machining cells

The use of simulation as a solution to the operational planning and control problems of flexible machining cells is now well established. This paper describes the role of simulation models as: a decision support tool, a scheduler and as an aid to develop appropriate control procedures. To illustrate the ideas presented a novel framework for the simultaneous management and control of parts, fixtures and cutting tools is outlined which is termed multi-flow control. Three simulation models have been designed and implemented to carry out specific tasks within this framework. These models and their respective functionality are also described in this paper
