- This paper deals with an event-driven optimal control model for a flow type manufacturing system and a systematic control procedure that we developed under the concept of theory of constraints(TOC).
At first. an equation is suggested to find bottle-necks of manufacturing systems. Then a target production level that improves the existing heuristic solutions is derived. According to a two-phase procedure differentiating a bottle-neck and non-bottle-neck control. a system wide control scheme is derived. Priority dispatching and input sequencing are considered in an optimization model that is activated with event-driven style. In this scheme a control point where the bottle-neck locates can also be changed dynamically. Simulation study intends mainly to prove that the performance of our model is greater than or equal to that of the others, but which works in relatively low work-in-process inventory level.
