OPERATIONS PLANNING BASED ON THEORY OF CONSTRAINTS DECISION SYSTEM

The raw material, the machines, and the execution operations required by production are not the only necessary resources. Information is already more important than the physical resource. The designing and the maintaining of an updated information system represent a more difficult and expensive approach. The Theory of Constraints Decision System (TOCDS) is an experimental system and deals with constraint handling decision in manufacturing operations. It is purposed to define the optimal sequence of the various operations in a flow shop, considering machines and tools available. The decisions are based upon comparative reports between the marginal analyses and a report called the “product contribution”.
