ABSTRACT
This study introduces a framework for optimum Common Frequency Routing (CFR) of a JIT system with time-varying demand and flexible production capacities. The system consists of components, people and machines that make useful products. The system is managed across boundaries and interfaces. The boundaries define the scope of the system or subsystem, while the interfaces control the flows through transactions. There are three flows in the JIT manufacturing system model: the flow of materials, the flow of information, and the flow of cost. These flows establish the value streams. Components of the value stream can be value-add or waste, depending on the operating conditions. In this research work, re-design of manufacturing systems into practical optimum Just-In-Time systems will be achieved by integration of computer simulation and analysis of variance. The conventional JIT approach is mostly applicable to static production systems and the dynamic production systems require a more practical integrated JIT approach. However, the re-design of existing dynamic systems into just-in-time systems must follow a practical path, which can be a cumbersome task. This means, a unique practical optimum Just-In-Time system that considers system’s limitations and its dynamic behavior must be designed.
