An optimal batch size for a JIT manufacturing system

This paper addresses the problem of a manufacturing system that procures raw materials from suppliers in a lot and processes them to convert to ®nished products. It proposes an ordering policy for raw materials to meet the requirements of a production facility. In turn, this facility must deliver ®nished products demanded by outside buyers at ®xed interval points in time. In this paper, ®rst we estimate production batch sizes for a JIT delivery system andthen we incorporate a JIT raw material supply system. A simple algorithm is developedto compute the batch sizes for both manufacturing andraw material purchasing policies. Computational experiences of th
