An analytical theory of multi-echelon production/distribution systems

摘要: In this paper, we study inventory control problems arising in multi-echelon production/distribution chains. these chains, material is delivered by outside suppliers, proceeds through a number of manufacturing stages, and distributed finally among local warehouses order to meet market demand. Each stage requires fixed leadtime; furthermore, assume stochastic, stationary end-item demand process. The problem balance levels service degrees can be modelled analyzed defining appropriate cost functions. Under an average criterion, the three most important structures systems: assembly systems, serial systems distribution systems. For all it possible prove exact decomposition results which reduce complex multi-dimensional simple one-dimensional problems. addition, establish optimality base-stock policies.
