【Abstract】 A single period assemble-to-order system which consists of a manufacturer and three suppliers is considered in this paper.The manufacturer produces two different types of correlated end products,using a common set of component parts.The inventory management problem for the system is formulated as a two- stage stochastic nonlinear program problem,the decomposition of total expected profit function and the concavi- ty of sub-expected profit function in one variable are proved in this paper.The newsboy optimality condition of order quantities is obtained,and the second stage problem is solved by the component distribution rule given in this paper.更多还原
