  摘要：W e study determining prices and production jointly in a multiple period horizon under a general, nonstationary stochastic demand function with a discrete menu of prices. We assume that the available production capacity is limited and that unmet demand is lost. We incorporate discretionary sales, when inventory may be set aside to satisfy future demand even if some present demand is lost. We analyze and compare partial planning or delayed strategies. In delayed strategies, one decision may be ...

  摘要：We develop an approximation scheme for performance evaluation of serial supply systems when each stage operates like a single-server queue, and its planned inventories are managed according to a base-stock policy. We also present a near-exact matrix-geometric procedure for benchmarking our approximation relative to two other methods proposed in the literature. Through numerical tests, we demonstrate that our method is superior, both for performance estimation and for policy parameter optimizat...

  摘要：Market pressure for low prices paired with customer demand for high product variety presents a considerable dilemma for many manufacturers. Industry practice and research to date suggest that approaches based on component commonality can substantially lower the costs of proliferated product lines, but at the cost of reducing product differentiation and revenues. We analyze a stylized model of a manufacturer who designs a product line consisting of two products for sale to two market segments w...
