Competition under time‐varying demands and dynamic lot sizing costs

We develop a competitive pricing model which combines the complexity of time‐varying demand and cost functions and that of scale economies arising from dynamic lot sizing costs. Each firm can replenish inventory in each of the T periods into which the planning horizon is partitioned. Fixed as well as variable procurement costs are incurred for each procurement order, along with inventory carrying costs. Each firm adopts, at the beginning of the planning horizon, a (single) price to be employed throughout the horizon. On the basis of each period's system of demand equations, these prices determine a time series of demands for each firm, which needs to service them with an optimal corresponding dynamic lot sizing plan. We establish the existence of a price equilibrium and associated optimal dynamic lotsizing plans, under mild conditions. We also design efficient procedures to compute the equilibrium prices and dynamic lotsizing plans.© 2008 Wiley Periodicals, Inc. Naval Research Logistics 2009     

【邀请论文】美军未来司令部探析——成立背景、主要职能与未来前景

新一轮科技革命的快速发展正推动战争形态从信息化向智能化演进。美军作为二战后始终位列世界第一的军事力量，正在积极设计未来战争以应对当前的“大国竞争”，2018年刚刚成立的陆军未来司令部正是在这一背景下产生的。未来司令部隶属于美国陆军，主要负责美陆军新型武器装备的研发、未来作战概念创新以及新兴军事科技的测试和应用。成立两年以来，未来司令部已经拥有了一套完善、严密的组织架构，创造了包括C5ISR作战概念在内的一系列理论成果，在空基导弹、远程精确火力系统等新型作战装备上也取得了众多进展。本文基于大量前沿文献研究，廓清了未来司令部的组织架构，总结了其主要职能，并对这一新设司令部的发展前景进行了展望和预测，期望能够为推进军队现代化和未来化建设提供有益启示。

Production planning with resources subject to congestion

A fundamental difficulty in developing effective production planning models has been accurately reflecting the nonlinear dependency between workload and lead times. We develop a mathematical programming model for production planning in multiproduct, single stage systems that captures the nonlinear dependency between workload and lead times. We then use outer linearization of this nonlinear model to obtain a linear programming formulation and extend it to multistage systems. Extensive computational experiments validate the approach and compare its results to conventional models that assume workload‐independent planning lead times. © 2009 Wiley Periodicals, Inc.
