能力规划、促销与库存控制集成决策

研究了多周期联合能力规划、促销和库存管理集成决策问题．在每周期开始，决策者同时决定生产能力，促销水平和生产量．刻画了最优策略的结构以及能力与促销之间的关系，证明最优能力规划是目标区间策略，即在每一周期，存在一个最优能力区间，对生产能力做最少的调整，使生产能力落到这一区间．一旦生产能力确定，最优促销与库存策略是修正base-stock-target-promotion策略．促销是生产能力和初始库存的增函数．推广了前人的相关结果．

Integrated decisions on capacity flexibility,promotion and inventory control
