摘要
根据EOQ和时变需求量把计划期内各时间段分为常态时间段和非常态时间段 ,提出求解时变需求订货批量问题的相关策略·从理论上分析了独立策略、非常态独立策略与几种相关策略的性能 ,得到了相关策略的最优结构·提出了基于相关策略的启发式算法求解计划期初是常态时间段的订货批量问题·该启发式对计划期内有多个常态时间段的EOQ问题比S M有效·
The abnormal time periods and normal time periods are distinguished in the planning horizon in light of the EOQ and the time varying demands in the periods. The performance of EOQ policy,dependent policies and independent policies are discussed and the optimal structure of dependent policies for EOQ problems with time varying demands is proposed. A heuristics combined with dependent policies is presented to solve a type of time varying demands with which the first time period is normal. The theory analysis and some simulation showed that the proposed heuristic is better than S M in the case that there exist multiple normal periods in the planning horizon.
