Note. Periodic Review (s, S) Policies for Joint Replenishment Inventory Systems
针对随机需求下的联合补货问题，提出一种新的P(s, S)策略，即对每个物品独立采用周期盘点（s, S）策略。测试结果表明该策略优于其他策略。
This note deals with the joint replenishment problem with stochastic demands. A new class of policies called P(s, S) policy is proposed for this problem. The proposed policy uses independent, periodic review (s, S) policies for each item. Results on test problems show that the proposed policy is superior to other classes of policies for the problem.
