易腐产品的分配政策，从一个区域中心到n个地点在该地区进行了分析。最优近视规则适用于两类政策：轮换政策，未过期的未使用产品被送回中心；以及保留政策，在这些政策中，不可能回到中心。每一单位的短缺或过期都要收取费用。结果表明，最优近视规则使短缺成本和过期成本在一个时期内均达到最小，在现实环境中易于实现，且与单位成本无关。给出了几种需求分布的解析解。最后，给出了一个在血液管理中的应用实例。
Allocation policies of a perishable product from a regional centre to n locations in the region are analysed. Optimal myopic rules are derived for two general classes of policies: rotation policies, where unused product that is not outdated is returned to the centre; and retention policies, where returns to the centre are not possible. Costs are charged for every unit short or outdated. It is shown that the optimal myopic rule minimizes both shortage and outdate costs for one period, it is simple to implement in a realistic environment and is independent of the unit costs. Analytic solutions are given for several demand distributions. Finally, an example of application in blood management is presented.
