缺货的模糊需求回收物流库存控制模型及算法

为了研究模糊需求下回收物流的库存问题,对退回物品采用批量修复处理的方式,在不考虑提前期的情况下,假设销售商允许消费者退货,且退货服从Poisson分布,建立了一个包括单位购买成本、维修成本、库存成本和缺货成本的回收物流最优库存策略模型.引入模糊模拟和遗传算法相结合的混合智能算法,对不确定需求的回收物流单周期库存模型求解,以找到模糊情况下总成本的估计,从而推导出与之相对应的最优定购量.最后,应用一个实例对结果进行讨论,表明该算法有一定的有效性.

A Model and Algorithm of Inventory Control with Fuzzy Demand Based on Recovery Logistics

In order to study the recycle logistics inventory problem with the fuzzy demand, this paper applies the batch method for returns recovery.Not considering the lead-time and supposing that the product return is permitted and has the Poisson distribution,this paper establishes an optimal reverse logistics inventory strategy model that includes the ordering cost,the service cost,the stock cost and the shortage cost,and introduces the hybrid intelligent algorithm to solve the single-period recycle logistics inve...
