摘　　要：在一个生产商给多个零售商配送单一易腐品的供应链中,考虑了一体化库存路径决策问题,并且零售商为了减少库存和运输相关成本而采用缺货损失策略。产品使用同质车辆配送,而在运输及销售过程中产品具有不同的腐败速率(两阶段腐败)。通过构建数学模型以最小化包括生产、配送、腐败、库存、缺货成本在内的供应链总成本。针对供应链库存决策,用数学证明得到函数性质以确定零售商缺货时间、订货周期及生产商的生产周期。针对离散的路径决策,采用固定分区策略对零售商进行分组,在每个分组内采用遗传算法求解对应的运输策略。设计求解算法并编制matlab程序求解问题,结合数值算例和灵敏度分析说明了模型的有效性及相关管理启示。An integrated inventory routing problem （IRP） is considered in the case where one manufacturer distributes one single deteriorating item to a set of retailers who use the strategy of lost sale to decrease the inventory and transportation related cost. The item is delivered using homogeneous vehicles. During the transportation and the retail stage, the item will have different deteriorating rate （two-stage deterioration）. A proper mathematical model is established to minimize the joint total cost per unit time of the supply chain, including manufacturer＇s cost, distribution cost,deteriorating cost, retailers stock holding cost and shoratge cost. In terms of the inventory decisions, the properties of the object function are derived to efficiently determine the cycle times for the manufacturer and the retailers, as well as the retailers~ shortage intervals. With respect to the discrete routing decisions, firstly the fixed partitions method is used to group all stores into different regions, then the genetic algorithm is developed to find distribution routes for each region. The solution algorithm is developed and implemented using MATLAB software, also the computational experiments are conducted to illustrate the effectiveness of the proposed model and the managerial insights.
