摘要 针对乳制品生产商—分销商—零售商构成的三级冷链下日益严重的食品质量问题,进行了三级冷链一体化库存模型研究。首先,引入了质量努力水平参数作为客户满意度的衡量标准,来刻画生鲜农产品的质量与利润的关系;其次,考虑到需求受产品质量影响且变质率服从三参数Weibull分布,以总利润最大化为目标函数建立三级冷链库存模型,同时对冷链上各成员的库存量及生产量用自适应遗传算法进行了规划求解;最后,以冷链中的乳制品库存—生产问题为案例进行仿真,验证了模型的有效性,并对质量努力水平进行灵敏度分析。结果表明,冷链各级成员考虑产品质量时,冷链整体利润更大,且质量努力水平越大,总利润越高。

英文摘要 In view of the increasingly serious food quality problems, this paper carried out a three-level cold chain integrated inventory model research. First, this paper built an inventory model for the integrated three-echelon cold chain, and it determined the inventory and production of each member of the cold chain from the perspective of maximizing total profit in the supply chain. Secondly, this paper considered that demand was affected by product quality, and the metamorphic rate obeyed the three-parameter Weibull distribution. Therefore, it established a three-level cold chain inventory model with the total profit maximization as the objective function, at the same time, it solved the inventory and production volume of each member of the cold chain. Finally, it carried out the simulation on the case of a dairy stock-production problem in a cold chain. The conclusion verifies the validity of the model. This paper also conducted sensitivity analysis on the level of quality effort. The results show that when the supply chain strives for product quality at all levels, the overall profit of the supply chain is greater. Moreover, the greater the level of quality effort, the higher the profit in the supply chain.
