【摘要】：随着市场经济的发展,企业逐渐把供应链管理作为其提高市场竞争力的主要手段之一,其中对库存食品的温度控制作为食品供应链管理中极其重要的一个环节,引起了广大企业和学者的关注,并使得易逝性食品的质量受到广大消费者的日益关注.食品的易逝性特征彰显了对库存食品温度控制的重要性,能否合理的生产、存储以及运输易逝性食品与企业的利益以及社会经济的发展密切相关. 本文考虑食品质量衰减以及温控成本,建立了使企业总收益达到最大的易逝性食品的动态定价模型.模型中将仓储温度视为连续变量,所考虑的系统的需求以及产品定价均具有时变性特征,同时需求还受产品定价影响.利用Pontryagin最大值原理得到最优解的必要条件,进而得到了产品的最优定价及仓储温度.在考虑一般衰减系数的基础上,建立了产品的温度控制及一次定价模型,利用一维搜索算法计算出产品的最优生命周期,得到了最优仓储温度和产品价格.最后,对模型的管理意义进行分析,并通过算例验证了所提方法的有效性.
[Abstract]:With the development of market economy, enterprises gradually regard supply chain management as one of the main means to improve their market competitiveness, and the temperature control of food inventory is an extremely important part of food supply chain management. It has attracted the attention of enterprises and scholars, and made the quality of perishable food more and more concerned by consumers. The perishable character of food shows the importance of controlling the temperature of food in stock. Whether we can reasonably produce store and transport perishable food is closely related to the interests of enterprises and the development of social economy. Considering food quality attenuation and temperature control cost, a dynamic pricing model of perishable food is established. In the model, the storage temperature is regarded as a continuous variable, the system demand and product pricing are time-varying, and the demand is also affected by the product pricing. The necessary conditions for the optimal solution are obtained by using the Pontryagin maximum principle, and then the optimal pricing and storage temperature of the product are obtained. On the basis of considering the general attenuation coefficient, the temperature control and primary pricing model of the product are established, the optimal life cycle of the product is calculated by one-dimensional search algorithm, and the optimal storage temperature and product price are obtained. Finally, the management significance of the model is analyzed, and the effectiveness of the proposed method is verified by an example.
