基于食品安全的生鲜食品冷链运营优化研究

针对我国生鲜食品冷链物流成本高、食品易腐败的特点,在考虑食品安全的基础上,本文利用生鲜食品质量衰减原理,设计了基于温度控制的多产品分阶段生鲜食品冷链运营模式,建立数学模型对冷链配送网络选址、配送路线规划以及各环节温度选择进行优化研究,在保障食品质量安全的同时最大程度降低物流成本,最后通过算例仿真及对比研究验证了模型及算法的可行性和有效性.

The optimization of cold chain operation based on fresh food safety

For the high cost of cold chain and highly perishable for fresh food, we integrate food quality in decision-making of food cold chain storage and distribution management. We provided a methodology to describe the food quality degradation and designed a multi-stages multi products fresh food cold chain operation mode, which can be integrated in a mixed-integer linear programming model to optimization distribution center location, route planning and temperature selection in order to ensure food quality and safety while minimize the logistics cost. Finally the numerical simulation and comparative study was given to verify the feasibility of the model and the algorithm.
