摘　　要：【目的】考虑到生鲜品易变质的特点,为了减少产品腐坏,降低生鲜厂商供应过程的各类成本,提出了一个随机需求下多时段、多产品的生鲜品协同生产与配送问题。【方法】引入了逻辑斯蒂方程来表示保质期和变质成本的关系,将产品新鲜度的因素加入到目标函数中,建立生鲜品协同生产与配送过程的模型,并用数值例子进行验证,最后将协同优化与单独优化得到的最小总成本做仿真对比分析。【结果】所建模型可以在满足顾客对生鲜品需求的前提下有效地减少保质期的损耗,降低变质成本,得到整个过程的最低总成本。【结论】考虑生鲜品保质期约束的模型对生鲜厂商的实际供应过程有一定的指导意义,且通过仿真对比分析证明了提出的协同优化效果更好,问题模型越复杂,协同生产与配送优化的效果越明显。[Purposes]Considering the perishability of fresh foods,aproblem is put forward with multi-period,multi-product under stochastic demand for integrated production and distribution planning in order to reduce deterioration and the cost of all kinds of fresh manufacturers supply process.[Methods]It introduces the logistic equation to express the relationship between the shelf life and deterioration cost.Factor of product freshness is added to the objective function.On this basis,the model of the fresh foods collaborative production and distribution process is established and then verified by numerical examples.Finally,the optimized minimum total cost of collaborative optimization and independent optimization by simulation are compared.[Findings]The results show that the model can effectively reduce the loss of shelf life and the deterioration cost,finally reduce the total cost of the whole process.[Conclusions]The model considering the shelf life of fresh foods has a certain guiding significance for the actual supply process of fresh manufacturers.The simulation results show that the proposed collaborative optimization is superior to the independent optimization,and the more complex the problem model,the better the effect of collaborative production and distribution optimization.
