摘要
假定冷链库存费用随时间线性增长;有质损现象发生;市场销售价格先缓慢上升,在某一时刻达到顶点,然后缓慢下降.基于上述假定,构建了以库存商品全部售完后盈利最大为目标、以上市时刻为决策变量的优化储存销售模型,应用非线性规划条件极值法给出了模型解法.通过一个算例进行了仿真,证明了模型的可行性和有效性.
Assuming that the inventory costs in cold chain increase linearly and time-dependently with mass loss and that the selling prices of refrigerated goods rise slowly and come up to the peak at a certain time,then the prices are going down slowly,an optimal model is developed for storage/sales of refrigerated goods,where the objective is maximizing the profits after the stocks have all been sold out with the selling time taken as a decision variable.The conditional extreme value method of nonlinear programming is used to solve the model.Simulation results verified the feasibility and effectiveness of the model by a numerical example.
