鉴于缺货时产品间存在需求替代性情况,研究存在鲜度惩罚成本的生鲜品生产排程.将降低保质期损耗、失销成本、替代成本和库存水平等目标统一到企业利润最大化中建立目标函数;考虑生产准备、生产切换和生产批量等因素,构建生产约束、排序约束、资源约束和库存约束;在典型并行设备生产排程的基础上构建有保质期约束的生鲜品生产排程的混合整数非线性规划模型.通过某生鲜品企业的生产数据进行验证,运行Gurobi 5.6.3软件进行求解.结果表明,该模型可以有效地制定出企业的生产排程计划,提高企业利润;产品需求替代率对生产排程、成本和收益产生巨大影响.

Considering the situation of demand substitution among the products while out of stock,the production scheduling of fresh food with freshness penalty cost is researched. The reduction of the loss of shelf life,lost-sale cost,substitution penalty cost and the level of inventory are considered to build an ob-jective function in order to maximize the corporate profit. Considering these factors such as production preparation,production switch and production batch,production constraints,ordering constraints,re-sources constraints and inventory constraints are constructed. On the basis of typical parallel equipment production scheduling,a mixed integer nonlinear programming model is built for the production schedu-ling of fresh food with shelf life constraint. The model is verified using the production data of a fresh food factory and is solved by Gurobi 5 . 6 . 3 . The results show that the model can effectively work out enterpri-ses’production scheduling plan and improve profits. The product demand substitution rate has a big im-pact on the production scheduling,costs and benefits.
