带损失率约束的甘蔗企业生产计划模型与算例研究

Production Planning Model and Case Study for Sugarcane Enterprises with Loss Rate Constraint

摘要: 在现代“智慧农业”种植与生产的时代背景下，针对我国甘蔗企业生产加工中普遍存在的蔗糖损失高消耗问题，研究如何有效地降低损失率：在不考虑环境温度和湿度等因素影响下，建立了带损失率约束的生产计划0-1二次规划模型；在对模型的特点进行了分析的基础时，应用内点算法计算得到最优的生产计划执行方案。计算结果表明，编制甘蔗企业生产计划存在着一个优先原则：损失率越高且剩余时间越短的货车，就越优先安排生产；损失率越低且剩余时间越长的货车，就越往后安排生产。

Abstract: Under the background of modern “intelligent agriculture” planting and production, in view of the problem of high consumption of sugar in the production and processing of sugar cane enterprises in China, to study how to effectively reduce the loss rate: without considering factors such as ambient temperature and humidity, the 0-1 quadratic programming model of production planning with loss rate constraint is established; on the basis of an analysis of the characteristics of the model, the optimal production plan execution is obtained by using interior point algorithm. The results show that there is a principle of priority in the preparation of production plans for sugar cane enterprises: the higher the loss rate and the shorter the remaining time, the higher the priority of production; the lower the loss rate and the longer the remaining time of the truck, the more later the arrangement of production.
