摘要
企业需根据产能确定原材料的供货量、每周的订购量及其间损耗的转运量,可利用TOPSIS优略解距离法计算指标权重综合得分,排序确定最重要的供应商。建立整数规划模型并用程序模拟迭代求解,制定未来24周每周最经济的原材料订购方案与损耗最少的转运方案。建立多目标规划模型,制定尽量多地采购A类和尽量少地采购C类原材料来减少转运与仓储成本及转运损耗率的订购方案及转运方案。计算24周平均每立方米原材料所需单位成本,可知订购方案较为经济,所得结果合理有效。将数学规划模型应用于企业制定订购转运方案中,可对各类订购问题提供指导。
Enterprises need to determine the supply quantity of raw materials,the weekly order quantity and the transfer volume of the loss between them according to the production capacity.TOPSIS optimal solution distance method can be used to calculate the comprehensive score of the index weight and sort the most important suppliers.The study establishes integer programming model,simulate the iterative solution with the program,and develops the most economical raw material ordering plan and the transfer plan with the least loss every week in the next 24 weeks;establishes a multi-objective planning model,and formulates an ordering scheme and a transfer scheme to purchase Class A and Class C raw materials as much as possible to reduce the transfer and storage costs and the transfer loss rate.Then the study calculates the required 24 weeks average unit cost per cubic meter of raw materials.It is found that the ordering scheme is more economical,and the result is reasonable and effective.The application of mathematical planning model to order transfer scheme can provide guidance to various ordering problems.
