分布式供应链中基于准时制的原油采购计划方法

A JIT Planning Approach for Crude Oil Procurements in Distributed Supply Chain

本文研究了分布式供应链多供应商/多炼油厂的原油采购计划问题,建立了在有限资源约束下的准时制多目标采购优化数学模型,以实现总采购费用和供应链循环时间最小。然后,本文将非线性规划模型转化为线性规划模型,并利用层次分析法(AnalyticHierarchyProcess,AHP)与多目标规划相结合的方法求解模型得到采购计划方案。数值仿真结果表明本文所提出的原油采购方法的有效性和实用性。

This paper addresses the crude oil procurement planning problem in distributed multiple supplier/refinery supply chain,and develops under constraints of limited resourcesAn optimal JIT procurement model to minimize the total costs and cycle timeSubsequently,the non-linear programming model is transformed into a linear programming one,which is further solved by a hybrid of the Analytical Hierarchy Process and the multiple objective programming approachFinally,numerical computations demonstrate that the approach proposed for curde oil procurement planning is efficient and applicable
