基于改进蚁群算法的煤炭生产企业供应商选择模型构建研究

he coal-production enterprises are considered to be the push procurement environment after analysis, this paper established a objective function taking price, quality, transportation costs, delivery, early delivery and service level as the criterion, a multi-objective 0-1 planning model taking the total number of supplier as the constraints; used the Mei-lin method to obtain the weight and changed it to the single-objective optimization model; then introduced the improved pheromone update rule and solved the supplier selection model Optimally using the improved ant colony algorithm (IACA). At last, the implementation steps are given to provide a scientific basis for the coal production enterprises’ supplier selection to.
