| Logistics is playing a more and more important role in the proceeding of socialproduction and circulating, which is called by the third profit source. Production logistics,as the main part of enterprise logistics, is an important of part of production proceeding.Production logistics optimization is to reduce logistics cost of production proceeding, toimprove core competitiveness of enterprises and one of enterprises’ concern.In this paper, structural parts manufacturing workshop in north traffic heavy groupis considered as the research object which is optimized from the angle of productionlogistics based on TOC under the background of the main multiple products small lotproduction mode in twenty one century. It aims to improve production efficiency,reduce the production cost and optimize the logistics route so as to adapt to the marketchange fast and flexibly. Three-type product processing volume and transport bulkbottleneck identification method is raised based on TOC. Then the bottleneck process ofproduction line can be determined to be the bottleneck type by using the bottleneckidentification method. Objective function of logistics optimization is raised based on mintime and min cost by the bottleneck of production line in structural parts manufacturingworkshop.Finally, bottleneck optimization strategy is given from the aspect of productionplan optimization, processing and transport lot optimization, and material distributionroute optimization. At the same time, material distribution route is optimized from theangle of micro logistics that is internal logistics of enterprise by ant colony algorithmwhich saves distribution time, reduces the stock and improves production efficiency.This paper aims to provide a reference for other enterprises of the same industry byoptimizing structural parts manufacturing workshop. Meanwhile，in the end of this paper,further research orientation is analyzed and the development prospect is expected. |
