Research On Multi-source Order Decision Of TR Company Considering The Risk Of Supply Interruption

In recent years,more and more enterprises apply the concept of lean production to daily production and operation.In order to achieve higher production efficiency and market competitiveness,enterprises must closely cooperate with the order decision-making and the sales link.However,the sales link is determined by the market environment.Therefore,reasonable order decision-making is the key issue for enterprises to improve production level,reduce costs and obtain market competitiveness,and also the top priority of enterprise development.When making an order decision,an enterprise should fully consider the actual situation of itself and its suppliers,and try to reduce the supply interruption caused by factors such as delayed delivery and defective rate.At the same time,when the enterprise is faced with capital constraints,it should comprehensively consider the financing situation,so that the order decision will bring continuous development power to the enterprise.Based on this background,considering the risk of supply interruption,the paper makes the order decision again for TR company,and changes the single supplier order mode to a more flexible multi-source order mode,and comprehensively considers the problem of supply interruption risk through the delayed delivery rate and the defective product rate.This paper first introduces the theory of multi-source order decision and supply interruption risk,then analyzes the manufacturing enterprise TR company,and finds that the existing order decision of the company has many problems mentioned above.In order to improve the production efficiency of TR company and avoid the risk of supply interruption as much as possible,the multi-source order decision is proposed for TR company under the condition of considering the risk of supply interruption,and the order decision under the condition of no capital constraint and with capital constraint is given respectively,and the order decision without considering financing and considering financing is proposed under the condition of capital constraint.Finally,the ordering decision is summarized and the future research is prospected.The research results show that the multi-source order decision considering the risk of supply interruption can reduce the total order cost of TR company,save the cost of idle equipment and overtime pay of technical personnel due to delayed delivery and supply interruption caused by defective products;when TR company is faced with the problem of capital constraints,if TR company aims to maintain the existing cash flow,it should adjust the order cost of Q company.Order decision is optimized by constraints.If TR company needs to make project investment,it shall make order decision based on financing situation.When the initial investment amount is small,it shall make order decision considering supply interruption risk and delayed payment financing.When the initial investment amount is large,it shall make order decision considering supply interruption risk and mixed financing.
