The Optimization Solution Of Purchasing System Of Company S’s In Supply Chain Environment

As the business growing awareness of supply chain management, and also because procurement as an important link in the supply chain, more and more companies have their optimized procurement system to adapt to the competitive market environment. On the one hand, implementation of the procurement system optimization, companies can make right purchasing strategy and reduce procurement cost, when companies are buying from the supply market where is rapidly changing. On the other hand, response mechanism of reaction speed in the supply chain can also make advances; smoothly purchasing process at the same time also will drive the other business operation efficiency in companies. This article selects the domestic well-known cosmetic and daily products manufacturing enterprise company S as the research background. Based on the deferred payment widely used in the industry of Company S, and based on the company’s internal procurement process of supply chain coordinated response mechanism, discussed the whole procurement system of company S for their procurement strategy and process optimization problems.In this paper, we summarize the previous research work, this article established how to give flexible payment deadline based on the one-level delay in payments, and then confirm the deadline data according to the one-level delay in payments to make the maximum profit, meanwhile, this article also analyzed the application model of two-level delay in payments of three-level supply chain of company S, in order to optimize the order volume and period to upstream distributors. Based on the delay in payments term from company S to customers and from distributors to company S, this article conducted the following analysis:1. Based on the background that company S allows its customers to put off payment, considering the relationship between deferred payment period and order volume, this model designed delay in payments strategy to allow the maximum of profit system.2. Based on the background that company S allows its customers to put off payment if getting a loan, suppose in the process of purchasing negotiation, distributors allow company S to put off payment, and the order strategy of company S including optimal order period and the theoretical value of order batch has been confirmed. Using the demand parameter of one product as an example, exerting methods of statistical analysis, mathematics tool Matlab, etc., this article analyzed how to optimize repayment time and the deferred period should be granted to its customer under deferred payment ways.3. Under the circumstance of three-level supply chain, in order to implement the delay in payment purchasing strategy smoothly and to respond to customers’ order in time, this article also continued to analyze and optimize the purchasing flow of company S. In the end, it applied Petri net theory analysis to optimize the flow, time and performance.
