Reverse Auction Procurement Mechanism Design And Choose

In recent years,the environment that enterprises facing is more and more competitive?The importance of purchasing activities in the operation of enterprises has been standing out.With the popularity of e-commerce,supplier market increasingly expanding,procurement model has been innovative,and enterprises are facing the choice of procurement model.There are mainly two procurement:bargaining procurement and reverse auction procurement.In bargaining procurement,buyer usually choose a known supplier for long-term cooperation.In the reverse auction procurement,the buyer launches a public bidding,so the final trading partner is unknown,and the cooperation of suppliers is often for one-time.When there are known long-term partner and unknown new suppliers,the problem of corporate procurement decision-making is to choose to negotiate with the original long-term supplier in one-on-one procurement,or choose to introduce new suppliers to bid for reverse auction.Considering China's national situation,some of the procurement activities must implement the open auction in the form of reverse auction,but at the same time,to maintain long-term cooperation with the old supplier has a certain management significance.In this case,the paper designs the long-term cooperation in the reverse auction procurement mechanism,and studies the selection strategy.First of all,in the comparison between bargaining procurement and reverse auction procurement,the paper establishes the bargaining model under the generalized Nash equilibrium and the first-price sealed reverse auction model,then the equilibrium results are solved.To study the selection strategy,the paper takes the maximization of the buyer's profit as the goal,and takes the bidding number and the long-term supplier negotiation power as the decision variables,then establishes the selection model and analyzes the critical condition of the buyer's choice,finally makes the sensitivity analysis.Next,the paper revised the standard first-price sealed auction mechanism,considering the long-term cooperation in the reverse auction mechanism with distinguishing the long-term suppliers to other bidders.Then resolves the mechanism modeling and results the balanced outcomes.Finally,the paper compares the long-term cooperation reverse auction and the standard reverse auction mechanism in the optimal bid strategy,the expected transaction price,and the expected yield of both buyer and old supplier.In the end,the paper gives selection strategy for buyer and old supplier in two reverse auctions.The paper studies the selection strategy of buyer in the three procurement models:bargaining procurement,reverse auction procurement and reverse auction procurement considering long-term cooperation.In theory,the paper makes up for the shortcoming of the comparative field of bargaining theory and reverse auction theory.In detailed,the paper analyzes which mechanism is more effective by using the bidder and the bargaining force as the decision variables.In addition,a new reverse auction mechanism is designed and the according optimal equilibrium results are obtained.In practice,the paper provides solutions for enterprises to choose the procurement model and inspires that enterprise can not blindly choose the procurement model.Taking into account the project procurement is forced to reverse the auction procurement,the paper gives solution that long-term cooperative relationship can be considered.
