Research On A Two-round Reverse Auction Mechanism In The Centralized E-procurement

In order to reduce procurement costs and improve operational efficiency,government agencies and large enterprise groups mostly chosen the way of centralized procurement in the procurement of goods.With the rapid development of electronic commerce,the reverse auction is becoming widely recognized a new online centralized procurement in recent years.Online reverse auction means that suppliers bid auction bidding system via the network after buyers release purchase needs,then the purchaser accepts all bids and select the final victory target suppliers based on certain rules.However,it should be noted that in many procurement process of commodities,due to the purchase quantity may be far more than the supply of any vendor,often require multiple vendors to supply can meet the demand of purchasing the purchasing.From the current status of research,the traditional reverse auction theory is still insufficient in solving this centralized E-procurement of commodities.Based on that,this thesis proposes a two-round reverse auction mechanism in the centralized E-procurement,adopting system engineering thought,based on the existing achievements reverse auction theory,and this thesis expand the specific research in view of the single item purchase and multiple items purchase.The main contents are as follows:Firstly,we sum up relevant research works,including the auction theory?the reverse auction theory and the research status of the reverse auction.Through the summary,we discuss the deficiency existing in the reverse auction theory in the centralized E-procurement especially the commodities procurement aspects.Secondly,we propose a two-round reverse auction mechanism in the centralized E-procurement,which basic idea is that purchasers split the general subject into several small for bidding.And by giving the basic process design for this based on the idea of "splitting" of the two-round reverse auction,we analyse theoretically the key factor involved in the auction process.Thirdly,on the basis of the above auction mechanism research,we design a two-round of reverse auction method based on the thought of splitting,considering a single item of centralized E-procurement.We have established the amount split algorithm model,designed the ssolution algorithm of the model,through concretely studying the core problem of designed auction mechanism.And we verify the validity of the proposed model and algorithm by simulation example.Fourthly,considering various objects in the centralized purchasing online furtherly,we designed the two-round of reverse auction based on the "Splitting and Package" thought.We have established the packing model,designed the ssolution algorithm of the model,through concretely studying the core problem of designed auction mechanism.And we verify the validity of the proposed model and algorithm by simulation example.
