Research On Auction Mechanism Of Third Party Logstics Supplier Selection Under Risk Aversion

With the continuous improvement of the society’s requirements for logistics,the fourth party logistics came into being.The fourth party logistics provided a complete supply chain solution by integrating all resources,while the third party logistics was responsible for the professional logistics project operation.The effect of the fourth party logistics supply chain solutions for enterprise customers is directly affected by the actual logistics operations of third party logistics.Therefore,choosing 3PL suppliers is a key issue in 4PL management.This thesis focuses on the issue of fourth party logistics integrator selecting third party suppliers through auctions,and the in-depth research is mainly from the following aspects:(1)The English auction mechanism and the first-score sealed auction mechanism were designed,and the existing problems were improved to design a two-stage auction.Firstly,the English auction mechanism was designed,we use the prospect theory to construct a new auction scoring function.Both 4PL integrator and 3PL suppliers use the prospect theory to construct a scoring function.In addition,in order to evaluate the auction results under different risk attitudes,the multi-attribute utility theory is used to construct the utility function of 4PL integrators.In order to enable 3PL suppliers to achieve their maximum utility while meeting the auction requirements,the 3PL supplier’s bidding model was designed.Describes the specific English auction process.Secondly,the first price sealed auction mechanism was designed.Different from the English auction,the 3PL supplier’s auction model and auction process.In addition,a two-stage auction was designed to improve the low efficiency of the English auction mechanism and the low of utility of the auction results of the first-score sealed auction to the 4PL integrator.(2)According to the decision-making attitude of 4PL integrator in the auction,considering the impact of the risk aversion attitude on the auction results,The 4PL integrator’s scoring function is mainly used to reflect its risk appetite,the prospect theory was used to construct a 4PL scoring function for risk aversion and risk neutrality.By comparing the auction results under the two risk attitudes,the influence of the risk attitude on the auction results is obtained.(3)This thesis studies the impact of information disclosure on auction results.the thesis considers the expected value and attribute weight in the 4PL integrator’s scoring function.The degree of disclosure of this information will directly affect the bid of 3PL suppliers and affect its score.Therefore,this thesis studies the incomplete information auction for the incomplete disclosure of delivery date and attribute weight.Different from the complete information auction,the expected value and attribute weight are fully announced.Under the incomplete information auction,the 4PL integrator’s expectation value and attribute weight are reserved for the 3PL supplier in the interval form.By comparing the incomplete information auction with the previous complete information auction,the influence of the degree of information disclosure on the auction result is obtained.
