Research On The Project Logistics Operation Based On The Fourth-party Logistics

The demand of the security and timeliness become more and more high. The 4PL has the capability to provide the logistics solution of supply chain, to increase the efficiency and reduce the cost of logistics operation. So, It has the important theoretical and practical value to use the 4PL theory to research the operational problems of project logistics system.The paper based on analyzing the feature, the elements and the system of project logistics, proposed the new method of construction materials classification and established the relationship conceptual model in the member company of the project logistics. Based on analyzing the advantage and the disadvantage of the project logistics operation model at present, proposed the new model of construction material supply logistics based on the 4PL essence and basic theory. Through parsed the motivation of the 4PL services generated in project, constructed the operation system model of the 4PL service in project and the operation achieve in project logistics.The paper based on analyzing the 3PL service providers and the selection method in existence, by constructing the 3PL service providers selection process based on RFP selection method, identified the index system of the 3PL service providers selection in the project logistics, established the model of the evaluation and selection of the 3PL service providers in the project logistics based on the AHP-GRAP, and analyzed its feasibility through an example. By analyzing the transaction cost of before and after structuring the project logistics supply chain and before and after the 4PL service provider enter in the project logistics supply chain, the paper established the coordination mechanism model of the 4PL service provider based on the transaction cost, and analyzed the profitability of project logistics supply chain deeply under the 4PL operation. Based on analyzing the model of the interest distribution in 4PL operation, through the one-time Game analysis of the interest distribution in the member companies, we can design the profit distribution between the 4PL service provider and the member companies reasonable, It will make the effort level and earnings of the Nash equilibrium close to or reach the Pareto equilibrium in the member companies of project logistics supply chain.
