The Process Integration Evaluation Method of the Fourth Party Logistics Using Fuzzy Theory

The present study give a process integration evaluation method for supply chain integration of the Fourth Party Logistics (4PL), based on fuzzy theory. First, we study the requirements of 4PL, and then transform the collected logistics requirements into the supply chain process design requirements using quality function deployment (QFD) method. Second, we eliminate the non-value process using benchmarking method and rebuild the supply chain based on fuzzy evaluation theory. Third, the optimal model of 4PL is given using multipurpose optimal theory in order that the whole maximum value of partners within 4PL is achieved under time, quality, cost, and service constraints. Fourth, we proposed the evaluation method of 4PL integration solution based on the fuzzy Analytic Hierarchy Process (AHP) method. In the end, the paper point that 4PL is bound to become the direction for Chinese transport enterprises and 4PL market will be promising in future.
