A Fuzzy Evaluation Method of Integrated Logistics Service Networks

摘要

This paper presents a simple and effective approach to evaluate the integrated logistics service networks. Considering the three logistics service networks, the fuzzy language variables are introduced to represent the value of the criteria, and the weights of assessing criteria are obtained by the average method of the evaluations by the Experts or the decision makers. Then the likelihood degree of the trapezoidal fuzzy numbers is defined and the fuzzy complementary judgment matrix is given. Thus, the rankings of the logistics service networks under each criterion and the synthetically criteria are both calculated. Finally, a simulation example is given to show the validity and feasibility of the method.
