A fuzzy MCDM model of service performance for container ports

To achieve the aim of management control function and monitor the service systems at container ports, it is essential to study the evaluation of service performance. The main purpose of this paper is to develop a fuzzy MCDM algorithm (multiple criteria decision-making model) to evaluate the service performance for container ports. Firstly, some concepts and methods used to develop a fuzzy MCDM algorithm are briefly introduced. Secondly, a step-by-step fuzzy MCDM algorithm based on the concept of α-cut is proposed. Finally, a numerical example with a hierarchy structure of five criteria, thirty-one sub-criteria and three alternatives is illustrated, by using the proposed fuzzy MCDM approach. Furthermore, the numerical example shows that the proposed approach can successfully accomplish the study’s goal.
