In response to the problem of traditional third-party logistics distribution evaluation methods ignoring the interaction and interdependence between evaluation indicators, this study constructs a comprehensive evaluation index system using the analytic network process and selects the most suitable logistics service provider. First, the optimization of third-party logistics distribution for agricultural products and the construction of an evaluation index system are carried out. Then, the analytic network process is used to establish a comprehensive evaluation system that includes multiple levels and evaluation index. The results indicate that the analytic network process has the best performance. When the evaluation process is 100%, the complexity, adaptability to dynamic environments, decision consistency, and usability are 57.3%, 19.2%, 92.6%, and 93.1%, respectively. The example analysis results show that the second service provider can be the preferred target. The above results demonstrate the effectiveness of the proposed method, provide scientific basis for the selection of agricultural product logistics service providers, and provide direction for logistics service providers to improve and optimize their services.
