Collaborative Management of a Sustainable Supply Chain in a Water Diversion Project

Measuring the level of collaboration in the sustainable supply chain (SSC) of water diversion projects is of great value to the sustainable operation of the project. To this end, a scientific and reasonable collaboration measurement method must be developed. Given the economic, environmental and social benefits of water diversion projects and based on the theory of the SCC, an order parameter index system for collaboration measurement was constructed in this study. The DEMATEL and analytic network process methods were used to compute the local and global weights of each order parameter. A total of 161 valid questionnaires were collected from residents along the middle route of the South-to-North Water Diversion Project (SNWDP) to measure the collaboration on this project from 2018 to 2020. The results showed that the orderliness of the four flow subsystems of the middle route of the SNWDP increased annually. Compared with the other three flow subsystems, the knowledge flow subsystem showed a lower level of orderliness, suggesting that communication and exchanges among people along the route should be strengthened. These findings can help identify the weak link in the collaborative management of the SSC of water diversion projects and improve collaboration efforts in a targeted manner.
