Collaboration quality assessment in the sustainable rice supply chain by using an integrated model of QFD-FANP-DEA: A case study of the rice industry in Malang

Collaboration is one of the critical issues in achieving a sustainable supply chain among suppliers and BULOG, the Indonesian Logistics bureau operated by the government that balances economic, social, and environmental aspects. Factors of collaboration behaviour such as commitment, trust, coordination, stability, and continuous improvement are taken into account to support collaboration activities. This study aims to analyse the efficiency score of BULOG and its suppliers and determine the strategy to enhance collaboration quality. This study applied the integrated method of Quality Function Deployment (QFD), Fuzzy Analytical Network Process (FANP), and Data Envelopment Analysis (DEA). The QFD and FANP are to figure out the priority level of the collaboration behaviour factors. Then, DEA serves to calculate the collaboration efficiency score. The result shows that the most important behaviour factor in supporting the collaboration is the coordination, followed by continuous improvement, commitment, stability, and trust. Furthermore, among the nine stakeholders, two stakeholders are inefficient, with the efficiency score of 88.8% and 87.5%. Several strategies that can be applied to achieve the highest efficiency score (100%) are by increasing the sales level and changing the transportation method. Therefore, the economic and the environmental aspects which have a low level can be improved.
