Evaluation of agri-product supply chain competitiveness based on extension theory

A growing number of enterprises and organizations use various evaluation methodologies to optimize agri-product supply chain by appraising its competitiveness and determining pros and cons. The majority of commonly used evaluation methods only consider the relationship between value and domain, which leads to inaccurate evaluation results. This study sets up a new evaluation model for agri-product supply chain competitiveness using extension theory to solve this defect and amend the evaluation parameters according to current developments in society and economy. A new evaluation index system for agri-product supply chain is established by considering the new indices needed, such as traceability rate. The study also establishes an accurate evaluation model with extension theory. By analyzing and comparing the results of the instance evaluation models based on extension theory and those of the fuzzy comprehensive methods, we obtained evaluation grades 7 and 6 and a similar level of fluctuation, thereby confirming the validity of the newly established evaluation model based on extension theory.
