Risk Assessment of Production Resumption Based on Improved Multi-Level Fuzzy Evaluation Method

The struggle of humanity against infectious diseases represents a long-term dynamic equilibrium. In anticipation of the next pandemic, proactive emergency preparedness for foreseeable challenges is imperative. This paper focuses on the research concerning the risk assessment of resuming business operations during the course of an infectious disease pandemic. We apply Best Worst Method (BWM) to improve multi-level fuzzy comprehensive evaluation model. According to the policy and the actual situation of the epidemic, we establish an evaluation system for the production resumption, and take Enterprise A as an example to verify the feasibility of the model. It is found that Enterprise A has poor preparation for production resumption, and is at a high-risk level. It is not recommended to resume work and production when it is not necessary. When it is necessary, enterprises can resume production. They need to pay attention to strict prevention and control, and return to work to participate in daily nucleic acid testing within three days. This research is universal and can be extended to other enterprises to provide reference for the government and enterprises to make prevention and control decisions.
