A Novel Multi-Criteria Assessment Approach for Post-COVID-19 Production Strategies in Vietnam Manufacturing Industry: OPA–Fuzzy EDAS Model

The global manufacturing supply chain has been disrupted by the negative impacts of pandemic. In Southeast Asia, Vietnam’s industry is one most strongly integrated with and regional chains. production strategies in “new normal” are key solution to survival sustainable development manufacturers. This study aims develop a two-stage framework investigate COVID-19 post-COVID-19 for industry. As theoretical contribution, this proposes novel robust integration approach, which combines Ordinal Priority Approach (OPA) Fuzzy Evaluation Based on Distance from Average Solution (Fuzzy EDAS), first time. pandemic were identified weighted OPA method. Then, comprehensively evaluated using EDAS Findings indicate that digitization on-site renewable energy essential recovery Vietnam. These findings validated comparisons results recent multiple criteria decision-making (MCDM) methods. Furthermore, weight sensitivity analysis reveals different suitability short-term long-term impacts. managerial implication, multi-scenario ranking help managers make resource-allocation decisions implementation strategies.
