 The global manufacturing supply chain has been disrupted by the negative impacts of the pandemic. In Southeast Asia, Vietnam’s manufacturing industry is one of the most strongly integrated with global and regional supply chains. The production strategies in the “new normal” are the key solution to the survival and sustainable development of manufacturers. This study aims to develop a two‐stage framework to investigate the impacts of COVID‐19 and the post‐COVID‐19 production strategies for Vietnam’s manufacturing industry. As a theoretical contribution, this study proposes a novel and robust integration approach, which combines the Ordinal Priority Approach (OPA) and Fuzzy Evaluation Based on Distance from Average Solution (Fuzzy EDAS), for the first time. The negative impacts of the pandemic were identified and weighted by the OPA method. Then, production strategies were comprehensively evaluated using the Fuzzy EDAS method. Findings indicate that digitization and on‐site renewable energy are the most essential recovery strategies for manufacturing in Vietnam. These findings are validated by comparisons with the results of recent multiple criteria decision‐making (MCDM) methods. Furthermore, weight sensitivity analysis reveals different suitability of strategies for short‐term and long‐term negative im-pacts. As a managerial implication, the multi‐scenario ranking results help managers to make re-source‐allocation decisions for the implementation of post‐COVID‐19 production strategies. © 2022 by the authors.
