Over the years, sustainable supplier selection (SSS) has become increasingly popular among scholars and practitioners as a viable means to actualize supply chain sustainability. Little, however, is known about the impact of the COVID-19 pandemic on sustainable supplier selection particularly in the manufacturing sector. In this paper, we present pandemic response strategies as a significant aspect of the COVID-19 pandemic’s impact and investigate the relative importance of such strategies in SSS implementation. Drawing upon a rich data pool from the Nigerian manufacturing sector, we proposed an integrated multi-criteria decision making (MCDM) methodology to analyse the interrelationships between the COVID-19 pandemic response strategies and Triple-Bottom-Line (TBL) criteria for SSS. Our analysis shows that economic criteria and pandemic response strategies are the highest ranked in terms of relative importance and thereby pinpoints the need for manufacturing firms to emphasize such during SSS implementation in the COVID-19 pandemic. Specifically, quality, cost, use of personal protective equipment and use of information technologies for customer demand prediction are inferred as highly significant in SSS implementation in the COVID-19 pandemic era. Furthermore, the efficiency of the proposed methodology was validated by a comparative analysis with other MCDM methods. Therefore, this study presents implications on the significance of pandemic response strategies in SSS and thereby enriches literature on the COVID-19 pandemic’s impact on supply chains.

多年来，可持续供应商选择（SSS）作为实现供应链可持续发展的可行手段越来越受到学者和实践者的欢迎。然而，人们对 COVID-19 大流行对可持续供应商选择（尤其是制造业）的影响知之甚少。在本文中，我们将流行病应对策略视为 COVID-19 大流行影响的一个重要方面，并调查了此类策略在 SSS 实施中的相对重要性。利用尼日利亚制造业的丰富数据池，我们提出了一种综合多标准决策 (MCDM) 方法来分析 COVID-19 大流行应对策略与 SSS 的三重底线 (TBL) 标准之间的相互关系。我们的分析表明，经济标准和流行病应对策略的相对重要性排名最高，因此明确指出制造企业在 COVID-19 大流行的 SSS 实施过程中需要强调这一点。具体而言，质量、成本、个人防护设备的使用以及用于客户需求预测的信息技术的使用被认为对于 COVID-19 大流行时代 SSS 的实施非常重要。此外，通过与其他 MCDM 方法的比较分析验证了所提出方法的效率。因此，本研究揭示了 SSS 中流行病应对策略的重要性，从而丰富了有关 COVID-19 大流行对供应链影响的文献。
