Purpose

The Covid-19 pandemic has caused disruptions in many businesses. A difficult process has been experienced for businesses caught unprepared for this situation. The purpose of the study, the difficulties experienced in the business have been mapped in terms of crisis management.

Design/methodology/approach

For this purpose, crisis management strategies have been discussed in terms of lean six sigma (LSS) strategies. Afterward, LSS strategies have been weighted with the spherical fuzzy analytical hierarchy process (AHP) method, which has been recently introduced to the literature (Gündogdu and Kahraman, 2020). While weighting has been done with the spherical fuzzy AHP method, three experts in the field of LSS at the master blackbelt level have been studied.

Findings

The Covid-19 process has caused the usual processes of businesses to change. Businesses do not have enough time to adapt their business processes in the Covid-19 process. To eliminate waste and time in the Covid-19 process, the lean methodology was used. At the same time, quality deficiencies have been tried to be eliminated with the six sigma methodology. Therefore, the six sigma methodology and lean techniques should be considered together. With LSS, the adaptation of this process has been wanted to be accelerated. In this context, the criteria in the Covid-19 process were prioritized and losses were reduced in accordance with the LSS methodology. In this study, the most important criterion during the covid-19 pandemic has been determined as “responding to the changing needs of customers” and the least important criterion has been determined as “communication with stakeholders in enterprises.”

Research limitations/implications

This study has been applied the Covid-19 pandemics. So, it has been evaluated related to these specific criteria.

Practical implications

Covid-19 crisis management was examined for the first time within the scope of the LSS methodology. The criteria in the Covid-19 process were determined by six sigma expert master black belts. For the first time, spherical fuzzy AHP, one of the multi-criteria decision methods, has been applied to the Covid-19 process.

Originality/value

This study has been aimed to create a roadmap to apply LSS steps in businesses against a possible second wave of the Covid-19 pandemic. In this context, it is thought that the study will fill the following gaps in the literature: Covid-19 crisis management was examined for the first time within the scope of LSS methodology. The criteria in the Covid-19 process were determined by six sigma expert master black belts. For the first time, spherical fuzzy AHP, one of the multi-criteria decision methods, has been applied to the Covid-19 process.

Covid-19危机管理中关于精益六西格码的综合球形模糊AHP多准则方法

目的

Covid-19 大流行已导致许多企业中断。对于没有准备好应对这种情况的企业来说，经历了一个艰难的过程。研究的目的，业务中遇到的困难已被映射到危机管理方面。

设计/方法/方法

为此，已根据精益六西格玛 (LSS) 策略讨论了危机管理策略。之后，LSS 策略使用球形模糊层次分析法 (AHP) 进行加权，该方法最近已被引入文献（Gündogdu 和 Kahraman，2020 年）。在采用球形模糊AHP方法进行加权的同时，研究了LSS领域的三位大师级黑带专家。

发现

Covid-19 流程已导致企业通常的流程发生变化。企业没有足够的时间在 Covid-19 流程中调整其业务流程。为了消除 Covid-19 流程中的浪费和时间，使用了精益方法。同时，已尝试使用 6 西格玛方法消除质量缺陷。因此，六西格码方法论和精益技术应该一起考虑。有了 LSS，这个过程的适应已经被希望加速。在这种情况下，Covid-19 流程中的标准被优先考虑，并根据 LSS 方法减少了损失。在这项研究中，

研究限制/影响

这项研究已应用于 Covid-19 大流行。因此，已根据这些特定标准对其进行了评估。

实际影响

Covid-19 危机管理首次在 LSS 方法的范围内进行了检查。Covid-19 流程中的标准由 6 位西格玛专家黑带大师确定。作为多准则决策方法之一的球形模糊 AHP 首次应用于 Covid-19 过程。

原创性/价值

这项研究旨在制定路线图，在企业中应用 LSS 步骤，以应对可能出现的第二波 Covid-19 大流行。在这种情况下，认为该研究将填补文献中的以下空白：首次在 LSS 方法的范围内检查了 Covid-19 危机管理。Covid-19 流程中的标准由 6 位西格玛专家黑带大师确定。作为多准则决策方法之一的球形模糊 AHP 首次应用于 Covid-19 过程。
