Designing a resilient and survivable supply chain under disruptions: Post COVID 19 perspective

人为或自然灾害对供应链运作有很大的影响。随着全球化的不断深入，供应链网络变得非常复杂，容易受到干扰。鉴于2019冠状病毒病（COVID-19）全球大流行的爆发，所有商业部门都越来越需要重组业务，建立有弹性和可持续的供应链。在多元化的今天，一个行业的供应网络与另一个行业的供应网络存在交叉依赖关系。例如，一家汽车公司的供应商也可能是制造呼吸阀的重要部件的生产商。此外，设计一个有弹性的供应链在确保成本效益和可持续性方面带来了挑战。然而，据我们所知，还没有研究调查过这些问题。鉴于文献中的这一空白，我们建议对covid -19后大规模中断和供应链恢复期间的供应链有效管理进行详细研究。为了执行我们的项目，我们与加拿大最大的杂货店和药房零售商Loblaw公司合作。Loblaws在2019- 2020年的销售额约为503.1亿加元，在全国拥有广泛的企业和特许经营商店网络，是合作建立对复杂供应链和物流更好理解的理想行业合作伙伴。实证和定量建模将针对Loblaws的食品、制药和纺织品供应链中当前的主要商业挑战进行。我们的研究结果将为公司实施具有成本效益和弹性的供应战略提供支持。作为一项长期目标，拟议的研究将侧重于设计一个可持续的供应链，使其能够在大规模流行病期间有效运作，并继续为加拿大人提供基本商品和服务。

Human-made or natural disasters have a large impact on supply chain operations. With a deepening of globalization, the supply chain network has become very complex and vulnerable to disruptions. In light of the outbreak of the global pandemic COVID-19, all business sectors have growing needs to restructure their operations with a resilient and sustainable supply chain. In today's diversified world, the supply network of one industry has a cross dependency on the supply network of a different industry. For example, the supplier of an automotive company may also be a producer of an important component for manufacturing respiratory valves. Moreover, designing a resilient supply chain brings challenges in ensuring cost-effectiveness and sustainability. However, to the best of our knowledge, no study has investigated these issues. With this gap in the literature, we propose a detailed study of effective management of the supply chain during large disruptions and supply chain recovery post-COVID-19. To execute our project, we have partnered with Canada's largest grocery and pharmacy retailer, Loblaw Companies Ltd. With sales value of around 50.31 billion Canadian dollars in 2019-20, and a broad network of corporate and franchised stores across the country, Loblaws is the ideal industry partner to collaborate in building a better understanding of complex supply chains and logistics. Both empirical and quantitative modeling will be conducted addressing current major business challenges in the food, pharma, and textile supply chain of Loblaws. The results of our study will support the implementation of cost-effective and resilient supply strategies for the company. As a long-term goal, the proposed study will focus on designing a sustainable supply chain, which can operate efficiently during large pandemics and continue to serve the Canadian with essential goods and services.
