Corona virus, tariffs, trade wars and supply chain evolutionary design
Purpose
Using the constructal law of physics this study aims to provide guidance to future scholarship on global supply chain management. Further, through two case studies the authors are developing, the authors report interview findings with two senior VPs from two multi-national corporations being disrupted by COVID-19. This study suggests how this and recent events will impact on the design of future global supply chains.
Design/methodology/approach
The authors apply the constructal law to explain the recent disruptions to the global supply chain orthodoxy. Two interviews are presented from case studies the authors are developing in the USA and UK â one a multi-national automobile parts supplier and the other is a earth-moving equipment manufacture. Specifically, this is an exploratory pathway work trying to make sense of the COVID-19 pandemic and its impact on supply chain scholarship.
Findings
Adopting the approach of Bejan, the authors believe that what is happening today with COVID-19 and other trade disruptions such as Brexit and the USA imposing tariffs is creating new obstacles that will redirect the future flow of supply chains.
Research limitations/implications
It is clear that the COVID-19 response introduced a bullwhip effect in the manufacturing sector on a scale never-before seen. For scholars, the authors would suggest there are four pathway topics going forward. These topics include: the future state of global sourcing, the unique nature of a combined âdemandâ and âsupply shortageâ bullwhip effect, the resurrection of lean and local production systems and the development of risk-recovery contingency strategies to deal with pandemics.
Practical implications
Supply chain managers tend to be iterative and focused on making small and subtle changes to their current system and way of thinking, very often seeking to optimize cost or negotiate better contracts with suppliers. In the current environment, however, such activities have proved to be of little consequence compared to the massive forces of economic disruption of the past three years. Organizations that have more tightly compressed supply chains are enjoying a significant benefit during the COVID-19 crisis and are no longer being held hostage to governments of another country.
Social implications
An implicit assumption in the press is that COVID-19 caught everyone by surprise, and that executives foolishly ignored the risks of outsourcing to China and are now paying the price. However, noted scholars and epidemiologists have been warning of the threats of pandemics since the severe acute respiratory syndrome (SARS) virus. The pundits would further posit that in their pursuit of low-cost production, global corporations made naive assumptions that nothing could disrupt them. Both the firms the authors have interviewed had to close plants to protect their workforce. It was indicated in the cases the authors are developing that it is going to take manufacturers on average one month to recover from 4â6 days of disruption. These companies employ many thousands of people, and direct and ancillary workers are now temporarily laid off and face an uncertain future as/when they will recover back to normal production.
Originality/value
Using the constructal law of physics, the authors seek to provide guidance to future scholarship on global supply chain management. Further, through two case studies, the authors provide the first insight from two senior VPs from two leading multi-national corporations in their respective sectors being disrupted by COVID-19. This study is the first indication to how this and recent disruptive events will impact on the design of future global supply chains. Unlike the generic work, which has recently appeared in HBR and Forbes, it is grounded in real operational insight
A Multi-Objective Optimization for Supply Chain Network Using the Bees Algorithm
A supply chain is a complex network which involves the products, services and information flows between suppliers and customers. A typical supply chain is composed of different levels, hence, there is a need to optimize the supply chain by finding the optimum configuration of the network in order to get a good compromise between the multi-objectives such as cost minimization and lead-time minimization. There are several multi-objective optimization methods which have been applied to find the optimum solutions set based on the Pareto front line. In this study, a swarm-based optimization method, namely, the bees algorithm is proposed in dealing with the multi-objective supply chain model to find the optimum configuration of a given supply chain problem which minimizes the total cost and the total lead-time. The supply chain problem utilized in this study is taken from literature and several experiments have been conducted in order to show the performance of the proposed model; in addition, the results have been compared to those achieved by the ant colony optimization method. The results show that the proposed bees algorithm is able to achieve better Pareto solutions for the supply chain problem
Motivations Behind Sustainable Purchasing
Sustainability issues in purchasing are receiving greater attention. Literature is rapidly growing,
with several research programs being initiated to investigate the topic. This study presents the results of a
research project which aims to reveal and structure the motivating forces leading companies to make efforts
in sustainability purchasing and the means used to attain achievements in some fields of sustainability.
Results presented in the literature are scattered in terms of the fields of sustainability: most of the studies
focus only on green or corporate social responsibility issues and there is a lack of exploratory models.
Sustainability in purchasing is addressed in a comprehensive way including green, social responsibility and
corporate growth issues. After presenting the results of a literature review, theoretical development was
undertaken to create a framework in which it is possible to describe the means of sustainability applied and
the motivating forces behind them. This framework serves as the basis for an empirical investigation among
Hungarian companies. Empirical results confirm the usefulness of the theoretical framework: the number
and the characteristics of sustainability activities were determined by the particular types of motivation â to
avoid negative effects, to achieve compliance with expectations and to attain positive effects
The Role of Virtual Integration, Commitment, and Knowledge-Sharing in Improving International Supplier Responsiveness
Globalization has triggered significant structural strategy shifts of multinational enterprises (MNEs). With increasing global competition, MNEs have disintegrated their value-adding activities with their suppliers or subcontractors around the world (Buckley and Ghauri, 2004; Sturgeon, 2002). As a function of this mega-trend, the issue of how MNEs can effectively coordinate and control their global supply chain relationships with local suppliers becomes a critical task for MNE efficiency and competiveness
The future of resilient supply chains
While supply chain resilience has been touched upon frequently, research remains (with the exception of often repeated anecdotal examples) relatively disparate on what disruptions actually are. This research aims to advance theoretical and managerial understandings around the management of supply chain disruptions. A two-stage research process is used which focuses first on polling academic experts. This stage is followed by the extraction of insights from practitioners in the automotive, electronics and food industries. Our findings coalesce around: (1) the types of disruptions that respondents are most concerned about; (2) the associated strategies suggested to cope with disruptions; and, (3) how resilience can be measured. It is apparent that there are some areas where academics and practitioners agree and others where they agree to a lesser extent. Both sets of actors tend to agree on how resilience can be quantified, with recovery time the preferred indicator. However, there is a discrepancy around how resilience is achieved within the supply chain. Academics emphasise the importance of redundancy while practitioners refer more to flexibility. Also, they disagree around what constitutes âkey disruptionsâ: academics suggested high-profile events, while practitioners are more concerned with day-to-day problems
