“…Nagurney [28] developed a supply chain network using mathematical modeling concentrated on labor availability during the COVID-19 pandemic for industries and businesses. In other researches considering COVID-19 circumstances, she and her collaborators also carried out studies on a variety of subjects, including presenting a model for demand competition on medical supplies and designing supply chain networks for perishable food [28] , [29] , [30] , [31] .…”

The global epidemic caused by novel coronavirus continues to be a crisis in the world and a matter of concern. The way the epidemic has wreaked havoc on the international level has become difficult for the healthcare systems to supply adequately personal protection equipment for medical personnel all over the globe. In this paper, considering the COVID-19 outbreak, a multi-objective, multi-product, and multi-period model for the personal protection equipment demands satisfaction aiming to optimize total cost and shortage, simultaneously, is developed. The model is embedded with instances and validated by both modern and classic multi-objective metaheuristic algorithms. Moreover, the Taguchi method is exploited to set the metaheuristic into their best performances by finding their parameters’ optimum level. Furthermore, fifteen test examples are designed to prove the established PPE supply chain model and tuned algorithms’ applicability. Among the test examples, one is related to a real case study in Iran. Finally, metaheuristics are evaluated by a series of related metrics through different statistical analyses. It can be concluded from the obtained results that solution methods are practical and valuable to achieve the efficient shortage level and cost.

“…Nagurney et al. (2021) constructed the first Generalized Nash Equilibrium model with stochastic demands to investigate the competition among healthcare organizations for medical supplies in the pandemic. Ivanov (2020) documented a simulation study on the impacts of the Covid‐19 pandemic on global supply chains.…”

In this paper, we develop a unified variational inequality framework in the context of spatial price network equilibrium problems that handles multiple products with multiple demand and supply markets in multiple countries as well as multiple transportation routes. The model incorporates a plethora of distinct trade measures, which is particularly important in the pandemic, as PPEs and other essential products are in high demand, but short in supply globally. In the model, product flows as well as prices at the supply markets and the demand markets in different countries are variables that allows us to seamlessly introduce various trade measures, including tariffs, quotas, as well as price floors and ceilings. Qualitative properties are analyzed. Numerical examples are provided to illustrate the impacts of the trade measures on equilibrium product path and link flows, and on prices, and demand and supply quantities. Given the relevance of the trade measures in the world today and discussions concerning the impacts, the framework constructed in this paper is especially timely.

“…To the best of our knowledge, we are the first to devise a decentralized general scarce resource supply chain network that incorporates multiple fiscal-monetary instruments. The model developed in this paper differs from several existing models by Masoumi et al (2012), Besik and Nagurney (2017), Yu et al (2018), Nagurney andDutta (2019), andNagurney et al (2020) in that our model is broader in scope with the cross-sector concept to capture the interdependence. The inclusion of the scarcity concept as our generality has yet to appear heretofore in literature.…”

In the era of a growing population, systemic change of the world, and rising risk of crises, humanity has been facing an unprecedented challenge of resource scarcity. Confronting and addressing the issues concerning the scarce resource's conservation, competition, and stimulation by grappling their characters and adopting viable policy instruments calls the decision-makers' attention to a paramount priority. In this paper, we develop the first general decentralized cross-sector supply chain network model that captures the unique features of the scarce resources under fiscal-monetary policies. We formulate the model as a network equilibrium problem with finite-dimensional variational inequality theories. We then characterize the network equilibrium with a set of classic theoretical properties, as well as some novel properties (with λ min ) that are new to the literature of network games application. Lastly, we provide a series of illustrative examples, including a medical glove supply chain, to showcase how our model can be used to investigate the efficacy of the imposed policies in relieving the supply chain distress and stimulating welfare. Our managerial insights encompass the industry profit and social benefit vis-à-vis the resource availability and policy instrument design.
