In this paper, we develop a global supply chain network model in which both physical and electronic transactions are allowed and in which supply-side risk as well as demand-side risk are included in the formulation. The model consists of three tiers of decision-makers: the manufacturers, the...

The COVID-19 pandemic is a major healthcare disaster that has fundamentally transformed our daily lives and the operations of governments, businesses, healthcare operations, and educational institutions. It has elevated and expanded the role of essential workers, not only in healthcare but also...

In this paper, we develop a multitiered competitive supply chain network game theory model, which includes the supplier tier. The firms are differentiated by brands and can produce their own components, as reflected by their capacities, and/or obtain components from one or more suppliers, who...

Fresh produce supply chains have special characteristics, notably, that the quality of the product (fruit or vegetable) deteriorates continuously over time, even under ideal conditions. In this paper, we begin with explicit formulae for fresh produce quality deterioration based on chemistry and...

In this paper, we present a multi-tiered competitive supply chain network model for the blood banking industry, with a focus on the United States, that captures the economic interactions between three tiers of stakeholders; namely, the blood service organizations, the hospitals or medical...

Part I Quality and Supply Chains -- Introduction -- Methodological Foundations -- Part II Information Asymmetry in Quality -- Information Asymmetry and Minimum Quality Standards in Supply Chain Oligopolies -- Information Asymmetry in Perfectly Competitive Spatial Price Equilibrium Problems --...

In this paper, we develop static and dynamic models of global supply chains as networks with three tiers of decision-makers: manufacturers, retailers, and consumers associated with the demand markets, who compete within a tier but cooperate between tiers. The decision-makers may be based in the...

Labor is an essential resource in the functionality of supply chains. The COVID19 pandemic has demonstrated the varied impacts of disruptions to supply chains because of labor issues. Shortages of labor continue even now as economies begin to open up with progress on vaccinations. Investing in...

The COVID-19 pandemic has disrupted supply chains globally with a major shortfall being that of labor shortages from production through distribution activities. In this paper, we construct a new supply chain network optimization model that includes both domestic labor and international migrant...
