Manufacturers provide products that have distinct green levels (ie higher degree of
environmental friendliness) to satisfy consumer demands with different green preferences. A …

Throughout history, networks have provided the foundations by which humans have
conducted their economic activities. Transportation and logistical networks make possible …

In this paper, an equilibrium model of a competitive supply chain network is developed.
Such a model is sufficiently general to handle many decision-makers and their independent …

The variational inequality problem has been utilized to formulate and study a plethora of
competitive equilibrium problems in different disciplines, ranging from oligopolistic market …

In this paper, we developed a new model of oligopolistic competition for fashion supply
chains in the case of differentiated products with the inclusion of environmental concerns …

Since I started working in the area of nonlinear programming and, later on, variational
inequality problems, I have frequently been surprised to find that many algorithms, however …

In this paper, we develop a supply chain network model consisting of manufacturers and
retailers in which the demands associated with the retail outlets are random. We model the …

A model with two firms competing in location and sales is analyzed for the case of spatial
discrimination. Consumers are uniformly distributed along a line segment and have identical …

We consider the framework of aggregative games, in which the cost function of each agent
depends on his own strategy and on the average population strategy. As first contribution …

This paper captures different environmental tax policies in a multi-tiered supply chain
network competition context. We derive the governing equilibrium conditions for the …
