A cutting stock problem is one of the main and classical problems in operations research that is modeled as LP problem. Because of its NP-hard nature, finding an optimal solution in reasonable time is extremely difficult and at least non-economical. In this paper, two meta-heuristic algorithms,...

Prompted by a real-life observation in the UK retail market, a two-player Prisoners' Dilemma model of an alliance between two firms is adapted to include the response of a rival firm, resulting in a version of a three-player Prisoners' Dilemma. We use this to analyse the impact on the stability...

Purpose: The increase in social awareness, politics and environmental regulation, the scarcity of raw materials and the desired "green" image, are some of the reasons that lead companies to decide for implement processes of Reverse Logistics (RL). At the time when incorporate new RL processes as...

The article dwells upon the dynamic and stochastic mathematical models of organizational development and changes, as well as to the algorithms for their optimization. The adjustment of the intensity of the changes can be achieved through the efficient integration between the departments in...

La presente investigación contempla la conceptualización y estructuración de un modelo de definición y medición del riesgo en la gestión de las MIPYMEs, denotándose cuatro tipos de riesgo de relevancia: Financiero, Legal y Operativo, áreas que definen la gestión en las...

Abstract The digital field certainly provides a lot of information in the medical field, it is possible, in a computerized way, also to simulate epidemics, and the spread of these. There have been events in the past, in some simulation games, which are currently being studied, as they could...

A one-dimensional mathematical model has been developed for a fully hydrated and isothermal PEM fuel cell. Mass transport in the gas flow channels, electrode backing and catalyst layers is accounted for, along with the adsorption, desorption and electro-oxidation of hydrogen and carbon monoxide....

The formation of common electric power space (CEPS) in Northeast Asia (NEA) is considered; the prospective electric power demand of the NEA countries and potential electricity market niches in the region up to the year 2020 are evaluated; export power projects from Russia to other NEA countries are...

The solution of a problem of mathematical description of heat exchange, gas dynamics and the physicochemical phenomena taking place in blast furnace, and some of its application for the study of processes, and defining reduction of metals from multicomponent iron ores are considered.

A growing literature on the subnational diffusion of armed conflict rests on the proposition that political violence triggers more violence, in the same locality and elsewhere. Yet state efforts to contain such uprisings remain largely unexplored, theoretically and empirically. Drawing on a...
