Article deals with matters of quantitative methods of creating the optimal range for a small manufacturing enterprise. The classical approach to the formation of an optimal production program based on mathematical methods for linear programming is viewed through the prism of consumer...

When estimating regional inequality, many economists use inequality indices weighted by the regions' shares in the national population. Although this approach is widespread, its adequacy has not received attention in the regional science literature. This paper proves that such approach is...

This paper by using the system of LEAP (Long range Energy Alternatives Planning System) constructs four different energy scenarios for the Greek transport, energy and industry sectors. By projecting the renewable energy use for the years 2020 and 2030 and the associated resulting carbon dioxide...

In many statistical problems there is the need to analyze the structure of an unknown n-dimensional array given its marginal distributions. The usual method utilized to solve the problem is linear programming, which involves a large amount of computational time when the original array is large....

The paper presents methods of linear and nonlinear mathematical programming and their computational implementation in the General Algebraic Modeling System (GAMS). It also presents economic examples and introduces a number of solution algorithms: simplex, gradient, Newton and penalties.

This article examines the potential to create an energy independent smart network for an island community utilizing ocean and wind energy. The analysis involves the simulation of an extensive electrification of the heat and transport sectors on the island and the use of renewable energy to...

In this paper we will solve some linear programming problems by solving systems of differential equations using game theory. The linear programming problem must be a classical constraints problem or a classical menu problem, i.e. a maximization/minimization problem in the canonical form with all...

In our opinion, the performances at group level must be analyzed differently, depending on the adopted strategy. Thus, we consider that a major problem of the accounting and cost control is their compatibility with the strategy. This is justified by the fact that a certain system, that can be an...

The submitted paper is intended to revolutionize the handling methods of credit sheets and the means of collecting budgetary incomes, on one hand, and to allow operators to verify in real time the happening and recording of an economical phenomenon in the area of credit ordination through the...
