In facility layout problems, a major concern is the optimal design or remodeling of the facilities of an organization. The decision maker's objective is to arrange the facility in an optimal way, so that the interaction among functions (i.e. machines, inventories, persons) and places (i.e....

In this paper the issue of mathematical programming and optimization has being revisited. The theory of optimization deals with the development of models and methods that determine optimal solutions to mathematical problems defined. Mathematical model must be some function of any solution that...

A version of the classical secretary problem is studied, in which one is interested in selecting one of the b best out of a group of n differently ranked persons who are presented one by one in a random order. It is assumed that b is bigger than or equal to 1 is a preassigned number. It is...

In this paper we study Markov Decision Process (MDP) problems with the restriction that at decision epochs only a finite number of given Markovian decision rules may be applied. The elements of the finite set of allowed decision rules should be mixed to improve the performance. The set of...

Income per capita is an important and hence widely used measure in the construction of social welfare weights. This paper, however, aims to discuss the construction of social welfare weights based not merely on Income per capita but on equally distributed equivalent income (EDEI). For example,...

The speed of the application of current economic policies that are being followed in Turkey is a very important question. This paper uses the results of the solutions of optimal control theoretic inventory and production problems for companies to offer opinions on this question under various...

This study illustrates how the recent developments in efficiency analysis and statistical inference can be applied when evaluating banks’ performance issues from a potential merger. By using a sample of 29 Greek commercial banks the paper provides a six step procedure in order to evaluate...

Narrow passageways are a significant source of traffic congestion and delay in transportation networks. With traffic volumes expected to increase significantly in the foreseeable future, the effective management of these passageways is needed to mitigate the undesirable impact of these...

Any linear programming problem marked as P and called ”primal” can be seen in connection with another linear programming problem marked as D and called ”dual”. The economic interpretation of the dual model brings about new information when analyzing such phenomena and when substantiating...

Este artículo emplea la teoría del portafolio de Harry Markowitz paraconstruir dos portafolios, cada uno compuesto por cinco acciones de laBolsa de Valores de Colombia. Estos portafolios se elaboran pensandoen dos inversionistas con aversión al riesgo, pero con distinto nivelde tolerancia al...
