Decision Making in Reverse Logistics Using System Dynamics
Decision-making for long memory data in technical-economic design, fractals and decision area bubbles
Economic and management theories are very often based in their applications on the perception of homogeneity of the application space. The purpose of this article is to query such a conviction and indicate new possible directions of discipline development. The article deals with symbiosis of process and his steering model as a process of management. It is possible that in relative near future it will be necessary to accept approaches and changes in interpretations of decision-making. Applications...
Decision-making of portfolio investment with linear plus double exponential utility function
This paper broadens the exponential utility function commonly used by risk-averse investors to the linear plus double exponential utility function, which is applicable in most cases. Thus it is of essential and supreme significance to conduct a research on its optimal investment portfolio in securities investment. This paper, by means of the non-difference curve method, carries out a research into the optimal portfolio decision-making by investors who have this type of utility function. The optimal...
Distancias elipsoidales y puntos eficientes. Un método interactivo.
En este trabajo se estudian las propiedades que relacionan las distancias elipsoidales con la generación de puntos eficientes de un problema de programación multiobjetivo. Basándonos en estas propiedades, hemos construido un algoritmo interactivo convergente.
Double pondération pour calculer une moyenne : Pourquoi et comment ?
L'opérateur de moyenne pondérée est très souvent utilisé pour définir une valeur v(a) à des entités a à partir de performances xj(a), j=1,...,n. Cet opérateur fait intervenir des poids spécifiqueswj comme multiplicateurs de la performance relative à la je composante. Ceci induit des possibilités de compensation des mauvaises performances par les meilleures qui peuvent être jugées inacceptables dans certains contextes concrets. En vue d'atténuer ces possibilités de compensation, on peut faire intervenir...
