Decision-making for long memory data in technical-economic design, fractals and decision area bubbles

Václav Beran (2003)

Applications of Mathematics

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

Qingjian Zhou, Jia Jiao, Datian Niu, Deli Yang (2013)

RAIRO - Operations Research - Recherche Opérationnelle

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...

Décomposition temporelle et caractérisation de solutions admissibles pour le problème d'ordonnancement à une machine

M.-L. Levy, P. Lopez, B. Pradin (2010)

RAIRO - Operations Research

We propose a temporal decomposition approach for the one-machine scheduling problem with ready times and due dates. A set of feasible schedules is characterized by means of constraint-based analysis rules. They permit the determination of the feasible locations of each task in a sequence, represented by rank intervals. A decomposition procedure based on comparisons of rank intervals is developed in order to group tasks to be sequenced in the neighbourhood of each other in a feasible solution. Computational...

Decrease of C1,1 property in vector optimization

Dušan Bednařík, Karel Pastor (2009)

RAIRO - Operations Research

In the paper we generalize sufficient and necessary optimality conditions obtained by Ginchev, Guerraggio, Rocca, and by authors with the help of the notion of ℓ-stability for vector functions.

Del poliedro del agente viajero gráfico al de rutas de vehículos con demanda compartida.

Carmen Martínez, Enrique Mota (2000)

Qüestiió

En este trabajo abordamos el estudio del poliedro asociado al Problema de Rutas de Vehículos con Demanda Compartida, problema de distribución que surge cuando hay que repartir mercancías a un conjunto de clientes utilizando una flota fija de vehículos de capacidad limitada. El objetivo es diseñar las rutas de forma que se minimice la distancia total recorrida. Se diferencia de otros problemas más conocidos de rutas con capacidades en que se permite abastecer la demanda de cada cliente utilizando...
