The SPERT problem was defined, in a game theory framework, as the fair allocation of the slack or float among the activities in a PERT network previous to the execution of the project. Previous approaches tackle with this problem imposing that t[...]texto impreso
The focus of this paper is the assessment of groups of agents or units in a network organization. Given a social network, the relations between agents are modeled by means of a graph, and its functionality will be codified by means of a cooperat[...]texto impreso
Gómez, Daniel ; González-Arangüena, Enrique ; Conrado, Manuel ; Owen, Guillermo ; Pozo Juan, Mónica del ; Tejada Cazorla, Juan Antonio | Elsevier | 2003-08A new family of centrality measures, based on game theoretical concepts, is proposed for social networks. To reflect the interests that motivate the interactions among individuals in a network, a cooperative game in characteristic function form [...]texto impreso
En este artículo se estudia en una primera aproximación el juego del Black-Jack o veintiuno según las reglas vigentes en la actualidad en España. Se trata este juego como un proceso de decisión secuencial acotado en el que se intenta maximizar l[...]texto impreso
This paper compares two ways of providing decision support for the allocation of a fixed financial budget among a set of competing highway investment proposals. The first, which is described only in outline, uses a broadly conventional, hierarch[...]texto impreso
This paper deals with the problem of allocating a fixed budget between a set of competing investment proposals. Based on previous practical experience with problems of this type, an analysis using the fuzzy outranking approach promised to be pot[...]texto impreso
The purpose of the paper is to formulate some properties of Orlovsky’s concept of decision making. This concept is related to the notions of max-min and max *-transitivity. The concept of fuzzy acyclicity is proposed to characterize the existenc[...]texto impreso
This paper deals with fuzzy preferences. Many different alternative definitions of strict and weak fuzzy preferences can be found in the literature. But most of them do not take into account that fuzzy preferences should allow a complete prefere[...]texto impreso
In this paper we comment upon the integrated model for valued preferences introduced by Fodor, Ovchinnikov and Roubens. In particular, while on one hand we revise basic assumptions and point out their intuitive meaning, on the other hand we prop[...]texto impreso
Montero, Javier ; Tejada Cazorla, Juan Antonio ; Yáñez, Javier | Emerald Group Publishing Limited | 1994A general concept of a structure function is proposed by considering a general order topology, where possible degrees of performance for the system and its components are going to be represented. Finite multistate structure functions and continu[...]texto impreso
Brumfiel, G. ; Hilde, H. ; Lozano, M. T. ; Montesinos Amilibia, José María ; Ramirez, E. ; Short, H. ; Tejada Cazorla, Juan Antonio ; Toro, M. | World Scientific PublCo | 2017The main result of this paper is the construction of two Hyperbolic manifolds, M-1 and M-2, with several remarkable properties: (1) Every closed orientable 3-manifold is homeomorphic to the quotient space of the action of a group of order 16 on [...]texto impreso
Castro, Javier ; Gómez, Daniel ; Molina, Elienda ; Tejada Cazorla, Juan Antonio | Pergamon-Elsevier | 2017In this paper, we propose a refinement of the polynomial method based on sampling theory proposed by Castro et al. (2009) to estimate the Shapley value for cooperative games. In addition to analyzing the variance of the previously proposed estim[...]texto impreso
We study the relation between the core of a given controlled committee LP-game and the set of payoff vectors generated by shadow prices and core allocations of those simple games describing the control over the different resources. The central p[...]texto impreso
The aim of this paper is to analyse linear production with committee control situations arising when controllers face the possibility of graduating their options. In order to model these situations, we consider several kinds of fuzzy controls, w[...]texto impreso
This paper deals with the problem of designing and choosing auctioning mechanisms for multiple commonly ranked objects as, for instance, keyword auctions in search engines on Internet. We shall adopt the point of view of the auctioneer who has t[...]
