Se aborda el problema de la extensión de una relación de preferencia difusa, definida sobre un conjunto nitido de alternativas, al conjunto de distribuciones de probabilidad sobre éstas.![]()

This paper deals with continuum systems, where a continuous degree of performance levels between perfect functioning and complete failure is allowed. Here we shall assume that the system can be modeled as a structure function given by a mapping [...]![]()

In a previous paper [2], the authors proved that a property of ‘acyclity’ in fuzzy preference relations was anecessary and sufficientcondition for the existence of unfuzzy nondominated alternatives when such aset of alternatives is finite. In th[...]![]()

Brumfield, G. ; Hilden, Hugh Michael ; Lozano Imízcoz, María Teresa ; Montesinos Amilibia, José María ; Ramírez Losada, E. ; Short, H. ; Tejada Cazorla, Juan Antonio ; Toro, M. | Sociedad Matemática Mexicana | 2008-10It has been shown [H. M. Hilden et al., Invent. Math. 87 (1987), no. 3, 441–456;] that the orbifold group U of the Borromean rings with singular angle 90 degrees is universal, i.e. for every closed orientable 3-manifold M3 there is a finite inde[...]![]()

This paper deals with simultaneous auctions of two commonly ranked objects following the model studied in Menezes and Monteiro (J. Real Estate Finance Econ., 17(3):219-232, 1998). For these problems we introduce a parametric family of auction me[...]![]()

Castro, Javier ; Gómez, Daniel ; Tejada Cazorla, Juan Antonio | Pergamon-Elsevier Science Ltd | 2009-05In this paper we develop a polynomial method based on sampling theory that can be used to estimate the Shapley value (or any semivalue) for cooperative games. Besides analyzing the complexity problem, we examine some desirable statistical proper[...]![]()

Castro, Javier ; Gómez, Daniel ; Tejada Cazorla, Juan Antonio | Pergamon-Elsevier Science Ltd | 2008In this paper we define the weighted serial cost sharing rule for the cost allocation problem.We apply this new rule to the problem of sharing delay costs in a PERT network. This rule belongs to the Core and is the Weighted Shapley Value for a p[...]![]()

An important topic in PERT networks is how to allocate the total expedition (or delay) for situations in which the project is not executed as planned. In order to do that we define a TU project game that satisfies some desirable properties from [...]![]()

We propose and analyze a new type of values for cooperative TU-games, which we call pyramidal values. Assuming that the grand coalition is sequentially formed, and all orderings are equally likely, we define a pyramidal value to be any expected [...]![]()

A standard assumption on the Iterated Prisoner’s Dilemma is that the probability of further interaction is constant. Then, cooperation via reciprocity can be guaranteed if and only if this probability is sufficiently high. In this paper, we anal[...]![]()

In this paper, we define a new rule for the resolution of the slack allocation problem in a PERT network. This problem exists of allocating existing extra time in some paths among the activities belonging to those paths. The allocation rule that[...]![]()

En este trabajo se presentan algunos resultados que resaltan la importancia de Ia transitividad máx-mín dentro de las transitividades máx-* , cuando se pretenden definir relaciones de preferencia difusa.
