A selection of maximal elements under non-transitive indifferences
'Elsevier BV', 2010Co-Authors: J. R. C. Alcantud, G. Bosi, Zuanon, Magali ErnestineAbstract:In this work we are concerned with maximality issues under intransitivity of the indifference. Our approach relies on the analysis of ‘‘undominated maximals’’ (cf., Peris & Subiza, 2002). Provided that an agent’s binary relation is acyclic, this is a selection of its maximal elements that can always be done when the set of alternatives is finite. In the case of semiorders, proceeding in this way is the same as using Luce’s selected maximals. We present a sufficient condition for the existence of undominated maximals for interval orders without any Cardinality Restriction. Its application to certain types of continuous semiorders is very intuitive and accommodates the well-known ‘‘sugar example’’ by Luce

A selection of maximal elements under non-transitive indifferences
2009Co-Authors: Alcantud, José Carlos R., Bosi Gianni, Zuanon MagalìAbstract:In this work we are concerned with maximality issues under intransitivity of the indifference. Our approach relies on the analysis of "undominated maximals" (cf., Peris and Subiza, J Math Psychology 2002). Provided that an agent's binary relation is acyclic, this is a selection of its maximal elements that can always be done when the set of alternatives is finite. In the case of semiorders, proceeding in this way is the same as using Luce's selected maximals. We put forward a sufficient condition for the existence of undominated maximals for interval orders without any Cardinality Restriction. Its application to certain type of continuous semiorders is very intuitive and accommodates the well-known "sugar example" by Luce

An extended model for project portfolio selection with project divisibility and interdependency
Journal of Systems Science and Systems Engineering, 2015Co-Authors: Shu-cherng Fang, Xiaoling Guo, Zhibin DengAbstract:In this paper, we develop an extended model for the project portfolio selection problem over a planning horizon with multiple time periods. The model incorporates the factors of project divisibility and interdependency at the same time for real-life applications. The project divisibility is considered as a strategy, not an unfortunate event as in the literature, in choosing the best execution schedule for the projects, and the classical concept of “project interdependencies” among fully executed projects is then extended to the portions of executed projects. Additional constraints of reinvestment consideration, setup cost, Cardinality Restriction, precedence relationship and scheduling are also included in the model. For efficient computations, an equivalent mixed integer linear programming representation of the proposed model is derived. Numerical examples under four scenarios are presented to highlight the characteristics of the proposed model. In particular, the positive effects of project divisibility are shown for the first time.

Extending OWL with Maximal Subroperties: An Approach to Define Qualified Cardinality Restrictions and Reflexive Properties
2009Co-Authors: Stanislav Pokraev, Rogier Brussee, Telematica Instituut, P. O. BoxAbstract:Abstract. This paper proposes a simple, single extension of OWL, namely maximalSubPropertyOf that allows to “localize ” a given property to a fixed domain and range. As an application we show that both qualified Cardinality Restriction and reflexive properties can be defined using this construction in conjunction with existing OWL functionality.
