چکیده
This paper deals with the problem of existence of compromise decisions and conditions for a compromise decision to be weakly Pareto-optimal, i.e., to be a weak Pareto-maximizer, Pareto-maximizer, or strong Pareto-maximizer. The concept of compromise decision is generalized by adopting triangular norms. Further, a concept of fuzzy interval is introduced. Suucient conditions for the existence of a max-t decision and for max-t decision to be a (weak, strong) Pareto-maximizer are derived. Finally, a concept called explicit quasiconcavity is deened, which is suucient for a max-t decision to be a strong Pareto-maximizer.

"Multi-Criteria Optimization for Achieving Strategic Fit in Supply Chain (A Pareto Optimality Based Model)"
Modem competitive scenario necessitates the achievement of strategic fit between competitive and supply chain strategies, for effective and economic response in filling customer's orders, by a manufacturing enterprise. Towards this end, all the decisions (strategic, planning and operational) with regard to supply chain ought to be in conformity with strategic fit zone along cost efficiency and ...
متن کاملSolution of Multi-Objective optimal reactive power dispatch using pareto optimality particle swarm optimization method
For multi-objective optimal reactive power dispatch (MORPD), a new approach is proposed where simultaneous minimization of the active power transmission loss, the bus voltage deviation and the voltage stability index of a power system are achieved. Optimal settings of continuous and discrete control variables (e.g. generator voltages, tap positions of tap changing transformers and the number of...
متن کاملOptimality conditions for Pareto efficiency and proper ideal point in set-valued nonsmooth vector optimization using contingent cone
In this paper, we first present a new important property for Bouligand tangent cone (contingent cone) of a star-shaped set. We then establish optimality conditions for Pareto minima and proper ideal efficiencies in nonsmooth vector optimization problems by means of Bouligand tangent cone of image set, where the objective is generalized cone convex set-valued map, in general real normed spaces.
متن کاملCompromise Solutions in Multicriteria Combinatorial Optimization
In multicriteria optimization, a compromise solution is a feasible solution whose cost vector minimizes the distance to the ideal point w.r.t. a given norm. The coordinates of the ideal point are given by the optimal values for the single optimization problem for each criterion. We show that the concept of compromise solutions fits nicely into the existing notion of Pareto optimality: For a hug...
متن کاملA Theorem for Bayesian Group Decisions
This paper presents a natural extension of Bayesian decision theory from the domain of individual decisions to the domain of group decisions. We assume that each group member accepts the assumptions of subjective expected utility theory with respect to the alternatives from which they must choose, but we do not assume, a priori, that the group as a whole accepts those assumptions. Instead, we i...
