T his paper presents a class of methods, called constraint proposal methods, for generating Pareto-optimal solutions in two-party negotiations. In these methods joint tangents of the decision makers' value functions are searched by adjusting an artificial plane constraint. The problem of generating Pareto-optimal solutions decomposes into ordinary multiple(More)
We develop a constructive approach to multi-party negotiations over continuous issues. The method is intended to be used as a mediator's tool for step-by-step creation of joint gains in order to reach a Pareto-optimal agreement. During the mediation process, the parties are only required to answer relatively simple questions concerning their preferences;(More)
In this paper we describe a framework for multicriteria modeling and support of multi-stakeholder decision processes. We report on its testing in the development of a new water level management policy for a regulated lake-river system in Finland. In the framework the stakeholders are involved in the decision process from the problem structuring stage to the(More)
— Empirical evidence suggests that in practice it is difficult to reach Pareto optimal agreements in negotiations. In this paper, we take a constructive approach to this question in two-party negotiations over continuous issues. A new negotiation procedure is presented that results in Pareto optimal agreements under fairly general assumptions. The procedure(More)
Optimal screening has been studied in economics, game theory, and recently computer science. We study the problem in a nonlinear pricing application, where a monopoly designs a price schedule from which the buyers self-select the quality they wish to consume. We formulate a multidimensional model with buyers' utility functions that need not satisfy the(More)
— An approach toward the automated solution of aircraft trajectory optimization problems is introduced and implemented in an interactive program called visual interactive aircraft trajectory optimization (VIATO). This MS Windows-compatible software produces minimum time trajectories to a fixed or moving target. It is easy to use by nonexperts as no previous(More)
We describe a web-site containing material and tools for learning mathematical models of negotiation analysis and discuss students' experiences of its use. The site is part of our general e-learning decision making site, www.dm.hut.fi. The negotiation analysis section provides an introduction to the theory and gives online practice in negotiation support.(More)
