The method of supporting decisions under risk was presented in this paper. Making decision under risk takes place when a result of a given decision is not explicit and depends on the condition of the environment. A decision-making process based on multiobjective optimization has been presented in this paper. Methods of multiobjective optimization do not give one unique solution, but a whole set of them. A decision making relies on interactive conducting of the decision making process. Selection of given decision is made by way of solving a problem with parameters defining aspirations of a decision maker and the evaluation of obtained results. A decision maker defines a parameter, for which a solution is indicated. Then he or she evaluates the received solution by either accepting or rejecting it. In the second case a decision maker provides a new parameter value and a problem is solved again for the new parameter.39-50

The paper presents a method of supporting the decision selection in the process of bilateral negotiations. The negotiation process is modeled as using a multi-criteria optimization. The method of finding solutions is the interactive selection process of some proposals. The parties shall submit their proposals to the subjects of the negotiations. These proposals are parameters of the multi-criteria optimization tasks. Selection of solutions is accomplished by solving the optimization task with parameters that define the aspirations of each party involved in the negotiations. Finally, evaluation of the solutions obtained by the parties is done.
