Determining the Reliability of Cooperative Decisions by Sensitivity Analysis of Quantitative Multicriteria Decision Methods

Quantitative multicriteria evaluation methods may be effectively used in decision making by a cooperative group, because its members are seeking the solution of the problem by joint efforts. Solving multicriteria problems with conflicting aims, the cooperative group members behave like experts, making decisions based on their views and opinions [1]. The present paper considers the variation intervals of the criteria values and sensitivity of quantitative multicriteria evaluation methods to the initial data of multicriteria problem. Monte Carlo method is used for generating sets of initial data, and the analysis of sensitivity of multicriteria methods is made using a number of sensitivity analysis methods. The outcome of the analysis will be the development of methodology or an algorithm which could help to increase the reliability of decision making based on the use of quantitative multicriteria decision methods or their sets.
