THE METHOD OF COMPLEX APPLICATION OF A SET OF PRINCIPLES OF OPTIMALITY IN THE SELECTION OF EFFECTIVE SOLUTIONS IN THE PRESENCE OF UNCERTAINTY OF THE EXTERNAL ENVIRONMENT AND MULTICRITERIALITY
The article is devoted to the selection of optimal solutions based on a set of criteria in economic and managerial tasks in the presence of uncertainty of conditions. When analyzing the effectiveness of systems for various purposes in the conditions of uncertainty of the external environment, there is a need for a comprehensive application of several principles of optimality. The authors propose a methodology dedicated to an integrated approach to the selection of effective solutions, taking into account the joint consideration of the problems of multicriteriality and uncertainty. Particular attention is paid to the problem of applying various principles of optimality, which entail different conclusions about the effectiveness of decisions. The peculiarity of the proposed methodology is the solution of the problem of matching the results of the application of several principles of optimality. The use of a multi-criteria approach is proposed as a means of coordination, taking into account the optimization of each indicator according to a set of principles. The methodology also takes into account that in conditions of multi-criteria it is necessary to coordinate optimal solutions not only according to different principles of optimality, but also according to different criteria. The paper considers illustrative examples of the implementation of each stage of the methodology.
