ANALYSIS OF DECISION-MAKING METHODS AND MODELS USING CATEGORIES AND METHODS OF TAKING INPUT INTO INFORMATION

Abstract

The article offers an analysis of decision-making methods and models depending on the stages of the decision-making process, the use of categories and methods of taking into account input information that describes the conditions in which the task is performed and the components of the task itself. The most difficult thing in this process is to make such a decision in the conditions of lack of time, information uncertainty and the presence of contradictions in the relevant field. Therefore, when forming management decisions, it is necessary to use a certain classification that corresponds to the area of decision-making and takes into account the specifics of management. The classification of management decisions is presented, taking into account the basics of decision-making theory, management and the nature of tasks that are solved through the interaction of a decision-maker and a decision-making support system. Methods and models are given for each stage of the formed process, which are used depending on the input information. The difference from the traditional sequence consists in the parallel analysis of information, the choice and created alternatives by the decision-maker and the decision-making support system, before a decision is made. The effectiveness of the implementation consists in reduced decision-making time by the person who makes the decision, as he can make a decision using partial information at intermediate stages, even before developing alternatives. In addition, the decision maker can use methods that are not implemented in the decision support system and are based on personal experience and intuition. The scientific novelty of the obtained results lies in the revealed regularities of the use of methods and models in the decision-making process. The relevance of this study is due to the determination of the prospective direction of research using methods and models that will take into account changes in the conditions of the situation or the situation that has developed.
