Support for decision-making in response to forest fires is a complex multi-criteria process. This article provides a comparative assessment of the validity of decisions made using three decision support tools. The analytic hierarchy process, analytical network method, and TOPSIS method were used for the assessment. The uncertainty, volume, and degree of heterogeneity of the data taken into account when making decisions were considered as validity criteria. The conducted studies have proven the possibility of using the intelligent decision support system developed by the authors to respond to forest fire threats, as well as increasing their validity compared to other tools.management decisions. The validity of management decisions is understood as an objective representation of the state of the external environment (uncertainty of data and decisions, the volume of processed data, the dimension of the feature space) from the point of view of the problem being solved by the decision maker. The evaluation of tools allows you to determine the preference of tools in terms of the criteria under consideration.
