Retrospective analysis of studies on the establishment of the fire source

Introduction. The establishment of the place of occurrence of a fire is one of the main directions of fire-technical expertise. Despite the fact that since the beginning of the XXI century, the productivity of research works devoted to the topic of establishing a fire source has increased, the modern approach does not provide sufficient accuracy of solving the problem, and the fire source is often localized with an unreasonably large error associated with the accuracy of determining the coordinates of the hearth in the room. The brief overview of the most significant studies in the field of fire detection given in the article is aimed at determining the direction of the development of ideas about this subject area, which will eventually make it possible to optimize the research processes, determine the most rational areas of work, allocate resources and regulate the risks of expert errors in the future. Goals and objectives. The purpose of the analysis is to consider the comprehensive problems of research in the field of fire source. The objectives of the study are to objectively assess the methodological approach to the establishment of a fire source, to identify the shortcomings of its establishment and to form the basis for the development of new approaches to the establishment of a fire source. Methods. A retrospective analysis of studies on the problems of establishing a fire source during fire-technical expertise was carried out. During the analysis, the following tasks were performed: selection and preparation of the necessary data for conducting an analytical review; analysis of information; a reasonable idea of the direction of development of the methodological approach to establishing the fire source, as well as the preparation of conclusions based on the conducted retrospective analysis. Results and their discussion. It is determined at what time it appeared, how it manifested itself and the question of the organization and content of research in the field of fire was changing. Since the beginning of the XXI century, mathematical modeling of the dynamics of fire hazards makes it possible to expand the possibilities of predicting results with a significant variation in the initial data on the location of the fire source, which will increase the effectiveness of the study. Conclusions. The second decade of the XXI century is characterized by the intensive development in Russia of works on the creation of new effective methods for establishing a fire source based on the comparison of the results of the study of mathematical models and actual fire data.
