Аnnotation

A “combined” method of practical research has been developed as part of a non-technical survey of a territory likely contaminated with explosive objects, which will reduce the time of such survey and reduce the risk of injury to personnel of pyrotechnic units due to the absence of physical contact of personnel with the likely contaminated territory. A mathematical model of a “combined” method for practical research of a supposedly contaminated territory with explosive objects during non-technical inspection has been developed. The mathematical model was obtained from the results of collecting indirect evidence, where the status of an explosive object is not determined. A control algorithm for implementing the “combined” proposed method has been developed, which takes into account the area of the suspicious dangerous territory, which is examined by one non-technical survey group based on the collection of direct and indirect evidence. In addition, when constructing the algorithm, indicators such as the number of groups, the level and type of their equipment were taken into account. The algorithm consists of 12 blocks located at 7 hierarchical levels and connected by direct and feedback connections. When determining the area to be cleared of explosive objects, the area of the territory that has received confirmation of the status of a dangerous zone and the area of the territory of a confirmed dangerous zone are taken into account when checking indirect evidence of a possibly contaminated territory by excluding this territory from the total area of a possibly contaminated territory. The implementation of the proposed method (due to visualization of the area in a 3-D projection with the determination of the exact geographical coordinates of local and general zones of the dangerous territory) will reduce the time of non-technical inspection by 3.9 times, as well as reduce the time of complete demining and clearing land from explosive objects, increase the level of security for civilians in cleared areas.
