Some features of ensuring the readiness of fire trucks in the long-term planning of the activities of units

Introduction. The process of operation of fire trucks is investigated. A graph has been constructed that reflects the possible states of the car depending on age. A mathematical description of the possible states of the car is given and the well-known Bellman equation is adapted to describe the function of minimizing the cost of maintaining fire trucks. An algorithm has been developed that describes the conditions for the stay of fire equipment in the category of operation, which ensures the possibility of its use for its intended purpose. Goals and objectives of the study. The goal is to manage the readiness of fire trucks by defining a strategy for their operation and improving the quality of service and repair. To achieve the goal, the tasks were solved to determine the conditions for the stay of a fire truck in the I or II category of operation, a mathematical description of these conditions and an algorithm for the stay of the vehicle in the required category of operation were given. Research methods. In the course of the study, methods of operations research and the method of dynamic programming were used. Results and its discussion. An algorithm has been developed that allows, in the course of long-term planning, to ensure the serviceability of fire trucks and their readiness for use for their intended purpose. Conclusion. The results of the study can be used as practical recommendations for officials of the logistics authorities in the long-term planning of the operation of fire trucks of fire and rescue units in modern conditions.
