Abstract
A mathematical model and methodology has been developed to determine the optimal amount of means of a fire-prevention system for protecting warehouses in enclosed spaces, on the basis of which it is possible to determine measures to improve this system, taking into account the value of the probability of its failure acceptable for the warehouse. The essence of the developed methodology is to determine the required number of fire protection equipment in accordance with the standards, to determine the probability of failure of fire protection and to determine the optimal number of fire protection equipment to ensure the value of the probability of failure within acceptable limits. The optimization criteria selected direct losses from the fire and the costs of fire and rescue units to extinguish it. The function of the goal of this model is to reduce the probability of failure of the fire system of the object to a value less than or equal to the permissible. The input data when using the mathematical model is the estimated number of fire protection equipment in accordance with the norms and standards. The developed methodology allows predicting the probability of failure of the fire system to implement the fire safety of the objects of protection and its consequences for people and material values, which is very important to ensure the possibility of quick response in case of fire. Also, the result of applying the technique is the optimal amount of firefighting equipment at the facility, providing an acceptable value for the probability of failures. This technique is applied on the example of an existing logistic warehouse on which fire protection systems are mounted. Simulation results show that at the facility it is necessary to increase the number of fire detectors up to 70 pieces, smoke control devices – up to 3 pieces, vertical curtains – up to 4, equip aeration lamps in the amount of 4 pieces, and increase the number of evacuation exits - up to 10
Highlights
One of the main tasks that is associated with fire safety for any objects is the development of effective systems and the introduction of all necessary means for fire protection of these objects
At the present stage, when installing fire protection systems (FPS) at the facility, a problem arises that they do not take into account for the facility, in order to reduce the cost of purchasing fire protection systems, the allowable service area for each device in the system
To determine the probability of failure of the fire protection system of the composition, one can use the concept of the total probability of failure of the fire protection system of the IFPS, which will be equal to the product of the probabilities of failure of each component of the FPS
Summary
One of the main tasks that is associated with fire safety for any objects is the development of effective systems and the introduction of all necessary means for fire protection of these objects. In addition to the above analysis of the current state in the field of fire protection of objects, it can be added that the most important drawback is the lack of a methodology for adopting the optimal amount of funds for a particular object to ensure its fire safety All this allows to argue that it is advisable to conduct a study on the development of a methodology for determining the optimal amount of funds to ensure the failure-free operation of fire protection systems of facilities, including closed storage facilities. It should be taken into account that in the event of failure of elements of fire protection systems due to the human factor, failure of power supply elements, the influence of external factors, etc., timely detection and successful fire extinguishing of objects should be ensured
