The choice of options for heterogeneous security systems

Abstract

The article considers a heterogeneous security system, whose elements are the manpower and resources of the interacting law enforcement agencies. The main functions of this system are the prevention, suppression, and discovery of criminal offences, including crimes against public safety and order. To solve this problem, law enforcement agencies monitor the operational situation in the region, as well as various types of urban facilities. However, in case of emergencies, riots and/or other destabilising factors, the current allocation of manpower and resources may be ineffective. In this case, it is necessary to search for the optimal allocation of available manpower and resources among protected locations, taking into account the current situation in a particular region. In order to do this, we formalised the task, which included the description of the parameters affecting the assessment of the effectiveness of the functioning of a heterogeneous security system. Based on this, a model was obtained for assessing the security of objects depending on the choice of a security option and a model for optimising the choice of options for the functioning of a heterogeneous security system. All the considered options for the functioning of the heter-ogeneous security system suggest that the conditions for the maximum security of all objects to be protected are met. The developed model is a high-dimensional nonlinear Boolean programming problem, which prevented us from using exact methods to find a solution. Therefore, we developed a numerical method for solving the problem, based on the theory of greedy algorithms and taking into account the characteristics of the subject area.
