Моделі оптимізації завантаження мережі розподілених ситуаційних центрів

Abstract

The article substantiates the relevance of the creation and formulates a mathematical statement of the problem of technical interoperability maintenance in a network of distributed situational centers based on convergent technological solutions. Technical interoperability is considered in the context of optimizing the distribution of situational management tasks between individual situation centers in a distributed network and minimizing information processing time. For this purpose the model and algorithms of optimization of performance of tasks by participants of process of situational management in a network of the distributed situational centers are offered. The model of technical interoperability optimization is presented in the form of a zero-one integer programming problem with the search for the local extremum of the objective function. The information-analytical process is formed as a request that determines the need for information resources, analytical and expert capabilities and service time in each local situation center. The task of optimizing the load of the network of distributed situational centers is to redistribute the load between network nodes by equalizing the use of organizational, human, technical and information resources for timely and quality decision-making in situational centers that serve participants in situational management at different levels. The problem of minimizing service time in a network of distributed situational centers is dual to the primal problem of load redistribution and is solved using a stochastic quasigradient projection method. Algorithms for solving the formulated problems are developed and a test example of application is given. The potential for further improvement of situational systems of strategic planning management based on capability management for target systems is shown
