Models of network reliability in the optimization-s task of structure of system for management of multicoordinate relocation of transmitting modules

Network reliability is a very important concept for all networks, especially industrial and the task of its increasing is one of the main tasks of designing network-s structures. Network reliability is the main criterion of selecting this or that network structure. In this article we propose new method of network reliability-s increasing, which mean involving and using local interfaces for solving specified task. We consider 10 different network structures, calculate its reliability, compare and analyze. After that we introduce the concept of network-s structure cost, calculate costs of all considered network structures and formulate two optimization-s tasks. First task is to find network-s structure, having the most reliability and satisfying to restriction on the value of network cost. Second task is to find network-s structure, having the least cost and satisfying to restriction on the value of network reliability. Also we propose algorithms for solving both of these tasks.
