Research existing scientifically grounded approaches to improving the efficiency of complex technical systems, which fully applies to local computer network, allowed to conclude about the formation in recent years a new priority approach associated with providing the system properties of functional stability. A functional criteria and indicators of local computer network stability are proposed. Implementation of functional stability is achieved by using different types of redundancy (structural, temporal, informational, functional, load, etc.) in a complex technical system. The proposed model for estimation the functional stability of the local computer network uses the principle of decomposition of complex procedures to ensure functional stability into simpler steps and offers a methodology for calculating the probability of a generalized indicator of functional stability as a connectivity matrix structure convolution. This approach allows estimating and comparing the different topologies of local computer network and applying them to form techniques of the optimal use of redundancy systems to prevent the consequences of emergency situations.
