Network reliability (network reliability) measures the performance of the network. Network is a special case of associated systems. Network reliability mainly studies the algorithm of network reliability and the complexity of the algorithm. Due to computer networks, communication networks, etc. Appeared, network reliability has become an active research topic since the 1980s. The methods of network reliability calculation mainly include:

1. Decomposition method. Let the corresponding reliability function of the network be h (p), and use the decomposition formula

h (p) = p; h (l;, p) + q; h (O;, p),

Where p is the reliability of arc i, p; + q; = l, p = (p), pz, ...} pn), <O;, p), <l;, p) The two components are respectively. , A vector of 1. From the above formula, the calculation of h (p) becomes the calculation of h (O;, p), h (l;, p) for n-1 variables.

2. First find all the minimum road sets A Az, ...} Am, and then use the network system is normal -A1} Az} ...} Am at least one minimum road set is normal. So the system reliability

R = P {UA;}

Here, A means that the second minimum path set is normal. In the formula, R is usually obtained by the exclusion formula or disjoint method.

3. Computer algorithms for large and complex networks. ^[1]
