Abstract:
On the basis of dynamic mathematical models, a comparative analysis of the
reliability of two types of networks (serial-parallel and parallel-serial) is performed in our
paper. Cases are analyzed when the numbers of sub-networks and units each sub-network are
constants, but also when the lifetimes of all units are independent, identically distributed
random variables (i.i.d.r.v.). The formulas for calculating the reliability of the related
networks are deduced. The invoked examples show us that Reliability of Serial-Parallel
Networks versus Parallel-Serial Networks depends only of number of the sub-networks and
number of units in the sub-networks.
