An improved algorithm for coherent-system reliability
This paper presents a simpler and more efficient algorithm (I_VT), based on the one proposed by Veeraraghavan & Trivedi (VT), to calculate system reliability using 'sum of disjoint products' and 'multiple variable inversion' (MVI) techniques. A proposition, a state space division idea, and a theorem are introduced. To compare I_VT with several well known MVI algorithms (viz, VT, KDH88, CAREL) the 4 algorithms are implemented on the same platform (Solaris), and the execution-time comparison shows the computational saving achieved by LVT is appreciable. ©1998 IEEE.
