A NOVEL AND UNIQUE APPROACH FOR DETERMINING THE SURVIVOR EQUIVALENCE FACTORS FOR COMPLEX SYSTEMS

ABSTRACT
In this paper, we provide a novel method to determine the survivor equivalence factors for coherent systems, whatever the unit's lifetime distribution and the struc­ture of the system. In order to determine the survivor equivalence factors for com­plex systems with independent units, we employ the idea of a survival signature and the Reliability Theory R package. Survival functions and mean times to failure are computed using the Reliability Theory package for systems were improved us­ing: reduction technique and duplication techniques, including: hot duplication, cold duplication with reliable switch, and cold duplication with unreliable switch. Survival survivor equivalence factors and mean survivor equivalence factors are taken into consideration as measures for comparing system improvements. For the new survivor equivalence factors method to be understood, numerical example for complex system is provided.
