New Approach to Comparison of Systems

One of the most important variables are about system lifetimes. In this paper, the concepts of coherent system , signature vector and calculation of reliability function and comparing two and three coherent systems are discussed. In this view, assume that all components of systems have identical independent distributed . comparison of systems is performed at two status: at the first one, assume that systems have the same lifetime distribution function and at the second status, two coherent systems have different distribution function. Results have been discussed.
