Abstract

This paper considers stochastic comparison for parallel systems with two exponential components. For a given such system, we identify a region, such that, if the hazard rate pair of another parallel system lies in that region, then there exists likelihood ratio ordering between the two systems. The new results presented in this paper extend most existing ones in the literature.
