    Based on the estimation method for the reliability of a failure-dependent series engineering system proposed in Reference [1] ,this paper studies further its optimal reliability distribution problem. Two optimization problems are solved. First is making the total pay-out of the engineering system be minimum when its reliability is restricted, and second is making the reliability of the engineering system be maximum when its total pay-out is constrained. The iteration procedures for finding the optimal reliability distribution is suggested according to the extremum conditions of the optimization problems. Several numerical examples show the validity of the iteration procedures.
