Aiming at the problem of software system reliability and cost distribution,an optimal model for software component cost distribution based on reliability is proposed.The software system reliability is defined as a function of component failure rate,the operational profile,expected component utilization,and the stated mission time for failure-free operation,and the details of building the optimal model and the steps of the solution are presented.In the process of solution,the nonlinear programming theory is used to solve the optimal model which is a multivariate constrained optimization problem.Finally,a simple example shows the optimal model for the distribution of software reliability and cost is feasible.
