The problem of equipment system reliability allocation is nonlinear constrained optimization. Through the penalty function method, the problem of the cost restriction is transformed to non-restraint optimization problem. The fitting function is presented by the complex index and MTBF (mean time between failures) of the equipment, the mathematical model of system reliability allocation is established based on the fitting function between the reliability and the cost of the unit. The numerical solution was given with the ode15s function which fits the stiff function by the MATLAB software, the results show right convergence and stability when the penal factor was changing. This paper indicates that the internal penalty function method to system reliability allocation is feasibility.
