Modeling & maximizing burn-in effectiveness

A nonlinear model has been developed to find optimal burn-in times for all levels and optimal redundancy for every subsystem. It shows that reliability of the target system can be achieved by lowering the incompatibility or component hazards rates. The system reliability is susceptible to the compatibility level of the initial system. Burn-in times increase due to decreases in burn-in cost because it is more useful to burn-in items than to raise the subsystem numbers.
