Abstract selection scheme has been developed. This based on a simplified method, that determines ertices of the tolerance orthotope in the feasible constraints are linearized to determine vertex is crucial for the worst case design partial derivatives at the nominal point need This scheme minimizes the constraints f” v’the optimization problem. No more than 2 vertices ’2’’tolerance need to be considered during optimization f~ computional effort and time. selection scheme has been developed.
