For the hybrid systems, the failure of machines is unavoidable. By introduced the idea of purchasing extra capacity to the system, a so-call blockage hedging point is obtained. Meanwhile, a near-optimal method is presented to determine the optimal buffer sizes. The continuous flow model of the unreliable manufacturing systems is considered and the control point policy is involved in. Numerical results not only testify the method and show us its application but also to some extent show the impact of the machines＇ failure rate on the optimal buffer size.展开更多
