运行相依不可靠生产线的控制参数灵敏度估计

CONTROL PARAMETER SENSITIVITY ESTIMATE IN AN OPERATION DEPENDENT UNRELIABLE PRODUCTION LINE

机器发生故障是运行相依的两级生产线系统，在阈值策略控制下，给出一种简单的算法，得到性能指标关于控制参数灵敏度的无偏估计．仿真例子验证了算法的有效性．

For a two-stage production line system with operation dependent unreliable maechines, regulated by a threshold control policy, a simple algorithm is presented to get an unbiased estimate of the gradient of the performance index with respect to control parameters. Simulation example is given to illustrate the effectiveness of the algorithm.
