我们将具有确定性处理时间和指数故障及维修时间的 CONWIP CONstant 在制品生产线建模为封闭排队网络。我们推导出指定时间间隔内输出均值和方差的近似值，并给出该近似值表现良好的可计算条件。我们通过实证测试表明，该近似值是稳健的，并说明了其作为选择经济生产配额和 CONWIP 线卡计数程序的基础的有用性。
We model a CONWIP CONstant Work-in-Process production line with deterministic processing times and exponential failure and repair times as a closed queueing network. We derive an approximation for the mean and variance of the output during a specified interval and give computable conditions under which this approximation performs well. We show through empirical tests that the approximation is robust and illustrate its usefulness as the basis for a procedure for selecting an economic production quota and a card count for a CONWIP line.
