Analysis of closed-loop production lines with Bernoulli reliability machines: Theory and application
提出一种迭代方法分析恒定载具数量的闭环生产线，将系统分解为小环并估计载具分布，从而计算生产率，并在汽车装配厂案例中验证了方法的准确性和效率。
In this article, an iteration approach is introduced to study closed-loop production lines with a constant number of carriers. A Bernoulli machine reliability model is assumed. The closed-loop system is decomposed into multiple small loop lines and further down to two-machine loops, in which the distributions of carriers are derived. Then an iteration procedure is presented to estimate the interactions between the small loops to modify the carrier distributions. Upon convergence, the system production rate can be estimated using these distributions. The convergence of the procedure is proved analytically, and the accuracy of estimation is justified numerically. It is shown that the method has good accuracy and computational efficiency. In addition, a case study at an automotive assembly plant is introduced to illustrate the applicability of the method.
