The bottleneck (BN) of a production system is a machine with the strongest effect on the system's throughput. In this paper, a method for BN identification in serial lines with rework and Bernoulli machines is developed. The method can be applied using either calculated or measured data on blockages and starvations of the machines. For the case of calculated data, a technique for evaluating performance measures of Bernoulli lines with rework is developed. Along with these quantitative contributions, the paper provides three qualitative results. First, it shows that Bernoulli lines with rework do not observe the property of reversibility. Second, it demonstrates that downstream machines may have a larger effect on the throughput than upstream ones. Third, it demonstrates that BNs may be shifting not only because of changes in machine and buffer parameters but also due to changes in quality of parts produced.
Note to Practitioners-This paper shows how one can identify the bottleneck of a serial line with rework using data on blockages and starvations of the machines. Also, it demonstrates that the BN shifts when the quality buy rate is fluctuating. Finally, it shows that downstream machines in production lines with rework have a larger effect on the throughput than those upstream (which is unlike the serial lines with no rework where the effect of a machine is independent of its position in the system).
