Bottleneck identification methods
| Longest Queue | length of a queue analysis or a measurement of the waiting time of machines | |
| Longest Waiting Time | rate of utilisation of machines measurement | |
| Utilisation | rate of utilisation of machines measurement | Hopp and Spearman (2000) |
| Average Active Period/Active Period | measurement of the machine activity continuously | Roser et al. (2001/ |
| Process Time | material flow time in process measurement | Delpf et al. (2003) |
| Queue Time/Average Waiting Time | the waiting time before the process measurement | Faget et al. (2005) |
| Inactive Period | inactive time of machine measurement | Sengupta et al. (2008) |
| Turning Point | observation of blocking and waiting of processes | Li et al. (2009) |
| Bottleneck Walk | observation of processes and the level of inter-process resources | |
| Flow Constraint Analysis | takt time and the resource cycle time comparison | |
| C/T Corrected | cycle time and the degree of utilisation of each process measurement |
