Variability of output of station i becoming the arrival variability of station i+1 |
The output variability of a station denoted as cd2, is a function of the arrival variability of the station, its processing variability ce2 and its utilization u. For a single machine station, the mathematical relationship between the above quantities is as:
.
For multiple station machines (with m identical station) the relationship is as:
,
where, the utilization is now defined as the ratio of the single machine utilization divided by the number of stations m.
