The process-flow data is used to describe the movement
rate of lots between stockers. There is variability in
the lot movement rate. The source of data set is collected
from a wafer fab in Taiwan called a from-to-table (see
Table 1) shows the moves per hour in the process flow
from its mixed products. This data will be determined by
the influence of the distribution of the interarrival time
for the input rate of the simulation model. The input X
(hour per lot) value is the inverse of the value from the
from-to table. The data set is grouped by the stocker
name, so the parameter of the stocker can be found to
represent the behavior of the flow pattern for each
stocker from the statistical test.
