These two times may vary considerably when
very long operations are performed on a small percentage of the product
mix. For instance, consider the following situation. There are two variants
of the product being assembled, A and B, the product mix being 90% of
variant A and 10% of variant B. Suppose further that a workstation carries
out just one operation, say operation O1, and that O1 has duration 100
and only pertains to variant B of the product. In that case, the (average)
cycle time of the workstation will be 10 (10% of 100), because one in
ten assemblies takes 100, the remaining 9 assemblies taking 0. But the
max peak time will be 100, because each time the variant B is being
assembled, the operation O1 of duration 100 must be carried out.
