Consider the following batch-flow process consisting of three process steps performed by three machines:

Step 1→→→→Δ→→→→ Step 2 →→→Δ→→→→ Step 3
Activity Time: Activity Time: Activity Time:
0.25 Minute/Part 0.20 Minute/Part 0.15 Minute/Part
Setup Time: Setup Time: Setup Time:
30 Minutes 20 Minutes 45 Minutes

Work is processed in batches at each step. Before a batch is processed at a step, the machine at that step must be set up. (During a setup, the machine is unable to process any product.) Assume that there is a dedicated setup operator for each machine (i.e., there is always someone available to perform a setup at each machine.)
(a) What is the capacity of step 1 if the batch size is 35 parts?
(b) For what batch sizes is step 1 (2, 3) the bottleneck?

Answer:

Explanation:

Capacity: The maximum flow units that can be completed by a resource per unit time is called capacity. The following formula is used to calculate the capacity of a batch with set up times:

Bottle neck: The resource with the lowest capacity in a process is called bottle neck.

In a process, the set up time influences the capacity of the process. If there are more set up times, the capacity of the process will be decreased.
