Consider the following batch flow process consisting of three process steps performed by three machines:
--> Step 1 --> Step 2 --> Step 3 -->
Step 1: Processing Time:
1 Minute/Part
Setup Time:
20 Minutes
Step 2: Processing Time:
2 Minutes/Part
No Set Up
Step 3: Processing Time:
1.5 Minutes/Part
No Setup Up
Work is processed in batches at each step. Before a batch is processed at step 1, the machine has to be set up. During a setup, the machine is unable to process any product.
(a) Assume that the batch size is 50 parts. What is the capacity of the process?
Worksheet in units/hour?
(c) What batch size would you choose?
Batch size is how many units?
(d) Suppose the batch size is 40 parts. What would be the average inventory after step 1?
Inventory is how many units?
