Carefully read the Note on Process Analysis by Ramdas & Parkhill. This is in your course-pack.

1. Show how all the Run Time and Capacity numbers in the process flow diagram in Figure 3 (page 7 of the note) were calculated. There are 6 Run Time numbers and 6 Capacity numbers. These calculations are explained in the note. Create a table showing all details.
2. What is the capacity of the dry-cleaning process as a whole (from order taking to customer pickup and payment) over a 12-hour day?
3. Suppose capacity at Pressing is increased by 1 person and 1 pressing machine. What is the new capacity of the dry-cleaning process as a whole over a 12-hour day?
4. How much does the capacity of the dry-cleaning machine change if the batch size is increased to 120 items from 90 items?
5. How much does the capacity of the dry-cleaning machine change if tanks are switched only every 3 runs?
6. Suppose 200 customers drop off laundry over a typical 12-hour day. What is the utilization of each of the different stages of the dry-cleaning process? Will there be a problem? The different stages are: order taking, pre-treatment, dry-cleaning, pressing, packing, and pickup & payment. Do not consider the changes suggested in questions 4-
7. If the average number of clothes per customer increases from 3 to 4, which stages would be most impacted by this? Is the current system capable of dealing with this increase?
