MGSC 6090 - Operations and Supply Chain Management Homework 1

Assignment Task

1. Give an example of a firm that is a top performer in its industry ( other than the examples mentioned in class ). Identify one main operations competitive priority for this firm (cost, quality, flexibility, or delivery). Identify two operational characteristics that allow this firm to compete on this dimension (i.e., that makes this dimension an actual competitive capability )..

2. A diagram of a manufacturing process is given below. Assume a pull system. Note that the abbreviation AT stands for Activity Time and C stands for Each operation has one FTE (full- time equivalent = equivalent of one person working full-time) and units are processed individually (i.e., m=1).

1. What is the capacity of Operation 1?

2. What is the activity time of Operation 2?

3. What is the bottleneck?

4. What is the process capacity?

5. If demand is 20 units per hour, what is the utilization of the employee working at Operation 3?

3. A clinic is restructuring its CAT scan Number of FTEs for each operation and capacity for each FTE working at a given operation is shown in the following Table:

a. This is the current process flow diagrama:

What is:

• the capacity of each operation?
• the bottleneck?
• the process capacity?
• the rush order lead time (i.e., lead time assuming the process is empty)?
• the process throughput if a new customer arrives every 3 minutes on average?
• the average labor utilization if a new customer arrives every 3 minutes on average? Assume a pull system (i.e., every operation has the same average throughput aligned with the average throughput of the process).

b. Changes are made to the CAT scan process shown in (a), which results in the flow diagram shown below. Assume that each customer has a CAT scan that needs to be analyzed (operation D) while the customer goes through operations B & C. The customer and his/her CAT scan are then reunited (which could involve some wait) before going together through operation

What is:

• the bottleneck?
• the process capacity?
• the rush order lead time?
• the process throughput if a new customer arrives every 3 minutes on average?
• the average labor utilization if a new customer arrives every 3 minutes on average? Assume again a pull

c. What difference do you see when comparing the layout in question 3.a and question 3.b? What measure(s) that you previously computed are affected by the change in layout seen in 3.b? Explain in your own words why this/these measure(s) would change?
