# Operation management

1.    A department store chain is designing a layout for a new store. The store manager wants to provide as much convenience as possible for her customers. Based on historical data, the number of trips between departments per hour is given in the following closeness matrix. A block plan showing a preliminary layout is also shown.

Comp4U

Comp4U is a local computer store you will open that will build computers from components

when a customer places an order. We will have a local store where some sample computers

will be on display and we will build the computers in the back room on a lab bench using simple

tools such as screwdrivers and pliers.

You load up the software and test the computer overnight. We will also have some

sophisticated test equipment we will use to test the computer when finished. We can also

repair computers so the test equipment could be used for that.

Customers have the following options:

1 type of case

1 type of keyboard

1 type of mouse

2 sizes of monitors (19” and 21”)

2 different Intel CPU’s (fast, faster)

1 or 2 CD-DVD drive that can write DVD’s and CD’s (optional)

2 sizes of hard disks (big and you’ll never fill it up)

1 soundcard, microphone and speakers (optional)

1 wifi card (optional)

1 wired network card (optional)

1 type of motherboard

2 choices of RAM memory (a lot and really a lot)

Windows 7

Office software suite (optional)

Our objective is to build a computer within 2 days maximum, 1 day goal.

Prices will be competitive. We will discount on quantity orders.

Since volume is relatively low, you will have to buy the components from wholesale suppliers

(rather than directly from the manufacturers)

AE 1

For the Comp4U store, list the inputs, transformation process, outputs and feedback loops.

AE 2

For the Comp4U store, write a brief mission statement.

AE 3

For the Comp4U store, describe how you would use operations for a competitive advantage. Of the six

areas: quality, cost, delivery, flexibility, after sale service, or a broad product line, which would you

concentrate and why?

# Operations Management

Question #1

T&D electric manufactures high-voltage switches and other equipment for electric utilities. One line that is staffed by three workers assembles a particular type of switch. Currently the threes workers have fixed assignments; each worker fastens a specific set of components on the switch and passes it downstream on a rolling conveyor. The conveyor has capacity to allow a queue to build up in front of each worker. The bottleneck is the middle station with a rate of 11 switches per hour. The raw processing time is 15 minutes. To improve efficiency of the line, management is considering cross-training the workers and implementing some form of flexible labor system.

a)      What is the critical amount of WIP that is needed by this line?

b)      If the current throughput is 10.5 switches per hour with an average WIP level of 7 jobs what is the average cycle time?

c)      What is the practical worst case throughput of the line?

d)     Is there any room for improvement on this line?

Question #2

Floor-On, Ltd., operates a line that produces self-adhesive tiles. This line consists of single-machine stations and is almost balanced (i.e., station rates are nearly equal). A manufacturing engineer has estimated the bottleneck rate to be 2200 cases per 16-hour day and the raw process time to be 30 minutes. The line has averaged 1,500 cases per day, and cycle time has averaged 5 hours.

a)      What is the estimated average WIP level?

b)      How does the performance of the average throughput compare to the practical worst case throughput?

c)      What would happen to the throughput of the line if we increased the capacity of bottleneck station and held the WIP at its current level?

d)     If after process improvements the ten machines that required ten workers to run them are no longer needed. Instead five workers are now needed what would you do with the remainder of workers not working on that line anymore? (And please don’t fire them)
