Littlefield summary

[Kevin Roy]

Lakshmi and Rashida, I've taken a first stab at an outline of the summary  Perhaps you both can elaborate further to the attached.  We have a max of 4 pages, without appendices.

Please just let me know what else I can do to contribute.

Thanks,

Kevin

Hey Kevin,

That was quick! You seem to be a superman today!

It is a very good start for the document. We could improve it by adding some numbers  using the concepts from class -- since you are focusing on the process control, it would be best if we can include the processing times for each step (use this to identify bottleneck), process time and capacity for the whole operation, how wip builds up initially as we did not have enough capacity (taking a look at executive shirt case might help). Also, the process flow diagram is a good addition.

Kevin and Rashida,

Here is what our report should include:

Process analysis:  compute the processing time, capacity at each station. Use this to identify the bottleneck. The bottleneck's capacity, PR, CT become the lab's operational parameters. We need to calculate these when we started the operations, after each machine is added, and put them in a table for comparison

Queuing: almost all parameters listed in  the queuing slides -- utilization, waiting time, processing time, total time (again we need to do this when we started, after each machine is added). Add a table comparing these.

Inventory-- even though none of the model's available in the spreadsheet are applicable (except news vendor at the last stage), we could use concepts from what we covered in class, and how inventory decisions are taken.

How daily interest played a role in our decisions needs to be covered as well.

Things we did well-- reduce utilization, concept of scaled economies by using huge order quantities to reduce FC

Things we could have done better-- 1. Recognize early that high utilization means we need more capacity

2. Better control of batch sizes

3. As i think back, we could have better controlled the left over inventory by setting our reorder point a little higher for the last huge shipment, and place 1150 unit order. If our reorder point was set higher, this order would have gone thru when we still had control. And, once that went thru, we could have placed a 50 unit order just to make sure that we didn't run out of inventory.  (By the way, nobody in the team brought up the issue of adjusting the reorder point so that the large order would have gone when we had control, even though everyone is kept in the loop constantly). That would have helped.

If I missed anything that needs to be covered, please let me know. If I remember anything else, I'll add that to the list.

I plan to cover everything listed above, depending whatever you're able to cover.

Thanks for the guidance, Lakshmi.  I have this started, but in all likelihood will need to finish it this evening when I get to campus.  I expect to have it before our 9 p.m. meeting.

Lakshmi, attached is my summary and calculations.  Please note: I pasted the update below my earlier outline, in case any of that was helpful to your overall summary.

I've also included a process flow chart and table with processing and capacity rates as appendices to the word document.  See you soon.

Team,

Sorry for sending this so late. Kevin and Rashida reviewed this.  I will add some plots and submit this in about an hour.

If you see anything that needs to be changed, we can do that until a little before the class. Please let me know.
