Chapter 13, Problem 11P
Determine material requirements plans for pans N and V and subassembly I as described in Solved Problem 3 for each of the following:
a. Assume that there are currently 100 Ns on hand and scheduled receipts of 40 Is and 10 Vs at the beginning of week 3. No Es are on hand: 120 Es are needed at the start of week 5.
b. Assume on-hand and scheduled receipts as in part a. Now suppose that 100 Es are needed at the stmt of week 5 and 55 at the start of week 7. Also, use multiples of these order sizes: N, 800; V, 200. Use lot-for-lot ordering for I.
C. Using your answer to part b, update the MRP for V, using the following additional information for each of these cases: (1) one week has elapsed (making it the start of week 2), and (2) three weeks have elapsed (making it the start of week 4).

The Harvey Motorcycle Company produces three models: the Tiger, a sure-footed dirt bike; the LX2000, a nimble cafe racer; and the Golden, a large
interstate tourer. The month's master production schedule calls for the production of 32 Goldens, 31 LX2000s, and 38 Tigers per 10-hour shift.
What average cycle time is required for the assembly line to achieve the production quota in 10 hours? 0.099 hours per motorcycle. (Enter your response
rounded to three decimal places.)
If mixed-model scheduling is used, how many of each model will be produced before the production cycle is repeated?
The greatest common divisor of the production requirements is
Therefore, the Harvey Motorcycle Company will produce Goldens,
LX2000s, and
Tigers. (Enter your responses as integers.)

- by the end of 2013, the IPL port was operational and the naphtha was flowing to the Himachal Fertilizer Corporation (HFC) plant in Central India after being granted the port contract in Summer 2012. The plant was located in an industrial area that had several pipelines in the general geographic area including a crude oil pipeline leading to a refinery, and a pipeline carrying pesticides to be processed and redistributed to local farms in the area. In July 2014, Ajay Patel, the logistics general manager received notification that there were some minor leaks along the pipeline that were being fixed. Workers in the area had experienced sudden headaches and lightheadedness and the company immediately moved to investigate the leak and address faulty seams that had eroded and weakened. The flow of naphtha was temporarily stopped for 72 hours so two portions of the pipeline could be removed, and the eroded portions replaced. Patel put enormous pressure on the repair team to get the repair…arrow_forwardin the MABE: learning to be multinational case report, what is the reccomended course of action?arrow_forwardIn the MABE case report what would be the reccomened course of action?arrow_forward
