Unformatted text preview: BUSI 403 Problem Set E Fall 2008 Due: 10/02/08 Problem 1 a. Develop an indented bill of materials showing the low level codes for each component. Hint: Start by drawing the product structure tree. The product structure tree for an alternator is as follows (not required for credit): Alternator CKT (1) PTN (2) BLT (2) BRN (1) BLT (4) WSR(2) FLW (1) FWN(1) WSR(1) SRL (2) Note: Number in brackets indicates the quantity required at next highest level. Item Quantity Level - 0 1 1 2 2 Bolt (BLT) 2 3 Side rail (SRL) 2 3 Bearing (BRN) 1 2 Washer (WSR) 2 2 Bolt (BLT) 4 3 Flywheel (FLW) 1 1 Flywheel nut (FWN) 1 2 Washer (WSR) 1 2 Alternator Crankshaft (CKT) Piston (PTN) 1 BUSI 403 Problem Set E Fall 2008 Due: 10/02/08 b. Calculate the total number of units of each distinct component needed to make one alternator; list in the order of their low level code in the BOM. Item Quantity Level Alternator 1 0 Crankshaft (CKT) 1 1 Flywheel (FLW) 1 1 Piston (PTN) 2 2 Bearing (BRN) 1 2 Washer (WSR) 3 2 Flywheel nut (FWN) 1 2 Bolts (BLT) 8 3 Side rails (SRL) 4 3 Note: If you did not include Alternator in part b that is fine. 2 BUSI 403 Problem Set E Fall 2008 Due: 10/02/08 Problem 2 Week MPS replenishment MPS order releases 1 0 700 Item: A (LT=1 wk, SS=0, L4L) 2 3 4 700 450 600 450 600 850 5 850 450 6 450 500 7 500 600 8 600 MRP charts: The gross requirements for item D are derived from the planned order releases of item A. Recall that each item A requires 2 units of item D, so the gross requirement for item D in week 1 is 700*2=1400.

Each item D requires 1 unit of item E, so the gross requirements for item E are equivalent to the planned order releases of item D.

For example, the planned order release for item D in week 1 is 0 and for item E is 600, so the gross requirement for item F in week 1 is 0 * 2 + 600 * 2 = 1200.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
