An MRP system is used to schedule each step. For motor assemblies, the lot size is 100 units and the lead time is one week. Eighty motors/wk are assembled. There are currently 110 units in stock. The MRP record for the motor assembly is as follows:

Assembly of the housing and drilling of the hole in the housing are done in two separate areas of the plant. The final motor assembly is done in a third area. It is proposed that the brace and shell assembly, drilling the hole, and final assembly of finished motors all be done in a single workcell. What would the BOM reflecting this change look like?

Answering Instruction:

Use the unit for D ( units/day), Q (units), C (days),and N (deliveries). Express your BOM answers in the format (D,Q,C,N) to be entered in the below box as follows: 300,20,3,1e.g. if your results are D = 300, Q = 20, C = 3, N = 1, enter 300,20,3,1
