(a) Generate the material requirements. You need a BOM for each of the three products (A, B, and C), beginning inventory levels, and scheduled receipts. The BOMs are shown in Figure. All items use lot-for-lot as the lot size rule. No beginning inventories exist. Lead time is two weeks for all items except items D and F, which have a lead time of three weeks. All other information is provided for you in Table.

(b) After completing the material requirements plan, develop a load profile for each work center for each week of the second quarter. Use the planned order releases and calculate the workload at each work center for weeks 14 through 26. The standard times are shown in the table. Use the load profiles to identify potential problems. The effective capacity at each work center is 960 hours each period.

The Newmarket International Manufacturing Company (NIMCO) was started by Marcia Blakely just two years after she finished graduate school. Her knowledge of mass customization has been the driving force behind NIMCO. The company produces three major custom products. Volume on the products is high even though each item is customized specifically for the customer. The products are processed through up to four different work centers. Even though each item is unique, the processing time at each work center is constant due to the sophisticated equipmentused.
