The Casual Furniture Company

Effective requirements planning is essential for CFC’s performance, and it uses MRP for planning. The MPS and MRP records are shown for one of CFC’s products, part number 4 × 3-01, a four-foot-high and threefoot-wide standard depth oak bookshelf. The BOM as a product structure diagram is shown in Figure XXXXXXXXXXCFC uses one-week time buckets and a planning horizon of eight weeks.

The component lot size, lead time, available inventory and safety stock are shown in Figure 14-20. Two associates work in the cutting department, making the available capacity 80 hours per week,

Questions
1. Develop the MRP for all of the components.
2. During week 1 of the plan, the bracket supplier notifies CFC that the order for 600 units will not arrive as planned. Instead, 300 will arrive this week and 300 will arrive next week, instead of all 600 arriving at the same time. Will this affect production and, if so, to what extent?
3. Now that the plan has been developed, is it feasible to consider the capacity of the cutting department? What recommendations do you have?
4. If you could change the lead times or lot-sizing policies used for any of the components, what changes would you make? Why?
