Chapter 15, Problem 2P
eXcel The Old Hickory Furniture Company manufactures chairs on the basis of the BOM shown below. At the present time, the inventories of parts and lead times are as follows:
The firm would like to produce 600 chairs in week 5 and 300 chairs in week 6.
- a. Develop a materials plan for all the parts.
- b. What actions should be taken now?
- c. Assume it takes one hour to assemble backs, one hour to assemble legs, and two hours to finish completed chairs. Total assembly time for all three types of assembly is limited to 1000 hours per week. Will this capacity constraint cause a bottleneck in assembly? If it does, what can be done?
