B. None of the choices are correct C. Cube utilization and rack density D. All of the choices are correct
ANSWERS: 1. C: Answer option "c" is the correct answer. The means for testing the feasibility of a master planning schedule is found in RCCP, or roughcut capacity planning. RCCP operates much like an early warning system and is helpful in preventing bottlenecks from developing. The RCCP method is useful in quantifying and gauging the size of problems likely to arise from customer demand, productive capacity, and inventory planning. The data obtained from RCCP can flow to all work centers, includ.ng those involved in supply and production, and make it easier to match productive capacity to the master planning schedule. 2. D: The correct answer is "d," capacity requirements planning. CRP retrieves the order data from MRP. Using graphic or table representations of capacity and comparing those with hours available for manufacture gives a more precise account of material and capacity requirements needed to meet customer orders to the required specifications. In the CRP process, each manufacturing step is isolated, with the total number of operations at each work station multiplied by average run times. 3. B: The best answer is "b" (although it would be nice if "only accurate materials planning schedules" could be used... The demand and production environment is always changing, and a good materials planning operation should permit of the flexibility necessary to accommodate change. A properly detailed materials planning process also includes replanning alternatives and alternate scheduling. Maintaining the validity of a material plan involves setting priorities,
the use of modeling and whatif scenarios, and replanning to fit the changing environment. 4. A: ATP means availabletopromise, and is a measure of the amount of finished product that can be used to meet existing customer demand. In order to be counted as ATP, finished products must be available for delivery within the customer's specified delivery date. ATP is usually incorporated into information technology software and is usually based upon push or pull production models. MPS refers to the master production schedule; MRP means materials requirements planning; RCCP refers to roughcut capacity planning. 5. A: The correct answer is "a." The entire purpose of materials requirements planning is to maintain lean manufacturing through lean inventories and delivery of materials to the right place at the right time. Most MRP software aims for 99% accuracy in the bill of materials, inventory data, and the master production scheduling. Common errors in inputting data to MRP software systems is inaccuracy in calculating lead times, particularly in failing to recognize outside factors that can skew resultssuch as other products being made within the same factory. 6. D. Physical distribution and demand management Distributing materials, producing, and purchasing are all components of logistics. Logistics is the science of management quantity and location of products. 7. D. Final assembly schedule
All three choices belong in the distribution process except for final assembly which is a part of the manufacturing process. 8. B. Neither In a pull system, the production of items only occurs as they are pulled by demand. JustinTime is a methodology in which a pull system moves a product through the manufacturing processes. Centralized “push” systems are best for distribution networks so inventories can be best utilized throughout the distribution network. 9. C. Not enough information provided If the projected balance drops below zero, the planner will need to place the replenishment order according to the lead time. In this case, the planner would need to place the order in period 4 in order to support period 6 within the 2 period leadtime. 10. C. It is calculated from the MPS Used with assembletoorder and maketoorder companies, availabletopromise commits uncommitted portion of a company’s inventory or planned production. 11. C. Material requirements plan MRP would not be an input to the MPS, instead, the MPS is into the MRP. 12. B. Increase of forecast accuracy
The more detailed aggregate forecasts become, the more relative errors will increase. If user bias is not prevented from entering into forecast adjustments, they may vary widely. 13. B. Both Center 1 and 2 The center requiring the most product to be intransit in order for velocity to be maintained due to its distance from the source is Center 1.c 14. B. Manufacturing labor needs In production planning capacity is checked at a rough cut level and manufacturing labor needs may be determined. Component availability however, would not be determined as MRP would handle this. Component availability would only be checked at the production planning level if it were a scarce component. 15. B. Assembletoorder The final assembly schedule does not require separation in a maketostock company as products are stocked in their final assembled form for delivery to the customer. 16. B. Changes can be readily made during the firm period Free periods allow easy changes while slushy periods allow only minor changes over time. The third time fence, firm, does not allow for any changes unless the highest management level approves them due to significant cost impacts. 17. B. Trailer capacity only
Resource checks are allowed during distribution resource planning for critical distribution resources. Physical assets, capacity, storage, and available finances are all possible critical physical assets. 18. B. Supply warehouse safety stock Similar to the offset of leadtime in a MRP system in which purchase leadtime offsets the planned order release, lead time in a DRP system can be offset when the shipment planned matches the gross requirement of the supply warehouse. 19. B. Reorder point with safety stock The logic used in MRP is similar to the logic used in distribution resource planning which enables the planning of inventory at warehouse locations. Movements of inventory from one warehouse to another are established by leadtimes and because time phasing is used in the logic, inventory management which uses DRP in a warehouse network is most effective. 20. B. None of the choices are correct The largest capital cost of the distribution network is warehouse space and therefore, it must be used effectively. The density of and accessible space around racks must be optimized for efficiency as well as streamlining warehouse operations such as the picking process.
