• Question 1271:

  Materials requrements planning (MRP)sometimes results in

  A. Longer idle periods

  B. Less flexibility in responding to custoemrs

  C. increased inventory carrying costs

  D. Decreased setup costs

  Correct Answer: D

  Among the benefits of MRP are reduced idle time,lower setup costs,lower inventory carrying costs,and increased flexibility in responding to market changes.

• Question 1272:

  In contrast to just-in-time manufacturing,materials requirement planning is a

  A. Push system

  B. Pull system

  C. Automated system

  D. Manual system

  Correct Answer: A

  MRP is a push system,that is,the demand for raw materials is driven by the forcasted demand for the final product,which can be programmed into the computer.this is in contrast with just-in-time manufacturing,which is a pull system,meaning items are pulled though production by current demand,not pushed through by anticipated demand.

• Question 1273:

  A company uses a planning system that focuses first on the amount and timing of finished goods demanded and then determines the derived demand for raw materials,components,and subassemblies at each of the prior stages of production.this system is

  A. An economic order quality model

  B. Materials requirement planning

  C. Linear programming

  D. Just-in-time purchasing

  Correct Answer: B

  Materials requirements planning(MRP)is a system that translates a production schedule into requirements for each components needed to meet the schedule.it is usually implemented in the form of a computer based onformation system designed to plan and control raw materials used in production.it assumes that forecasted demand is reasonably accurate and that suppliers can deliver based upon this accurate schedule.MRP is a centralized push-through systeml;output based on foecasted demand is pushed through to the next department or to inventory.

• Question 1274:

  Which of the following is not a correct comparison of a just-in-time system with a traditional system?

  Traditional Just-in-time

  A. Longer lead times Shorter lead times

  B. Inventory is an asset Inventory is a liability

  C. somescrab tolerated Zero defects desired

  D. Lot size based on immediate need Lot size based on formulas

  Correct Answer: D

  Lot sizes based on immediate need are typical of just-in-time systems,while lot sizes based on formulas are characteristic of traditional inventory management systems.

• Question 1275:

  Just-in-time production is also called

  A. Kaizen.

  B. Lean manufacturing

  C. Activity-based management

  D. Backflush costing

  Correct Answer: B

  To implement a just-in-time(JIT) approach to inventory management and to eliminate waste of materials,labor,factory space,and machine usage,the factory is reorganized to permit what is often called lean production.plant layout in a JIT-lean production environment is not arranged by functional department or process but by manufacturing cells(work cells).central support departments are reduced or eliminated,space is saved,fewer and smaller factories may be required,and materials and tools are brought close to the point of use.

• Question 1276:

  Which of the following terms is not connected with the employment of just-in- time(JIT)manufacturing?

  A. Cells

  B. Kanban

  C. Lean production

  D. Safety stock

  Correct Answer: D

  Safety stock involves always keeping enough raw materials on hand to overcome the effects of an interruption in supply.in a JIT system,manufacturers arecompletely depended on the reliability of their suppliers in delivering raw materials as they are needed.keeping safety stock undercuts the entire philosophy of JIT.

• Question 1277:

  The physical reconfiguration of equipment that often accompanies the institution of a just-in-tme manufacturing regime is described as the creation of

  A. Cells

  B. Kanbans

  C. Electronic data intercharge

  D. tickets

  Correct Answer: A

  Plant layout in a IT-lean production environment os not arranged by functional department or process but by manufacturing cells (work cells).cells are sets of machines,often group in semicircles,that produce a given product or product type.

• Question 1278:

  Which of the following is not a benefit of lean production?

  A. Reduced setup time.

  B. Lower central support costs.

  C. Lower training costs.

  D. Improved on-time delivery.

  Correct Answer: C

  Since every worker in a manufacturing cell must be able to operate every piece of machinery in the cell,reduced training costs do not necessarily accompany the deployment of lean production.

• Question 1279:

  Which of the following internal controls is not one typically eliminated when a just-in- time inventory system is introduced?

  A. Sophisticated inventory tracking system.

  B. Central receiving dock

  C. Statical methods for quality assurance.

  D. Hard copy receiving report.

  Correct Answer: C

  Under a JIT system,the quality of parts provided by suppliers is verified by use of statistical controls rather han inspection if oncoming goods.storage,counting,and inspection are eliminated in an effort to perform only value-adding work.

• Question 1280:

  A firm that is deploying just-in-time manufacturing for the first time will

  A. Establish contracts with many suppliers since an interruption in spply is extremely disruptive of the production process.

  B. Establish contracts with a few carefully chosen suppliers since an interruption in supply is extremely disruptive of the production process.

  C. Maintain a carefully calibrated safety stock since interruption in supply are inevitable.

  D. Acquire considerable computer processing capability to manage the demands of the data-dependent kaban inventory management system.

  Correct Answer: B

  In a JIT system,the suppliers'dependability is crucial.organizations that adopt JIT systems develop close relationships with a few carefully chosen suppliers who are extensively involved in the buyer's processes.
