1、Review Questions for Final ExamIMBAReview Questions for Final Exam: IMBA-Lanzhou University 2014I. True or False Questions:1. Production and operations management concepts and techniques are limited to manufacturing organizations.2. All production activities should start with the market place-what t

2、he customer values.3. POM interacts with most other management systems within the organization.4. Process selection is choosing the methods by which raw material inputs are transferred into product outputs.5. The first decision in creating a production system is defining the process technology.6. Th

3、e choice of type of manufacturing process is typically made according to production volume.7. The variable cost per unit is lower for continuous than batch processing.8. The volume of production is higher for assembly than job shop processing.9. The level of fixed cost is higher for continuous than

4、job shop processing.10. The routings of material are more complex for continuous processing than batch processing.11. The use of specialized equipment is less for continuous processing than batch processing.12. The level of automation is greater for job shop than project shop.13. The productivity of

5、 labor is less for continuous than batch processing.14. As production processes evolve from batch to continuous flow, the product line narrows.15. The primary advantage of CIM is in the integration of its component technologies.16. Product design and process selection is generally less formalized in

6、 services than in manufacturing.17. An essential feature of McDonalds success is customization in the production process.18. The major difference between a manufacturing and a service system is that manufacturing requires the production of a physical product while a service does not.19. The capacity

7、 of the production system defines the firms competitive boundaries.20. Design capacity refers to the amount that a company can produce under normal operating conditions.21. Economy of scale is minimized when a firm achieves the best operating level.22. One reason that it is difficult to balance capa

8、city with demand in different time periods is that each period may have a different best operating level.23. The general objective of a facility layout is to ensure a smooth work flow (in a factory) or a particular traffic pattern in a service organization.24. Of the 4 types of layouts discussed in

9、class, it would be unusual and unprofitable for one company to utilize a combination of one or more of these layouts in one operation.25. The CRAFT layout program will always yield an optimal solution.26. The basic difference between product layout and a process layout is the pattern of work flow.27

10、. According to Japanese Management, the top priority of production lines is the line balance.28. Facility location refers to the site selection of the plant (or service branch).29. The classical principle for job design considers only the efficiency of labor.30. Close control over the work flow is o

11、ne of the advantages of specialization of labor.31. Vertical job enlargement gives the worker certain managerial powers over his own work.32. A job is said to be enlarged horizontally if the worker is involved in planning, organizing, and inspecting his own work.33. The concepts of job enlargement a

12、nd job enrichment were introduced primarily to increase output level.34. Elemental standard-time data is useful because it saves the time to repeat time studies for similar work-task sequences.35. One of the advantages of work sampling is that several studies can be carried on simultaneously.36. Pre

13、determined motion-time study require the assumption that the time required by many individuals performing the same work element will fall into a bell-shaped normal distribution.37. The work sampling method is based on the theory of statistical probability.38. The fundamental principle which underlie

14、s work sampling is that the number of observations is proportional to the amount of time spent in the particular activity of interest.39. The rating factor is an adjustment factor used to normalize the time for a job.40. Time study is useful in determining the standard times for tasks already being

15、performed, whereas predetermined motion time systems permit developing standard times for tasks not yet performed.41. Learning curves deal with the loss of a skill with time.42. The learning curve is most appropriate for automatic work.43. Learning curve theory is based on three assumptions: amount

16、of time to complete a task will increase each time a task is done, time will decrease at a decreasing rate, reduction in time does not follow a predictable pattern.44. A learning curve is a line showing the relationship between unit production time and the number of consecutive units of production.45. The amount of learning shown by a learning curve depends on the learning
