62 CHAPTER 3 QUESTIONS 1. What are time standards used for? 2. What is the definition of a time standard? 3. What three numbers make up a time standard? 4. What are the five techniques of setting time standards? 5. Which technique would be used when no workstation is available? 6. Which technique is the most popular? 7. Which technique would be used for maintenance work? 8. Which is the best technique for setting time standards? 9. Which technique is both a method and a time study technique? 10. Define takt time. 11. Calculate the pieces per hour and the hours per unit for the following: Time Standard Minute Pieces per Hour Hours per Piece 300 2.000 .450 050 12. Define measured or observed time, normal time, and standard time. 13. What is meant by allowances and what are the most common types of allowances? 14. How does standard time differ from normal time? 15. Given a 10-hour shift, if a total of 20 minutes is allowed for breaks and a 10-minute cleanup period is given at the end of the shift, determine the takt time. Assume 85 percent efficiency. During this shift, 2,500 units are to be built. 16. The average observed (measured) time for an operation is given as .570 min- ute. The operator is rated at 95 percent. Allow a total of 15 percent for PF&D. If the direct labor wages are $12 per hour, determine (a) normal time, (b) standard time, (c) pieces per hour, (d) hours per 1,000 pieces, (e) standard direct labor cost per unit, and (f) direct labor cost per unit as produced by this operator. 17. Three operations are performed on a part. If these operations produce 1, 3.5, and .5 percent scrap, respectively, determine the number of blanks required to begin the process if 5,000 finished units are required.92 CHAPTER 4 11. Rebalance Figure 4-11 by adding a fourth packout person and make a subas sembly out of SA3. Then answer the following: a. What is the total hours per unit? _ b. How many units per shift will be made at 100 percent? c. How many people are now used? d. What is the new 100 percent station? e. Is this a better balance? f. How much money is saved if you produce 700,000 units per year and the employees are paid $10.00 per hour? 12. What are the two primary layout orientations? 13. Balance the following assembly line to produce 1,500 units per 8-hour shift at 85 percent and 30 minutes personal time: Operation No. Time Standard 390 235 .700 .D UT A CO NO + 1.000 .240 490 14. Calculate the efficiency of the line in question 13. 15. Explain how adding personnel to a line can reduce cost per unit. 16. Define and contrast process-oriented and product-oriented layouts. 17. Define group technology and explain how it is implemented. 18. Explain the concept of work cell. 19. Given a takt time or Rvalue of .452 minute, balance the following line. What is the efficiency of the line? Operation No. Time Standard 455 .813 .233 081 945Autosave (D (R Home Insert Paste & Page 10f 1 Draw Calibri (Bo...
