AZ Devices manufactures a number of different electronic devices. One of their products is AZ-750 calculator. Calculators are sold every day of the month, but are only produced at the factory 5 days per week, Monday through Friday. Their monthly demand for these calculators is 8140. The factory is open 8 hours per day. Assume an average of 22 working days per month in the factory. You will be using daily demand, so use this information to calculate the daily demand. LINE BALANCING - PRECEDENCE DIAGRAM Remember, the factory is open 22 days per month. The assembly line runs 8 hours per day. The following precedence diagram gives the necessary data to answer the line balancing related questions that follow. 17 A 61 71 G N 10 D 50 60 M 9 B 33 28 59 51 27 32 29 E F H LINE BALANCING - PROBLEMS Question #1 -Make sure this answer is correct before moving on. What is the CYCLE TIME that ensures the desired output rate? (NOTE: NEVER ROUND-UP YOUR CYCLE TIME!!! You should be able to figure out why this should never be done. Think about it.) Question #12 Using the CT calculated in Question #1, what is the idle time for this layout (in seconds)? Question #13 Using the CT calculated in Question #1, what is the efficiency of this layout? Question #14 Use the precedence diagram provided for this lab to answer this question. If workstation #1 is (I, D) (60 seconds) and workstation #2 is (A,C) (68 seconds) then which of the following would NOT be an acceptable workstation #3? a. BEF b. BJ c. BJE d. BJK e. GB f. BF Question #15 Use the precedence diagram provided for this lab to answer this question. If workstation #1 is (1,B) (59 seconds) then which of the following would NOT be an acceptable workstation #2? a. AC b. ADE C. DC d. ADJ e. EF f. EFD
