calculators per hour. (Enter your response as an integer.)
B. What cycle time corresponds to this maximum output rate?
C. If a worker is at each station and the line operates at this maximum output rate, how much idle time is lost during each? 10-hour shift?
D. What is the line's efficiency?
Dr. Lori Baker, operations manager at Nesa Electronics, prides herself on excellent assembly-line balancing. She has been told that the firm needs to complete 96 instruments per 24-hour day. The assembly-line activities are: a) Draw the precedence diagram.b) Tf the daily (24-hour) production rate is 96 units, what is the highest allowable cycle time?c) If the cycle time after allowances is given as 10 minutes, what is the daily (24-hour) production rate?d) With a 10-minute cycle time, what is the theoretical minimum number of stations with which the line can be balanced?e) With a I 0-minute cycle time and six workstations, what is the efficiency?f) What is the total idle time per cycle with a I 0-minute cycle time and six workstations?g) What is the best workstation assignment you can make without exceeding a I 0-minute cycle time, and what is its efficiency?

- SITUATION: A company is about to begin production of a new product. The manager of the department that will produce one of the components for the product wants to know how often the machine used to produce the item will be available for other work. The machine will produce the item at a rate of 200 units a day. Eighty units will be used daily in assembling the final product. Assembly will take place five days a week, 50 weeks a year. The manager estimates that it will take almost a full day to get the machine ready for a production run, at the cost of $300. Inventory holding costs will be $10 a year. QUESTION: Suppose the manager decides to increase the run size of the new product. How many additional units would be needed just to accommodate the other job?
