The operations manager of an instruments company is balancing an assembly line. The company needs to build 96 instruments per 24-hour day. The assembly line activities are: a. Draw the precedence diagram. b. If the daily (24-hour) production rate is 96 units, what is the greatest possible 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...
