A production line is to be designed to produce modems. The production tasks, their times, and their precedence requirements are shown in the table below. Task Time (min) Predecessor(s) a 0.6 - b 0.3 a c 0.8 - d 0.7 - e 0.4 c,d f 0.8 b,e g 0.5 f h 0.9 f i 0.2 g j 0.1 h,i
a. Develop the precedence diagram.
b. If the production line operates 8 hours per day, what is the maximum production rate and what is the minimum production rate?
c. Calculate the number of followers for each task (show your answer on the precedence diagram).
d. If the production line is targeted to produce 300 modems per day, what is the cycle time?
