an assembly process involves the following ten atomic tasks with the corresponding process times and precedence constraints: task process time (secs) immediate predecessors a 10 - b8- c 11 a d 7 c,b e5c f 15 d,e g 11 - h 15 g i 10 e,h k 5 f,i a. using the rank positional weight heuristic to design a production line for this assembly process with a production rate of 60 parts per hour. b. suppose tasks a and i have to be performed at the same station since they need to share some equipment, what is the maximum possible hourly throughput that can be obtained for this assembly process ? c. suppose you are limited to 3 work stations what is the best cycle time that may be able to achieve ?
