The model J wagon is to be assembled on a conveyor belt. 360 wagons are required per day. Production time per day is 450 minutes, and the assembly steps and times for the wagon are given. Find the balance that minimizes the number of workstations, subject to cycle time and precedence constraints. Our primary rule is to prioritize tasks in order of the largest number of following tasks. And secondary rule is to prioritize tasks in order of longest task time Task Task time(seconds) Task that must precede A 30 B 35 A C 30 A D 35 B E 14 C F 65 C G 40 E, F H 25 D, G A. Draw a precedence diagram. B. Find the cycle time and theoretically required minimum number of workstation. C. Balance the line (Assign tasks into workstations). D. Find the efficiency rate of this balancing
