just need an answer to question 18!!

Work element or tasks A B D E F G H I J 0.5 0.3 0.8 1.1 0.6 0.2 0.7 1.0 0.9 0.4 Time (min) Preceding A A A B,C D E F F G, H, I 4.16 The letters in the table below represent work elements in an assembly precedence diagram. (a) Construct the precedence diagram and (b) determine the total work content time. (c) Use the largest candidate rule to assign work elements to stations using a service time (7.) of 1.5 min, and (d) compute the balance delay for your solution. .18 Solve the previous problem but use the ranked positional weights method in part (C). 19 The table below defines the precedence relationships and element times for a new assem- bled product. (a) Construct the precedence diagram for this job. (b) If the ideal cycle time is 1.1 min and the renneit
