1) 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 (Ts) of 1.5 min, and (d) compute the balance delay for your solution.

2) Solve the previous problem but use the ranked positional weights method in part (c)

\begin{tabular}{lcccccccccc} \hline Work element or tasks & A & B & C & D & E & F & G & H & I & J \\ Time (min) & 0.5 & 0.3 & 0.8 & 1.1 & 0.6 & 0.2 & 0.7 & 1.0 & 0.9 & 0.4 \\ Preceding & & A & A & A & B,C & D & E & F & F & G,H,I \end{tabular}
