Table 10.16
Balance the following lines for an output rate of 5 pieces per hour, using the
longest work-element time rule. The times are in minutes (not seconds) .
$$\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Work } \\\text { Element }\end{array} & \text { Time (min) } & \begin{array} { c } \text { Immediate } \\\text { Predecessor(s) }\end{array} \\\hline \text { A } & 7 & - \cdot \\\text { B } & 5 & - \cdot \\\text { C } & 3 & - \cdot \\\text { D } & 4 & \cdots \\\text { E } & 2 & \text { A, B } \\\text { F } & 5 & \text { C } \\\text { G } & 6 & \text { D } \\\text { H } & 7 & \text { E, F } \\\text { I } & 11 & \text { F, G } \\\text { J } & 4 & \text { H, I } \\\hline\end{array}$$
