Multiple Choice

Table 9.19
The Illinois Appliance Company is installing a line to produce a vacuum cleaner, and you, as the operations manager, are responsible for designing the line. The line has to produce 30 units per hour. The work elements to be performed are as follows, with the time needed and immediate predecessor(s) also shown.
$$\begin{array} { | c | c | c | } \begin{array} { c } \text { Work } \\\text { Element }\end{array} & \text { Time (sec) } & \begin{array} { c } \text { Immediate } \\\text { Predecessor(s) }\end{array} \\\hline \mathrm { A } & 55 & - - \\\text { B } & 45 & \mathrm {~A} \\\mathrm { C } & 25 & \mathrm {~B} \\\mathrm { D } & 20 & \mathrm {~B} \\\mathrm { E } & 40 & \mathrm {~B} \\\mathrm {~F} & 50 & \mathrm { D } \\\mathrm { G } & 70 & \mathrm { D } \\\mathrm { H } & 45 & \mathrm {~F} , \mathrm { G } \\\mathrm { I } & 20 & \mathrm { E } \\\mathrm { J } & 80 & \mathrm { H } , \mathrm { I } \\\hline\end{array}$$
