the Terminal Company Is Attempting to Balance Its Assembly

question 149

Multiple Choice

Table 9.23
The Terminal Company is attempting to balance its assembly line of high-voltage electrical connectors. The desired output for the line is 50 connectors per hour, and the information on the work elements for this assembly line is as follows.
$$\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Work } \\\text { Elements }\end{array} & \begin{array} { c } \text { Time } \\\text { (sec) }\end{array} & \begin{array} { c } \text { Immediate } \\\text { Predecessor(s) }\end{array} \\\hline \mathrm { A } & 40 & - \cdot \\\mathrm { B } & 36 & \mathrm {~A} \\\mathrm { C } & 20 & \mathrm {~A} \\\mathrm { D } & 2 & \mathrm {~A} \\\mathrm { E } & 30 & \mathrm {~B} , \mathrm { C } \\\mathrm { F } & 34 & \mathrm { D } \\\mathrm { G } & 35 & \mathrm { E } \\\mathrm { H } & 5 & \mathrm {~F} \\\mathrm { I } & 15 & \mathrm { E } , \mathrm { H } \\\mathrm { J } & 40 & \mathrm { H } \\\mathrm { K } & 38 & \mathrm { G } , \mathrm { I } , \mathrm { J } \\\hline\end{array}$$
-Use the information from Table 9.23,and the longest work-element rule to balance this line.What is the efficiency of the solution?

• A) more than 90%
• B) 80-90%
• C) 70-79%
• D) less than 70%
