question 80

Multiple Choice

Use this scenario for the following question(s) .
The process design team at a manufacturer has broken an assembly process into eight basic steps, each with a required time, and predecessor as shown in the table. There are 7.5 productive hours available in a day and the manufacturer wishes to produce 400 units. Balance the line by assigning tasks to workstations to fill up as much takt time as possible. Break ties by assigning the longest task first.
$$\begin{array} { | c | c | c | } \hline \text { Task } & \text { Time } ( \mathrm { sec } ) & \text { Predecessor } \\\hline \text { A } & 45 & \cdots \\\hline \text { B } & 50 & \text { A } \\\hline \text { C } & 20 & \text { A } \\\hline \text { D } & 55 & \text { A } \\\hline \text { E } & 15 & \text { D } \\\hline \text { F } & 65 & \text { D } \\\hline \text { G } & 25 & \text { E } \\\hline \text { H } & 35 & \text { B, C, F, G } \\\hline\end{array}$$
