Problem $6-22($Algo$)$

Francis Johnson's plant needs to design an efficient assembly line to make a new product. The

assembly line needs to produce $15$ units per hour, and there is room for only five workstations. The

tasks and the order in which they must be performed are shown in the following table. Tasks cannot be

split, and it would be too expensive to duplicate any task.

b$.$ What is the workstation cycle time required to produce $15$ units per hour?

Note: Round your answer to $1$ decimal place.

Answer is complete but not entirely correct.

d$.$ Balance the line to use the fewest possible workstations to meet the cycle time found in part $($b$).$ Use

whatever method you feel is appropriate. What is the efficiency of your line balance, assuming the

line operates at the cycle time from part $($b$)?$

Note: Round your answer to $1$ decimal place.

Answer is complete but not entirely correct.
