Question $8(1$ point$)$

Consider a manufacturing process depicted by the following flowchart.

Station A has $3$ parallel operators, A$1,$ A$2,$ and A$3.$ Station C has $2$ parallel operators,

$C1$ and C$2.$ Each unit only needs to be processed by one of the operators A$1,$ A$2$ and

A$3.$ After being processed at Station B $($with a single operator$),$ a unit then needs to

be processed by either $C1$ or $C2.$ The process time of the individual operators are

given as follows.

$A1,A2,$ and $A3$ : $12$ minutes

B: $9$ minutes

$C1$ and $C2$:$6$ minutes.

The process initiates the production of a new unit every $19$ minutes. What is the

labor productivity $($in units$/$hour$)$ of this process?

Note: $1.$ Round your final answer to $2$ decimal places if it is not a whole number.

Operators are paid even if they are idle.
