QUESTION $4$

$4\mathrm{.}1$ An operator is tasked to operate two $(2)$ machines instead of one $(1).$

$4\mathrm{.}1\mathrm{.}1$ Use the given information to complete a multiple activity chart. $(6)$

Note: Load time $=4$ minutes

Unload time $=2$ minutes

Running time $=6$ minutes

$4\mathrm{.}1\mathrm{.}2$ Calculate the cycle time for both machines. $(2)$

$4\mathrm{.}1\mathrm{.}3$ Calculate the average cycle time for both machines. $(2)$

$4\mathrm{.}1\mathrm{.}4$ Calculate the utilization for the operator as well as the two $(2)$ machines. $(3)$
