Determine the number of containers required to support a lean process which uses $180$ parts per hour. The time for a container to complete a cycle $($move$,$ wait, empty, return, fill$)$ is $1\mathrm{.}5$ hours. A single container has a capacity of $5$ parts. An inefficiency factor of $0\mathrm{.}08$ is currently being used. $($Round any fractional result up to the next higher whole number Answer is complete but not entirel
