Consider departures from a single$-$machine station. What does departure time variability, cd$2,$ depend more on: interarrival time variability ca$2$ or effective processing time variability ce$2?$ Pick all options that are correct.$$

Group of answer choices

Answer depends on the station utilization

Answer depends on the number of machines at the station

For a high utilization station, departure time variability depends more on effective processing time variability

For a low utilization station, departure time variability depends more on interarrival time variability

Departure variability can change in unpredictable ways with interarrival time and effective processing time variabilities, especially when variability is high
