Using the arrival rates from the lunchtime rush example, it seems sensible to vary the number of servers so that more servers work during the busy hours. In particular, suppose management wants to have an average of three servers working (in parallel) in any half-hour period, but the number working can vary across periods.

Also, assume that each server has a service rate of 16 customers per hour. Experiment with ways to deploy the servers, assuming that at least one server must be working each half-hour period. For example, at one extreme, you could have three servers working each half-hour period. At the other extreme, you could have a single server working all but one of the halfhour periods, and 13 servers working during the other half-hour period. Defend the deployment you think works best in a brief report.
