You could use a supervised algorithm for this.
Provide the number of people required on a given day at a given time for a time-frame (say past one month). A good algorithm can predict the number required now.

based on past experience and details available to them. ask managers to estimate on incoming customer tickets rate and ticket resolution rate per resource. keep reviewing the plan once every week.
