Adding Tire Service The owners believe that adding tire replacement would increase revenues with a negligible increase to fixed (facility) costs other than tire inventory. However, in order to be competitive with the discount chains, Brutus must target a maximum of 30 minutes total time for each customer visit specific to tires since pricing was already competitive. They estimate that the time between arrivals for cars needing such replacement would be ten minutes. A dedicated and secure parking lot with a limit of 6 spots is available specifically for cars awaiting tire service. While service requirements vary, they estimate that a dedicated technician should finish up 3 tire service jobs each hour.

How many Servers (fractional values, if necessary, are OK) are required to achieve the Total time limit of < 30 minutes? Attach a printout (page 1 only!) of the appropriate Q2010 solution. Highlight the S solution. (HINT: Your time units can be in either minutes or hours; this does not affect the solution)
