Determine an operator service rate for this situation. Then develop a queueing model for the 9-1-1 office using QueueingTools.xls. How many operators are needed to keep the probability a call is transferred to the police station under 2%? With this number of operators, how many are busy on average? Turn in a print out of your worksheet with the answers to these questions indicated. The worksheets in this spreadsheet implement the simple queueing models described in Chapter 6 of Banks, Carson, Nelson and Nicol, Discrete-Event System Simulation, 5th edition. Some important notes: 0. Go to the worksheet with the desired model. 1. Make sure that the base time units on all arrival rates, service rates and variances of service times are the same; do not mix hours, minutes and seconds. 2. The calculations in this spreadsheet are implemented in VBA, so macros must be enabled in Excel for the calculations to run. 3. Enter the required data (yellow cells), press Calculate, and read results below (light blue cells)
