Step 3 (Define Forecast—., output)Cell J15 is the forecast cell: Step 4 (Choose Number of Trials)500 trials were run. In addition, Sensitivity Analysis was enabled in the Options of the Run Preferences dialogue box. This allows for the generation of sensitivity analysis results later.Step 5 (Run Simulation)Step 6 (View Results) Additional Results Available with Crystal Ball174。Step 3 (Define Forecast—., output)Select the cell that contains the output variable to forecast (F17):click on the “Define Forecast” button in toolbar (or in the Cell menu),and fill in the Define Forecast dialogue box.Step 4 (Choose Number of Trials)Click on the “Run Preferences” button in toolbar (or in the Run menu):and select the number of trials to run.Walton Bookstore Simulation with Crystal Ball174。To run a simulation using Crystal Ball174。:1. Setup SpreadsheetBuild a spreadsheet that will calculate the performance measure (., profit) in terms of the inputs (random or not). For random inputs, just enter any number.2. Define Assumptions—., random variablesDefine which cells are random, and what distribution they should follow.3. Define Forecast—., output or performance measureDefine which cell(s) you are interested in forecasting (typically the performance measure, ., profit).4. Choose Number of TrialsSelect the number of trials. If you would later like to generate the Sensitivity Analysis chart, choose “Sensitivity Analysis” under Options in Run Preferences.5. Run SimulationRun the simulation. If you would like to change parameters and rer
