"? Statistical distributions are seldom provided in real-world simulation settings ? Specification of arrival rates and service rates require data collected over time inthe physical process ? Statistical distributions may be fitted to the data for use in simulation modeling ? Two tools are available to students ? Stat::Fit limited size version distributedwith ExtendSim ? JMP Statistical software? Limited to 50 dataelements ? Data should representservices times orinterarrival times ? Within ExtendSim, go to“Run” menu ? Select “Launch StatFit”? Data may be entered by hand? Select “Input” Menu ? Select “Input Data” ? Enter data into right-hand column ? Data may be copied from Excel and pasted intoStat::Fit ? Select “Input” Menu ? Select “Input Data” ? Copy column of data from Excel (do not exceed 50observations) ? Paste data into right-hand column? Select “Fit” menu ? Select “Auto::Fit” menu option ? You may alternatively click on the “Auto::Fit” buttonon the tool bar ? Check “continuous distributions” radio button ? “The Distribution Is:”select “assigned bound” ? “Lowest Available Value:” enter “0” ? Click “OK”? Distribution results will be provided along with results of hypothesis test ? Choose from distributions with “do not reject” for value of “acceptance” ? Choose the “do not reject” distribution with the highest rank ? Use parameters immediately following the distribution name in simulation model? Select “Utilities” menu ? Select “Distribution Viewer” menu item ? Select the appropriate distribution from the pull down menu ? Enter distribution parameters to match fitted distribution"
