malseiari Posted May 12, 2014 Share Posted May 12, 2014 Greetings, I am building a model which requires 20 entities to arrive at the first hour then four hours of break with no arrivals . Then repeat the same pattern of arrival of 20 for one hour and four hours break in between. I have been using the arrival schedule and use the rate of 20 in the first hour and 0 in the next four hours . However I am not getting 20 entities exactly with this arrival schedule and it is always less than 20. Is there away to force the exact number of entities arriving per hour? Thanks M Alseiari Link to comment Share on other sites More sharing options...
CWatson Posted May 19, 2014 Share Posted May 19, 2014 The Source's 'Time Varying Arrival Rate' Arrival Mode uses the Rate Table to specify the average number of arrivals per hour (or time period). As noted in the Rate Tables and Source - Discussion and Examples help, the rate tables use a non-stationary Exponential distribution to calculate the rate based on the rate specified in the table - therefore, some hours you may get 20 entities, while other hours you may get 21 and others 18, etc. Link to comment Share on other sites More sharing options...
dsturrock Posted May 23, 2014 Share Posted May 23, 2014 One way to do this is to use an Arrival Type of Arrival Table. Link to comment Share on other sites More sharing options...
