So until I figure out where's the proper place to call my writeStatistics() function, I'm resorting to collecting the utilization the old-fashioned way: total busy time / total run time. software packages AnyLogic, Arena, FlexSim, SIMUL8, Tecnomatix Plant Simulation and WITNESS.

Wether you use AnyLogic, Arena, Simio, FlexSim or any other simulations Software in the market, when you develop a model using the discrete-events paradigm, you will get access to a number of blocks that you can connect with each other to generate a flow with agents or entities flowing. At the time I called the method, the statsUtilization had not updated the denominator. Discrete Events Simulation Models Creativity Exercise. How-to steps to build & simulate a simple single server queueing model in AnyLogic. However, I was calling a function writeStatistics() within my fModelComplete() function that writes out an() to the summary report. Compare price, features, and reviews of the software side-by-side to make the best choice for your business. Now, it's possible that AnyLogic has some internal logic that will correctly calculate these statistics at the end of the run, by updating the denominator to reflect the total run time. So the utilization reports 20 / 50 = 40% busy. In our example, the last time the statistics changed was at time 50, when the resource was released. The statistics were collected over a shorter period of time than I expected. That's shown by the width of the |-stats-| below. It turns out that the statsUtilization is only updated when the statistics change. This is illustrated in the diagram below.īut lo and behold, if you run this exact setup, you will see that an() = 40%, twice as high as you expected! Why is that? The expected utilization is 20 / 100 = 20% busy. The resource turns on at time 30, and turns off at time 50, for a total of 20 minutes of use. You can then call () to return the average utilization over time.īut! You'd better double-check to make sure that you get the value you expect!įor instance, let's say that the total run length is 100 minutes. Therefore, there are a variety of commercial (Simio, AnyLogic, Simul8, Arena, etc.) and non-commercial (SimPy, Salabim, etc.) software packages that enable. The continuous statistics are used for things like queue utilization or resource utilization, where the value persists in continuous time but only changes at discrete time moments (like an entity entering or exiting the queue, or a resource turning on or off).

Checking this will create an internal statsUtilization object, which is of type StatisticsContinuous. Each ResourcePool object has an 'enableStats' checkbox. dbr:Systemdynamics dbr:Hewlett-Packard dbr:Arena(software). Our AnyLogic gurus probably already know this, but I didn't.ĪnyLogic 6 will automatically collect statistics for you on your resources. AnyLogic is a multimethod simulation modeling tool developed by The AnyLogic Company. A weird thing just happened to me when calculating resource utilization.
