I often see that the recommended place to install UserExtensions (dlls) is in the the user's documents (i.e. C:\Users\\Documents\SimioUserExtensions), but I would just like to point out for network admins that installing it to the Simio installation directory works too, and can save having to copy files on login to user directories. Example path: C:\Program Files (x86)\Simio\UserExtensions

I've created a tool which makes my life a bit easier when trying to code Design Add-Ins for Simio and I thought that I would share it with everyone else. Disclaimer: I'm an engineer that is mostly self-taught when it comes to programming so it may not work (all I know is that it works on my pc ). Also I know that it isn't the prettiest piece of software either. What the tool does is allow you to try c# code directly within Simio and evaluate the results. If you have ever used a dynamic programming language like Matlab or Mathematica then it will be familiar to you. Its like the command window in Matlab where you can enter commands without compiling. Its called a REPL (Read-Eval-Print-Loop). more info here: http://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop The code uses the Microsoft Roslyn Compiler API. more info here: http://en.wikipedia.org/wiki/Microsoft_Roslyn If you want to play around with the source code then you will probably need to install the Roslyn CTP. Download here: http://msdn.microsoft.com/en-gb/roslyn. I created the solution using Visual Studio 2012 and I believe that the roslyn compiler only works with VS 2012 at the moment. How to install: 1) Copy the SimioREPL folder from the zip file into either: C:\Program Files\Simio\UserExtensions or c:\Program Files (x86)\Simio\UserExtensions 2) The folder structure should be ..\Simio\UserExtensions\SimioREPL How to get started: 1) Create a new model in simio. 2) Select SimioREPL from the Select Add-In drop Menu (Project Home Ribbon) 3) Click "Insert Initializing Code" button. This inserts some code to get the whole thing going. You may need to change the directory of the dlls loaded if you are not using a 64-bit machine (delete the x86 part from the path). 4) Press the Execute button to evaluate the code. 5) You can now start playing with the interactive coding environment The bottom textbox displays the results from each execution loop. If no return values are given then it will display just the execution count. How to use (here is an example of how to use the tool): Enter c# code just like in a normal program, for example: int x = 10; You can find out the current value of a variable by entering its name without the ending semi-colon, for example: x or x*2 + 10 -3 This will display the value in the output text box at the bottom of the window. I've added the ability to use Write() and WriteLine(), just like in a console application. for example: WriteLine(object.ObjectName); If the code is invalid then the Exception message will be displayed in the results text box, and the input code will remain. If the code is valid then the input code is cleared. The context object is already defined. Use context as you normally would. Some example code Walkthrough: Add some objects to the model IIntelligentObjects intelligentObjects = context.ActiveModel.Facility.IntelligentObjects; IFixedObject sourceObject = intelligentObjects.CreateObject("Source", new FacilityLocation(-5, 0, -5)) as IFixedObject; IFixedObject serverObject = intelligentObjects.CreateObject("Server", new FacilityLocation(0, 0, 0)) as IFixedObject; IFixedObject sinkObject = intelligentObjects.CreateObject("Sink", new FacilityLocation(5, 0, 5)) as IFixedObject; ILinkObject path1 = intelligentObjects.CreateLink("Path",sourceObject.Nodes[0],serverObject.Nodes[0],null) as ILinkObject; ILinkObject path2 = intelligentObjects.CreateLink("Path",serverObject.Nodes[1],sinkObject.Nodes[0],null) as ILinkObject; [Execute] Move the source object intelligentObjects["Source1"].Location = new FacilityLocation(-4.5, 0, -2); [Execute] List all the nodes on the server object foreach(var node in serverObject.Nodes) { WriteLine(node); } [Execute] List all the objects in the model foreach(var ob in intelligentObjects) { WriteLine(ob.ObjectName); } [Execute] ---------- Hopefully you find this useful. If you improve the tool using the Source Code given then could you please repost the source code here in this forum topic. I'm sure that there are many things that can be improved by a proper programmer. What it really needs is intellisense . SimioREPL Source.zip SimioREPL UserExtension.zip

I have not looked too deeply at this specific problem for a while (there may be some obvious gotchas I have forgotten), however... have you looked at the Write step, and the bind excel sheet to table? You can bind excel sheets to tables, which will solve the feeding problem, and you can write out to csv files and use macros in the main spreadsheet to suck in that data. I have gone off excel sheet DRIVEN models though. The capability within Simio was just not there in making it easier for users. It is painful having to explain to end-users of models that they need to fix the absolute path references to the sheets... and that they must manually import the data into the tables if it caches incorrectly... etc. I only use excel for examining the results now, and for the rest I use experiments via the API and a written custom application.

In the current version of Simio, there is no fixed relationship between simulated time and real time. The model will run as fast as possible given the contraints of the number of simulation events and related "work" being done. The two other things that most dramatically impact simulation speed are Trace (when trace is on it excuted slower) and Animation (3D animation with a low speed factor runs slower). We have plans to provide an Emulation product for use in training and testing. Before that product is created, we will add the capability for Simio to run in real time or any multiple of real time. Speed Factor can be used to speed or slow the animation. Its main purpose is to improve the quality of an animation by decreasing the factor. This also has the side effect of slowing the animation so you can see certain events more clearly. Conversely, if you increase the speed factor, the animation will run faster, but in doing so, certain events (like movement on a path) might become jumpy or too fast to observe. Fast-Forward can be used to temporarily disable animation to allow the model to execute much fsater. Running an Experiment provides the fastest execution possible. Not only is animation and user interaction turned off, but it will also take full advantage of all processors on a multiprocessor machine, often running 2-4 times faster.
