![]() So instead of the first number 20 you type sLoRetailer, then you replace the 80 with SHiRetailer, then the next 20 you replace with sLoWholesaler, then SHiWholesaler, then sLoFactory, and finally SHiFactory. ![]() Then type in each field in the column "Expression" the same word as you see on the general property page of the Simulation experiment. In the "Properties" view of this experiment go to the "General" tab and choose "Freeform" instead of "Varied in range" and put a large number in the box asking for the "Number of runs", e.g.: 1,000,000,000. Now we have created a new experiment with which we can optimize the parameters. Leave everything else as it is and click "Finish". The best type of experiment for this task is a "Parameters Variation" experiment, so choose this and choose a name for it, e.g. Now we need to add a new experiment which we can run to serve as our evaluation function. Choose the file you just downloaded, make sure "Import to model folder is ticked" and click "Finish" to add the library. In the properties window of this model in the section "Jar files and class folders required to build the model:" click the add button. Then switch to AnyLogic 6 again and click the model icon in the project view (should be called "Supply Chain" if you followed the model name suggestion above). your Downloads directory you should not download it into the model folder already). Now download the H元 External Evaluation Java library to a place that you remember (e.g. That way it will save it in a folder called "Models" in your user's directory. For the sake of simplicity just put "Supply Chain" in the box that asks for a model name and leave everything else. Preparing the Simulation Model in AnyLogic 6įirst save the model in a new location. In total we have 6 decision variables, one target variable and one constraint on the output. Each echelon in the chain uses an (s,S) ordering policy. The optimization goal is to minimize the sum of all costs in the supply chain while satisfying a certain service level for the end user. There is also an Optimization Experiment in this model which uses the proprietary optimization package OptQuest. After you opened the model you can try to run the Simulation. You can open it either on the Welcome page after starting AnyLogic 6 or by choosing "Sample Models" from the Help menu. The model which we are going to optimize with HeuristicLab comes preinstalled with AnyLogic 6 and is called Supply Chain. If you go through this tutorial you will hopefully get an idea on how to solve your specific problem and implement the connector in your model. This howto is written as a tutorial by taking one of the sample models that ships with AnyLogic and add connectors to optimize its parameters with HeuristicLab algorithms. We assume the reader is familiar with xj technologies AnyLogic 6 and has basic understanding of the Java programming language. If you prefer a slide version of this tutorial with images, please download the PDF tutorial of optimizing external applications and follow the instructions in Demonstration Part I therein. optimize parameters of AnyLogic 6 simulation models ![]() Have a go, and help spread the AnyLogic word in your language! Go straight to the subs translator (desktop only).How to. For accepted translations we'll give rewards, shout-outs, links, and recognition. ⭐ Get a t-shirt! On YouTube you can add translations (click the 3 dots below the bottom-right corner of the video). Try out custom process blocks in the demo model or in your models, how useful are they? Let us know in the comments below and also what else could be useful for your simulation modeling! If you are ready to move on to the next how-to, check out the how-to playlist. These allow process logic to be grouped together, simplifying the look of a model and enabling easy re-usability of the grouped blocks. Further guidance on creating custom blocks is available in the AnyLogic help documentation.Īfter some examples of complex model logic, the video introduces the custom block. The video uses a wholesale warehouse example model that you can find in the AnyLogic Supply Chain and Logistics example models, or for download from the AnyLogic Cloud. How to make your process flowcharts simple and clear by creating reusable custom blocks of logic.
