NovThe File Chooser is only available on the professional version of AnyLogic. But its functionality is very easy to replicate with a little bit of JAVA magic. To illustrate this, I will create this example using a normal button on the Simulation Graphical Editor (before running the simulation) in order to select an Excel file and make […]

NovYou just built a model, everything works perfectly well and suddenly you have a request for a change (minor or major). You make the change; run the model and things look good. But how can you be sure that the model is working well in all possible cases? The larger the model, the more difficult it is[…]

NovWhen you are a JAVA developer, it is common to use classes to work with objects. But AnyLogic provides Agents, that are basically predefined classes with several built-in functionalities to work with entities in a simulation model. A beginner user will always use agents because with them it is very easy to define everything graphically. But sometimes[…]

NovOn this challenge I will show two little tricks and things you should think about when you are developing an agent based or hybrid model. In this particular case, we want to initialize 100 agents depending on the state of the other 99. Of course there may be other ways to develop the same model, but I[…]

This has been fed with quotes as “It doesn’t make[…]

OctHave you ever been in a situation where you want to generate a complex scenario in the simulation experiment but you have no idea how to do it? There are features in AnyLogic that require the simulation model to be on runtime mode in order to work and will not be available in the simulation experiment configuration[…]

OctUp to this date with AnyLogic 8.3, there is a bug that doesn’t let you generate an agent that has too many elements. The error is caused by the code generation mechanism creating a large constructor of presentation of Main, violating the Java limitation on the method size. The error thrown by AnyLogic is “The code of method[…]

SepBefore I start, don’t expect me to explain all these methodologies in detail since there is already a lot of material on the web that can help you. Wikipedia is good starting point with the following links if you are interested in the technical details: System Dynamics Discrete Events Agent-Based In business, industrial and socio-economic settings, System[…]
