We will highlight the “points of interaction” of agents and system dynamics and try to show that model elements belonging to different approaches live a single space of AnyLogic model and can easily access each other.
#Anylogic models how to#
The goal of this tutorial is to show step‐by‐step how to build a combined AB+SD model in AnyLogic using one particular architecture. The choice of model architecture (how to partition the model into components, what to aggregate, which granularity to use, what behavior is best mapped to a process diagram, and what – to a statechart, etc) belongs mainly to the domain of art and intuition of the modeler and is outside the scope of this short tutorial. Any kind of mixed architecture is possible due to flexible object‐oriented AnyLogic modeling language. Moreover, you can combine different methods in one model: put agents into an environment whose dynamics is defined in SD style, use process diagrams or SD to define internals of agents, etc, etc. Add the following line to Java machine arguments in the experiment properties to make the model work in the recent updates 8.7.x: -add-opens java.base/java.langALL-UNNAMED. It would look very similar to what you have now, the key difference being that your request logic would live in componentDidMount (async, called on the client) rather than componentWillMount (not async, called on the server).AnyLogic allows you to build a simulation model using multiple methods: System Dynamics, Agent Based and Discrete Event (Process‐centric) modeling. The problem is that AnyLogic 8.7 switched to newer Java (from 9 to 11). You would make an AJAX request in componentDidMount, and set the component's state from the fetched data. The other option is to handle the api request on the client.
Inside your component, you'd be able to access the data via. On server side application is like this: var rootInjector = new Injector ( ) // setup server specific providers rootInjector. But in details, it is bit more complicated in my case(url generation, active url highlighting, handling scrolls when navigating, also it has possibility of nested routes and multiple views)Īll this is assembled together using DI container, in my case similar to angular2 DI container, but a lot simplified for my specific needs.Ĭomponents, models and actions are created using DI. To obtain a successfully trained policy, there are a couple factors that you can control in your AnyLogic model. The AnyLogic Company is a multinational team operating from the US and Europe with a global network of partners. In general main feature is to map location changes to stream of virtual DOM elements and meta information. Router - component responsible to handling location changes, In simple case something like:Īction = new Rx.Subject() action.switchMap(asyncRequest).subscribe(updatesSubject)Ĭomponents - Observables(stream of virtual DOM elements) combined from models, other components and actions ( I have a note about this, explaining how and why to create Observable React elements with RxJS), also now I am planning to add partial components (tuple from: react component, observables, observers, and properties. Discrete event simulation modeling should be used when the system under analysis can naturally be described as a sequence of operations at a medium level of. Rx.fer(fetchData).concat(updatesSubject).shareReplay()Īctions(or intents) - Observers used to collects user input, do something, and dispatch action results to subscribers models and/or other actions. Models - Observables with current state (initial data is loaded using superagent, then combined with other models and/or actions results).
views - React components without any logic (just a view).In general my application is structured as following: There is few ways to do build an isomorphic app, the some interesting from my perspective is: and īut, the most elegant way to do this, as I figured out for myself - is to organise asynchronous rendering for react components, in particular using RxJS. The idea of multimethod modeling is simple: to seamlessly integrate different methods of modeling and simulation to overcome the drawbacks of individual. I have some experience doing isomorphic app with React, and the main problem I faced is how to wait until all data would be loaded before first renderĪs already mentioned in comments, there is not only one way to do this, and it depends from your requirements. You need to somehow move it out form component, and pass actual data as props after it is fetched - for example as suggested in his answer. Fetching inside of component using componentWillMount is not a right place, in case when you need to render server side.
