Questions tagged [agent-based-modeling]

Agent-based modeling is a computer simulation method where agents make decisions based on their interactions with each other and their environment. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming.

From Wikipedia:

An agent-based model (ABM) (also sometimes related to the term multi-agent system or multi-agent simulation) is a class of computational models for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) with a view to assessing their effects on the system as a whole. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo Methods are used to introduce randomness. ABMs are also called individual-based models.

How to solve "java.lang.IndexOutOfBoundsException" problem via Agent-based modeling in Anylogic?

I met a problem when I want to assign the parking to each order, and then remove the parking-assined order from other parkings' order sets. This array list arr_assignedOrderSet has a size of 22, so it was supposed to iterate 22 times. But I have no…

Anylogic init state block

I'm developing an agent based combined with a dynamic process simulation. The problem is that the agent state not works properly, they move, as the are in state 1, 2 or 3, but the simulation show me that they are in the init state (state0). So how…

How to observe a turtle if it is not moving at that time instant ? (Netlogo)

in my model pedestrians are turtles so I want to observe when do they move and when they do not.i have given them property that if patch-ahead is not empty and they are not finding any empty patch in the cone 1 120, they will not move.so i want to…

How to process with ABM

In my bachalar work I am supossed to build an model of terrorist attack in Tokyo in 1995 (sarin gas). I have never done heard anything about ABM until about a month ago. Now I am even able to do some simple models. However I would welcome some ideas…

Draw distribution values from a parameter in AnyLogic

How can I change draw a value from a distribution stored in a parameter during runtime? Let's suppose my parameter value is "triangular (0.5 , 1 , 1.5)", for example. In my model, this parameter is called parDelayUnloading. I have many delays along…
