Repast Simphony is a tightly integrated, richly interactive, cross platform Java-based modeling system that runs under Microsoft Windows, Apple Mac OS X, and Linux. It supports the development of extremely flexible models of interacting agents for use on workstations and small computing clusters.

Repast Simphony models can be developed in several different forms including the ReLogo dialect of Logo, point-and-click flowcharts, Groovy, or Java, all of which can be fluidly interleaved. NetLogo models can also be imported.

Calling a Repast model with a list of model parameters

I have an agent-based model which is developed in Repast. To calibrate the model, I need to run the model with a list of parameters. And, use some optimization algorithms to find the best parameter set (minimizing some loss value). I wonder how to…

Repast - locate and track a specific agent using agent monitor

I have 500000+ agents which are added in the context but not in the display. Is there an easy way for me to locate a specific agent (without displaying it) and track its property change over time using the agent monitor like below:

Repast: set different color for different edges

I have two types edges in my supply chain model: demand_links and supply_links. the default color is gray for all links. But I want to change the color of demand_links to red each time the attribute of the demand_link is changed (Note:the edge is…

Repast: plot the KPI of each single agent

Instead of plot the aggregated average of the entire agent set (retailers & distributors), I want to explicitly plot the KPI of each single agent(e.g. retailer-1, retailer-2....). I read the non-aggregate plotting method but it did not work well.

Repast Java: scheduling agent and global behaviors in a structural way

I am previously working with Netlogo for years and I am very much getting used to developing the agent-based model based on a set of procedures. An example of supply chain simulation model structure looks like below: ;;the main simulation…

Repast: Is there a link type of agent like Netlogo?

I used Netlogo a lot and I found it is not constraining anything I want to build. However, I am interested to learn Java based ABS for bigger engineering project. One of the key question is if there is a agent type as link (directed and undirected)…
