This paper illustrates the capacity of a stigmergic routing control model to automatically find efficient routing paths for active products in flexible manufacturing systems (FMSs) undergoing perturbations. The proposed model is based upon a functional architecture with two levels: a virtual level in which virtual active products (VAPs) evolve stochastically in accelerated time, and a physical ...

Simulation techniques used to generate complex biological models are becoming promising research tools in oncology. Using a general Complex Adaptive Systems model that can be tailored to map various phenomena, here, we describe how this model applies to tumor growth. The multi-agent modeling environment is generated using Netlogo. The stochastic model consists of active objects including normal...

We present initial efforts made to model the spread of the drywood termite in Angra do Heróısmo, Azores, using an agent based modeling approach. First we describe how a simple Cellular Automata (CA) model was created in Netlogo to simulate the spread of the species based on simple assumptions concerning the ecology of the species. A second step was taken by increasing the complexity of the init...

In this work we investigate how two autonomous agent swarms, controlled by the BEECLUST algorithm are able to cooperate. The task is to locate two different target areas, which are located near each other. Therefore we developed an individual-based NetLogo model to simulate two different agent swarms moving in a temperature gradient. Both agent swarms are controlled by the BEECLUST algorithm, w...

J. Gary Polhill's forum paper in this issue was an invitation to try the OWL extension on a model that was written more than a year ago. Download and installation was a matter of a few minutes, extending the old model with a few lines as shown in the paper was not a problem either, visualising the OWL output with different versions of Protégé was a little more difficult, but in the end showed i...

While student populations in higher education are becoming more heterogeneous, recently several attempts have been made to introduce online peer support to decrease the tutor load of teachers. We propose a system that facilitates synchronous online reciprocal peer support activities for ad hoc student questions: the Synchronous Allocated Peer Support (SAPS) system. Via this system, students wit...

The choice of a basic modeling approach, either population-level or individual-based (IbM), is an important decision to be addressed according to the problem at hand. We present an IbM that simulates the dynamics of a bacterial bioreactor under different handling protocols. The main objective is to provide a simulator that will be easily understood, adjusted and used by non-experts. The model h...

Connected Chemistry (named CC1 to denote Connected Chemistry Chapter 1) is a computer-based environment for learning the topics of gas laws and kinetic molecular theory in chemistry. It views chemistry from an ‘‘emergent’’ perspective, how macroscopic phenomena result from the interaction of many submicroscopic particles. Connected Chemistry employs agent-based models built in NetLogo (Wilensky...

The goal of this project is to apply system dynamics modeling to a basic instance of the contemporary issue of sustainability. System dynamics modeling is especially well-suited to the topic of sustainability; the flows and stocks involved with this sort of modeling are the keys needed to express the relationships between quantities and to observe their interactions. My project would model an a...

The paper describes how multiagent systems can be used to describe functionality of road traffic control systems. The introductory part contains a brief survey of actually available traffic models implemented in the hybrid compiler/interpreter NetLogo. These models have been studied and used for design of module-like sample codes. Consequently, they have served as basic building blocks when des...
