Viskit is an open-source application to build Discrete Event Simulation (DES) models that autogenerate Java source for simulation using the Simkit library.
The Viskit application enables authors to assemble a collection of event graphs that describe the behavior of multiple entities in a simulation environment.
Capabilities include Simkit Event Graphs, Assemblies, Run Simulation replication tools, and an Analyst Report generator suitable for thesis and research efforts. Further details are found in the
The 2025 software release is a thorough refactoring of the underlying Viskit source code, facilitating ongoing project maintenance and development.
Expected to return in future distributions: Diskit, which is a Java package of Distributed Interactive Simulation (DIS) utilities and Simkit entities for 3D movement support. The opendis7-java library is used for state-distribution capabilities that integrates the Distributed Interactive Simulation (DIS) protocol for networked agent behaviors and Live Virtual Constructive (LVC) simulations.
We currently use Apache NetBeans to run and develop Viskit. We are planning on releasing binary executables starting in summer 2025.
Software and model development efforts are ongoing. The viskit wiki provides an overview presentation video and slideset.
