Comparison study of Janus and JLINK

Abstract

The Janus simulation model was initially designed to operate in a stand-alone mode. There is an ongoing research project to link Janus to other constructive simulations and virtual simulators. The present standard used to connect different models is Distributed Interactive Simulation (DIS). Janus can operate in a DIS environment using a cell adapter unit called the World Modeler. The combination of Janus and the World Modeler is known as JLink. A goal of the JLink system is to replicate the analytical and training fidelity of stand-alone Janus in a distributed exercise. The purpose of this thesis is to assess the current state of JLink development. The experiment simulated three scenarios: armored, armored coalition, and light infantry battalions attacking against a defending company. All scenarios were executed in two contrasting environments. The simulation included the recently developed JLink features Family of Scatterable Mine (FASCAM) and chemical artillery. The thesis used five Measures of Performance to base the assessment: (1) FASCAM kills, (2) Chemical Artillery Kills, (3) Detection Ranges, (4) Kill Ranges, and (5) Loss Exchange Ratio. The statistical tests used for analysis were the Analysis of Variance (ANOVA) test, two-sample t-test, and Wilcoxon test. The results of the analysis show that JLink requires adjustments to artillery delivery methods in order to correct chemical artillery discrepancies and detection range issues. In general, JLink accurately portrays coalition warfare and satisfactorily replicates armored and infantry scenarios in contrasting environments
