Our WebApps eliminate the most time-consuming and error-prone steps in operational modelling — so you spend less time fixing problems and more time solving your client's.
Our WebApps take the pain out of the more challenging elements of developing operational models to give you a faster, more accurate results.
We follow industry best practice methods with auditable transparent steps allowing less experienced modellers to meet NSW modelling guidelines calibration and validation criteria repeatedly on time.
Achieve operational realism AND budget realism.
Our WebApps are designed to be run without requiring extensive access to your company systems or by downloading any active files that may pose a security risk. We provide the tools for you to get the job done quickly, confidently and on the fly so you can get on with solving more of your clients’ problems.
No IT approvals. No complex setup. No downloads. Just open a browser and start working.
Built for Modellers, Engineers and Project Teams.
Designed for professionals working within real project constraints — where speed, accuracy and consistency directly impact delivery.
Smart, Scalable & Industry-Ready Platforms.
Purpose-built for operational modelling. Ready when you are.
Numerous tools. One workflow. Built specifically for operational microsimulation — from signal coding to matrix calibration to stakeholder sign-off.
Each tool addresses a specific pain point in the operational modelling workflow — and they work better together. Start with one. Add more as your projects demand.
Purpose-Built Applications for Real-World Impact.
Built From Real-World Challenges
Every RDTI application begins with a recurring project challenge, is refined through practical delivery and returns to industry as a smarter, more repeatable workflow.
RDTI tools are developed from real operational modelling workflows, tested through practical use and designed to make complex project tasks more repeatable, auditable and reviewable.
VAPiT
- Signal realism, delivered in minutes—not weeks
- Less coding, more confidence, faster approvals
- From idea to tested signal plan—without the drag
Signal Monitor
- Spot drift early. Fix it before it costs
- Know what changed—and why—at a glance
- Keep signal assumptions honest, project after project
- PDF-ready outputs for submission and audit trail
StickFigure
