The ChiAha tool family

The engines behind our consulting work are also products, each built for one kind of problem. Most have a free sandbox you can try in the browser, and each has its own site with demos, pricing and docs.

AI Agent Sandbox
Validated Production Models

Discrete rate simulation validated within 1% OEE. Find improvements your loss tree will never surface. AI agent grounded in your scenario.

AI Agent Sandbox
SCModeling
Design. Optimize. Simulate. Prove.

Sketch a supply chain on the canvas, drop optimization on it (AMOS / SCG), run discrete-event simulation against the result. 10 demos against real sample data, with engine output visible inline.

AI Agent Sandbox · Free
QueueSim
M/M/c Queueing Simulator

Run any of four preset scenarios (single server, coffee shop, grocery checkout, call center), watch the queue form, and ask the on-page agent to interpret the result. Pairs with the public MCP for use inside Claude.

AI Agent Sandbox
Distribution Fitting

8 distribution types, Quick Start solver, interrupt designer. Turn historian data into simulation-ready parameters. AI agent for theory + interpretation.

AI Agent Sandbox
QSimHealth
ED staffing decisions, modeled before you commit.

Run your emergency department's numbers, compare staffing scenarios, see the wait-time and cost tradeoff. Developed in conjunction with the University of Tennessee Physician Executive MBA program.

Live Sandbox · Free
Decoupling
Simulator
Custom Web App

Simulate decoupling strategies for flaked product lines in seconds, not months. Test off-ramp dryers, tote storage, and on-ramp reconstitution modules against real production data — validate improvement ideas before you implement.

Industrial IoT
Adaptive Edge
Edge Data Acquisition

Drop a $500 box on the plant floor, plug in Ethernet to the PLC, power on. Time-series data with dashboards — no cloud, no IT department.

DiscreteRate
Discrete Rate Simulation Paradigm

Three demos (Fast-Slow Drain, Hamburger Duo, Valdez Tanker) of the rate-based paradigm Andrew Siprelle invented in 1990. Teaching agent quotes engine output verbatim. Companion textbook in progress.

Run the tools inside Claude, ChatGPT or Cursor

Six of the tools are also public Model Context Protocol servers, listed in the official MCP registry. Ask a staffing, OEE or queueing question and the assistant calls the real simulation engine, then answers with its numbers. The public servers need no login or API key.

Rather have us run the model?

We use these same engines on client engagements. If you'd rather hand us the question than learn a tool, we can build and run the model for you.
