Thirty-five years building decision applications for 300+ companies including many Fortune 500 operators — Essity, Kellogg’s, Symbotic, JTEKT, Process Plus, Teleflex, Estée Lauder, Process Partners, and others. See the proof.
Explore the efficient frontier for your problem
Precision tools at the intersection of AI and operations research — turning uncertainty into strategy, and complexity into clarity.
Discrete rate simulation validated within 1% OEE. Find improvements your loss tree will never surface. AI agent grounded in your scenario.
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.
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.
8 distribution types, Quick Start solver, interrupt designer. Turn historian data into simulation-ready parameters. AI agent for theory + interpretation.
Data-driven supply chain insights in minutes, not months. Optimal facility locations using advanced analytics and GIS — without the consulting price tag.
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.
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.
Dynamic mass-energy balance for thermal processing. Expert coaching to operators in real-time. 13% energy reduction, 0 safety incidents.
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.
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.
Every ChiAha tool is also a public Model Context Protocol server, registered in the official directory. Ask Claude a staffing question, an OEE question, a queue question — it calls the real simulation engine and answers with verbatim numbers. No login, no API key on the public surface; you pay the LLM provider through your own account.

Every tool is grounded in mathematical foundations — queuing theory and reliability statistics. No black boxes.
AI reads the loss tree and points at the Labeler. Simulation reveals the real story: 120 one-minute micro-stops on the Filler cascading through the line. Every ChiAha tool ships with a chat agent and a public MCP — the analytics are now reachable from your AI conversation, not just our app. See how →
Generic tools make generic decisions. ChiAha tools are built for specific domains — healthcare, reliability, thermal processing — with full context.
Every simulation, every model, every output is designed to produce one thing: a decision you can act on with confidence.
"We leveraged the model to recommend solutions that saved $21.7M in inventory carrying costs and reduced transit time by 19%."
"Instead of taking a snapshot, this is more like a video. Your ability to actually see the activity in action while the supply chain is running lets you understand impacts much better."
"The team went above and beyond the project scope, proactively brainstorming ways to make our project better."
ChiAha provides services supporting teams in adopting a proven, scientific approach for faster, better operational decisions. Using your data, our simulation techniques draw from 35 years of manufacturing modeling expertise.
Capacity modeling, bottleneck identification, and what-if analysis.
Practical application of constraint theory and lean principles.
Leverage production data historians for accurate predictions.
Convert production questions into data-driven decisions.
Model-based configuration testing and risk assessment.
Next-generation simulation for intuitive OEE improvement.
ChiAha was created with consulting partners from Technology Optimization & Management, representing 35 years of intensive model-building for diverse industries.
Educator, consultant, and simulation tool developer. Creator of Discrete Rate Simulation (1990). Most advanced analytics never reach the people who need them.
