Explore the efficient frontier for your problem
Simulation, reliability statistics and AI agents for production lines and supply chains.
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.
Candidate facility locations from your own customer and demand data, in minutes, not months.
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 built on queuing theory and reliability statistics, and the methods are published.
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 reachable from your AI conversation as well as our apps. See how →
Each tool is built for one kind of problem, such as reliability on high-speed lines, patient flow in clinics or thermal processing, and starts from that field’s own data and terms.
A model begins with a question someone has to answer, such as which failure mode to fix first, how big a buffer should be, or where a distribution center should go.
"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."
Peer-reviewed and conference work published by the Simulation Dynamics and ChiAha team.
Independent trade press and talks covering our work.
Peer-reviewed papers written by customers and partners about work carried out with our tools. Authored by them, not by us.
Discrete-rate and mesoscopic simulation work by researchers outside our team, listed because it builds on, compares against, or extends the methods above.
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.
Check the model against your historian data before trusting its predictions.
Convert production questions into data-driven decisions.
Model-based configuration testing and risk assessment.
Models line flow as rates that change when machines stop and start, so a year of production runs in under a second.
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. Thirty-five years spent making AI, operations research, and high-power computing actually improve systems — not just fill white papers. ChiAha puts those tools in your hand.
Product lead across the ChiAha tool family. Shapes the sales, marketing, and user experience surface for ReliaSim, ReliaStats, DiscreteRate, and the broader ChiAha product suite.
