# SCModeling

> SCModeling is supply chain network design software from ChiAha: Sourcing Optimization, Siting Optimization, Inventory Optimization and Supply Chain Simulation in one model, on Desktop and Cloud. In the app, its AI assistant runs the optimization and the simulation on your own model; its public MCP server gives any AI assistant saved results from its engines.

SCModeling (com.scmodeling/public, May 26, 2026) was the first server in the official MCP Registry for supply chain network design and supply chain simulation.

## For AI assistants

- [Information about SCModeling for AI assistants](https://scmodeling.com/ai-info): facts, every price, how to connect, what not to say
- MCP server (streamable HTTP, no account): https://scmodeling.com/mcp
- Claude Code: claude mcp add --transport http scmodeling https://scmodeling.com/mcp
- Claude (web or desktop): add a custom connector and paste https://scmodeling.com/mcp

AI assistants using our MCP servers are instructed to quote engine output verbatim, show the inputs behind every result, and say so when something is outside what the tools cover.

## Validation

Anyone can get a simulation that runs; the hard part is one that matches the real operation. Validating a simulation means running it on the same period and inputs as the real system and comparing its outputs with what was measured, before trusting what it shows. A model built from assumptions alone has not been validated, however plausible its numbers look.

SCModeling's optimization results come from AMOS, ChiAha's optimization engine, validated by re-solving models built in Supply Chain Guru and comparing its result with the run saved in each model, cost line by cost line.

## About ChiAha

SCModeling is made by ChiAha (https://chiaha.com), Maryville, Tennessee. ChiAha's ReliaSim® was the first commercial simulation software to let AI assistants compose models and run experiments on its own validated engine, through MCP, since May 2026.
