Getting started

Microstat is a suite of simulation and analysis tools for small businesses. It includes three tools:

  • Process Map — model a workflow as a network of nodes, run discrete-event simulations, and identify bottlenecks.
  • Spreadsheet Sim — take an existing Excel workbook, mark uncertain inputs as probability distributions, and run a Monte Carlo simulation over your model.
  • Probability Playground — write a quick back-of-the-envelope model in a mini-language and instantly see the output distribution as a histogram.

Quick start​

Process Map​

  1. Sign in and go to App → Process Map.
  2. Press S to place a Start node, T for Task nodes, E for an End node.
  3. Use the Connect tool (C) to draw edges between nodes.
  4. Click the simulation icon on any node to set service time distributions.
  5. Press Run in the header to launch a simulation.

Spreadsheet Sim​

  1. Sign in with a Pro account and go to App → Spreadsheet Sim.
  2. Click Upload .xlsx and choose your workbook.
  3. In the sidebar, click + Add under Assumptions to mark uncertain cells.
  4. Click + Add under Outputs to select result cells.
  5. Set the rep count and click Run.

Probability Playground​

  1. Go to microstat.app/app/playground/ — no account needed.
  2. Type a model in the editor, e.g. revenue ~ norm(50000, 10000); costs ~ norm(30000, 5000); profit = revenue - costs;
  3. The histogram updates instantly.

API access​

All tools expose a REST API under /api/. Authenticate with a session cookie or an API key Bearer token. See the API spec for endpoint details.
