How do I simulate a delivery route?

Open this page and use the live Critical Path (CPM) tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a delivery route from your own measurements.

Task D duration (days)

The Critical Path Method finds the longest chain of dependent tasks through a project — the sequence that sets the minimum completion time. Tasks on it have zero slack: delay any one and the whole project slips. Tasks off it can float. Stretch task B or D and watch the critical path re-route. The backbone of project management.

Reading this result: The critical path is A → B → D → F at 15 days. Tasks C, E carry slack — delaying them will not move the finish date, but any slip on a critical task pushes the whole project.

Governing equation

T = paths max i \sum d_{i} = 15 days, slack_{i} = L S_{i} - E S_{i}

About this simulation

The full Critical Path (CPM) tool models a delivery route with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
