Laydown yard app with RFID
Hypothetical. Not a client, not a result.
// The problem
On a large mining or processing project, crews lose hours finding materials the materials system says were received, and surplus is only found at the end of the job.
// What we would build
A yard and site warehouse app on rugged Android devices that reads RFID and barcodes, works offline at the far end of the site, locates crates and large items by GPS, and keeps receiving, preservation and issue to construction in step with SmartPlant Materials and SAP through their APIs.
// What is in it
- Receiving against POs and packing lists, with heat numbers and MTR certificates attached to each item
- Laydown yard and warehouse locations by row and bay, found by RFID read, GPS or scan
- Preservation schedules and inspections, with reminders and photos
- Issue to construction against work packages, and surplus at close-out
- Offline on site, with an edge box per remote area that syncs when the link returns
- Integrates with SmartPlant Materials and SAP through their APIs; you supply the access
// Stack
