Productized Solutions

Our Products — software we built and run ourselves

Beyond custom projects, TW Engineering builds its own systems — from Local AI that runs inside the plant to WMS, ERP and OEE. Live in customer plants and ready to be tailored to your business.

01 / 07 Local AI In production

AI OMS

Local AI · Order-to-Production

AI reads the purchase order and dispatches work to every department

Drop in a PO as a photo or PDF. AI running on a server inside the plant reads the items and quantities, explodes the BOM, sends jobs to each department and produces the invoice and packing list — while production never sees a price.

AI OMS

Key features

  • AI reads POs from photos or PDFs — no keying
  • Confidence score per line; unsure lines go to a person
  • BOM explosion, with shared parts combined across POs
  • Each department sees only its own work
  • Assembly starts only when every part is ready
  • Production never sees prices — managers price via a single-use link
  • Invoice and packing list produced automatically
  • The AI runs inside the plant; data never leaves

AI Scheduler

AI · Production Planning

Production plans in seconds, with an AI that explains its reasoning

An engine builds the production schedule days ahead within every plant rule, then an AI co-pilot explains why the plan looks the way it does and helps with exceptions on the floor. Planner know-how becomes a system instead of leaving with people.
