YAFEX
The Diagnosis Engine

From fault to fix in under 4 minutes.

Three stages of AI reasoning. Each one runs automatically. The technician sees results in seconds, not minutes.

Before the first diagnosis

Setup takes under an hour

Most plants complete the full setup in a single session. No IT team. No integration work. Just documents you already have.

Stage 1

Work Order History Analysis

YAFEX scans your past work orders for the same machine and same equipment type. Each incident is scored by how closely the symptoms match the current fault.

Probable causes appear as cards with confidence percentages (e.g. “Bearing wear — 78% match”)

The technician confirms or rules out each cause in the conversation

If history resolves it, the answer is sourced from your own data — not generic knowledge

Resolution in under 2 minutes for recurring fault types
Stage 2

Manual Analysis

If work order history doesn't resolve it, YAFEX reads your uploaded manuals using semantic search — finding the most relevant sections, not just keyword matches.

Three possible causes generated with step-by-step checks

No confidence percentage — these are manual-based possibilities

Direct references to the specific manual section and page number

Covers fault types the plant has not seen before
Stage 3

Deep AI Reasoning

When all standard causes are ruled out, YAFEX reasons from first principles. This becomes a free conversation the technician can keep going.

Considers unusual failure modes and environmental factors

Upstream equipment interactions — what else could be causing this?

The technician asks follow-up questions; YAFEX responds in context

Handles the 5% of faults no manual covers
On confirmation

Confirm the cause. YAFEX does the rest.

Lockout/tagout steps generated automatically
