F3: Factory Readiness & Gap Analysis Engine

Overview

F3 is the core quantitative assessment module of the platform. Rather than merely stating which standard applies, F3 evaluates whether a manufacturer is legally ready to pass a statutory factory inspection. It parses verified compliance artifacts against two distinct statutory regulatory regimes:

1. BIS Scheme-I (ISI Mark Certification) under the Bureau of Indian Standards Act, 2016.
2. Automotive AIS Homologation under Central Motor Vehicles Rules (CMVR), Rule 126 / AIS-037.

Say It Out Loud

I built the Factory Readiness Gap Engine so that factories don't just find out which standard applies, but know exactly whether they can pass a surprise government audit tomorrow morning.

In gap_engine.py, the evaluate_readiness function dynamically detects whether the identified standard belongs to Bureau of Indian Standards Scheme-I or Automotive Industry Standards Homologation. If the standard contains the letters 'AIS', it activates our automotive checklist; otherwise, it defaults to the BIS Scheme-I checklist. It then matches the factory's verified artifacts against weighted criteria totaling one hundred percent. For example, under BIS Scheme-I, having clause-specific in-house test benches carries twenty-five percent weight, while valid NABL calibration certificates carry fifteen percent. If any mandatory item marked critical is missing, the engine automatically flags a critical deficit and drops the status to Non-Compliant, even if the factory has a passing numerical score.

I selected a transparent, deterministic rule-based scoring engine instead of an LLM because compliance calculations must be completely mathematically reproducible and auditable in legal proceedings.

When evaluated, the engine returns an exact percentage, a list of specific missing items, and the exact remediation action, which renders live on the React frontend. One limitation is that currently documents are verified via checkbox selection; in future releases, we plan to parse uploaded PDF certificates using optical character recognition to verify NABL accreditation numbers automatically.
