1. The Problem: The Hidden Cost of Batch Purity Fluctuation
In batch chemical manufacturing, raw materials do not arrive at uniform 100% assay purity. For this Ankleshwar-based specialty polymer unit, active ingredient concentration across incoming ISO tanks and steel drums varied from 88.4% to 96.1% depending on supplier lot and moisture absorption.
Under their legacy operating model, the plant used static Standard Bills of Materials (BOM) managed on spreadsheets. The shop-floor compounding operators weighed fixed kilograms of raw active ingredients regardless of the lot's actual assay certificate.
| Operational Gate | Legacy Chaos (Before) | Arihant AI Process MRP (After) |
|---|---|---|
| Assay Purity Adjustment | Fixed recipe weights on floor. Low-assay lots caused viscous failure; high-assay lots wasted costly monomer. | Dynamic algorithmic compensation: Odoo auto-calculates exact active vs carrier weights upon lot selection. |
| Warehouse Quarantine | Physical chalk marks on drums. Night-shift operators consumed unapproved lots before QA lab sign-off. | Hardware barcode lockdown: Odoo blocks picking slips from moving any lot currently in WH/Quarantine. |
| COA Generation | Lab assistants spent 35 minutes re-typing test values into Microsoft Word. Consignments delayed at weighbridge. | 1-Click tamper-proof COA with cryptographic QR verification generated automatically upon invoice creation. |
| Regulatory Audits | Paper BMR binders prone to coffee stains, missing signatures, and non-compliance warnings. | Complete electronic audit trail with digital timestamps and dual-operator verification under Schedule M. |
2. The Engineering Architecture Deployed
To permanently stop batch rejection without adding administrative burden on operators, Arihant AI engineered a 3-layer industrial process MRP suite integrated directly into Odoo 19 Enterprise:
Odoo 19 Chemical Process Architecture
When an operator scans a raw material lot number into a Manufacturing Order, Odoo fetches the QA-approved assay percentage. If the standard recipe requires 100 kg of 100% active substance, and Lot #CH-904 contains 92% purity, the engine automatically adjusts the required charge to 108.70 kg while proportionally reducing the neutral solvent buffer.
Incoming goods receipt notes (GRN) automatically deposit inventory into a restricted virtual location (WH/Quarantine). The system algorithmically denies any transfer, reservation, or manufacturing consumption until the analytical laboratory inputs pH, viscosity, and assay results and clicks "Release Lot".
Upon passing in-process and finished goods QC inspection, Odoo merges the batch lab metrics directly into a formatted Certificate of Analysis. The document contains an encrypted verification QR code for institutional customers, instantly linked to the e-Way bill and invoice without manual human intervention.
3. The Results: 18.4 Lakhs Saved and Zero Customer Rejections
Within six months of go-live across all six reactor lines, the plant recorded dramatic operational improvements:
- Batch Rework Dropped to 0.6%: Out of 840 batches produced, only 5 required minor solvent trimming, down from an average of 62 failed batches under the legacy system.
- Elimination of Active Monomer Overdosing: By calculating exact potency down to the decigram, the plant eliminated the previous "safety margin" of adding 2% excess active monomer, saving ₹18,42,000 in raw material expenses annually.
- Logistics Turnaround Accelerated: Tanker dwell time on the weighbridge decreased from 4 hours to 45 minutes because shipping documents, COAs, and GST e-Way bills were ready the moment final QC approved the batch.
"Before Arihant AI, our shift supervisors spent half their night arguing with QC over why a reactor batch failed viscosity specs. Now, the system calculates exact potency compensation before the valve ever opens. Our rework rate dropped to near zero, and we passed our multinational client audit on the first inspection."
