# Wrysto Enterprise Technical Knowledge Base (LLMs Full)

## 1. System Overview & Architectural Philosophy
Wrysto bridges the gap between high-level corporate ERP systems (SAP, Oracle, Microsoft Dynamics) and physical shop-floor maintenance reality.
In most manufacturing plants, maintenance records are fragmented across paper logbooks, whiteboard schedules, Excel sheets, and messaging groups. This causes three critical vulnerabilities:
1. **Unplanned Downtime**: Lubrication, belt tensioning, and bearing inspections are skipped because calendar reminders live in disconnected spreadsheets.
2. **Ghost Inventory & Stockouts**: A critical pump breaks down, but the emergency mechanical seal listed as "in stock" on the ERP is physically missing or has been consumed without record.
3. **Audit Failure & Safety Hazards**: Lockout/Tagout (LOTO) and permit-to-work isolations rely on verbal handovers, creating life-threatening risks during shift changes.

Wrysto solves this through a closed-loop digital maintenance operating model:
Asset Registry -> PM Scheduling -> Work Order Dispatch -> Spare Parts Deduction -> Safety Clearance -> Shift Handover -> Executive Reliability Analytics.

## 2. Core Functional Modules

### 2.1 Asset Intelligence & Equipment Hierarchy (ISO 14224)
- **Standardized 5-Level Hierarchy**:
  1. Plant / Site (e.g., Ashuganj Power Station)
  2. Area / Department (e.g., Boiler Island #2)
  3. System (e.g., High-Pressure Feedwater System)
  4. Equipment / Machine (e.g., Multi-Stage Boiler Feed Pump BFP-01)
  5. Component / Wear Part (e.g., Mechanical Seal DE, Deep Groove Ball Bearing 6312)
- **Dynamic Waterproof QR Tagging**:
  Technicians scan QR codes attached to physical machinery to immediately display:
  - Equipment technical specifications (KW rating, RPM, operating pressure).
  - OEM wiring schematics, P&IDs, and maintenance manual PDFs.
  - Full lifetime fault log and repair cost history.
  - Pending PM routines and active breakdown tickets.

### 2.2 Dual-Trigger Preventive Maintenance (PM) Engine
- **Calendar-Based Triggers**: Daily, weekly, bi-weekly, monthly, quarterly, semi-annual, and annual rhythms.
- **Running-Hours Meter Triggers**: Integrates with running-hour meters (e.g., every 250 operating hours for oil replacement, 1,000 hours for valve overhauls).
- **Dual Trigger ("Whichever First")**: Dispatches work order upon reaching either the calendar due date OR the running-hours threshold.
- **Mandatory Digital Checklist Procedures**:
  - Enforces mandatory sensor reading inputs (temperature °C, vibration mm/s, motor current Amps).
  - Out-of-tolerance inputs trigger automated secondary inspection warnings.
  - Photo attachment requirement for completed work verification.

### 2.3 Work Order Lifecycle & Shop-Floor Execution
- **Operator Mobile Defect Reporting**: Shift operators scan QR tags and submit tickets with photos and priority classification (Critical, High, Medium, Low) in under 15 seconds.
- **Maintenance Supervisor Dispatch Board**: Drag-and-drop assignment to shift technicians, skill tagging (Mechanical, Electrical, Instrumentation), and SLA countdowns.
- **Technician Mobile Queue**: Step-by-step job instructions, required spare parts list, and one-tap timer for wrench-time logging.
- **Digital Shift Handover Log**: Summarizes active breakdowns, closed work orders, and utility parameters into audit-ready shift handover reports.

### 2.4 Spare Parts Store & Inventory Synchronization
- **Work Order Parts Allocation**: Technicians reserve parts directly from the work order. Spares are deducted automatically upon work order closure.
- **Multi-Location Warehouse Bin Tracking**: Tracks parts by Warehouse -> Aisle -> Shelf -> Bin.
- **Automated Low-Stock Re-order Alerts**: Email, SMS, and WhatsApp alerts to store managers when stock falls below safety buffer levels.
- **Min/Max Reorder Quantity Calculation**: Based on historical lead times and monthly consumption rates.

### 2.5 Safety, Lockout/Tagout (LOTO) & Permit to Work (PTW)
- **Digital Isolation Checklists**: Electrical breaker racking, valve blanking, pressure depressurization, and residual energy dissipation.
- **Supervisor Digital Signature**: Work orders locked until the safety officer verifies physical padlock attachment.
- **De-isolation Verification**: Mandatory post-repair clearance steps before machine re-energization.

### 2.6 Executive Reliability & KPI Analytics
- **MTBF (Mean Time Between Failures)**: Tracks average operating hours between machine trips.
- **MTTR (Mean Time To Repair)**: Measures average technician response and repair duration.
- **PM Schedule Compliance Rate**: Percentage of preventive work orders completed within tolerance windows.
- **Downtime Cost Analytics**: Real-time calculation of financial production losses per machine line.

- **Cement, Clinker & Mineral Processing**: Rotary kilns, raw mills, ball mills, clinker coolers, and baghouse filtration systems.
- **Steel, Re-Rolling & Foundry**: Electric arc furnaces, induction furnaces, continuous casting machines, and rolling mill drives.
- **Chemicals, Fertilizers & Pharmaceuticals**: Reactors, distillation columns, Clean-in-Place (CIP) systems, and HVAC cleanrooms.
- **Food & Beverage Processing**: Homogenizers, pasteurizers, filling carousels, cold storage ammonia compressors.
