📋 Case Study

Open Pit Iron Ore Mine Fleet Harmonization at Rio Tinto Pilbara

Heterogeneous OEM protocols causing dispatch system latency >12s and payload mismatch errors

🏗️ Project Overview

Integration of Komatsu 930E AHS with legacy Hitachi EH4000 trucks via third-party middleware

🎯 Challenge

Heterogeneous OEM protocols causing dispatch system latency >12s and payload mismatch errors

🔧 Design Approach

Deployment of ISO 15066-compliant OPC UA translation gateway with real-time payload normalization engine

📐 Key Calculations

Payload Normalization Error

ABS(declared − measured)/measured × 100

Result: 0.8%

Within MSHA ±1.5% tolerance

Dispatch Latency Reduction

Legacy − New

Result: 9.3 s

Enables dynamic re-routing within 3s of pit condition change

📊 Results

Dispatch latency reduced from 12.7s to 3.4s; payload reconciliation improved from 82% to 99.6%; fuel consumption down 7.2%

💡 Lessons Learned

• •Middleware must support bi-directional payload telemetry and fault injection testing
• •OEM firmware version alignment is mandatory pre-integration
