Client Background

A packaging & printing manufacturer generating 300M+ RMB annually, serving FMCG and electronics clients across 2,000+ SKUs. Frequent rush orders and scheduling expertise concentrated in just 2 senior planners created critical dependency risk.

Core Challenges

Scheduling depended on people: 30-40% error rates when planners were absent, directly impacting delivery commitments. Cost estimates by gut feel: Pricing relied on instinct, leading to either lost bids or margin erosion. Quality drift caught too late: Deviations went undetected until hundreds of units were produced — losses were already baked in.

Labor-Time Prediction Model: Data-Driven Scheduling

A private labor-time prediction model trained on 14 months of historical work orders, replacing planners' experience-based estimates.

  • Integrated ERP work order records, equipment logs, and shift schedules into a standardized training set
  • Model predicts using 15+ features including order complexity, equipment status, and operator skill levels
  • Delivered as a FastAPI endpoint seamlessly embedded into existing planning workflows
  • Models retrained automatically every month using the latest 3 months of data
On-premise deployment: the model runs on the client's own servers, data never leaves the factory

Real-Time Quality Alerts: Catch Issues Early

Predictive quality monitoring based on historical defect data, with real-time anomaly detection during production.

  • Connected incoming inspection, in-process checks, and finished goods QC data streams
  • Automatic alerts triggered when anomaly trends breach thresholds, preventing batch defects
  • Incoming defect rate dropped 42% from baseline, reducing rework and scrap

Smart Cost Estimation: Confident Pricing on Every Bid

Labor-time predictions fused with material costs, equipment depreciation, and energy data for order-level cost precision.

  • SKU-level cost baseline built from historical actual costs across all past orders
  • New orders generate cost ranges within 10 seconds, empowering sales to price confidently
  • Eliminated guesswork — reducing both lost bids and unprofitable orders

Implementation Roadmap

Phase 1 · Data Foundation1-2 months
  • Historical work order data cleansing and standardization
  • Establish baselines for labor, quality, and cost data
Data quality validated, model training sets ready
Phase 2 · Model Deployment2-4 months
  • Labor-time prediction model training and validation
  • FastAPI endpoint integration with planning tool
  • Quality anomaly alerting module deployment
Planning time cut 50%, on-time delivery reaches 90%+
Phase 3 · Continuous Optimization4-6 months
  • Smart cost estimation module launch
  • Automated model retraining pipeline
  • Factory-wide OEE improvement program
Incoming defects down 42%, OEE up 8%

Scenario: Rush Orders Without Panic

Pain point

A client suddenly added 5,000 custom gift box orders with a 7-day deadline. Previously, planners would guess at scheduling, often causing other orders to slip.

Approach

The model evaluated current line load, material inventory, and equipment status — producing an optimized schedule in 10 seconds that balanced the rush order against existing commitments.

Result

Delivered on time in 7 days with zero impact on other orders. The factory reduced dependency on key individuals and lifted OEE by cutting changeover wait time.

How We Cut a Packaging Plant's Planning Time by 50% with a Custom AI Model

A 300M RMB/year packaging manufacturer was running its entire schedule from two planners' heads. We built a private AI model on their historical work orders and cut planning time in half while lifting on-time delivery from 78% to 94%.
