About this write-up
This case study describes the engagement as recorded. The client is not named; figures and outcomes are as reported by the client and have not been independently audited.
The challenge
The textile group's weaving shed lost 22+ hours of productive loom capacity weekly due to uncoordinated warp beam replacements, yarn count changes, and style changeovers. Master schedulers managed 350 looms across static spreadsheets, leading to frequent weaver idle time and late buyer order shipments.
Objectives
- Connect weaving shed MES pick counters and warp beam tying records in real time.
- Sequence loom jobs by yarn count, reed width, and weft color compatibility to minimize setup downtime.
- Deliver automated beam staging and knotting work orders to floor technician tablets.
Discovery
Operational analysis showed that warp beam knotting crews experienced up to 4 hours of idle wait time waiting for yarn beams from spinning, while looms stood stopped awaiting knotting technicians.
What was built
- Picanol & Toyota Loom MES Data Bridges. Real-time telemetry ingestion of loom pick counters, stop causes, and active warp beam run-out timestamps.
- Combinatorial Finite Capacity Optimization Solver. Solves multi-constraint beam tying matrices, grouping compatible yarn counts and reed widths.
- Warp Beam Tying & Knotting Synchronization Engine. Synchronizes warp preparation in spinning with line-side loom beam run-out schedules.
- Weaving Shed Floor Dispatch Console. Delivers prioritized knotting tickets and beam staging alerts to technicians 2 hours in advance.
Outcomes as reported
Reported summary: +19% Loom Uptime Lift & 35% Faster Setups.
| Figure | What it refers to |
|---|---|
| 35% Faster Setups | Loom changeover and beam tying idle downtime reduced across 350 looms |
| +19% Uptime Lift | Recovered productive weaving machine capacity equivalent to 65 new looms |
| 97.6% OTIF Score | On-time-in-full buyer fabric deliveries achieved consistently |
| 15 Min Schedules | Daily schedule generation compressed from 4 hours of manual spreadsheet assembly |
Figures as reported in the engagement record; not independently audited.
Lessons
- Alerting beam knotting crews 2 hours prior to beam run-out eliminates over 80% of loom idle waiting time.
- Clustering similar yarn counts allows knotting machines to tie beams in place without re-threading heddles.
Next steps
Integrating downstream garment cutting schedules into the fabric weaving dispatch engine.
Implementation questions
Schedulers insert rush orders into the interactive Gantt console; the solver re-balances remaining loom queues in under 30 seconds.
