Work-in-progress (WIP) materials move through multiple stages before becoming finished products. When manufacturers cannot see where materials are located or how they move between workstations, production teams may spend time searching for items, experience delays, and struggle to identify bottlenecks. UWB Technology helps address these challenges by providing precise, real-time location information for tagged materials and production assets. When integrated with a WIP tracking system, it helps manufacturers gain better visibility into production flow and make informed operational decisions.
How UWB Technology Supports WIP Tracking?
Ultra-wideband (UWB) is a radio-based positioning technology designed for high-precision indoor tracking. In a manufacturing plant, UWB tags can be attached to selected materials, trolleys, bins, pallets, or semi-finished products.
Anchors or gateways receive signals from these tags, and the positioning system calculates their locations using methods such as Time of Flight (ToF) or Time Difference of Arrival (TDoA). This information helps teams identify where tagged WIP items are located across the production floor.
Unlike manual searches or periodic status updates, UWB Technology can provide location data that supports more timely tracking of materials as they move between production areas.
Improving Visibility Across Production Stages
A connected WIP tracking platform can use UWB location data to help teams monitor material movement across manufacturing stages. Operators and production managers can locate items on a digital floor map instead of relying entirely on manual checks.
This visibility can support several operational activities:
- Locate WIP materials: Find semi-finished products, pallets, bins, and trolleys more efficiently.
- Monitor production flow: Understand where materials are moving between workstations and process areas.
- Identify potential bottlenecks: Highlight items that remain in a designated area longer than expected when the platform is configured with suitable rules.
- Support traceability: Use location information alongside production records to improve visibility into material movement and process stages.
By connecting location information with production workflows, UWB Technology for WIP Tracking helps teams investigate delays, coordinate material handling, and make better-informed decisions about manufacturing flow.
Identifying Bottlenecks and Improving Production Flow
Production bottlenecks can occur when materials wait for the next operation, accumulate near a workstation, or become difficult to locate. Although location data alone cannot explain every cause of a delay, it gives production managers useful evidence for investigating these situations.
With UWB Technology, teams can use location information and configured dwell-time alerts to identify materials that have remained in particular zones beyond expected thresholds. Managers can then investigate whether the delay relates to workstation availability, material handling, scheduling, or another operational issue.
Location history and production-flow visualisations can also help teams understand recurring movement patterns. These insights support better coordination between workstations and help managers make informed decisions about material handling and production planning.
