A Hybrid Indoor Positioning Technique for Order Picking and Warehouse Management

Abstract

With the trends of globalization and localization logistics plays a vital role in socio-economic development In addition to delivering goods efficiently corresponding companies must face the challenges resulting from the variety and complexity of indoor logistics in their warehouses Note that works in current warehouses are still relying on manual labor and most warehouse management systems are usually not fully computerized yet Consequently management tasks involving tracking goods personnel and vehicles are tedious and error-prone In this work we developed a WMS with positioning techniques to automatically identify and track our targets' current location According to features of different wireless positioning techniques UWB can achieve high accuracy high penetration and anti-interference so we attach UWB tags to handling personnel and vehicles In contrast RFID can achieve low cost low energy consumption and also it can use passive tags through these characteristics we attach RFID tags to goods Therefore for these components in the static or moving feature we use different positioning techniques Real-time location information can then be collected by sensors/anchors and immediately displayed to a warehouse manager for analytics and decision making As compared with a conventional warehouse management system the proposed system provides managers real-time location information and reduces the labor cost This system can be used to prevent accidents optimize equipment and labor utilization increase transportation efficiency track assets and accelerate inventory checks Furthermore recorded information can be employed in future work of automated warehouse management
