CASE STUDY — CJ Logistics
CJ Logistics raises maritime arrival prediction accuracy from 40% to 85%.

Challenge
Maritime transport exposes shippers to weather, routing, GPS-coverage, and voyage-distance uncertainty; before Cargo Tracking, arrival prediction accuracy stood at 40%. That uncertainty forces inventory buffers when late arrivals can disrupt production or fulfillment. Repetitive manual work also persists across warehouse, transport, parcel, forwarding, and overseas operations, while online sellers face slow system links with logistics providers. New packaging rules add another process burden as operators judge over-packaging exceptions, merged parcels, and reusable materials.
AX Intervention
CJ Logistics' TES Logistics Technology Institute builds AI Cargo Tracking to analyze voyage information, route, weather, GPS-signal availability, and vessel distance for arrival prediction. It deploys RPA software robots across operations to absorb repetitive manual tasks. e-FLEXs automates online seller-logistics integration and uses AI and big data to forecast order patterns for fulfillment labor planning. TES also productizes PackCheck for AI-based over-packaging diagnosis and extends computer-vision robotics, including depalletizer arms and humanoid packaging trials.
Outcome
Cargo Tracking raises maritime cargo arrival prediction accuracy from 40% to 85%. CJ Logistics states that lowering safety stock by 30~40% versus before through improved arrival prediction makes it possible to expect lower storage-related logistics costs, manufacturing schedule planning, and prevention of overproduction.
RPA saves 5,600 hours, with about approx. 30K hours additional hours expected. System integration time between online shopping malls and the logistics provider falls to 1/10. AsiaToday reports that CJ Logistics has deployed PackCheck across 26 centers logistics centers nationwide, and NLIC reports that its vision AI depalletizer processes 700 boxes per hour while lifting boxes up to 20 kg.

Applicability
- Tie ETA prediction pilots to inventory policy, not only visibility; test whether lower buffers can be measured without service risk.
- Start with RPA in documentation, settlement, booking, and status-update workflows before committing field-automation capital.
- Turn seller integration and compliance checks into customer-facing logistics services for Korean exporters and direct-to-consumer brands.
