Real-Time Locating System is the foundation for Real-Time Asset Visibility and a Necessity for Better Asset Utilization or “On-Demand” Real-Time Personnel Visibility for Personnel Safety







The key to effective asset tracking and supply chain management is having real-time visibility. Some real time locating asset management system implementations have yielded return of investment (ROI) in less than a year.

REAL-TIME LOCATING PROVIDES ASSETS VISIBILITY

Problem Addressed

Benefits

1.      What are the assets within the monitoring area?  (“Who-What”)

§          Real-time inventory

§          Visibility of assets

§          Better supply chain management and cost savings

2.      Where are the assets? (“Where”)

§          Facilitate asset utilization

3.      What are the conditions or events that happened to each asset?  (“What-When”)

§          Visibility of utilization of assets

§          Visibility of the assets movement and utilization

§          Facilitate servicing and maintenance


In the case of supply chain management, real time visibility can dramatically enhance supply chain security and may help to save most of the current 6-10% loss encountered by the industry. For most supply chain management applications, real-time visibility to the last control access point or choke point may be adequate. Passive barcode or passive RFID tags, at lower price per tag or label, is cost effective.
