Abstract

The dynamic real-time management system comprises a micro-processor adapted to sense real-time inputs related to the condition of a powered system. Manual inputs are provided to the word processor and a long-term memory is included. The memory stores historical data related to the real-time inputs and the micro-processor compares sensed real-time parameters with historical data to determine changes in certain unknown operating parameters. The information generated in the micro-processor is transmitted to a central micro-processor contained in a central management facility. In this manner, managers have direct access to information generated at one or more powered systems in order to enable them to make reasonable, logical management decisions to cure costly inefficiencies quickly and reliably.
