A method is provided for dynamically tracking a plurality of entities progressing through an operation each having an electronic tagging device associated therewith. The method includes sensing signals emitted by each of the plurality of tagging devices, at predetermined instances or when triggered by external events, by a plurality of sensors located at predetermined sites with respect to the operation, each signal including information uniquely identifying the corresponding tagging device, communicating the sensed signals and corresponding energy levels at which they were sensed by each of the plurality of sensors to a data processor, processing the unique identification information provided by the signals and their energy levels to determine a location of each tagging device relatively to the predetermined sites of the sensors, and dynamically updating a path of each tagging device and the associated entity based on the determined location with respect to at least a portion of a displayed map of the operation.
