A system and method of de-duplicating data using a graphical user interface application. The indoor localization method includes forming signal vectors from the localization signals received by the radio badge at each of predetermined locations in the indoor space, and generating a signal ID value from the signal vectors for each beacon from which the radio badge has received the localization signals. The simulator includes an evaluation engine that determines the amount of resource used during each simulation interval of the simulation and records the resource usage in a resource contention timeline, which can be displayed to a user.
