1. A system for distributing warnings regarding an event, the system comprising:
a policy specification subsystem for generating one or more machine readable policies, each policy comprising at least one rule and at least one action associated with the at least one rule, wherein each rule includes a plurality of event parameters and an associated plurality of predetermined event parameter probabilities; a change detection subsystem for receiving and monitoring data from a sensor system, the data including expected event parameter values and associated deviation metrics; a policy execution subsystem for executing the at least one rule and triggering the at least one action based on a comparison of the expected event parameter values and associated deviation metrics with the event parameters and the associated predetermined event parameter probabilities of the at least one rule, wherein the policy execution subsystem initiates processing of the at least one rule after receiving instructions from the change detection subsystem, wherein the change detection subsystem sends instructions to the policy execution subsystem upon detection of a predetermined change in at least one of the expected event parameter values; and an action processing subsystem for generating an output for performing the at least one action triggered by the policy execution subsystem.
