Claim 8:
9. A method of monitoring and controlling an environment using a network of sensors and actuators operating in accordance with predetermined policies, wherein effectiveness of individual policies is monitored by comparing inputs from the sensors with intended outcomes from policies controlled by previous inputs from one or more of the same sensors, in which each policy includes a check action for assessing the result of that policy's application, wherein a sensor monitors actions generated by the policy and generates an output indicative of whether a system state is approaching a condition specified by the policy, and actions generated by the policy are initiated in response to inputs from one or more first sensors, and the check action is initiated in response to data from at least one further sensor independent of the one or more first sensors, and in which a quality ranking of the policy is generated based on the effectiveness of its action in moving the system towards a system state specified by the policy.
