1. A method of modeling a service using a Bayesian network and status information in a distributed environment, the method comprising the operations of: creating, by a computer system, a scenario to specify at least one service; categorizing, by the computer system, the service into models according to properties based on the scenario; setting, by the computer system, interrelationships including a chronological relationship, a hierarchical relationship, and correlation between the categorized models; and deriving, by the computer system from the scenario, information including a service goal and status information; deriving, by the computer system, intermediate goals from the service goal, wherein the intermediate goals are not stated in the scenario; deriving, by the computer system, specific goals from a combination of the status information; and linking, by the computer system, the intermediate goals with the specific goals to complete service modeling.
