A new evaluating pattern for simulation system

Dynamic behaviors of simulation program and simulation engine as well as the interactions between them can not be evaluated through traditional V&V technology, so a new V&V pattern to solve this kind of problem based on dynamic policy enforcement is presented. The new V&V pattern contains six model elements and the constraint is formally described as policy. The policy is enforced by the policy engine and we can detect problems during simulation. Compared with traditional V&V technology, this framework is improved in checking behaviors and interactions between the program and engine at runtime, modifying and managing policies. It is easy to be used in the evaluation of simulation system so that mistakes in the system can be detected quickly and correctly.
