Model engineering for complex system simulation

Model is the foundation of system simulation, especially for complex system simulation, and the key that guarantees the trustiness of simulation results is to construct a dependable model. To meet the challenges of model development and management of a complex system, the concept of model engineering was proposed, which aimed at setting up a systematic, normalized, and quantifiable engineering methodology by exploring basic principles in model construction, management and maintenance to manage the data, processes and organizations/people involved in the whole lifecycle of a model to obtain a dependable model. The meaning and contents of model engineering were given, and a set of key technologies were introduced. A preliminary framework of the body of knowledge of model engineering was given based on software engineering, system engineering and some other relative disciplines.
