Abstract:

Simulation system is composed of models and simulation data. The credibility of simulation system depends on the credibility of models and the quality of data. The simulation data quality relies on data verification, validation and certification when simulation system is developed. The lack of implementation strategies of VV&C and tools is a big problem. Firstly, the concept of data quality and VV&C was introduced in this paper. Secondly, the effect of VV&C was analyzed in the circle of data manufacture and usage from the views of data producer and user. Thirdly, the implementation strategies of VV&C for different data participants were employed: data quality can be recorded by data producer with data quality metadata, and VV&C can be carried out by data user with VV&C process model. Finally, based on VV&C process model, PVV&CM for VV&C management was developed by using management workflow, and the VV&C process can be managed as a flow and be carried out with standard.
