Study on multidisciplinary nested modeling and parallel simulation

This paper aims at designing a modeling approach for multidisciplinary integration complex product. A new ideology is introduced, that each subject is taken like a subsystem, using a nested structure as its autonomous model, and each autonomy model paralleling its counterparts. The dynamic autonomy model can be expressed in a universal format, with the Parameters Pool (PP) and the Coupling Estimate (CE) two items, reflecting parameters' alteration and the total impact of other interaction's subjects, respectively. The model of PP and CE nested in the autonomy model. All state variables are shared through the data exchange interface between each subsystems, and the coupling of interdisciplinary is implemented by PP and CE. Each subject has an enable coefficient for its working state, which can implicate single subject real-time plugging and pulling, such as systems change during hardware-in-the-loop- simulation and random noise. Also, this modeling approach can be easily used for multi-disciplinary, distributed integration platform. Two examples are provided to check its accuracy and illustrate its application.
