The Technology of Building Complex Models in the Simulation Modeling Infrastructure
In the paper the technology for constructing complex simulation models of spacecraft onboard equipment based on the European Space Agency standard — Simulation model portability (SMP2) are proposed. The standard provides the principles of portability and reuse of simulation models. In addition to SMP2-models, virtual instruments and logical models the rules of which are set in knowledge bases are used in the work. The goal of the technology is to ensure the interaction of heterogeneous simulation models, their integration based on the principles of portability and universality of the SMP2 standard. The technology is based on the formalization of models. The model contains structural-parametric and functional description of the elements determining its composition and features, as well as the method of control of transitions between the conditions under modeling. The principles of unification allowing to build a model in the terms of the subject area, with their following translation to the program elements of the model working in accordance with the SMP2 standard are suggested. This approach allows the onboard equipment designer to understand both created by own models, and models created by other specialists, and also to represent the simulated system as a whole. The technology is tested in software designed for simulation of satellite systems. The construction of complex simulation models will make to provide accumulation and usage of expert knowledge about spacecraft onboard equipment functioning.
Keywords: spacecraft, onboard equipment, simulation modeling, simulation model portability standard (SMP2), simulation modeling infrastructure.
