Continuous Modeling in Aircraft Mission Analysis and Simulation

Mission analysis is the initial process in aircraft development. Its goal is to understand how the aircraft will operate and interact with other systems to accomplish its mission. As a system of systems (SoS) level development process, mission analysis involves various multi-disciplinary and cross-domain models, such as battlefield plotting models, scenario visualization models, SoS architecture models, and multi-agent wargaming models. This results in a heavy modeling workload and presents a significant challenge in maintaining model consistency. To ensure model transferability and consistency, this paper introduces a continuous modeling method for aircraft mission analysis. With the help of a modeling language-independent ontology, it achieves preliminarily model transformation and data transfer between the four kinds of models used in aircraft mission analysis. According to the practice, the continuous method helps improve the continuity and consistency of models and reduce the workload of building and maintaining models.
