PBSE Data Initialization Framework and Practice by Using LLM

With the increasing complexity of commercial aircraft and the rapidly changing market demands, the system engineering development pattern extensively adopted by aircraft OEM has evolved from the traditional “Document-Based Systems Engineering (DBSE)” to “Model-Based Systems Engineering (MBSE)” and “Pattern-Based Systems Engineering (PBSE).” MBSE employs models to describe products, while PBSE builds upon MBSE by utilizing engineering patterns, which are validated in advance, to enhance the efficiency and quality of data production in both MBSE and DBSE. However, during PBSE engineering practices, we have observed certain challenges, such as the barriers to initializing product S* model and the low efficiency in generating instance.
