abstract = {With the raising complexity of modern civil aircraft, both academy and industry have shown strong interests on MBSE (Model-Based System Engineering). However, following the application of MBSE, the duration of the design phase exceeded expectations. This paper conducted a survey to the relevant participants involved in the design, revealed that a lack of proper process management is a critical issue. The current MBSE methodology does not provide clear guidelines for monitoring, controlling, and managing processes, which are crucial for both efficiency and effectiveness. To address this, the present paper introduced an improved Process Model (PM) within the MBSE framework for civil aircraft design. This improved model incorporates three new Management Blocks (MB): Progress Management Block (PMB), Review Management Block (RMB), and Configuration Management Block (CMB), developed based on the Capability Maturity Model Integration (CMMI). These additions aim to streamline the design process and better align it with engineering practices. The upgraded MBSE method with the improved PM offers a more structured approach to manage complex aircraft design projects, and a case study is conducted to validate its potential to reduce timelines and enhance overall project outcomes.}
