一句话：通过系统性文献综述、行业调查与工具化流程设计，揭示嵌入式软件维护演化实践的碎片化问题并给出集成方案。
嵌入式软件广泛用于医疗、汽车、航空航天与物联网等安全关键领域，其维护和演化受硬件约束、实时需求及10–20年长生命周期影响，且60–90%的软件成本与其相关。然而工业实践仍碎片化，缺乏集成流程与专用工具。本博士研究结合系统性文献综述、行业调查，设计一套由软件工具支持的集成过程，并在真实医疗场景——低成本胰岛素输注泵中验证。初步结果揭示实践异质性、缺少标准化度量，以及处理技术债务与过时淘汰的困难。预期贡献包括统一流程、可操作工具，以及来自工业界与学术界的实证证据。
Embedded software is pervasive in safety-critical domains, including healthcare, automotive, aerospace, and the Internet of Things (IoT). Its maintenance and evolution are challenging due to hardware constraints, real-time requirements, and long life cycles, often exceeding 10–20 years. Studies indicate that 60–90% of software costs are related to evolution and maintenance. However, empirical evidence shows that current industrial practices remain fragmented, lacking integrative processes and specialized tools. This doctoral research addresses this gap by combining a systematic literature review (SLR), an industry survey, and the design of an integrative process supported by a software tool. The work will be validated in a real-world medical scenario: a low-cost insulin infusion pump. Preliminary results highlight heterogeneity in industrial practices, lack of standardized metrics, and difficulties in handling technical debt and obsolescence. The expected contributions include a unified process, an operational tool, and empirical evidence from both industry and academia.
