An application of design structure matrix methods to explore process improvements in aircraft fight line operations

Abstract

The complexities around building, testing, and flying aircraft span many different domains. Some of these domains include processes, people, and tools, of which affect the way work is performed on aircraft. In this thesis, communication tools and the organizations involved in troubleshooting and readying aircraft for flight at an aircraft manufacturer's flight line was analyzed using Design Structure Matrix (DSM) methods. Mapping the two DSMs together into a larger multi-domain matrix (MDM) provided insight to the ways information is transferred, and clarified ways to streamline available information to the various stakeholders, while reducing effort and increasing information quality. One recommendation to streamline flows was to design a system that leverages existing responsibilities of Manufacturing, Quality and Engineering and applying them in an electronic format by utilizing computers (a tool found at every level of employee) to capture live data in an organic fashion. The proposed solution would provide valuable information to other stakeholders at a reduced effort, translating to savings. Savings in the form of interaction reductions could range from 235 to 117, at a 50% reduction in interactions across all organizations. It would also provide a method by which to share information at faster speeds, ensuring all stakeholders are engaged with the latest information. Information quality and speed would further help reduce the risk of flight delays, and improve the customer experience. Overall, reductions in efforts from all organizations and an improved customer experience through rapid and accurate information dissemination, will ultimately reduce cost and promote business and growth.
