Abstract
Maintainability，as an important quality characteristic of the product, always been neglected during the design process, which lead to many problems around products’ useage. The main purpose of the Maintenance centered matrix-based Universal quality characteristics analysis is, by determining the qualitative and quantitative relationship between the general quality features, to find the data flow, information flow between the common quality features and maintainability. Focusing on the maintenance process in a typical maintenance task model, the maintenance factors and general quality characteristics involved in the maintenance task model are analyzed, and the quantitative or qualitative correlation between the maintenance factors and the general quality characteristics is obtained. Finally, The maintenance matrix model integrated with maintenance-oriented, integrated maintenance elements, design specialties and design elements is available. By combining maintainability factors(observation, inspection, disassembly, replacement, installation, commissioning) with other related design discipline factors, correlating other design elements with maintainability elements, reaching a systematic trade-off centered on maintainability, which take maintenance of all elements into account, into the pre-design process.
