Abstract
Line Replaceable Unit (LRU) is an important unit of the equipments and products. Improving LRU planning can improve the characteristics of RMS of the products, especially on the maintainability and reducing life cycle service cost (LCSC). This paper studies the relationship between LRU planning and Product design, and builds the frame of LRU planning combined with RMS design rules and requirements. Qualitative analysis and quantitative analysis are adopted to analyze and evaluate the LRU planning synthetically. Analysis and evaluation process include three steps: qualitative analysis, Mean Time To Repair (MTTR) quantitative analysis and LCSC quantitative analysis. The mothed in this paper can improve the status quo of traditional product design out of touch with the RMS design.
