    One of the methodologies to implement product/service development strategies that would efficiently boost product reliability, availability, maintainability and economic performance is called RAM (Reliability, Availability and Maintainability) analysis. We have been working on finding solutions to improve the availability and economic performance of the various different products that MHI Group produces, utilizing RAM analysis in collaboration with experts in the design, service and R&D departments. While we conduct RAM analysis on actual products, to widen the application range thereof, we have been working on the development of new methodologies including a proprietary risk assessment framework. This paper introduces an overview of RAM analysis, our new risk assessment framework and some examples of RAM analysis applications.
