R&M Analysis of Three Load Sharing Power Forms Intermixed on Common Replaceable Modules

Trade studies aid design, influencing outcomes through characterization of controllable variables. When existing tools require simplifying assumptions to fit the mold where uniqueness exists, one may be left with some cloud of doubt and the potential to make flawed choices. Exploiting modeling and simulation through macros in MS Excel® can remove the assumptions and doubt. This presentation will demonstrate the ease of incorporating such uniqueness for complete characterization of reliability, maintainability, availability, and life cycle cost (LCC) trade space variables. This will be accomplished "pictorially" using reliability block diagrams (RBDs) with time-varying failure rates, multiple restoration choices and "simple" macros.
