무기체계의 상세설계 단계에 적용을 위한 한국형 정비도 예측 S/W 개발

Abstract

Maintainability is a major design parameter that includes availability as well as reliability in a RAM (reliability,availability, maintainability) analysis, and is an index that must be considered when developing a system. There is alack of awareness of the importance of predicting and analyzing maintainability; therefore, it is dependent onpast-experience data. To improve the utilization rate, maintainability must be managed as a key indicator to meet theuser's requirements for failure maintenance time and to reduce life-cycle costs. To improve themaintainability-prediction accuracy in the detailed design stage, we present a maintainability-prediction method thatapplies Method B of the Military Standardization Handbook (MIL-HDBK-472) Procedure V, as well as a Koreanmaintainability-prediction software package that reflects the system complexity.
