본 논문에서는 FMEA (Failure Mode Effect Analysis) 기법을 적용한 우편기계 유지보수 방법 제시하였다. 제안된 방법은 우편기계 모듈 및 부품에 대해 고장 유형을 정의하고, 고장 유형별 시스템에 주는 영향과 고장 빈도 및 검출도 등을 정의하여 고장 유형에 대한 시스템 위험도를 계산하여 그 값에 기반하여 점점 항목과 점검 주기를 조정하도록 하므로 시스템의 고장을 사전에 예방하고 시스템 가동율을 높이도록 하는 효율적인 유지보수 방법이다. 실제 현장에서 운영되고 있는 소형 통상 우편 구분 기계에 대해 제안된 방법의 적용 예를 보였다. 따라서 제안된 방법은 향후 국내 우편기계 유지보수에 적용시 유지보수 용이성과 효율성을 높일 것으로 기대한다.
