Abstract

Reliability growth analysis was conducted for a guided weapons system. In the development phase, reliability management activities were continuously carried out by identifying failure modes and causes and analyzing faults found during the testing. The missile system consists of an all-up-round missile and a launcher, and the analysis was carried out according to the test results of each system. The test results for the all-up-round missile were obtained with discrete data, which were success and failure as a one-shot-device. The test results for the launcher were obtained with continuous data by operating the equipment continuously in the test. For each test result, the reliability growth model was applied to the Standard Gompertz model and the Crow-Extended model. The models were used to identify the growth analysis results of the test so far. It was also possible to predict the reliability growth results by assuming the future test results. The study results could be useful in achieving the desired reliability goal and in determining the number of tests. Then, the planned test will be confirmed and the growth analysis of the missile system will continuously be conducted.

본 연구에서는 특정 유도무기체계에 대한 신뢰도 성장 분석을 수행하였다. 개발단계에서의 시험을 통해 고장 모드와 원인을 식별하고 시험 중 발견된 고장을 분석하여 지속적인 관리 활동을 수행하고 있다. 해당 유도무기체계는 유도탄과 발사 체계로 구성되어 있으며, 각 장비의 시험 결과에 따라 신뢰도 성장 분석을 실시하였다. 유도탄의 경우에는 일회성 무기로 성공과 실패인 이산형 데이터로 시험 결과를 획득하였다. 발사체계의 경우에는 시험에서 지속해서 장비 운용을 하여 연속형 데이터로 시험 결과를 획득하였다. 각각의 시험 결과 형태로 신뢰도 성장 모델을 Standard Gompertz 모델과 Crow-Extended 모델을 적용하였다. 해당 모델을 사용하여 현재까지 수행한 시험 결과에 대한 신뢰도 성장 분석 결과를 확인하였다. 또한 미래에 수행될 시험 결과를 가정하여 신뢰도 성장 결과를 예측할 수 있었다. 본 연구는 해당 유도무기체계의 신뢰도 목표값을 달성하고 시험 횟수를 결정하는데 있어 유용하게 활용될 수 있을 것이다. 그리고 이후 계획된 시험을 확인하여 해당 유도무기체계에 대한 신뢰도 성장 관리를 지속적으로 추진할 예정이다.
