The weapon systems development has some distinct characteristics in that a big size of government budget (derived from national tax) has been expended frequently and the completion of the development projects seems to take long. Thus, the impact of the potential changes in the required operational capability on the development activities can induce some type of project risks. As such, proper management of project risk has been one of crucial subjects in the weapon systems development. Although a variety of methods can be considered, an approach based on the test and evaluation (T&E) process has been selected in this paper in order to appropriately handle those potential risks. In the study of the underlying T&E process, the safety consideration (for instance, explosiveness) of weapon systems is also included. To achieve the objective of the paper, a step-by-step procedure is first presented in the analysis of the T&E process. Then, to pursue some enhancement on the process, a set of necessary and useful activities are added in terms of risk and safety management. The resultant process is further analyzed and tailored based on a design structure matrix method. The case study of a tank development is also discusse

우리나라에 주기적으로 내습하여 막대한 인명 및 재산피해를 발생시키고 있는 태풍의 재해위험도를 EST 기법을 적용하여 평가하였다. 서울을 비롯한 6개 주요 도시에 대하여 기존의 태풍자료를 Training Set으로 사용하여 In년 간의 태풍 모의 기간에 대하여 100회 반복모의를 수행한 결과로부터 재현기간별 최대풍속과 일최대강우량의 평균값, 표준편차, 최소값 및 최대값을 추정하였다. 재현기간 100년의 태풍에 대한 최대풍속의 평균값을 비교 평가한 결과 태
