Abstract

'Goal Model' is core knowledge of 'Autonomic Control System' suggested to minimize human interference in system management. 'Autonomic Control System' performs 'Monitoring-Analysis-Plan-Execution', that is the four step of 'Autonomic Control', based on 'Goal Model'. Therefore, it is necessary to quantify achievement ratio of 'Goal Model' of target system. Thus, this paper present 'Probabilistic Evaluation of Goal Model' for methodology how to quantify achievement ratio of 'Goal Model'. It comprises 3-steps including 'Goal modeling and weighting', 'Goal model monitoring', 'Goal model evaluation and analysis'. Through these research, we provide core knowledge for 'Autonomic Control system' and it is possible to increase the reliability of system by evaluating 'Goal model' with applying weight. As case study, we apply 'Goal model' to a 'Smart IoT Kit' and we demonstrate the validity of the suggested research.

'목표모델'은 대규모 시스템의 관리에 인간의 개입을 최소화하기 위한 대안으로 제시된 '자율제어 시스템'의 지식 베이스이다. '자율제어 시스템'은'목표모델'을 기반으로 '자율제어'의 네 단계인 '모니터링-분석-계획-실행'을 수행하기 때문에 대상 시스템의 '목표모델' 달성 비율을 정량화할 필요가 있다. 따라서 본 논문에서는 '목표모델'의 달성비율을 정량화하기 위한 '목표모델의 확률적 평가'를 나타낸다. 평가는 '목표 모델링 및 가중치 부여', '목표모델 모니터링', '목표모델 평가 및 분석' 총 3단계로 구성되어 있다. 연구를 통해 '자율제어 엔진'에 지식 베이스를 제공하고, 가중치를 적용한 '목표모델'을 평가함으로써 시스템의 신뢰성 향상이 가능하다. 사례연구로써 'Smart IoT Kit'에 '목표모델'을 만들어 적용하여 제안 연구에 유효성을 입증한다.
