Abstract

Traditional system-oriented measures are no longer adequate to describe the availability perceived by the user. In this paper we investigate the service availability model and the user behavior graph. And we propose the simulation model, which determines the sevice availability considering user model, system model and service model at the same time. Through the example, we show how to construct the UBG of user model, system model and service model. And we investigate the effect of the parameters of system model and UBG on the service availability.

전통적인 시스템 차원에서의 신뢰도 분석 모형에서 탈피하여 사용자가 인지하는 서비스 가용도에 대한 필요성이 대두되고 있다. 본 논문에서는 우선 서비스 가용도 모형에 대해 살펴보고 이의 근간을 이루는 UBG에 대하여 논하였다. 그리고 사용자 모델, 시스템 모델 및 서비스 모델을 복합적으로 고려하여 서비스 가용도를 산출하는 시뮬레이션 모델을 제안하였다. 아울러 예제를 통하여 사용자 모델의 UBG와 시스템 모델을 작성하고 이를 토대로 서비스 모델을 정의하는 일련의 과정을 보여 주었다. 그리고 시스템 모델과 UBG의 여러 파라메타들이 서비스 가용도에 미치는 영향에 대해 살펴보았다.
