Abstract

An authentic simulation platform for events situated in spatio-temporal space is presented. The authenticity, i.e., logical fidelity to the reality, of this cyberspace is realized by maximizing the diversity and unpredictability of events occurring therein. The knowledge components and associated schemes required for the simulation of events situated in spatio-temporal space encompass the environmental factors, the objects, the events, and their interrelations. We deviled event activation, triggering mechanism, and cognitive function related to event to realize an authentic simulation of discretionary events. The agents in this simulation environments are autonomous in that they have their own existence and capability of event planning. We focused on identifying basic constructs relevant to authentic simulation of discretionary events whose initiation depends on human intention. Several key ideas are implemented in a typical spatio-temporal situation to demonstrate the viability of our simulation mechanism.

다양한 사건들의 무대로서의 시공간 상황의 구축을 위한 정통적 시뮬레이션 기반을 개발한다. 사이버 세계의 정통성, 다시 말해 실제에 대한 논리적 충실성은 그 세계에서 일어나는 사건들의 다양성과 예측 불가성을 최대화함으로써 실현한다. 시공간에서 일어나는 사건의 시뮬레이션을 위한 지식 컴포넌트는 환경 요인, 객체, 사건, 상관관계가 있다. 자유 재량적 사건의 정통 시뮬레이션을 실현하기 위해 사건 활성화, 실행 방법과 사건 인지 함수들을 고안하였다. 본 시뮬레이션 환경에서 자주적인 에이전트들은 독자적인 존재와, 사건의 실행과 분리된 계획을 하는 능력을 가지고 있다. 사람의 의도를 반영할 수 있는 자유 재량적 사건의 정통 시뮬레이션과 관련 있는 기본적인 구성 요소들을 확인하였다. 시뮬레이션 방법의 실행 가능성을 보이기 위해 핵심적인 기술들을 중심으로 구현의 예를 보인다.
