초록

본 논문에서는 D-정책을 갖는 이산시간 BMAP/G/1 대기행렬시스템의 일량을 분석한다. 유휴한 서버는 시스템에 도착한 고객집단의 서비스시간의 총합이 이미 정해진 일량 임계값 D를 초과하면 시스템에 서비스할 고객이 없을 때까지 서비스를 제공한다. 시스템의 안정상태 일량변환벡터를 유도하고 성능척도로서 평균일량을 구하였다. 시뮬레이션을 통해 이론값들의 타당성을 검증하고 간단한 수치예제를 보였다.

In this paper, we consider a general discrete-time queueing system with D-BMAP(discrete-time batch Markovian arrival process) and D-policy. An idle single server becomes busy when the total service times of waiting customer group exceeds the predetermined workload threshold D. Once the server starts busy period, the server provides service until there is no customer in the system. The steady-state workload distribution is derived in the form of generating function. Mean workload is derived as a performance measure. Simulation is also performed for the purpose of verification and a simple numerical example is shown.
