Abstract

In this paper, it shows optimal inventory level of bicycle sharing service terminal by maintaining the lowest costs. As the interest to environment and exhaustion of resource increases globally, investment to sustainable transportation increases around advanced countries and interest to efficient transportation, managing and consuming of vehicle increases also. Vehicle sharing service is a model of rental car where customer rent cars for short periods of time often by the hour and its users are increasing for the reason that it is more convenient than car rent. In addition, bicycle sharing service is one of the major parts in vehicle sharing program and many of country are already managing it. This paper proposes optimal inventory levels of vehicle sharing service's terminal by using simulation calculating operation costs of vehicle sharing service.

본 논문에서는 자전거 쉐어링 사업을 중심으로 창원시 누비자 자전거 쉐어링 서비스의 최적 재고 수준을 유지하며 시스템 운영비용을 최소화하는 방법을 제안한다. 쉐어링 서비스란 일반적으로 시간단위로 차량을 렌트하는 개념으로 렌터카보다 편리한 서비스로 이용자의 수가 많아지고 있는 추세이다. Vehicle sharing service는 다음 세대 차량과 함께 sustainable transportation 의 수단으로써 급부상하고 있다. 지구 온난화의 심화와 함께 이산화탄소 배출량의 감소에 관심이 집중되면서 기존의 차량의 내연 기관을 하이브리드 혹은 전기차로 변화하고 있으며, 기존의 대중교통 시스템을 다각화로 발전하고 있다. 그 중 실현 가능성이 높은 분야인 자전거 쉐어링 분야이며, 이미 지방 자치 단체 중심으로 자전거 쉐어링 사업이 이루어지고 있다. 본 연구에서는 자전거 쉐어링 서비스의 각 터미널간 최적 자전거 보유수준(S-s)을 제안하는 시뮬레이션을 설계하여 운영비용을 최소화시키는 자전거 터미널의 재고수준을 제안하였다.
