외래환자 진료 프로세스를 위한 인터넷 기반 Generic 시뮬레이션 모델

This paper introduces an Internet‐based generic simulator for outpatient clinics, named PIOS (Postech Internet‐based Outpatient Simulator). Unlike other simulation tools, PIOS is operated on the Internet, is straightforward to use for outpatient process analysis, and is open to public via http://logistics.postech.ac.kr/pios with free of charge. Therefore, non‐simulation expert users such as hospital administrators and managers can easily access to PIOS and conduct simulation study by themselves. In this paper, we describe the main components and programming logic of PIOS, and demonstrate its validity by comparing the output results of PIOS and a commercial software package.
