Abstract
It is difficult to evaluate the performance of process innovation of e-procurement which has large scale and complex processes. The existing evaluation methods for measuring the effects of process innovation have been mainly done with statistically quantitative methods by analyzing operational data or with qualitative methods by conducting surveys and interviews. However, these methods have some limitations to evaluate the effects because the performance evaluation of e-procurement process innovation should consider the interactions among participants who are active either directly or indirectly through the processes. This study considers the e-procurement process as a complex system and develops a simulation model based on MAS(Multi-Agent System) to evaluate the effects of e-procurement process innovation. Multi-agent based simulation allows observing interaction patterns of objects in virtual world through relationship among objects and their behavioral mechanism. Agent-based simulation is suitable especially for complex business problems. In this study, we used Netlogo Version 4.1.3 as a MAS simulation tool which was developed in Northwestern University. To do this, we developed a interaction model of agents in MAS environment. We defined process agents and task agents, and assigned their behavioral characteristics. The developed simulation model was applied to G2B system (KONEPS: Korea ON-line E-Procurement System) of Public Procurement Service (PPS) in Korea and used to evaluate the innovation effects of the G2B system. KONEPS is a successfully established e-procurement system started in the year 2002. KONEPS is a representative e-Procurement system which integrates characteristics of e-commerce into government for business procurement activities. KONEPS deserves the international recognition considering the annual transaction volume of 56 billion dollars, daily exchanges of electronic documents, users consisted of 121,000 suppliers and 37,000 public organizations, and the 4.5 billion dollars of cost saving. For the simulation, we analyzed the e-procurement of process of KONEPS into eight sub processes such as 'process 1: search products and acquisition of proposal', 'process 2 : review the methods of contracts and item features', 'process 3 : a notice of bid', 'process 4 : registration and confirmation of qualification', 'process 5 : bidding', 'process 6 : a screening test', 'process 7 : contracts', and 'process 8 : invoice and payment'. For the parameter settings of the agents behavior, we collected some data from the transactional database of PPS and some information by conducting a survey. The used data for the simulation are 'participants (government organizations, local government organizations and public institutions)', 'the number of bidding per year', 'the number of total contracts', 'the number of shopping mall transactions', 'the rate of contracts between bidding and shopping mall', 'the successful bidding ratio', and the estimated time for each process. The comparison was done for the difference of time consumption between 'before the innovation (As-was)' and 'after the innovation (As-is).' The results showed that there were productivity improvements in every eight sub processes. The decrease ratio of 'average number of task processing' was 92.7% and the decrease ratio of 'average time of task processing' was 95.4% in entire processes when we use G2B system comparing to the conventional method. Also, this study found that the process innovation effect will be enhanced if the task process related to the 'contract' can be improved. This study shows the usability and possibility of using MAS in process innovation evaluation and its modeling.

Abstract
방대한 규모와 복잡한 프로세스로 구성된 공공조달의 혁신성과를 평가하기란 매우 어려운 문제이다. 기존의 프로세스 혁신 평가는 주로 설문 및 인터뷰, 그리고 운영데이터를 분석한 정성적, 또는 통계적인 정량적 방법들이었다. 이에 본 연구에서는 공공조달 프로세스를 복잡계로 보고 이에 대한 시뮬레이션 방법으로 멀티에이전트시스템(MAS)을 이용하여 공공조달 프로세스 혁신효과 평가모델을 개발하였다. 그리고, 개발된 MAS 기반의 공공조달 혁신평가 모델을 우리나라 조달청의 G2B(나라장터, KONEPS) 시스템에 적용하여 혁신효과를 평가하였다. MAS 시뮬레이션 도구는 Northwestern University에서 개발된 Netlogo Version 4.1.3을 사용하였고, 모델링에서는 에이전트 정의, 에이전트 행동특성 정의, 에이전트 관계 정의의 세단계로 진행하였다. 첫째, 에이전트 정의에서는 에이전트가 될 대상을 선정하고, 에이전트가 가진 속성과 변수들을 정의하였다. 둘째, 행동특성 정의에서는 각 에이전트의 행동계획 및 자원할당을 설정하였고, 셋째, 관계정의 단계에서는 상태변화에 따른 행동 규칙을 설정하였다. 또한 프로세스 혁신의 목적에 맞는 성과를 측정하기 위하여 혁신 효과평가항목을 선정하였고, 데이터는 조달청의 협조를 통해 DB 데이터와 설문데이터를 활용하였다. 이를 통해 프로세스 전체 및 프로세스별 절감시간과 업무량의 절감율을 측정하였다. 실험결과 전체 프로세스의 효율성이 증대되었으며 '평균 업무처리 건수'의 절감율이 92.7%, '평균 업무처리 시간'의 절감율이 95.4%로 나타났다. 즉 공공조달분야는 G2B 시스템 도입을 통해 프로세스 혁신을 추진한 결과 매우 높은 효율성이 제고된 것으로 분석되었다. 또한 본 연구를 통해 '계약'과 관련한 업무프로세스에서 추가적인 개선이 이루어질 경우 프로세스 혁신효과가 더욱 향상될 수 있는 것으로 분석되었다. 본 연구는 MAS를 이용하여 프로세스 개선효과에 대한 평가모델을 제시하고 분석했다는데 의의가 있다.
