초록

프로세스 마이닝에서는 일반적으로 SAP ERP와 같은 정보시스템이 남기는 시스템의 디폴트 로그를 분석해왔지만, RPA라는 자동화 소프트웨어의 사용이 확대됨에 따라 RPA 봇이 남기는 로그를 활용할 수 있게 되었다. 본 연구에서는 RPA 봇을 국내 제조기업(코스메틱 분야) 3개 사의 업무에 적용하여 로그를 남긴 후 분석함으로써 현업의 RPA 자동화에 대한 실제 현황을 파악하였다. Uipath와 파이썬을 이용하여 RPA 봇을 구현하고 로그를 남겼으며, 봇이 남긴 로그의 분석을 위해서는 프로세스 마이닝 전용 소프트웨어인 Disco를 사용하였다. 프로세스 마이닝을 통해 봇의 활용성과 성능이라는 두 측면에서 로그 분석을 해 본 결과, 개선 요구사항을 찾아볼 수 있었다. 특히 봇의 활용성 측면에서 활용도를 높여야 하는 경우가 많았고, 수행과정에서 오류나 예외발생 및 수행시간이 길어지는 구간이 발견된다는 점에서 모든 사례에서 개선 지점이 존재하고 있는 것으로 분석되었다. 이러한 분석은 설문이나 인터뷰에 의존했던 기존의 정성적 방법이 아닌 데이터를 활용한 증거 기반의 분석으로 봇의 자동화 현황과 성과를 분석한다는 점에서 매우 과학적이며 또 현업의 업무에 적용된 사례라는 점에서 실증적 의미를 갖는다. 나아가 '로그 마이닝 기반 자동화 현황 분석'은 봇 행동 최적화를 위한 의미있는 기초 단계로, 궁극적으로 프로세스 경영을 수행할 수 있는 토대가 된다고 볼 수 있다.

Process mining has generally analyzed the default logs of Information Systems such as SAP ERP, but as the use of automation software called RPA expands, the logs by RPA bots can be utilized. In this study, the actual status of RPA automation in the field was identified by applying RPA bots to the work of three domestic manufacturing companies (cosmetic field) and analyzing them after leaving logs. Using Uipath and Python, we implemented RPA bots and wrote logs. We used Disco, a software dedicated to process mining to analyze the bot logs. As a result of log analysis in two aspects of bot utilization and performance through process mining, improvement requirements were found. In particular, we found that there was a point of improvement in all cases in that the utilization of the bot and errors or exceptions were found in many cases of process. Our approach is very scientific and empirical in that it analyzes the automation status and performance of bots using data rather than existing qualitative methods such as surveys or interviews. Furthermore, our study will be a meaningful basic step for bot behavior optimization, and can be seen as the foundation for ultimately performing process management.
