Abstract

Blockchain was proposed in 2007 and began to be applied to actual services soon afterward. The railway system covers railroad construction and railway services. Because of the public characteristics of the railway system, it is expected that significant advantages can be obtained through the introduction of blockchain. Many benefits can be gained by applying the blockchain to them, but it is impossible to apply the blockchain to every part immediately due to the limitations of time and resources. Therefore, it is necessary to derive services or functions to which the blockchain will be applied and to select the part of them first. Since there are various evaluation criteria to derive the priority of blockchain adoption, systematic consideration is required. In this study, AHP was applied to calculate weights for evaluation criteria and systematical evaluation. Through the results of this study, it is expected that it is possible to build a roadmap for a next-generation railway system.

2007년에 제안된 블록체인은 곧이어 실제 서비스에 적용되기 시작하였다. 철도 시스템은 철도 건설 및 철도 서비스로 대표되는 분야에 관련된 다양한 분야를 포괄하고 있는데, 분야의 특성상 공공성이 강한 철도 시스템의 경우, 블록체인을 적용하여 많은 이점을 얻을 수 있을 것으로 기대되고 있다. 그러나 시간과 자원의 제약이 있어 이들 모두에 블록체인을 바로 적용하는 것은 불가능하다. 따라서 이들 중에서 블록체인을 적용할 서비스나 기능을 도출하고, 우선 적용할 대상을 선정하기 위한 연구가 필요하다. 블록체인 우선 적용 대상 선정에는 다양한 평가 기준이 존재하므로, 체계적인 고려가 필요하다. 본 연구에서는 AHP를 적용하여 평가기준에 대한 가중치 산출 및 적용 대상에 대한 체계적인 평가를 시도하였다. 본 연구의 결과를 통하여 차세대 철도 시스템 로드맵 작성에 도움이 될 것으로 기대된다.
