Decision technique for accommodation facilities of multi-utility tunnel in basic planning phase

기본 계획 단계에서의 공동구 수용시설물 결정 기법

Abstract

In this paper, we propose a method to determine whether to install the accommodation facility of the multi-utility tunnel more effectively in the basic planning phase, and to set up an evaluation system to determine the configuration and kind of accommodation facility. For the configuration of the accommodation facility, 98 alternatives were analyzed for 7 accommodation facility. For the evaluation system of the accommodation facility, index related to feasibility and economic in basic planning phase were selected. The evaluation system classified as spatial, effective, and cost evaluation was presented reflecting the selected index, and AHP analysis was performed for weight setting. The results of this study will be helpful for users including designers to shorten the time and increase the efficiency in the process of determining accommodation facility of the multi-utility tunnel in basic planning phase.

본 논문에서는 공동구 도입과 관련하여 초기 기본 계획 단계에서 보다 효율적으로 수용시설물의 설치여부를 결정하기 위한 기법을 제시하였다. 이를 위해 수용시설물의 구성과 종수를 결정하기 위한 평가체계를 정립하였다. 7개의 수용시설물에 대하여 98개의 조합을 분석하였으며, 수용시설물 평가체계를 위하여 타당성 및 경제성과 관련된 지표 중 기본 계획단계와 관련된 지표를 선별하였다. 선별된 항목을 반영하여 공간적, 효과적, 비용적 평가로 분류된 평가체계를 제시하였으며, 가중치 설정을 위한 AHP분석을 실시하였다. 본 연구의 결과는 공동구 설치를 위한 기본 계획 단계에서 설계자를 포함한 사용자들이 공동구내 수용시설물을 결정하는 과정에서 시간을 단축하고 효율성을 높이는데 도움이 될 것으로 판단된다.
