Abstract

In this paper, we conducted a conventional regression and fuzzy regression analysis of the core competencies of construction subcontractors. The study was undertaken to check whether these two types of regression core capabilities affect the rating of construction subcontractor. Conventional regression result showed some effect on the rating of construction subcontractors on which core competencies to management and firm contribution were conducted. With fuzzy regression analysis, on the other hand, the rating of construction subcontractors could see the Min and Conjunction problem which utilize 100% reliability of Min. Max and Conjunction. From the above, the dependent variable of conventional regression could determine the evaluation grade of construction subcontractor. The fuzzy regression analysis shows the estimator of evaluation grade of the construction subcontractor including or corresponding to the fuzzy output data.

본 논문은 건설협력업체의 핵심역량 대하여 일반회귀분석과 퍼지회귀분석을 실시하였다. 이것은 핵심역량이 건설협력업체의 등급에 어느 정도 영향을 주는 지에 대하여 두 종류의 회귀분석으로 확인하기 위한 것이다. 건설협력업체 평가등급에 대한 일반회귀분석 결과에서 건설협력업체의 등급결정에 영향을 주는 핵심역량은 경영과 업체기여도 임을 알 수 있다. 건설협력업체 평가등급에 대한 퍼지회귀분석은 Min, Max, Conjunction 중에서 Min, Conjunction 문제는 100%의 신뢰성이 있어 활용이 가능함을 알 수 있었다. 이상으로부터 일반회귀분석은 종속변수인 건설협력업체의 평가등급에 영향을 주는 핵심역량의 파악이 가능하며, 퍼지회귀분석은 주어진 퍼지출력데이터를 완전히 포함하던지 걸쳐지던지 한 점에 일치하는 건설협력업체 평가등급의 추정치를 보여 주고 있다는 것을 알 수 있다.
