시공단계 설계변경의 동적 특성 분석

Change orders in construction project during their execution are major causes for time delays, cost overruns, lower labor productivity, claims and other negative impacts. Many researchers worldwide have studied causes and effects of change orders using valuable empirical approaches, however, very few offered a comprehensive, systematic and dynamic overview. The objective of this study is to analyze the dynamic behavior of change orders in construction phase through qualitative system dynamics modeling, then propose the guidelines for efficient construction management and improved delivery methods.
