Abstract

Container terminal yards operate under a high degree of uncertainty as the contact point between inbound and outbound operations of vessels and external trucks. The layout, equipment operations. and job orders at the yards determine the efficacy and delays of the work, so many studies have investigated improvements in efficiency. H company, a container terminal operator developed an index called WDI to distribute work among RTGCs. The WDI is an indicator to prevent congestion in one place by equally distributing the work to each RTGC. This paper analyzes the effect of the WDI introduction and discusses the causes and results of the WDI introduction effect from quantitative and qualitative perspectives.

컨테이너 터미널의 장치장은 선박의 입출항과 관련된 작업과 외부트럭의 반출입과 관련된 작업이 만나는 접점으로 높은 불확실성을 가진다. 장치장의 레이아웃과 장비의 운영방식, 작업 순서에 따라 작업의 지연과 원활함이 결정되므로 높은 작업의 효율을 위해 많은 연구가 이루어져 왔다. 터미널 운영사인 H사는 높은 작업 부하가 한 곳에 집중되는 것을 방지하기 위해 작업을 여러 군데 분산시키고자 WDI라는 지표를 개발하여 활용하고 있다. WDI는 각 RTGC에 동등하게 작업을 배분하여 한 곳에 정체가 발생하지 않도록 하고자 H사에서 사용되는 지표로서 본 논문은 WDI도입의 효과를 분석하고 WDI도입 효과의 원인과 결과를 정량적 측면과 정성적 측면으로 파악한다.
