港務局橋式貨櫃起重機大修及汰換時程安排之研究

Abstract

貨櫃運輸係現今國際貨物運輸的主流，而台灣地區高雄、台中、及基 隆三個國際港口的競爭中，貨櫃的運量亦是決定其地位的重要指標。就基 隆港而言，橋式貨櫃起重機所表現的服務品質，對其競爭力有著重大的影 響。 本研究係探討基隆港橋式機的大修及汰換時程安排，並希望 藉由適當的排程來改善目前的服務品質。首先建立指標作為評量之基準， 繼續找出可行的時程安排，利用遺傳演算法尋優找出較佳排程方案。由分 析得知，橋式機的累計故障小時隨著大修或汰換後使用小時的增加而約略 成二次式的型態增加，而本研究排程目標所考慮的項目涵蓋故障率、停機 數量及成本。 Containerized transportation is the most important means in international cargoes shipping today. At present the port industries are competing strongly among Kaohsiung, Keelung, Taichung port in Taiwan. Container traffic is a majorindex to show the importance of the port in this competitive market. The service quality of container gantry cranes affects the Keelung port competitive power. The goal of this research is to study overhaul and replacement scheduling of container gantry cranes in Keelung port and hope to improve service quality by appropriate scheduling. This paper established indexes to estimate scheduling first , then finding fesible schedulings and using genetic algorithm to choose a better scheduling. The analysis shows that the accumulation of failure hours is a strictly increasing quadratic function of working hours after beginning ofoperation or overhaul. The objective of this research considered here includingfailure rate , the number of overhaul cranes and cost.
