ATC 작업 효율화를 위한 자동화 컨테이너 터미널의 장치장 할당 모형

Abstract

According to increasing the marine transportation business and over sizing transportation system, the necessity of automated container terminal system is required recently. In automated container terminal, especially the design of overall effective operating system which includes the allocation problems of yard space and yard equipment is one of important facts.

In this thesis, we deal with an allocation model of vertical type container yard for minimizing the total automated transfer crane's (ATC) work time and the equivalence of ATC works load in each block on automated container terminal.

Firstly, a layout of automated container terminal yard is shown and compared with that of conventional container terminal. The characteristic of equipment which is operated in the terminal and basic assumption are given. Next, an allocation model which concerns with minimizing the total work time and the equivalence of works load is proposed for the high effectiveness of ATC work in automated container terminal. Also, a weight values on critical function are suggested to adjust the critical values by evaluating the obtained allocation plan. To find the solution of allocation model in given terminal yard situation, a genetic algorithm (GA) is applied, where the real information of container terminal is used. In simulation, the weight values are designed by planner as ones experience, and its result presents the effectiveness of selecting the weight value. Thus, the proposed allocation model and its solution method by GA can be useful to help the planning the allocation plan in automated container terminal.
