Abstract

This study addresses how to plan purchasing and leasing of containers to satisfy the demand on containers. The problem can be further decomposed into the long-term planning and the short-term scheduling. The long-term plan specifies the composition of owned containers, long-term leasing containers, and short-term containers. The short-term plan considers the seasonality of demand and determines the time of leasing and the amount of the short-term and the long-term leasing containers. The length of the planning horizon is 10-20 years for the long-term planning, while it is one year for the short-term planning. The time unit is one year for the long-term planning, while it is one month for the short-term planning. This study discusses how to estimate the demand of containers and proposes deterministic models for scheduling purchasing and leasing of containers.

선사에서 화물을 수송하기 위해 필요한 공(빈) 컨테이너 수요를 만족시키기 위해서 컨테이너를 구매하고 임대하는 계획을 작성하는 방법에 대해서 다루었다. 수요의 변동을 고려하여 각 기간별로 구매 또는 임대하여야 할 컨테이너의 개수와 임대기간을 결정하는 방법을 제시하였다. 컨테이너 구매 및 임대 계획작성을 위한 확정적 수리계획 모형을 제안하였으며 이 모형의 해를 구하기 위한 발견적 기법을 제안하였다.
