  • Generally, the container road transportation can be divided into three types; short distance, long distance and shuttle transportation. Specially, the shuttle service occurs several amounts of container which is same as O/D pairs. Also container vehicle can be divided into three types according to the chassis types of vehicle; only 20-feet container, only 40-feet container and combined chassis trailer. Combined chassis trailers can load two 20-feet containers or one 40-feet container. This paper deals with Vehicle Routing Problem (VRP) for delivering containers considering shuttle service. This problem is similar to the previously studied Shin and Oh (2008), but the characteristics of shuttle service must be considered additionally. We formulate the container shuttle transportation planning problem using combined chassis trailers based on VRP with pick-up and delivery which can visit each node more than one time, and propose an efficient solution procedure.

  • To determine the optimum harvesting methods for high yield and quality, harvesting time were tested from 30 to 45 days after heading with five days intervals, using combine, binder and knap-sack type reaper (KSTR) in harvesting machines. Under the consideration of moisture contents of grain, operating time, grain loss, harvesting cost and quality, the optimum time of barley harvesting for mechanization was 35 to 40 days after heading. Combine and binder were recommended as the suitable machines for barley harvest in the operating efficiency and harvesting cost.

  • Alternatives for increasing the competitiveness of locally manufactured agricultural machinery in domestic and foreign markets has been proposed. This was done by analyzing the major agricultural machinery's price and market share as well as their performance and quality. In the Korean domestic market, the market share of Japanese agricultural machinery has been identified to be 14.5% for tractors, 31.1% for combine harvesters, and 35.8% for rice transplanters, and on track for further increase. Japanese manufacturers' domestic patent shares are 58.5% for tractors, 79.9% for combine harvesters, and 69.8% for rice transplanters, showing the dire need for Korean domestic firms to expand their technological rights. To strengthen the industrial competitiveness of agricultural machinery, therefore, researches that develop the fundamental and elemental technology to reduce the frequency of breakdown should be needed in the short term. To achieve this, it is imperative to establish technology roadmap, promote greater cooperation between academia and industry, and systematically increase research funding. In addition, as a long-term solution for enhancing the competitiveness, an establishment of Agricultural Equipment Technology Institute is strongly recommended to systematically support R&D for developing core technologies, particularly high-quality components that guarantee durability and quality.

  • 우리나라 콩 재배면적은 약 8만ha로 벼 다음으로 많이 재배되고 있는 작물이지만, 아직 기계화 작법 시스템이 정착되어 있지 않다. 기계화가 보편화되지 못하고 있는 원인으로는 영세한 경영규모와 다른 작물에 비하여 낮은 수익성 등을 들 수 있다. 특히, 작업 단계 중에서 콩 수확작업의 기계화는 21%로 매우 낮은데 이에 대한 원인분석과 대책이 시급한 실정이다.
