  • 조선사는 선주와의 계약에 의한 수주 생산방식으로 계약시 명시된 작업시작일, 도크작업시작일 진수일, 인도일을 지키기 위한 공정별 목표 생산완료일을 결정하게 되고, 각 공장별로 목표 생산완료일을 지키기 위한 일정계획을 수립하게 된다. 생산되는 선박은 선종, 선형에 따라 구성되는 블록의 수가 다르고 그 형태도 매우 다양하다. 그러므로 선박을 건조하기위해 제작되는 블록의 정확한 작업공기와 공수를 예측하기가 매우 어렵다. 본 논문에서는 불확실한 작업공기와 공수를 이용하여 작업장의 공간제약을 고려한 일정계획을 수립하는 문제에 대하여 기존의 공간제약 문제에 대한 연구에서 나아가 실행 단계에서의 운영프로세스를 개선하여 적용하는 연구를 수행하였다. 이번 연구의 결과로 목표 생산계획과 부서계획, 실행 실적을 과거 데이터와 비교분석 하여 개선된 운영프로세스의 효과를 검증하였다.

  • Considerable number of offshore platforms have been built in Korean shipyards ever since 1976. Unlike for the cases of building ships, however, negligible efforts have been made to establish planning methodology for building onshore platforms. Severe congestion has been shown in the processes of assemblying modules of platforms. The module which is the upper part of a platform is a steel structure accommodating various types of outfittings and machinaries. The production planned without proper consideration on allocating work loads by trade used to show severe interferences among trades of workers and resulted in delayed completion. In this paper, a method of planning module assembly in consideration of leveling work loads by trade is discussed. A system of planning has been formulated and tested on a exampled case of producing a mix of 72 modules. The test showed a possibility of saving 31% of manpower and trimming 11% of through put time.

  • The historical value of the official documents of the Government General of Choson preserved as permanent archived documents has long been recognized. However, the fact that only parts of the overall documents were preserved and that the contents of the existing documents is not uniform, results in many problems regarding the evaluation and usage of such documents as archives. This study attempts to appraise a series of archival documents related to urban district planning compiled during the colonial era. Although limited in terms of its applicability to the development of an evaluation method for the official documents of the Government General of Choson as a whole, by evaluating the value of these documents based on the background of the documents produced during the Government General of Choson's implementation of its colonial policy, this study provides an important indicator of how such documents should be used in the future. On the other hand, the assessment of historical records such as the official documents of the Government General of Choson which have already been designated and preserved as permanent archived documents should not be perceived as an attempt to dispose of the relevant documents. With regard to the appraisal of historical archives, it is necessary to consider measures to link such documents with existing databases or information contents in order to heighten access to and usage of the relevant documents in the future.
