조선해양 일정관리 시뮬레이션을 위한 자료구조의 표준화 개발과 품질 평가 방법

Abstract

The scheduling system in shipbuilding process is susceptible to various plan changes and thus is difficult to predict in advance. Estimation of workloads and resulting processing time have been a challenge to enhance productivity. To overcome the above drawbacks, an effort to utilize computer-based simulation has been continuously made. However, the simulation in most cases has been carried out for one time use at a specific shipyard and thus customization for each shipyard has to be repeatedly made.

In this paper, an approach for the standardization of planning data of midterm scheduling system is presented. First, the structure of complex planning data system is analyzed and a common structure that facilitates the simulation by converting the custom data into standardized format is constructed. Also, an XML-based translator is developed. Verification of developed data structure is carried out in a .NET-based application. Finally, the data required for the simulation are qualitatively analyzed and verified and a method for data quality assessment is proposed.
