OLAP를 이용한 설계변경 분석 방법에 관한 연구

Abstract

Engineering changes are indispensable engineering and management activities for manufacturesto develop competitive products and to maintain consistency of its product data. Analysis ofengineering changes provides a core functionality to support decision makings for engineeringchange management. This study aims to develop a method for analysis of engineering changesbased on On-Line Analytical Processing (OLAP), a proven database analysis technology thathas been applied to various business areas. This approach automates data processing for engineeringchange analysis from product databases that follow an international standard for productdata management (PDM), and enables analysts to analyze various aspects of engineeringchanges with its OLAP operations. The study consists of modeling a standard PDM databaseand a multidimensional data model for engineering change analysis, implementing the standardand multidimensional models with PDM and data cube systems and applying the implementeddata cube to core functions of engineering change management, the evaluation and propagationof engineering changes.
