Design and Implementation of Data Warehouse for Workshop Assistant Decision-making

Zhang Cuilin1,Wang Rui2,Sun Qiang3,Wang Junqiang3(1Department of Economy and Management,Xi′an Aerotechnical College,Xi′an 710077;2Software Technology Institute,Dalian Jiaotong University,Dalian 116028;3Key Laboratory of Contemporary Design and Integrated Manufacturing Technology(Northwestern Polytechnical University),Ministry of Education,Xi′an 710072)  
First,the function model of workshop assisted decision-making data warehouse(DW) is analyzed based on the requirements of the workshop decision level.Then,the dimension models of four data marts(DM) for manufacturing process,tools,materials and semi-finished products are established.Finally,the online analytical processing(OLAP) method based on BOM(bill of materials) tree is presented.The finished data warehouse has been successfully used in a workshop decision support system,which shows that the design of the workshop assistant decision-making data warehouse is feasible and effective.
