OLAP for Multicriteria Maintenance Scheduling
Walter Cai, David C. Anastasiu, Mingji Xia, Byron J. Gao · DMIN · 2009
Widely used in decision support systems, OLAP (Online Analytical Processing) technology facilitates interactive analysis of multi-dimensional data of varied granularities. In this paper, we demonstrate an interesting application of OLAP in solving multicriteria maintenance scheduling problems. Maintenance scheduling has many important applications, such as maintenance of inverted indexes for search engines and maintenance of extracted structures for unstructured data management systems. We introduce the design and implementation of Scube, an OLAP-based web service that allows users to navigate in a multi-dimensional simulation cube and comprehensively evaluate maintenance schedules. Based on the evaluation, the best trade-off schedule can be selected.1
