When renting computing power, fairness and overall performance are important for customers and service providers. However, strict fairness usually results in poor performance. In this paper, we study this trade-off. In our experiments, equal cache partitioning results in 131% higher miss ratios than optimal partitioning. In order to balance fairness and performance, we propose two elastic, or m...

Several disciplines, including artificial intelligence, operations research and many others, study how to make good decisions. In this overview article, we argue that the key to making progress in our research area is to combine their ideas, which often requires serious technical advances to reconcile their different assumptions and methods in a way that results in synergy among them. To illust...

Sketch recognition is the automated recognition of hand-drawn diagrams. When allowing users to sketch as they would naturally, users may draw shapes in an interspersed manner, starting a second shape before finishing the first. In order to provide freedom to draw interspersed shapes, an exponential combination of subshapes must be considered. Because of this, most sketch recognition systems eit...

An effective marketing strategy is a method to identify the customers well. One of methods by performing customer segmentation. This study provided an illustration segmentation based on RFM (Recency, Frequency, Monetary) analysis using machine learning clustering that can be combined with demography, geography, and habit through data warehouse-based business intelligence. The purpose classifyin...

Today, industry is confronted with a fast changing market. Customers demand a high-quality, low price and tailored product. This requires flexible manufacturing systems. At K.U. Leuven, a Manufacturing Execution System (MES) is designed, that allows to adjust execution to quickly changing circumstances. This paper discusses how this MES can cooperate with existing planning systems. A collaborat...

Fast food culture is an emerging trend among the younger generation. The ready availability, taste, low cost, marketing strategies and peer pressure make them popular with children and adolescents. Fast food restaurants are primed to maximize the speed, efficiency and conformity. The menu is kept limited and standardized essentially to minimize the waiting time so that the customers eat quickly...

● Increase in customer engagement through demand response and advanced metering infrastructure (AMI) deployments These applications hold the potential to provide significant benefits to utilities and their customers (Table 1) and quickly realize a positive return on investment (ROI). However, to make these DA applications successful and to achieve the vision of ubiquitous access to near-real-ti...

It seems more and more obvious that we are now living in the era of technology and information. Technological advances have allowed us to generate vast amounts of information of all kinds extremely quickly and, more importantly, store it so that it remains available for subsequent analysis. Accordingly, many large companies and institutions centre a large part of their strategy on the analysis ...
