The multislope ski-rental problem is an extension of the classical ski-rental problem, where the player has several options of paying both of a per-time fee and an initial fee, in addition to pure renting and buying options. Damaschke gave a lower bound of 3.62 on the competitive ratio for the case where arbitrary number of options can be offered. In this paper we propose a scheme that for the ...

In this paper, the problem of determining the quality level, lead time for order delivery and price of a product produced by a manufacturer is considered. In this problem the demand for the product is influenced by all three decision variables: price, lead time and quality level. To formulate the demand function, a fuzzy rule base that estimates the demand value based on the three decision vari...

Modern enterprise systems are often process-driven and, thus, rely heavily on process-aware information systems. In such systems, high-level process-models play an important role both for communicating business requirements between domain experts and system experts as well as basis for the system implementation. Since several years, enterprise system need to fulfil an increasing number of the s...

This paper describes the design and evaluation of an extractive summarizer for educational science content called COGENT. COGENT extends MEAD based on strategies elicited from an empirical study with science domain and instructional design experts. COGENT identifies sentences containing pedagogically relevant concepts for a specific science domain. The algorithms pursue a hybrid approach integr...
