- ZeitschriftenartikelImplizite Determinierung von Plan-Belegungszeiten(Wirtschaftsinformatik: Vol. 47, No. 2, 2005) Jodlbauer, Herbert; Palmetshofer, Karl; Reitner, SonjaCorrect standard times are needed for logistic operating curves, manufacturing planning and control systems and Advanced Planning Systems (APS) for scheduling, lot-sizing and sequencing. This paper presents a model for calculation of standard times based on the knowledge of the total busy time of a work center and the produced number of items in a fixed time period. The developed method requires little effort in comparison to other methods such as Work-Factor or time observation. It can regularly determine standard times using current confirmation data.

- ZeitschriftenartikelIntegrated Decision Model for Credit Product Outsourcing(Wirtschaftsinformatik: Vol. 47, No. 2, 2005) Holzhäuser, Markus; Lammers, Markus; Schwarze, FelixIntegrated Decision Model for Credit Product Outsourcing The European banking landscape seems to be evolving from a highly vertically integrated banking landscape into a value network of specialized banks. This can also be seen in the credit product industry where consumer credit specialists take over portfolios from other banks. While decision models for IS, operations and production outsourcing are discussed in the literature, we lack a model for credit product outsourcing which reflects the change of risk capital as discussed in the literature about credit sales. In combining these two literature strands, we develop a model to determine whether it is beneficial to internally produce or externally source a credit product.
- ZeitschriftenartikelIntelligente Tourenplanung mit DynaRoute(Wirtschaftsinformatik: Vol. 47, No. 2, 2005) Wendt, Oliver; Stockheim, Tim; Weiss, KilianDue to increasing transportation costs and a rising demand for quality services professional optimization and planning of transport processes becomes a critical success factor for many companies.

- ZeitschriftenartikelKombinatorische Auktionen in der betrieblichen Beschaffung(Wirtschaftsinformatik: Vol. 47, No. 2, 2005) Bichler, Martin; Pikovsky, Alexander; Setzer, ThomasCombinatorial auctions are promising auction formats for industrial and public procurement. Potential advantages of using combinatorial auctions include decreased overall spend, low transaction costs for multi-item negotiations, fairness and market transparency for suppliers, as well as high allocative efficiency. A number of fundamental design considerations are relevant to the application of combinatorial auctions in procurement. In addition, procurement specialists need to consider several domain-specific requirements, such as additional side constraints as well as alternative multidimensional bid types.
- ZeitschriftenartikelStrategien für den digitalen Musikmarkt(Wirtschaftsinformatik: Vol. 47, No. 2, 2005) Buxmann, Peter; Johnscher, Patrick; Strube, Jochen; Pohl, GerritThe recording industry is currently faced with a remarkable decline in revenues and record sales. Paid music services have failed to deliver on their promise of a full-catalog, easy-to-use shopping experience so far, and file sharing platforms are still widely used for obtaining online music. In this context we conducted an empirical study via the Internet with 2.260 participants. The main results are: Neither the installation of copy protection measures nor legal actions taken against users of file sharing platforms seem to be appropriate means to increase sales of CDs and online music.┃Potential consumers’ willingness to pay is distinctly lower than the prices currently set by the available paid music services.┃Our study’s results suggest that a price cut for music downloads would lead to increased sales, thus creating benefits for both suppliers and consumers.
