Nowadays, the U.S. pharmaceutical industry has been under thorough scrutiny. Popular press claims of intensive marketing activities that go beyond R&D, the strong increase of me-too drugs, and, at the same time, the high industry profitability have contributed to public skepticism. Despite this...

Many product innovation studies have described key determinants that should lead to successful incremental product innovation. Despite numerous studies suggesting how incremental product innovation should be successfully undertaken, many firms still struggle with this type of innovation. In this...

There has been much debate in the management sciences in general and the field of information systems in particular over the tradeoffs between rigor and relevance. Since it is viewed as a tradeoff, most of those debating the issues take up position on one side or the other. On the one hand,...

An increasing number of commercial companies are using online reverse auctions for their sourcing activities. In reverse auctions, multiple suppliers bid for a contract from a buyer for selling goods and/or services. Usually, the buyer has to procure multiple items, which are typically divided...

We present new lower bounds for the Capacitated Lot Sizing Problem with Set Up Times. We improve the lower bound obtained by the textbook Dantzig-Wolfe decomposition where the capacity constraints are the linking constraints. In our approach, Dantzig-Wolfe decomposition is applied to the network...

In a recent paper, Fisher et al. (2001) present a method tomitigate end-effects in lot sizing by including a valuation term for end-of-horizon inventory in the objective function of the short-horizon model. Computational tests show that the proposed method outperforms the Wagner-Whitin algorithm...

A stochastic inventory routing problem (SIRP) is typically the combination of stochastic inventory control problems and NP-hard vehicle routing problems, for a depot to determine delivery volumes to its customers in each period, and vehicle routes to distribute the delivery volumes. This paper...

This paper explores how standardization education can be implemented at the national level. Previous studies form the main source for the paper. This research shows that implementation of standardization in the national education system requires policy at the national level, a long term...

Advances in computational methods have led, in the world of financial services, to huge databases of client and market information. In the past decade, various computational intelligence (CI) techniques have been applied in mining this data for obtaining knowledge and in-depth information about...
