We describe how a generic multi-period optimization-based decision support system can be used for strategic and operational planning in a company whose processes can be described in terms of five fundamental elements: Materials, Facilities, Activities, Times and Storage-Areas. We discuss the issues of interface design, data reporting and updating, and production and profit planning. We also com...

The paper is based on the authors’ work for the HiTrans Interreg III-project (Nielsen, Lange et al. 2005), recent work on a good practice guide for public transport system design in rural and small town regions for the Norwegian Ministry of Transport and Communications (Nielsen and Lange 2008), earlier literature studies and consultancy work for various public transport bodies in Norway. The id...

Understanding and preventing overrtting is a very important issue in artiicial neural network design, implementation, and application. Weigend (1994) reports that the presence and absence of overrtting in neural networks depends on how the testing error is measured, and that there is no overrtting in terms of the classiication error (symbolic-level errors). In this paper, we show that, in terms...

Stochastics affects the optimal design of a network. This paper examines the single-source single-commodity stochastic network design problem. We characterize the optimal designs under demand uncertainty and compare with the deterministic counterparts to outline the basic structural differences. We do this partly as a basis for developing better algorithms than are available today, partly to si...
