The object of this thesis is the discussion of the institutional arrangements of the rail infrastructure. First the … incentives created by different arrangements are discussed. An analysis of the effects on operation of the rail infrastructure …

thesis, we combine fundamental electricity market models with stochastic dynamic programming to evaluate power plant … investments under uncertainty. The application of interpolation-based stochastic dynamic programming and approximate dynamic … programming allows us to consider a greater variety of stochastic fuel and carbon price scenarios compared to other approaches. …

pollutant emissions from locomotive operation. All new locomotives must meet strict standards when they are built, and existing … locomotives must comply when they are rebuilt. Emissions can be reduced either by adjusting combustion parameters, which incurs a …

Maintenance of locomotives is the main function of Bellville Locomotive Traction Depot in the Western Cape. Therefore … increased frequency of maintenance through a case study relating to 35-class locomotives. The abnonnal increased frequency of … wheel change and inter-bogie control repairs on 35-class diesel locomotives is investigated.A research survey was adopted …

approximate dynamic programming (ADP). These policies lay a methodological foundation for solving large-scale sequential decision … problems and provide a framework for developing dynamic routing policies.Our dynamic rollout policies for the VRPSDL …-time implementation, thereby providing a mechanism to make high-quality, dynamic routing decisions for large-scale operations.Finally, we …

Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory … adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed …. Recently, Bushehri (2003) showed how a generalized dynamic Rotterdam model could be derived from the neoclassical intertemporal …
