In terms of land use competition, bioenergy is often subject to controversial discussions. This paper presents a study, which addresses the scope of geographic discrete biomass growth, optimal bio-energy plant locations, and related biomass supply areas. In a first step, annual biomass growth is...

The level of service on public transit routes is very much affected by the frequency and vehicle capacity. The combined values of these variables contribute to the costs associated with route operations as well as the costs associated with passenger comfort, such as waiting and overcrowding. The...

Electricity market models, implemented as dynamic programming problems, have been applied widely to identify possible pathways towards a cost-optimal and low carbon electricity system. However, the joint optimization of generation and transmission remains challenging, mainly due to the fact that...

Structural changes in the European natural gas market such as liberalization, increasing demand, and growing import dependency have triggered new attempts to model this market accurately. This paper presents a model of the European natural gas supply, GASMOD, which is structured as a...
