An optimisation-based decision support methodology is presented for the synthesis of energy supply systems on the conceptual level. Previous work in this field has tended to focus on the generation of the single optimal solution. However, given that mathematical models never perfectly represent...

Local governments and property developers are increasingly seeking robust models for strategic planning of retrofitting residential energy systems. Strategic planning here infers making decisions on technology upgrades at the concept design stage. This represents a problem with many degrees of...

One of the most notable outcomes of Ireland's recent spectacular rise in income was an apparent 140% increase in domestic passenger transport fuel use from 1990 to 2008, at the same time as the car stock has more than doubled in magnitude. However, there have been very few comparisons and...

The implementation of a theoretically sound, two-stage discrete-choice modelling paradigm incorporating probabilistic choice sets is impractical when the number of alternatives is large, which is a typical case in most spatial choice contexts. In the context of residential location choice,...

The discrete choice analysis of residential location choice forms an important part of land use-transport modelling systems but gives rise to a number of significant modelling challenges, one of which is the choice set formation problem. A number of alternative approaches exist to addressing the...

Cycling is often promoted as a means of reducing urban congestion and improving health, social and environmental outcomes. However, the quantification of these potential benefits is not well established. This is due in part to practical difficulties in estimating cycling demand and a lack of...

This paper examines the use and travel impacts of two forms of information and communication technologies (ICTs): mobile telephones and computers. The travel impacts are examined in the context of participation in out-of-home non-maintenance shopping activities over a multiweek period through...

Low-carbon decentralised energy technologies (DETs) have become increasingly popular in recent UK energy policy debates. Many of the technologies involved are well established, but it is only with their increased technical maturity and the imperatives of climate change, energy security and fuel...
