An optimisation model for prioritising transport projects

The decision of how much to invest in the development of transportation projects is very important. Optimisation tools are commonly used to prioritise investment in transportation networks. The objective of this study was to develop an optimisation model that will prioritise and rank investment in transportation infrastructure. The model was developed using data from the Department of Transport in Ireland. The concept of the ideal solution has been used. This is a multi-objective model, giving more than one optimal solution. The research concludes that weighting assigned by the user to the attributes is crucial in the prioritisation process when the attributes are numerous.
