AN INTERFACE FOR EXPLORING SPATIAL ALTERNATIVES FOR A CORRIDOR LOCATION PROBLEM
The location of corridors or fights-of-way across a landscape for the purpose of siting a facility such as a power transmission line has been the subject of much research. Many different computerized models have been developed to address this design and layout problem. Any environmental review usually requires that alternative routes be considered. Thus, the value of a model can be measured not only in terms of determining a good solution but in supporting the search for good alternatives as well. Such problems have been posed as multiobjective programming models. This paper presents a novel user interface that is designed to help explore possible alternative corridors. This new interface allows for exploration in terms of both objective space and decision space and could be modified for other spatial decision-making problems as well.
