Multiple Criteria Decision Making

tom 10

As cancer diseases take nowadays a heavy toll on societies worldwide, extensive research is being conducted to provide more accurate diagnoses and more effective treatments. In particular, Multiobjective Optimization has turned out to be an appropriate and efficient framework for timely and accurate radiotherapy planning. In the paper, we sketch briefly the background of Multiobjective Optimization research to Intensity Modulated Radiation Therapy, and next we present a rudimentary formulation of the problem. We also present a generic methodology we developed for Multiple Criteria Decision Making, and we present preliminary results with it when applied to radiation treatment planning.

Multiple Criteria Decision Making

2013

tom 8

84-100

We present an application of a methodology we developed earlier to capture a decision maker's preferences in multiobjective environments to a notorious problem in the realm of Air Traffic Management, namely the Airport Gate Assignment Problem. The problem has been modelled as an all-integer optimisation problem with two criteria. We have implemented this methodology into the commercial solver CPLEX and also into an Evolutionary Multiobjective Optimisation algorithm and we have solved with them a numerical instance of the Airport Gate Assignment Problem for a couple of decision making scenarios.
