Multicriteria Decision Making in Civil Engineering
The current research interest focuses on applications of multi criteria decision making techniques to solve civil engineering problems. Possible topics included engineering design, prioritization and evaluation of public measures, classification problems, etc. Some research topics require knowledge and cooperation from multi-disciplinary fields. Example of research ~ being conducted includes highway corridor planning, prioritization of highway accident reduction measures, landslide/seismic hazard zonation, seismic resistance and maintenance prioritization of existing buildings. Techniques such as the Analytic Network Process (ANP) and Fuzzy Decision Making Methods are used to solve the multicriteria decision making problems.
Highway Design Optimization
Highway design is the complex process that involves many constrains and objectives to be achieved. The conventional design method is manual. Therefore the number of alternatives is limited by the choices of the designer. It is also time and cost consuming to generate many alternatives by the manual design. The research aims to apply some heuristic techniques such as Genetic Algorithm (GA) and Ant Colony Optimization (ACO) to solve the highway design optimization problem within the Geographic Information System (GIS) environment.
