Abstract
Rapid improvements in the hardware and software for geographic information system (GIS) have enhanced its potential for solving various types of engineering and management problems. This study develops a multiobjective, mixed-integer programming model for collection vehicle routing and scheduling for solid waste management systems synthesized within a GIS environment. The integration of the mathematical programming model and the GIS were demonstrated through application to a specific site in Taiwan. The proposed interactive design procedure using GIS allows a decision maker to analyze many waste collection alternatives before selecting a final operational scenario. Such a system also has potential application in many other environmental planning and management problems.
