Multi-Objective Decision Making for Land Use Planning with Ordered Weighted Averaging Method

Multi-objective decision making is common in environmental engineering management. A compromise solution to the multi-objective problems under conditions of conflicting objectives with GIS-based Ordered Weighted Averaging (OWA) method is investigated. In some instances, decisions may be based on a single criterion, but commonly several criteria are required to define the decision set. Ordered Weighted Averaging (OWA) is a relatively new Multi-Criteria Evaluation (MCE) method. In GIS-based OWA method, both criteria weights and order weights are considered. Calculation method of order weights based on Orness, and construction method of comparison matrix for criteria weights based on analytical hierarchy program (AHP), are introduced; Multi-objective decision making of this method is investigated. As an example, GIS-based OWA method is applied to Tangshan City, and some advice is proposed for engineering design.
