An Importance Segregated Multicriteria Optimization Approach for Safety Improvement Project Selection

Choosing an effective and beneficial portfolio for safety improvements implementation under budgetary constraint has always been one of the critical concerns faced by safety agencies. This study proposed an importance segregated multicriteria optimization approach for portfolio selection. The objectives of this approach are 1) Removing the necessary of assigning weights to criteria; 2) Removing the overweighting of the less important criteria; and 3) Minimizing the number of indifferent solutions for the selection of safety agencies. The proposed model is solved by using the constraint method and a case study is completed for demonstrating the usefulness of this approach.
