This paper provides enhancements to a Data Envelopment Analysis (DEA) and Assurance Region (AR) model for a ranked voting system. A transformation of the given data reduces the number of constraints on the weights in the model, thus making it more effective and easier to solve. Another advantage...

Weighted additive models are well known for dealing with multiple criteria decision making problems. Fuzzy goal programming is a branch of multiple criteria decision making which has been applied to solve real life problems. Several weighted additive models are introduced to handle fuzzy goal...

This paper focuses on the design, development and implementation of new Pareto efficiency detection and restoration techniques for integer goal programming. The design of the algorithms and their implementation issues within (an otherwise continuous) goal programming system are detailed. The...
