An enhanced approach to the ranked voting system
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 of the improved model is to decrease the effect of inefficient candidates on the efficiency of the efficient candidates. The advantages of the proposed enhancements are illustrated by an example.
