Abstract :

Ranking DMUs based on individual preferences is an interesting and useful part of decision-making problems. Comparing the weighted sum of the selected number of rank votes, after determining the weights in a selected rank, can be regarded as a common approach to compute the total ranking of alternatives. In actual applications, making the weight of a certain rank zero means that we throw away the corresponding part of the obtained rank voting data. This paper proposes a new model to assess the non-zero weights for each position.
