Measuring efficiency by a single price system

Article Abstract:

A multi-criteria model that measures the relative levels of efficiency for a set of alternatives is proposed. Two steps are involved in the model: the classification of the alternatives as inefficient and non-inefficient and the identification of a single price system for the non-inefficient alternatives. In contrast to Data Envelopment Analysis (DEA), the proposed model offers objective determination of the relative efficiency level for every alternative by a single price system.

Reducing the number of linear programs needed for solving the nucleolus problem of n-person game theory

Article Abstract:

The number of linear programs needed for solving the nucleolus problem of an n-person game theory can be reduced through the use of an algorithm proposed by Behringer. The Behringer procedure is significantly better than an earlier procedure proposed by Sankaran. The Behringer approach has smaller linear programs due to its smaller number of constraints. This leads to a more efficient computation of the nucleolus.
