Global Malmquist Productivity Index based on preference common-weights
Abbasian-Naghneh Salman (Islamic Azad University, Najafabad Branch, Department of mathematics, Najafabad, Iran)
Data Envelopment Analysis is a linear programming technique for assessing the
efficiency and productivity of decision making units (DMUs). Over the last
decade, DEA has gained considerable attention as a managerial tool for
measuring performance. The flexibility in selecting the weights in standard
DEA models deters the comparison among DMUs on a common base. Moreover,
these weights are unsuitable to measure the preferences of a decision maker
(DM). For dealing with these two difficulties simultaneously; we use
preference common weights. This paper uses preference common weights for
time-series evaluations to calculate the global Malmquist productivity index
(MPI) so that the productivity of changes of all DMUs have a common basis
for comparison, and DM’s preference information is incorporated in
calculating global MPI. The Malmquist Productivity Index (MPI) suggests a
convenient way of measuring the productivity change of a given unit between
two consequent time periods.
