Introducing a new data envelopment analysis method with restricted weights

Traditional data envelopment analysis (DEA) has two weaknesses.It does neither take the decision maker s subjective preferences nor rank the decision making units(DMUs).In this paper we propose a new DEA model with restricted weights by using a piecwise triangular weighing fuzzy analytical hierarchy process(AHP).This model overcomes the mentioned weaknesses.
