Evaluation of performance and productivity is among the fundamental concepts inmanagement. In order to achieve their goals, organizations must evaluate theirperformance. One of the important stages of performance appraisal is evaluation oforganization’s efficiency. Banks, financial and credit institutions are among the mostimportant organizations of every economic system, because every activity...

The use of Data Envelopment Analysis (DEA) in many fields is based on total flexibility of the weights. However, the problem of allowing total flexibility of the weights is that the values of the weights obtained by solving the unrestricted DEA program are often in contradiction to prior views or additional available information. Also, many applications of DEA assume complete discretionary of d...

Keywords: Data envelopment analysis Target unit Undesirable output Multiple objective linear programming Minimax method a b s t r a c t Data Envelopment Analysis (DEA) is a mathematical programming technique for identifying efficient Decision Making Units (DMUs) with multiple inputs and multiple outputs. DEA provides a technical efficiency score for each DMU, a technical efficiency reference se...

Annually million tons of freight and mail are being transported through US airports. The air freight transportation services reportedly result in millions of jobs, activities and dollars which in effect stimulate economic development of regions and the nation as a whole. Beyond passengers and aircraft movements, freight volume nowadays is another major target of opportunity for an airport manag...

Cross efficiency is one of the useful methods for ranking of decision making units (DMUs) in data envelopment analysis (DEA). Since the optimal solutions of inputs and outputs weights are not unique so the selection of them are not simple and the ranks of DMUs can be changed by the difference weights. Thus, in this paper, we introduce a method for ranking of DMUs which does not have a unique pr...

Because port operations have rapidly been extending, air pollution resulted from ports has increased and become a persistent concern for environmentalist policy makers. The objective of this paper is to measure the environmental efficiency in Korea. main characteristic assessment problem that undesirable output carbon dioxide (CO2) emissions exogenous fixed input terminal area should concurrent...

Frequently undesirable outputs are produced together with desirable. This joint production of bad and good outputs in connection with environmental decision models is the subject of this paper. Recently Haynes, Ratick, Bowen and Cummings-Saxton (1993) addressed the same subject matter. They observed that: "... input resources, including the chemicals of concern, produce as joint products the sa...
