Construction prequalification using data envelopment analysis

Prequalification of Construction Contractor using a FAHP

Analytical hierarchy process (AHP) as multiple criteria decision making tools can be used in the problems with spatial nature like selection of construction contractor. In this study the application of AHP and its weakness and strength and ultimately the fuzzy modified analytical hierarchy process (FAHP) is proposed after the concept of fuzziness, uncertainty and vagueness. A triangular fuzzy u...

Efficient location by using data envelopment analysis

So far, many types of location models have been developed to find optimal spatial patterns according to different spatial metrics such as cost, coverage and availability.  The initial focus of these models is on the location availability of service providers and demand estimates, and some of these models are within the framework of multi-objective programming models.  After the advent of scienc...

Failure Mode and Effects Analysis Using Data Envelopment Analysis

Benefit-cost analysis using data envelopment analysis

Benefit-cost analysis is required by law and regulation throughout the federal government. Robert Dorfman (1996) declares “Three prominent shortcomings of benefit-cost analysis as currently practiced are (1) it does not identify the population segments that the proposed measure benefits or harms (2) it attempts to reduce all comparisons to a single dimension, generally dollars and cents and (3)...

Measuring Eeciency Using Data Envelopment Analysis Measuring Eeciency Using Data Envelopment Analysis

Data Envelopment Analysis (DEA) is a management tool aimed to determine relative eeciency of independent decision making units. Each unit is fully characterized by a set of incommensurable input and output values. This technique is able, by solving linear programming problems, to discriminate between eecient and ineecient units and to provide targets for the ineecient units. The work of the aut...
