this study provides an alternative approach to decisionmaking and its application in selecting the best attack helicopter. in thisway, principal component analysis (pca) is used to find the weights ofthe criteria after identifying the effective criteria for the evaluation andselection of attack helicopters. these weights, then, applied in theobjective function of goal programming (gp) model. fi...

abstract: performance evaluation models of information and communication technology (ict) sectors have been already considered with many perspectives of ict management. since ict has two distinct aspects of usefulness and harmfulness for the environment, therefore, this research with regard to the new dimension named environment, is going to present a new performance evaluation model with the a...

the increasing reliance on information gathered from the web and other internet technologies raise the issue of trust. through the development of semantic web, one major difficulty is that, by its very nature, the semantic web is a large, uncensored system to which anyone may contribute. this raises the question of how much credence to give each resource. each user knows the trustworthiness of ...

This paper reviews methods to evaluate the performance of air quality models, which are tools that predict the fate of gases and aerosols upon their release into the atmosphere. Because of the large economic, public health, and environmental impacts often associated with the use of air quality model results, it is important that these models be properly evaluated. A comprehensive model evaluati...

strategic performance evaluation of an organization within the industry environment is one of the basic and most important prerequisites of organizational improvement plans. in today’s knowledge-based economy and dynamic environment, it is essential for universities as the centers of education, knowledge creation and knowledge worker evolvement. till now, variant models with different approache...

Cross efficiency evaluation was developed as an extension of DEA. But the traditional DEA models usually have alternative optimal solutions and, as a result, cross efficiency scores may not be unique. It is recommended that without changing the DEA efficiency scores, the secondary goal should be introduced for optimization of the inputs/outputs weights.  Several reports evaluated the perfo...
