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...

The development of software products in general and educational games in particular is a very demanding process involving costly resources for long periods of time. Evaluating its quality throughout the development lifecycle contributes to the early identification of imperfections and to improved efficiency. In this paper we discuss a set of quality criteria and a method to assess the quality o...

Methods We retrospectively evaluated the CMR scans of 294 patients referred for ARVC between 2005 and 2010 and determined the presence or absence of major and minor CMR criteria using the original and the revised TFC. Previously, major and minor abnormalities were identified by the presence of RV dilatation (global or segmental), RV micro-aneurysm, or regional hypokinesis. The revised criteria ...

Abstract The quantitative multiple criteria decision making methods are practical to use in decision support systems. In this paper we analyses the quantitative multiple criteria decision making methods and sensitivity analysis methods usage in decision support systems. Both species of these methods are strongly mathematically based. We take notice of sensitivity of these methods to initial dat...

Disposal of health-care waste (HCW) is considered as an important environmental problem especially in large cities. Multiple criteria decision making (MCDM) techniques are apt to deal with quantitative and qualitative considerations of the health-care waste management (HCWM) problems. This research proposes a fuzzy multi-criteria group decision making approach with a multilevel hierarchical str...

This paper suggests ranking alternatives under fuzzy MCDM (multiple criteria decision making) via an centroid based ranking approach, where criteria are classified to benefit qualitative, benefit quantitative and cost quantitative ones. The ratings of alternatives versus qualitative criteria and the importance weights of all criteria are assessed in linguistic values represented by fuzzy number...
