Because of the complexity of limitation and realistic decision of decision knowledge, multiple attribute decision making problems with the attribute value often need to characterize fuzzy number. The triangular fuzzy number to describe this kind of ambiguity is very effective and for the project investment selection problem with triangular fuzzy numbers, this study puts forward a new multiple a...

OBJECTIVE To determine the level of managers' propensity for outsourcing the services in hospitals using decision-making matrix. METHODS The applied, cross-sectional study was conducted at three hospitals affiliated to Bandar Abbas University of Medical Sciences, Iran, in 2013, and comprised managers and employees of four service units: radiology, laboratory, nursing, and nutrition services. ...

Decision matrix based methods are perhaps the most popular concept selection approaches used in industry. Although potentially effective and simple to use, they are not without drawbacks. The weighted sum approach that these methods are based on presents serious risks, because it can falsely portray some concepts as being undesirable when in reality they may even be the most desirable. Addition...

By evaluation of the blasting results, a proper blast pattern can be presented. It is, therefore, essential to employ a reliable method to evaluate blastings for the effective control and optimization of the main cycle operations. This paper aims to propose a criterion for evaluating the blasting results such as the fragmentation, muckpile condition, back-break, and fly rock, and to make a poss...

In this paper, a new soft computing group decision method based on the concept of compromise ratio is introduced for determining decision makers (DMs)' weights through the group decision process under uncertainty. In this method, preferences and judgments of the DMs or experts are expressed by linguistic terms for rating the industrial alternatives among selected criteria as well as the relativ...

Application of model base in group decision making that makes up a Group Decision Support System (GDSS) is of paramount importance. Analytic Hierarchy Process (AHP) is the multi-criteria decision making (MCDM) that has been applied in GDSS. In order to be effectively used in GDSS, AHP needs to be customized so that it is more user friendly with ease of used features. In this paper, we propose a...

Guo et al. recently presented a reaction attack against the QC-MDPC McEliece cryptosystem. Their attack is based on the observation that when a bit-flipping decoding algorithm is used in the QC-MDPC McEliece, then there exists a dependence between the secret matrix H and the failure probability of the bit-flipping algorithm. This dependence can be exploited to reveal the matrix H which constitu...

The purpose of this paper is to apply TRIZ for solving the GSC problems in Sobhanoncology pharmaceutical firm. A review of the past papers of TRIZ based methods to GSC problem resolution is presented. The TRIZ contradiction matrix tool which was applied to the specific problem brings many benefits e.g.: being rapid acceleration in solving the problem. Moreover provides repeatability, reliabilit...

We study a decision problem that emerges from the area of spatial reasoning, but that is also of interest to the area of computational algebraic geometry. This decision problem concerns the use of constraint calculi in qualitative spatial reasoning. One such qualitative calculus describes polylines in the plane by means of their double-cross matrix. In such a matrix, the relative position (or o...

One of the most important requirements of developing appropriate strategies for international marketing is correct identification of target markets. Using quantitative techniques and decision making skills will lead to better results regarding the evaluation of marketing strategies. In this study, first we have used internal factor evaluation (IFE) matrix for recognizing and comparing strengths...
