The use of supervised pattern recognition technologies for automation in the manufacturing environment requires the development of systems that are easy to train and use. In general, these systems attempt to emulate an inspection or measurement function typically performed by a manufacturing engineer or technician. This paper describes a self-optimizing classification system for automatic decis...

the main purpose of this paper is to examine the convergence of price-levels of tradable goods in comparison to that of services (non-tradable) under the free trade among iranian provinces over 2007- 2012. this comparison has been achieved by applying the pair-wise approach which has been recently developed by pesaran (2005). in this approach, the time series models (adf, df-gls and kpss unit r...

In this study we discuss about an application of fuzzy graph isomorphism. If we look two unequal fuzzy matrices on undirected fuzzy graphs, we cannot say either the fuzzy graphs of theses fuzzy matrices are isomorphic or not isomorphic. It is because two fuzzy matrices may look different even if the fuzzy graphs are isomorphic. In this study, by using the algorithm for fuzzy graph isomorphism i...

Abstract Purpose of this paper: The objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (TOPSIS) approach to evaluate the most suitable RFID-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. Design/methodology/approach: R...

Path algebras are additively idempotent semirings and generalize Boolean algebras, fuzzy algebras, distributive lattices and inclines. Thus the Boolean matrices, the fuzzy matrices, the lattice matrices and the incline matrices are prototypical examples of matrices over path algebras. In this paper, generalized fuzzy matrices are considered as matrices over path algebras. Compositions of genera...

The pair-wise variability index has become a useful and widely used tool for comparing syllable timing of speech. In this paper we present an improved pair-wise variability index based on median instead of means that can more strongly amplify and reveal the differences in the timing characteristics of two datasets. Further, it places less stringent requirements on the pre-processing of the meas...

in this paper, some elementary operations on triangular fuzzynumbers (tfns) are defined. we also define some operations on triangularfuzzy matrices (tfms) such as trace and triangular fuzzy determinant(tfd). using elementary operations, some important properties of tfms arepresented. the concept of adjoints on tfm is discussed and some of theirproperties are. some special types of tfms (e.g. pu...

Paired comparison is an expert based judgment estimation technique. The method reduces individual judgment errors by requiring multiple pair-wise comparisons of relative sizes. Observations made in an academic environment shows that paired comparison produces more consistent results across estimators compared to ad-hoc methods and planning poker. A tool is introduced, which implements a more ef...

in this paper, a novel method for ranking of fuzzy numbers are proposed. in this method, decision maker is defined based on the center of mass at some cuts of a pair of fuzzy numbers in discreet version and center of mass on all of cuts of a pair of fuzzy numbers in continuous version. our method can rank more than two fuzzy numbers simultaneously. also, some properties of methods are described...
