Double-pipe counter-flow heat exchangers are considered more suitable for recovery in the transfer industry. Numerous studies have been conducted to develop static tools optimizing operating parameters of exchangers. Using this study, an improved exchanger system will be developed. This is frequently used solve optimization problems and find optimal solutions. The Taguchi method determines crit...

In order to achieve association of carrier industry such as the flow, logistics, capital flow, information flow and improve the connection of infrastructure of two transportation network and communication information network, a new method of evaluating the industry linkage degree based on complexity theory and grey relational degree is provided in this study. The study uses the formula method a...

this study is an attempt to adapt a post-structural approach for the analysis of ‘trans-relational’ episodes prevalent in the study of workplace discourse analysis. to do this, the talk between three employees working at the same office was recorded and analyzed based on a discourse analytic framework. the results of data analysis revealed that five type of relational episodes are frequent in t...

in this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.in the first approach, the equilibrium point of the system is one of the centers of the related membership fu...

A large number of scientific researches and industrial applications commonly suffer from missing data. Some inappropriate techniques of missing value treatment compromise data quality, which detrimentally influences the knowledge discovery. In this paper, we propose a missing data completion method named CBGMI. Firstly, it separates the nonmissing data instances into several clusters by excludi...

nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. to reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

The aim of this paper is to investigate the multiple attribute decision making problems with intuitionistic fuzzy information, in which the information about attribute weights is incompletely known, and the attribute values take the form of intuitionistic fuzzy numbers. In order to get the weight vector of the attribute, we establish an optimization model based on the basic ideal of traditional...

The article presents a method for stock selection from the view of investors who contemplate stocks of a new investment. The AHP (Analytic Hierarchy Process) and Grey Relational Analysis are used as two integral parts of the method. By distilling information from the Judgment matrix, the AHP-GRA method provides a framework to assist investors in analyzing various investment factors, evaluating ...

The aim of this paper is to propose a new multi-sensor target recognition method for solving the problem which the discriminated object has multiple characteristics indexes. The method combines the concept of gray relational analysis (GRA) method and cumulative prospect theory. This method, the characteristic vector matrix was firstly transformed to standardize membership degree decision making...
