To facilitate uncertain internet opinion emergency decision involved with multiple fuzzy index values, we design a new prewarning decision system mechanism for uncertain internet opinion emergency based on case reasoning and grey relational analysis. Through the invented software in recent patents in data mining areas we first collect the internet opinion and detect the emergency data. Then by ...

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 current study presents an investigation on the optimization of injection molding parameters of HDPE/TiO₂ nanocomposites using grey relational analysis with the Taguchi method. Four control factors, including filler concentration (i.e., TiO₂), barrel temperature, residence time and holding time, were chosen at three different levels of each. Mechanical properties, such as yield strength, You...

To help the client to select a competent agent construction enterprise (ACE), this study aims to investigate the selection standards by using the Fuzzy Analytic Hierarchy Process (FAHP) and build an evaluation mathematical model with Grey Relational Analysis (GRA). According to the outputs of literature review, four orderly levels are established within the model, taking the consideration of va...

The objective of the paper is to present neutrosophic soft multi attribute group decision making based on grey relational analysis involving multiple decision makers. The concept of neutrosophic soft sets is derived from the hybridization of the concepts of neutrosophic set and soft set. In the decision making process, the decision makers offer the rating of alternatives with respect to the par...

– AbstractIn a heterogeneous wireless network, multiple networks are available to provide end to end mobility and service to mobile users. So in heterogeneous wireless network, selection of the optimal network becomes an important task, which is a key technology to realize fair resource allocation and load balancing for converged multi-radio heterogeneous networks. In this paper, we combine the...

The paper describes the multi-objective optimization of hole sinking electrical discharge micromachining (HSEDMM) process considering material removal rate (MRR), tool wear rate (TWR), and hole taper (Ta) as objectives simultaneously. The micromachining parameters considered in the present work are gap voltage and capacitance of capacitor. Eighteen set of experiments are conducted as per L18 or...

This paper presents a novel warning decision model for uncertain network public sentiment emergency of which index assessments are provided as uncertain values. First, a weighted grey relational formula is proposed to compute the comprehensive grey relational degree between the unknown network public sentiment emergency and each original emergency case. According to the evaluated grey relation ...
