As half of the cost of manufacturing multinational corporations come from purchasing, more and more multinational companies recognize the importance of supplier selection. Supplier will directly affect the production cost, quality and delivery, and profits. Therefore, the supplier selection takes a very important role in supply chain management (SCM), further more it directly determines the competition...
TOU price is an effective measure to achieve short-term balance of natural gas market, and a reasonable adjustment of natural gas price is the key to the implementation. Based on related research, some parameters are described through probability distribution, and use the price elasticity to reflect the customers' response to TOU prices, then consider the uniformity of gas using, take Monte-Carlo...
Project selection problem is the core issue of the organizations. In this paper, the method of grey relational analysis for group decision making is applied to select the best project based on multi-granularity 2-tuple linguistic assessment information processing. The subjective judgement of decision makers is represented by means of linguistic variables. The basic linguistic term set is chosen from...
An evaluation model of Gray Relational Analysis with preferences of decision makers based on Characteristics-AHP is built. This model makes fully use of the advantage of gray theory on the fields of performance evaluation for small sample and poor data. Considering preference degree of decision-makers not only makes evaluation result objective and fairness, but also reflects decision-making fact....
Whether enterprise project investment can success or not, the key is how to evaluate various programs. This paper based on grey relational analysis theory, according to relational degree formula calculates the grey relational degree of initial decision matrix with the optimal sequence and the worst separately. On this basis, building the project investment grey comprehensive decision model. Finally,...
Recently, intuitionistic fuzzy sets have been used to build multiple attribute decision making models that can accommodate imprecise information. In this paper, the method of grey related analysis for handling multiple attribute fuzzy decision making problems based on intuitionistic fuzzy sets is presented. The proposed method allows the degrees of membership and non-membership of every alternative...
This paper considers the quality of highway engineering. First, the index system for highway engineering quality evaluation is established. Then, according to the difficult of the quality of highway engineering evaluation, analytical hierarchy model (AHM) and grey mathematic are introduced in the quality of highway engineering. AHM is easy to implement and hierarchical grey analysis theory are good...
Evaluation of teaching is one of the important items of the internal quality assurance system in many higher institutions in China. This paper aims to find a better method to make evaluation on teaching accurate as much as possible. It then provides a grey evaluation model of estimating the indicator system of teaching quality on the basis of the related reference, in which an evaluation methodology...
Multiple attribute decision-making theory under uncertainty is an important part of decision making theory, in this paper, a grey multiple attribute decision-making approach is proposed to study multi-criteria decision-making problems under uncertainty in which criteria values are interval gray numbers. Using grey related analysis as a means to reflect uncertainty in multiple attribute models through...
As a result of the participation of venture capital, the results of scientific research can be easily transferred into commodity quickly. Risk evaluation of venture capital is essential for management decision-making. Based on the AHP method of investment appraisal to determine the risk weights, and based on grey relational analysis method to establish a model to assess the correlation of risk, this...
Risk assessment of project is important basis of project implementation phase risk management countermeasure choice, the core of which is to have qualitative and quantitative analysis to risk factors, as because the uncertainty of project risk factors, there are many risk analysis methods, after comparing the advantages and disadvantages of currently common risk analysis methods of project, this paper...
The method which combines objective weights model with subjective weights model is usually used to weigh the factors to overcome the impacts of decision-makers in the multi-attribute group decision making. Due to the incomplete decision-making information, the weights given by each expert are regarded as the uncertain grey value according to the grey system theory and a combined weights algorithm...
The grey relational analysis is an important branch of grey system theory. It is the foundation of grey clustering, decision-making, and control. The aim of this paper is to further study the properties of algorithms for grey relational analysis. On the basis of analysis on the existing models for grey relational analysis and their properties, this paper first presents the novel definition of affinity...
In real life, because of the limited rationality and lack of information, it is difficult for experts to give accurate judgments. A grey number is such a number whose exactly value is unknown but a range within which the value lies is known. Therefore grey number from grey system theory provides an important and useful tool to help describe the judgments of experts. The typical grey numbers include...
According to the meaning of food security, the index system for China's food security was established and the weight on each index was given by adopting AHP method. This paper made measurement and evaluation on the level of China's food security from 2001 to 2007 by using the AHP-GRA method. The results show that the model which conforms to China's actual situation can be used as a food safety pre-warning...
Evaluating and selecting electric equipment suppliers practically, effectively and reasonably can control the quality of power plant runs. On the basis of analyzing existing appraising method for supplier selection, this article builds up a comprehensive evaluation index system for electric equipment suppliers. AHP for determining criterion's weight is expounded, and then the appraisal and selection...
P2P networks are self-organized and distributed. Efficient nodes risk assessment is one of the key factors for high quality resource exchanging. Most assessment methods based on trust or reputation have some remarkable drawbacks. For example, some methods impose too many restrictions to the samples, and many methods canpsilat identify the malicious recommendations, which result in that the final results...
With the development of economy and urbanization in China, Property Management of residence (PMR) has been playing more and more important role in people's living. Service quality of property management of residence (SQPMR) and how to evaluate it have increasingly been become the focus of social attention as well. However, in real life, people usually use qualitative method to estimate SQPMR. The...
One fundamental issue is target classification and taxis in selecting and striking target, which is the crucial link of combined firepower strike. It is the core problem of winning the victory of combined operation to how to grade the target system. This paper establishes the model of target classification and taxis by using the methodologies of grey decision-making and grey relevancy, and an example...
With the development and advancement of reverse logistics concepts and practice, the evaluation and selection of vendors or partners for the specific function of reverse logistics support becomes more important. This paper firstly analyses the framework of selecting a third-party reverse logistics provider. Next, this paper presents a set of evaluation index system for choosing a third-party reverse...
