With the aim of getting more accurate and more reliable stock price predicted results, this paper proposes an effective method which is fuzzy rough set and data mining technology. Firstly, stock prices were classified to some groups according to their different time attribute by using fuzzy set and rough set means. Then we calculated truth values of these groups respectively based on the given fuzzy...
Multi-factor of regional social relates to the landscape pattern, Model can simulate the drive mechanism can result by computer simulation . This paper inferred the forecast model of fuzzy weight Markov chain. The new model which is called FWMC to predict the future, combining the character of landscape and the theory of Markov chain, value of cultivated land demand in land use planning. Factors to...
As a branch of Group Decision-Making Method, Grade division plays an important role in many applications such as hazard assessment, quality evaluation, and performance inspection and so on. At present, the most popular grade division method is fuzzy comprehensive evaluation, which determines the decision objects' grade through analysis of evaluation vector. One problem with this approach is that it...
To improve the intelligibility and efficiency of knowledge expression for the land evaluation, a land evaluation method combining simplified fuzzy classification association rules with fuzzy decision is proposed in this paper. To reduce the complexity of the land evaluation models and improve the efficiency and intelligibility of fuzzy classification association rules further, an algorithm to eliminate...
In order to evaluate water resources capacity, a new assessment model based on cloud theory is proposed. Considering the fuzzy feature in assessment, evaluation model based on variable fuzzy sets that can consider the good and bad characters of indexes is established. The method is developed to evaluate water resources carrying capacity in Taohe basin, and the results show that new evaluation methods...
Evaluating the process of university students' elearning scientifically is full of academic and practical significance. The thesis constructs an evaluating indicator system on the process of university students' e-learning based on the learning attitude, communication and cooperation as well as resources used. It also establishes a multi-level fuzzy comprehensive evaluating model by applying the fuzzy-math...
On base of analyzing the situation of recycling economy of coal enterprises and establishing the principle of indication system, an evaluation-index system was established, which included four levels structure (economy development, resource utilization, social development and recycling system) and twenty-two indications. According to comparing all kinds of methods of recycling economy, and considering...
To meet the requirements for being geared to the international standards and to meet the demand for self-development of an enterprise, it becomes more and more common for an enterprise to execute EPC projects. The EPC model compares with the traditional contract model, the risk of general contactor is the biggest undoubtedly. Through the analysis of the EPC model to determine the risk source and loss...
SPC is the actual implementer of PFI project, but SPC itself usually has no ability of development. It will make widely use of various agents in the process of project development, which has greatly increased the complexity of implementation of project. To evaluate the implementation process of project by phase and real-time can become effective tool of SPC to help it realize the project well. From...
Agility is the inevitable trend of supply chain and management. Agile supply chain forces the enterprise to adapt to the unpredictable market demand, takes the fast restructuring of dynamic alliance as the basic point, promotes the cooperation and the production mode between enterprises, and enhances enterprise's integrated management and economic efficiency. As a key component of the supply chain...
Based on the present situation of railway design quality, an evaluation index system of railway design quality is setup, and multiple fuzzy comprehensive evaluation method is used to evaluate railway design quality. Then, an empirical analysis is carried on a railway. The results showed that the index system and evaluation method has a strong feasibility and operability. It will be widely popularized...
One of the most important phases in business-to-business-based electronic construction bid is the process of bidding decision-making module whose operating optimization is considered to be the foundation of implementing the integration of B2B-based bid mode. Strategies facilitating the optimization of E-bidding are demonstrated in this paper: in order to utilize the efficiency and effectiveness both...
Researchers have proposed a lot of detecting and testing methods about change points. While in the real case, it shows that the structure change of a time series was changed gradually, that is the change points has illustrated senses of fuzziness. This concept is important in fitting different models to different regimes of the data regarding economic interpretation of the data during that regime...
Circular economy, as an advanced development mode for harmonizing the Problems among resource, environment and economy, is destined to be the choice for coal concerned enterprises to explore new industrial way and keep on developing. The paper eliminated the redundant data in index membership for object classification by defining distinguishable weight and extracted valid values to compute object...
The assessment of human resource performance objectively, thoroughly, and reasonably is critical to choosing managerial personnel suited for organizational development. Therefore, an efficient tool should be able to deal with various employees' data and assist managers to make decision and strategic plan. As an effect mathematic tool to deal with the vagueness and uncertainty, fuzzy data mining is...
In recent decade, DRM (digital rights management) has focused on security techniques for solving the issues as the malicious copy, free dissemination and unrestricted abuse of digital contents or assets. Whereas some increasingly enhanced security policies, which were implemented at contents provider-side or user-side, have not brought about optimal utilities for participants in the contents value...
Supply chain flexibility assessment (SCFA) has been considered as a major determinant of competitiveness in world class manufacturing. The environmental issues as well as speed, variety, flexibility and integration in production line come along with customer relationship and mass customization concept should come to light in today's research studies. To achieve competitive edge, companies must align...
Though the price of M&A has already been studied based on classical NPV model, which is not adaptable for real uncertain situation. This paper presents a new approach of measuring the target enterprise value of M&A, consisting of two parts, one is measured by NPV model and another is measured by real options model, which can be integrated to calculate the target enterprise by introducing synergy...
Architectural design (AD) proposals selection is one of the most crucial procedures before the final construction of a project. To make decisions, the jury members need to assess the design proposals considering various criteria, such as function, appearance, sustainability, context, economics, and so on. A model based on fuzzy analytic hierarchy process (FAHP) is proposed to select the most appropriate...
Based on the competency evaluation theory, this paper analyzes R&D staff' s core competency by using Question-and-Answer Survey and Behavioral Event Interviewing. The author not only establishes evaluation index system of R&D staff' s core competency, but also uses fuzzy mathematics to set the fuzzy comprehensive evaluation model of calculating R&D staff' s core competency. we This model...
