A fuzzy matter-element evaluation modeling based on cooperative game weight (FME-CGW) is presented in this paper. Based on cooperative game theory, authors introduce a cooperative game weight which embodying an idea of competition and coordination among different weight methods. Based on the cooperative game weight, employing fuzzy matter-element theory and Hamming approach degree, the authors develop FME-CGW model. The derived model is applied to assess the groundwater resources carrying capacity in Guanzhong plain in Shaanxi province. The results are reasonable and satisfactory by comparing to other methods. The study of this practical example shows that the modeling presented in this paper is a new method with simple algorithm and strong practicability, which can be adopted to analysis various comprehensive evaluation issues.

Selection of material supplier is important to international construction project management, and can bring impacts on the project's quality, schedule and cost. Considering the features of international construction projects, we built a selection decision-making evaluation index system. Triangular fuzzy AHP (Analysis of Hierarchy Process) method was used to calculate the weights of evaluation index. Using the medium value of triangular fuzzy number, a simple and convenient method was developed to test the consistency of judgment matrix. Base on calculating the weights of evaluation index, a fuzzy matter-element model was proposed to calculate the comprehensive evaluation values. Taking the selection of cement suppliers of the Congo (Brazzaville) National Road One Second Project as an example, the Euclid closeness of alternative suppliers was calculated to determine the ranking order of alternatives.

Abstract Aiming at the problem of transformer condition evaluation, a comprehensive evaluation system for transformer noise is constructed according to the mechanism of transformer noise generation and propagation. Using matter-element theory and AHP, a state analysis method for transformer noise evaluation based on AHP matter-element model is proposed. The case analysis proves that the method is feasible for non-contact evaluation of transformer faults, and can accurately evaluate the state of the transformer, providing guidance for the operation and maintenance of the transformer.

Background: The gear shifting comfort of tractors is affected by various factors, which make it extremely difficult to accurately and quantitatively describe the handling comfort through objective physical quantities. However, the calculation and evaluation process of the index of manipulation comfort mostly involves the operation of matrix form, and the numerical operation is one of the powerful core functions of MATLAB. Objective: This study aims to take the gear shifting process of tractors as the research object and uses MATLAB /GUI toolbox to develop the shifting comfort evaluation system, thereby improving the gear shifting comfort. Methods: The procedures of holistic assessment, element subdivision, and detailed tracking were adopted as the analysis method. Thus, the operation process was divided into four action units, including pedal free travel, separation travel, gear change, and joint travel, according to the concept of “differentiation” and manipulation behavior. Based on the matter-element model, the process of clutch operation was described by coupling of action elements. The closeness between the actual model and the target model was used to measure the degree of handling comfort. Then, the results were compared with those of the multi-index comprehensive evaluation. Results: It was shown that the separation travel has the greatest influence on the handling comfort. Taking vehicle 1 as an example, the matter-element analysis model provided the overall comfort value of the carrier (0.8359), which is close to the value of the multi-index comprehensive evaluation (0.8156). Moreover, the evaluation results presented the score of each action unit, which could directly reflect the action units with the lowest level of comfort. The evaluation results of matter-element model can not only reflect the handling comfort of different components, but also locate the negative aspects of the whole operation. Conclusion: This method is effective in overcoming the ambiguity of the concept of comfort and the generality of overall evaluation as well as avoiding the uncertainty of subjective evaluation.
