Product Assembly

In order to make people’s lives more convenient and enhance living standards, the composition of a product usually includes more than one component. However, a product is created by the joint endeavor of people from various territories and therefore one of the important considerations is making a product merge into consumers’ daily lives rather than simply fulfilling its functions. There might be conflicts with people’s existing life patterns or existing values, which should be taken into consideration during the manufacturing process. This study is an investigation of the process of assembly by considering the assembly operations and the assembly operating time. By determining the relationship between components, the assembly concept of most components was analyzed. A fuzzy comprehensive evaluation was carried out during the evaluation of the degree of complexity of user operations. Depending on the ranking of membership, the most appropriate assembly was determined and this serves as a reference for designers to select the optimal product assembly. By recording the consumer usage models, the optimal assembly and usage model of product design were also proposed. The goal of this study is to find the balance between assembly evaluation and user usage model by the process in order to allow designers to determine the new assembly concepts that meet consumer usage models. A case study of four bedside stereos was carried out by implementing the proposed approach in order to determine the evaluation principle of assembly. The purpose of this is to enhance the balance between assembly design and user operation complexity for making efficient decisions. A product design can comply with the spirit of concurrent engineering and the quality of a product design can be enhanced.

This paper chose multi-index to provide a comprehensive evaluation model to evaluate the use reliability of CNC machine tools as a single assessment indicator is biased. As the number of evaluation factors is huge and it is difficult to get the exact values, a fuzzy theory is applied. Reliability mathematical model and maintainability mathematical model were established based on failure data selected from filed test and calculated the estimation values of reliability indexes. Subsequently, a fuzzy comprehensive evaluation mathematical model of CNC machine tools was constructed which combined fuzzy with comprehensive evaluation theory. Using this model could evaluate reliability level of CNC machine tools accurately and integrative.

This paper first introduces the relevant content of fuzzy theory system and expounds the relevant knowledge of fuzzy comprehensive evaluation in fuzzy theory. In this paper, an evaluation system for the teaching of environmental art design specialty based on the integration of production, teaching and research is established to provide scientific basis for the exploration and control of the teaching mode, and a fuzzy comprehensive evaluation model is established on the basis of the index system. Through the methods of literature retrieval, real data analysis and expert interview, 14 factors influencing the level of classroom teaching were collected, and questionnaires were distributed to teachers to collect the factor weight data, and these data were sorted out and calculated to obtain the weight indicators at all levels. Through the collection of online teaching evaluation data, the fuzzy evaluation matrix of each level index is calculated, and the matrix is combined with the corresponding weight vector to establish the fuzzy comprehensive evaluation model. Finally, the teaching evaluation results of the integrated mode of production, teaching and research are as follows: 74.8% are excellent, 12.6% are good, 7.1% are medium, and only 5.5% are poor. Through the above results, it can be concluded that the teaching effect of the integration mode of production, teaching and research is excellent.

Complex ability evaluation of university students is an important means of training talents to the related teaching department, and it has a very important role to improve the training quality of university and the quality of teaching. In this paper, by analyzing of the disadvantages of traditional evaluation method, an evaluation model is put forward a kind of based on fuzzy comprehensive evaluation of university student' complex ability, and give the evaluation model of the specific composition and the corresponding algorithm. The model is better than common evaluation tools to weigh the various factors in the case of making information not lossing. It can naturally deal with the initiative and fuzziness of the human mind, so it makes the every student evaluated get an objective and fair evaluation result.

Early Warning Management

The financial market is changing rapidly. Since joining the WTO, our country’s financial companies have faced pressure from dual competition at domestic and abroad. The complex internal and external environment has forced financial enterprise managers to improve risk prevention awareness, early warning and monitoring, so as to responding to emergencies and challenges in the financial market. However, traditional forecasting and analysis methods have problems such as large workload, low efficiency, and low accuracy. Therefore, this article applies intelligent computing to the forecast of financial markets, using related concepts of fuzzy theory and Internet intelligent technology, and proposes to establish a model system for financial enterprise risk early warning management and intelligent real-time monitoring based on fuzzy theory. This article first collected a large amount of data through the literature investigation method, and made a systematic and complete introduction to the related theoretical concepts of fuzzy theory and financial risk early-warning management, has laid a sufficient theoretical foundation for the subsequent exploration of the application of fuzzy theory in financial enterprise risk early warning management and intelligent real-time systems; Then a fuzzy comprehensive evaluation method that combines the analytic hierarchy process and fuzzy evaluation method is proposed, taking a listed company mainly engaged in automobile sales in our province as a case, the company’s financial risk management and modeling experiment of the intelligent real-time system; Finally quoted specific cases again, used the fuzzy comprehensive evaluation method to carry out risk warning and evaluation on the PPP projects of private enterprises in our province, and concluded that the project risk score is between 20-60, which is meet the severe-medium range in the risk level. Research shows that the use of fuzzy theory and modern network technology can make more accurate warnings and assessments of potential and apparent risks of financial enterprises, greatly improving the safety of financial enterprise management and reducing the losses caused by various risks.

Comprehensive Evaluation Model

In the College, performance evaluation system is directly related to the harmonious development of the school. Taking into account the factors in the evaluation system is fuzzy, so this paper uses fuzzy comprehensive evaluation model. But the model is too subjective, so this paper combines neural network and data envelopment analysis method, which ensures that fuzzy comprehensive evaluation model is reasonable and scientific, and good school development and teacher self-interest. The performance assessment process, not only enables the combination of qualitative and quantitative analysis, but also fair and reasonably reflect the achievements of teachers, while this method is easy to use, wide application, and can be well applied in practice.
