This paper establishes a post-evaluation index system which can be used to economic benefits post-evaluation on the grid construction projects. According to the features of this project evaluation, the membership functions using to evaluate indexes is formed and the value weight is determined by fuzzy AHP .Then, this method is applied to one project with economic effects evaluation. This method can...
As environment plays an important role in tourism industry, evaluation of tourism environment has become a key part of tourism research. According to the research results at home and abroad, an evaluation index system of tourism environment was established. On the basis of the index system, fuzzy matter-element model was used in evaluating the good or bad of tourism environment. Taking prefecture-level...
Adopt the concept of mutation in Genetic Algorithm to improve Particle Swarm Optimization. The experimental results show tow advantages for the mutation strategies. Firstly, It's workable for the algorithm and the performance was superior to fuzzy PSO and hybrid PSO; Secondly, the agitation strategy was more flexible.
Demand forecast of emergency material is the precondition and foundation of planning emergency material storage strategy. Because of the emergency logistics have the characteristic as follows: sudden, uncertainty, non-conventional, the weak economy, complexity and so on, On the basis of defining the fuzzy condition and fuzzy transfer probability, the paper divides the emergency material demand into...
In recent years, the GMS countries are becoming the hot point of the direct investment. The total volume of investment from Yunnan grows increasingly. But in the meanwhile, the risk of the host country is hindering the investing countries' positivity. The article takes the SME of Yunnan for example, focusing on two sides, one is the forewarning system, another is the management system, and combining...
Combined with the actual situation of China's construction enterprises, based on the growth-medium-sized enterprises evaluation method published by “Research for Small Medium-sized Enterprises Development” joint research projects group, and by using fuzzy clustering analysis to analyze the eight evaluation index systematically which determine the enterprises growth, the sorting of evaluation index...
This paper innovatively proposes a hybrid intelligent system combining fuzzy comprehensive assessment approach and artificial neural network (ANN) that predicts the safety performance of construction site for breaking through the limitations of conventional method. And also inducts the sensibility analysis to discriminate the importance of each index in the assessment index system. The effectiveness...
Customer assessment is very important for product innovation. In this study, the genetic algorithms and fuzzy comprehensive evaluation were used together to analyze the product assessment data. The evaluation made by undergraduates on Master Kong beef instant noodle was used as an example. The research shows that genetic algorithms-based fuzzy comprehensive evaluation is useful in the customer assessment...
The paper analyzes the performance evaluation method in urban emergency logistics. There are always some unexpected events such as natural disasters or calamities which can obstruct the smooth operation of logistics system. In severe events, failed logistics can bring urban regions to chaos. According to the principle of early warning, emergency performance evaluation should be carried out. In this...
Establishment of the optimal objective function is the first and a vital step for optimum design. The foundation pit engineering design is a procedure of multi-objective optimization and multi-objective decision. Some of these objectives can be quantitatively calculated, while others cannot. In order to make a comprehensive analysis of the effects of various factors on the optimum design of foundation...
Most of the inventory models under delay in payments only considered the relationship between the manufacturer and the retailer. However, in practice, the retailer also provides the customer with the credit period to stimulate demand. A three-echelon supply chain system with one manufacturer, one retailer and one customer is presented in this paper. From the perspective of the retailer, fuzzy inventory...
As the principle of enterprises' social responsibility for promoting the protection of labor rights, SA8000 has brought a lot of adverse effects to Chinese export enterprises. In fact the labor condition of Chinese enterprises is indeed worrying. In order to regulate and restrict enterprises' labor conditions in a long-term, and to evaluate and monitor periodically, it is necessary to provide quantitative...
By analyzing the subjects and objects, as well as the targets, we suggest that indicators of performance evaluation should be chosen from two fields, financial and non-financial. Financial indicators are chosen from such types as profitability, solvency, operational capacity and developing capacity, while non-financial indicators are from development and innovation, human resource, industry impact...
This paper presents a summary of recent developments in modeling and optimization of machining processes, focusing on milling operations. With a brief analysis of research on machining parameters selecting system, in this system, a compact selection method based on expert rules, which were obtained from experimental results and extracted from the knowledge of skilled operators, is presented. Expert...
Construction of underground natural gas storage is a large, complex, with multi-objective nature of the projects. Vague Sets Based on Underground Gas Storage solution design are optimized. Examples show that it is convenient and feasible. Proposed single-value data into the data of the formula Vague, Vague sets introduce new similarity measures between the new formula, these two types of formula as...
Scatter is a multi-attribute comprehensive evaluation of the effective method. Referring Scatter comprehensive evaluation model and the fuzzy comprehensive evaluation method, Shenyang equipment manufacturing industry evaluate collaboration supporting system level. They can analyze the evaluation results to identify the weak links, propose to improve the equipment manufacturing collaboration supporting...
This article outlined the ideas of fuzzy comprehensive evaluation, and then researched the innovative ability of undergraduate, by designing innovation ability evaluation index system and evaluation criteria, constructing fuzzy comprehensive evaluation model, and used an empirical analysis to evaluate of student innovation ability; finally put forward ideas for the evaluation of the results.
A capacitated multi-facility Weber problem (CMFWP) is widely used in both theoretic and practical environments. The most studies in this field tackled the problem either by deterministic or probabilistic orientation. Nevertheless, in the real world, some parameters (e.g., demand) are usually imprecise (fuzzy) in nature. Thus, in this paper, we address the CMFWP with fuzzy demands. To solve this problem,...
To achieve the dimensional synthesis of planar four-bar linkages, it established the numerical atlases of coupler rotation-angle operator harmonic characteristic parameters and coupler rotation-angle function's harmonic components firstly. It achieved the basic dimension type of linkages and the mathematical model of coupler path based on complex-vector theory secondly, then acquired the formula of...
For the past decade various kinds of employer evaluation activities have been on the rise, but almost all of them are short of the guidance of scientific and effective employer brand competitiveness evaluation system. Therefore, this essay attempts to develop the employer brand evaluation system by taking consideration of two dimensions: social recognition and employee satisfaction, firstly utilizing...
