Recently, the performance evaluations of raid manufacturing systems (RMSs) has become more and more crucial, because it is the foundation for investment and implementation of RMSs. However, due to various complex and vague factors involved in RMSs, it is hard to evaluate exactly. To measure a RMS roundly and objectively, a multi-level fuzzy comprehensive evaluation approach based on analytic hierarchy...
This paper analyzes factors that influence the quality of product innovation design, and proposes a method of combining the Analytical Hierarchy Process with Objective Tree method based on fuzzy mathematic theory. Then we put forward a delaminating multilevel fuzzy comprehensive evaluation method for the product innovative design. The square root method is applied to simplify the weight set of fuzzy...
As an important product characteristic, maintainability is recognized as a highly significant factor in the economic success of engineering systems and products. With the rapid development of Virtual Reality (VR) technology, an intuitive, immersive and interactive environment for product maintenance is created in this paper. In order to analyze and evaluate the product maintainability in virtual maintenance...
A grid system is a dynamic and distributed environment which contains mass entities and resources, and is involved in large-scale data exchanges and resource sharing. Thus in grid system, information security is a prime concern. Trust mechanism is a main part of grid security. Taking the fuzziness of behavior trust into consideration, this paper introduces fuzzy theory to grid trust and proposes a...
The method of CFD integrated with CAD is presented to optimize fluid machinery design parameter in the paper. Firstly, the parameter to be optimized is determined. Secondly, the CAD technology is applied to build three-dimensional fluid machinery parameterization models by the parameter in its range, which is used to calculate three-dimensional flow field in the fluid machinery model by CFD software...
Ever since computers and their software were used as essential components in critical systems, the dependability of computer-based systems has been a concern. Dependability of software, a major concern in many computer applications, can be improved through several means. But systematic approaches for its evaluation, which is the prerequisite for dependability control and improvement, do not exist...
In order to overcome the subjective limitation in traditional fuzzy comprehensive evaluation model, a new model based on entropy weight is proposed for evaluating software dependability, and using the entropy weight coefficient method modifies the weight in it. The model reduces the subjective influence, and enhances the evaluation results objectivity. It provides an effective method for software...
Applying DEA with preference method to the fuzzy comprehensive evaluation of logistics enterprises, this paper proposes the model of fuzzy overall evaluation on logistics enterprises based on DEA with preference. The model reflects the evaluation index system of the quality of partners in the logistics alliance, and through fuzzy overall evaluation method, gets the output, then inputs the industrial...
