The purpose of research on image quality assessment (IQA) is to find proper methods to measure the quality of images. The subjective evaluation score by HVS is usually used as a standard to be compared with. So, the more similar the measuring process is to HVS, the better the result should be. Motivated by this idea, contourlet transform and singular value decomposition are used in this article to...
The paper proposed a new thought that a multi-agent organization model was designed, which based on cooperative design system network framework and workflow. The system workflow and system architecture were presented. The ant colony optimization (ACO) method which was improved by Bayes was applied to the partner selection. And the principal component analysis (PCA) method was used to evaluate the...
Air combat is the basic operational means of air force. This paper models the air combat effectiveness assessment problem as a multi-criteria decision making (MCDM) problem and proposes a two-step evaluation model, combining the technique of fuzzy AHP (fuzzy analytic hierarchy process) and TOPSIS (technique for order performance by similarity to idea solution). This study applies the fuzzy AHP method...
Supplier selection is the precondition to implement networked manufacturing. There are three kinds of the evaluation indexes: accurate number type, interval number type and fuzzy number type, so the TOPSIS mixed multidimensional decision-making method was used. There are some evaluation factors such as price, quality, network information level, networked condition and credit in supplier selecting...
Partners selection and evaluation is one of the most vital actions of companies in a product design chain. Moreover, decision support is an important part of cooperative design. Selecting the right partner is the assurance of cooperative design. In order to improve reliability and scientificalness, a method of partner evaluation based on BP neural network and PCA is presented. An evaluation index...
