This paper considered complex weapon system reliability optimization allocation. Firstly, according to the restrictions like cost and quality of the system, this paper constructed the optimization model of reliability redundancy allocation of weapon system with the system reliability as objective function. Secondly, this paper proposed a numerical solving algorithm based on heuristic method. This kind of algorithm improved the reliability of subsystems at all levels so that the entire system reliability became maximum. This paper did example analysis about reliability optimization allocation of antiaircraft weapon system.

IT Project selection is a multi-criteria decision-making (MCDM) problem. The key process of IT project selection is the assessment criteria framework establishment and criteria weight evaluation. Several criteria should be included into the judging system, and the complexity of multi-criteria judgment could even increase if relationships among selection criteria are taken into consideration. A method named fuzzy analytic network process (FANP) is proposed to tackle with the relationships of criteria and the uncertainty of them. A network structure of criteria is developed according to ANP method first, and then fuzzy method is used to evaluate the interdependent importance between criteria. After the weight determination of relative criteria, project selection result could be clear. At the end, an example is given to explain the usage and availability of this method.

In the present study, we analyzed the origin of pressure fluctuation of ceramic filter during recoiling washing process and found that reducing such pressure fluctuation necessitates the use of an accumulator or the structure improvement of distribution valve. By employing the TT-12 type of ceramic filter machine as an example, according to known conditions and through calculation and analysis, we determined the air pressure and accumulator volume and chose the NXQA-16/10-L-A accumulator. By employing the TT-45 type of ceramic filter machine as an example, changing the internal structure of the distribution valve from round to waist, the backwash time was prolonged. With the use of the two kinds of methods, we demonstrated that the pressure fluctuation was reduced to be within 0.02 MPa, which satisfied the requirements for recoiling washing.

Multi-level product data visualization plays an important role for protecting the proprietary intellectual property and improving the collaborative efficiency in collaborative product development chain. Different with the common bottom-up quad mesh generation procedure, this paper develops a top-down approach for multi-level product data visualization. With the help of the generated multi-level quad meshes, the problem of how much of a product visible to viewing users is reduced to the task of which level quad mesh to select. An example is given to demonstrate the validity of this method.

In this paper, we first introduced SKIP mode decision at early stage. And then, compared the H.264 and AVS-M fast intra mode decision. For H.264, by making use of the edge direction histogram, the number of mode combinations for luma and chroma blocks in a MB that take part in RDO calculation has been reduced significantly from 592 to as low as 132. For AVS-M, we got a statistical order list of the best mode based on the Most_Probable_Mode. By using this list, we get an order to evaluate if a mode is the best mode or not. Experimental results show that these methods speed up the encoding process without loss of coding PSNR and bitrate efficiency.

Rough set theory generalizes the classical set theory by allowing an alternative to formulate set with imprecise boundaries. It has been demonstrated to be useful in many fields such as knowledge discovery, decision analysis, data mining, etc. In this paper, we discuss the main tolerance-based VPRS models. Further, the relations of tolerance-based VPRS models are also investigated. Through the relations of different models, one can obtain the generalized model based on tolerance-based VPRS models. Numerical examples are employed to substantiate the conceptual arguments.
