	The fuzzy comprehensive evaluation of laser weapon system combat effectiveness (EI CONFERENCE) 会议论文 OAI收割 2012 3rd International Conference on Mechanical, Industrial, and Manufacturing Technologies, MIMT 2012, March 24, 2012 - March 25, 2012, Shenzhen, China Li H.; Guo L. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 To evaluate the laser weapon system's combat effectiveness which is related with so many factors is a very complex issue. In this paper by analyzing the factors which influence the laser weapon system an index system for the laser weapon system comprehensive evaluation of the combat effectiveness is built up. The method of calculating weight the improved analytic hierarchy process is introduced. The evaluation model of improved fuzzy-AHP is established and the feasibility and the validity of the proposed evaluation method is validated through a practical example.

	Efficient rate control technique for CCSDS image encoding (EI CONFERENCE) 会议论文 OAI收割 IEEE 2nd International Conference on Computing, Control and Industrial Engineering, CCIE 2011, August 20, 2011 - August 21, 2011, Wuhan, China Jin L. 收藏 \| 浏览/下载：95/0 \| 提交时间：2013/03/25 For the limitation of data transmission bandwidth and real time transmission demand generally image compression is required to implement the precise and flexible rate control algorithm. Rate control is an important issue in the image compression field. This paper considers the problem of rate allocation to each encoded segment for CCSDS image compression. One straightforward method is to allocate an equal amount of rate to each segment based on the average of the total number of compressed bytes. The obvious drawback of this method is that different segment will be reconstructed to different quality so the overall quality of the reconstructed image will not be optimized. For the shortage of the original rate control method as to improve the overall quality of the reconstructed image an improved rate control algorithm is proposed for CCSDS image encoding. The key component of the proposed rate control method is the appropriate rate allocation. Experiments on the test images show that the PSNR can be increased at about 0.3dB on average compared to the original algorithm. Therefore experimental results confirm the effectiveness of the proposed algorithm in terms of objective evaluation and the rate-distortion performance of the reconstructed image is improved. 2011 IEEE.
	A combat effectiveness evaluation model based on interval number and grey decision making (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China Li H.; Guo L. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 During the combat effectiveness evaluation the evaluation values exist the precise number interval number and the language fuzzy number at the same time. For this question this paper introduces the interval number and grey decision making principle and bring forward a combat effectiveness evaluation model based on the interval number and grey decision making. Combined with the case to analyze this paper verifies the reasonableness of the model. The results show that this model can truly reflect the comprehensive evaluation value of the weapon equipment combat effectiveness. 2011 IEEE.
