Fuzzy Mathematical Model for Comprehensive Evaluation on Schemes of Coal Mine Design

引用

Systems science and Systems engineering 2000年第4期10卷 401-405页

作者： WANG Zhi\|jiang 1,\ GUO Dong\|qiang 2 1.Department of Management information science, huaqiao university quanzhou, Fujian 362011, China 2.Department of Business Admistration, huaqiao university quanzhou, Fujian 362011, China

The comprehensive evaluation of the schemes of coal mine design often involves some factors that are difficult to be expressed in quantity and these factors are often described ***, it is difficult for us to adopt uniformly concrete evaluation value to appraise each design plan. So the subjective view point of the design personnel plays an important role in choosing final plan. Sometime it will lead one sided decision, which will make the chosen scheme not optimized. Thus the quantitative model for evaluating design is set up by means of Fuzzy Mathematics and a concrete calculating example is given in this paper.\;The Fuzzy mathematical model proposed in this paper is good in adaptability and convenience. Both comments and degrees of importance in correspondence with the evaluated factors of each plan can be given qualitatively according to the people′s idiomatic expression by the model. After simple calculation, the quantitative result or comprehensive evaluation value that evaluates each design plan can be obtained,which provides a scientific basis for design personnel to choose the optimum scheme.

2007 IEEE International Workshop on Anti-counterfeiting,Security,Identification

作者： Ling chaodong (1) Chen fang (1) and Su wuxun (1) (1) college of information science & engineering of huaqiao university quanzhou Fujian China

The results of Chen-Mobius transform of some often-used waveforms were applied in the digital communication systems. In addition to modern digital communication systems, the new coherent modulation- demodulation systems by two classes of the oblique-orthogonal function set were applied to the communication systems. Then the new Chen-Mobius multi-carriers digital communication system was simulated by the MATALAB and the systems’ figures of its error rate to different ratio of S/N and by different function set were given and analyzed. Compared with the traditional system the results showed that the new system has excellent performances to resist the strong noise and interference and the reasons of which were discussed in some detail.
