Calculation Model of Satisfaction Degree Based on Intuitionistic Fuzzy
基于直觉模糊的满意度计算模型

Abstract: Satisfaction degree theory is widely used in optimization, system control, management, decision-making, re- source allocation, task Scheduling, and other fields. But most of them based on background of the problem define and calculate satisfaction, which lack a universally applicable formalized satisfaction calculation model. Based on intuition fuzzy set theory, a universal multilevel intuitionistic fuzzy satisfaction degree calculation model was established. It effec- lively induces intuitionistic fuzzy satisfaction degree by using intuitionistic fuzzy filter operator. Combining qualitative and quantitative methods to calculate satisfaction degree, it makes the results more informative, scientific, reasonable and has a high automated degree. This paper analyzed the model's calculation complexity, and combining with a practical ex- ample computed the intuitionistic fuzzy satisfaction degree of shangluo tourism, and the result shows that the model is effective and practical.
基于直觉模糊的满意度计算模型

Abstract: 满意度理论广泛应用于优化、控制、管理、决策、资源分配、任务调度等领域,但大多是针对具体问题背景定义和计算满意度,缺乏一种普通适用的形式化满意度计算模型。基于直觉模糊集理论建立了一个普适的多级直觉模糊满意度计算模型;利用直觉模糊集算子有效地诱导出直觉模糊满意度,将定性与定量的方法结合起来进行满意度计算,使计算结果信息量更大、更加科学合理且自动化程度高。分析了该模型的计算复杂度,并结合实例计算了商洛旅游的直觉模糊满意度,结果显示该模型高效实用。

STUDY ON RADIO-TRACKING FINLESS PORPOISE NEOPHOCAENA PHOCAENOIDES,AT THE YANGTZE RIVER
长江江豚的无线电跟踪研究

Zhang Xianfeng,<br>张先锋
生态学报 , 1996,
Abstract: Radio-tracking techology was employed on finless porpoises, Neophocaena phocaenoides in an separated oxbow segment of the Yangtze River. Methods of non-injured mounting of radio tag on non-dorsal fin species and the tag falling off automatically in fresh water environment were developed. The tracking was successful.

Population viability analysis for the Yangtze finless porpoise
长江江豚种群生存力分析

ZHANG Xian Feng,<br>张先锋
生态学报 , 1999,
Abstract: 长江江豚是一个独立的种群,由于人类活动的影响,其数量呈下降的趋势,运用漩涡模型(VORTEX7.3)分析了长江江豚的种群生存力,预测了未来100a长江江豚的种群动态,比较了在假设环境条件下以及采取和不采取保护措施长江江豚种群的濒危程度,并模拟了江豚饲养群体的动态,主要结果显示,长江江豚在未来100a内灭绝的概率为0.01平均灭绝时间为100a,如长江环境状况进一步恶化,长江江豚的灭绝概率针大幅度提
Effects of temperature and osmotic potential on seed germination of Cleistogenes songorica and Plantago lessingii
温度和水分对无芒隐子草和条叶车前种子萌发的影响

YU Xiao-Jun,<br>小军
生态学报 , 2004,
Abstract: Cleistogenes songorica and Plantago lessingii are important native plant species in the north-west desert grassland of China, and play a significant role in pasture production and vegetation restoration. Research on factors affecting germination of these species has not been reported previously. A series of laboratory tests were therefore conducted to study germination response of the two species to temperature and osmotic potential. The temperature regime for both species included 5 constant temperatures(1...
Analysis and countermeasure of the hole in an intrusion detection modeling from immunology
基于免疫的入侵检测模型中空洞的分析及对策

Abstract: Inspired by the structures and ideas of natural immune system, a new instruction detection modeling was proposed to improve the capability of detection system. There may be some nonself strings that were not detected by any detector in the modeling, so named as "holes", which would lead to performance decline and increase the ratio of leak. After analyzing the formation reason and characteristics of the holes, some methods were presented to eliminate holes. It is proved by simulation experiments that different kinds of detectors can repair hole effectively, thereby false negative rate decreases.
