Through analysis of the preseant situation of housing finance in our country and the devepment situation of mbs inside and outside our country , we raised the important theories and realistic meaning of mbs in our country and the purpose and significance of this thesis . we also raised the method of system studying the mbs in our country 本文首先通过对我国住房金融发展现状及国内外住房抵押贷款证券化发展状况的分析,提出我国实施住房抵押贷款证券化的重要理论与现实意义,进而说明本文研究的目的和意义。提出系统研究我国住房抵押贷款证券化的方法。
The system study of decision making science in our country begin hi the end of 1970s or beginning of 1980s , launching with reference and introduction of external decision making science theory , to this day , none but twenty years . our research lever is lower versus external research of decision making science , only getting to digest and absorb western decision making theory level 我国对于决策科学的系统研究起步较晚,七十年代末八十年代初,开始借鉴和引进国外的决策科学理论,到今天,对决策科学的研究只有二十几年的时间,还停留在消化和改进西方的决策理论的水平上。
In the process of the system study , the knowledge in the domain of ship collision avoidance is analyzed and the collision mechanism , process and the tactic are studied firstly . and then , using the fuzzy mathematics theory , the fuzzy mathematical model of judging collision risk is built , which take into account of the factors such as ship maneuverability , visibility and so on . in addition , based on the expert system theory , a design method of ship intelligent collision avoidance expert system is put forward , and the frame of ship intelligent collision avoidance expert system is built 在系统的研究过程中,首先对船舶避碰领域知识进行分析,并研究了船舶碰撞的原理、过程及对策;然后运用模糊数学理论,建立了一种评判碰撞危险度的模糊数学模型,该模型考虑了船舶的操纵性能、能见度等多种因素;接着根据专家系统理论,提出了一种船舶智能避碰专家系统的设计思路,并构建了一种船舶智能避碰专家系统的框架;最后以visualbasic6 . 0作为软件开发平台,设计了一种具有良好的可视化人机交互界面的船舶智能避碰专家系统软件。
