In spite of these advantages , we should concentrate on how to extend the representation of modes , how to apply to unstructured grids , etc . and when combining pod and saa , it is necessary to know how to represent the shape and how to control the range of seeking and iteration number 但在研究的过程中,我们发现正交分解方法也存在如下问题:如何增强基模态的表达能力,如何将该方法应用于非结构网格的计算等。在利用模拟退火算法结合解算器进行翼型反设计时,则需要考虑如何表达几何外形形状,怎样控制搜索范围以及如何减小搜索次数等实际问题。
5 . in the background of the design and implementation of network management system for the local network of china mobile , we have analyzed and designed detailedly the key technique , approach and software architecture of a practical network management system based on starbus , which use mhnm architecture , the scheme of managed objects arrangement , saa , gpa and practical skills achieved when we developed china post and china broadcast and tv network management systems . in the end , we summarize the main achievement of this paper and state some further work in the future 5 .以中国移动通信网本地网网管系统设计为背景，以我们先后开发中国移动通信网本地网网管系统、广电有线电视传输网网管系统和邮政网网管系统的实践为基础，结合多级网络管理体系结构ml江nm 、管理信息的组织策略、提取管理信息的自适应算法saa和组预取算法gpa ，在基于corba的分布计算软件平台starbus上，详细分析了基于corba技术实现实用的异构网管系统集成管理的关键技术、途径和软件结构。
3 . as there are up to 106 managed objects on element level of tmn ( telecommunications management network ) in telecommunications network , and the scheme to collect management information affects the performance of network management , a new algorithm - saa ( self - adaptive algorithm ) used for retrieving multi objects information has been put forward in this thesis . saa can adjust the retrieving objects and interval of retrieval self - adaptively by using the schemes of self - adaptivity , fault tolerance , recognition status of object dynamically etc . , and thus can use fewer network resources without alteration of snmp ( simple network management protocol ) , iiop ( internet inter - operability protocol ) or cmip ( common management information protocol ) 针对传统的定时提取网络管理信息方法的不足，提出了一种提取多管理对象信息的新算法? ?自适应算法saa ( self - adaptivealgorithm ) ，该算法能在不改变管理协议，如iiop ( internetinter - operabilityprotocol ) 、 snmp或cmip ( commonmanagementinformationprotocol ，公共管理信息协议)的情况下，采用自适应策略、容错策略、动态识别被管对象状态策略、被管对象存储空间的动态刷新策略，根据本次访问被管国防科学技术大学研究生院学位论文对象所得出的网络通信量，自适应地调整下次应该访问的被管对象和读取被管刘?象数据的时间间隔，从而可以较少地消耗所用的网络带宽和cpu资源。
Then a new improving scheme of ga which we call it hgsaa ( hybrid gentic - simulatd annealing algorithm ) is put forward based on the existing condition , and the new algorithm works more efficiently than the old one because it has not only ga ' s global searching capability but also saa ' s local searching capability . the simulatio results show the new algorithm is more effective than ga . the minimum cost is reduced and the clustered network structures have been produced with the onus are evenly distributed or clustered around the obds and the clustered network structures are well ordered with a satisfactory degree of symmetry after the hgsaa has runed 100 generation 吏为重要的是，本文充分利用了混合遗传算法的思想，将遗传算法和模拟退火算法的优势相结合，使得遗传算法的全局寻优能力与模拟退火算法的局部寻优能力在该问题的求解过程中充分发挥了作用，由本文实现的混合遗传一模拟退火算法明显地改进了算法的效果，由此生成的网络方案的建设费用得到极大减少，同时拓扑结构的优化结果也比单纯的遗传算法的效果好得多。
