Then , in order to adapt the cesd model of the complex systems more effectively , this paper expands the cesd framework and provides a software frame of computer aided esd study 在對(duì)該逆向esd方法進(jìn)行擴(kuò)展的基礎(chǔ)上,對(duì)計(jì)算機(jī)輔助逆向esd建模技術(shù)進(jìn)行了研究。
Based on the usage and maintenance - support process , this thesis acquires knowledge with the esd and cesd ( converse event sequence diagram ) method . first , this thesis gives the concept of cesd 為此,在事件序列圖(正向esd )框架基礎(chǔ)上,提出逆向事件序列圖(逆向esd )的模擬方法,以與正向esd相結(jié)合,用以滿足決策知識(shí)獲取的要求。
Third , it is that carries out a detailed and systematic study of the basic principles of cesd . the paper particularly makes the following extensions to cesd , such as or gate , “ n / k ” gate , expandable gate , feedback gate and renewable unit and transfer gate ( 3 )根據(jù)實(shí)際應(yīng)用需要對(duì)逆向esd進(jìn)行了擴(kuò)展,提出了或門、反饋、可擴(kuò)展門、自恢復(fù)、可更換單元、 n中取k門和轉(zhuǎn)移門等圖形符號(hào),豐富完善了逆向esd的建模元素。
Finally , the operation of pulse power supply system is analyzed on the basis of the improved esd , cesd and computer - aided esd software . this sample shows the applicability of esd and cesd methodology in knowledge acquisition technology of aid decision - making for missile - launching 最后用esd和逆向esd及輔助軟件來(lái)對(duì)導(dǎo)彈穩(wěn)壓電源電路進(jìn)行了示例分析,展示了esd和逆向esd方法在導(dǎo)彈輔助發(fā)射決策知識(shí)獲取中的適用性。
Second , this thesis systematically describes the framework and its basic modeling elements of esd . to overcome the drawback in fault analyzing capability of the esd method , the paper invents the cesd method , and gives out their basic modeling elements which include event , gate , condition , constraint and rule ( 2 )介紹了esd的基本框架,針對(duì)esd在異常因果關(guān)系分析中的不足,提出了逆向esd方法,給出了逆向esd框架的基本元素,包括事件、邏輯門、條件、限制和關(guān)聯(lián)規(guī)則。
