Research On Knowledge Acquiring Technology Of Aid Decision-Making For Missile-Launching

Missile-Launching process is dynamic and irreversible. It is important that the commander can determine whether launching the missile or not according to testing data and technical state. The systematic knowledge about Decision-Making for Missile-Launching is absence now. As we can discover the underlying abnormity in the training process. Acquiring causal knowledge of abnormity is essential to Missile-Launching reliably. There are lots of Knowledge Acquisition methods. But it is absence for usage and maintenance support process. So it is necessary to start the research on new knowledge acquisition technology of aid Decision-Making for Missile-Launching. 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. 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. For this purpose, the thesis has made its research in these aspects:First, as foundation on which acquires knowledge on the maintenance support of equipments, lots of theories and methods of KA (Knowledge Acquisition) and maintenance support of equipments have been widely studied. This thesis invents the method of KA which bases on researching of the maintenance support of equipments. And the paper explains theories and methods of it.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.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.Furthermore, the paper provides a software frame of computer aided ESD study. In addition to the composition and function of the software, the working process, data organization and the main techniques and methods of its realization were introduced in detail.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.
