Application Of Case-Based Reasoning In SIDSS On The Socket Launch Emergency And Safeguard System

With the "shenzhou" airship flight success, our country's astronautics enterprise entered a rapid development period. How to improve safety emergency support capabilities and real-time decision means, it has been difficult problems that must be solved in space launch field. Rely on modern science and technology, especially computer technology as the representative of the information processing technology to provide space to handle an emergency decision support, address space launch the initial phase of the flight emergency security issue and the realization of rocket launch an emergency command decisions more scientific and intelligent, automatic. Therefore, the establishment of satellite emergency support system is of great practical significance.In this paper, the establishment of intelligent decision support system based on the use of space MAPGIS building intelligent decision support systems. Expounded on geographic information systems and intelligent decision support system for the basic concepts, detailed analysis of the structure and the relationship between Based on geographic information systems and intelligent decision support system analysis of the advantages and disadvantages. a combination of the two space intelligent decision support system for decision support. Analysis of the spacecraft system of emergency protection features, basic principles and basic tasks, completion of the system's overall design and function module design. Through the system, data flow, and emergency command framework for the organization and the decision-making process, completion of the entire system operation modes of design. Then case-based reasoning into the space launch emergency systems, an analysis of the similarity of plans, detailed analysis of the function of distance, paper weights used to introduce the similarity calculation method was used to calculate disaster plans for the similarity. Decision-making through the establishment of contingency plans for the use of case-based reasoning to achieve a rapid emergency decisions, automatic generation. Finalization of the system and the overall structure of the CBR-based decision support system.This paper from decision support data-level research in space onto intelligent decision support system. decision-making through the establishment of contingency plans for the use of case-based reasoning to achieve a rapid emergency decisions, automatic generation. Put programs and cited cases of IDSS, IDSS decision to expand the scope of the data, decision-making data sources and more rich source of knowledge and technology can be applied to more IDSS. IDSS improve the processing semi-structured and unstructured decision-making problems.This system joined in some astronautics launch task, it prove can satisfy emergency decision-making's demand, it has achieved the system design goal, has the great practical value and the extend significance.
