Research On Knowledge Representation And Reasoning Mechanism For Distributed Decision Making

Knowledge representation and Reasoning mechanism have been the focusing topics of Computer Artificial Intelligence and Intelligent Management.Distributed decision making is the most important, the most complex, the most active, and the most creative state in the process of the enterprise management. Research on knowledge representation and reasoning mechanism for distributed decision making is a challenge task. The thesis taked about Extension-Based knowledge representation thoroughly, which has significant theory and engineering value for solving the bottleneck of distributed intelligent decision support system.The thesis analyses the meaning,characteristic and process of distributed decision making, summarises the method of knowledge representation and reasoning mechanism, and combines the theory of the Extenics and transformation theory of matter-element, the thesis suggests Extension-Based knowledge representation and reasoning method. And finally through real example analysis, the validity of the theory is proved.The thesis's main conclusion and contribution are as follows:(1)Research on Knowledge Representation,Reaoning Mechanism and the Extenics etc..in great detail.Then,based on the analysis of decision making and distributed dicision making, Analysis the disadvantages and shortcomings of the existent knowledge representation methods and reasoning mechanism in the aspect of distributed decision-making knowledge representing and Reasoning.and design new knowledge representation method and reasoing mechanism based on Extenics.(2) Research on Decision-making and Distributed Decision making, analyses the meaning,characteristic and process of distributed decision making, the knowledge used in the process of the distributed decision making is thoroughly analysed.(3) According to the Extenics, research on the extension method of knowledge representaion, the formal definition of extension knowledge representation are proposed,including matter-element knowledge representation, affair-element knowledge representation and relation-element knowledge representation.(4)Based on transformation and extension of matter element,matter-model of the dicision-making problem and divergent-based extension reasoning are proposed,and then the extension representation method in the decision rule of distributed decision-making problem are analysed,the decision rule consists of undeterministic problem decision rule and risk problem decision rule.Finally extension estimation reasoing is talked about。(5)Carry on the real instance analysis, use the new knowledge representation method and reasoning mechanism talked about in this thesis to annlyze the historical data, the validity of the extension knowledge repsentation and inference mechanism is verified. The innovative point of this thesis is that it applies the Extenics to research the disitributed decision-making knowledge representation method and carry on corresponding extansion reasoning mechanism. Firstly matter element-based knowledge representation is proposed and then corresponding reasoning mechanism is designed, finally real instance analysis carried on to prove the validity of the extension knowledge representation method and extension reasoing, so as to as to reflect the actual meaning of the study.
