Group Decision Argumentation System For Complex Decision-making Tasks

Professor Qian Xuesen proposed the Hall for Workshop of Metasynthetic Engineering (HWME), which is a new methodology to solve complex Problems related to the Open Complex Giant System(OCGS).The HWME is a giant intelligent decision-making and problem-solving supporting system, which is People oriented and man machine integrated. The main idea of HWME is combining expert groups, all sorts of data and information, and the intelligence of computer together. Several key techniques should be studied, such as the architecture of HWME, the method of synthesizing the divergent thinking of experts and organizing discussion information effectively and etc.After analyzing correlative theories of HWME, proposed and designed a hierarchy dirved and complex decision-making task oriented workshop system for group decision-making, which is fit for requirement of software implement, and can do many works, such as disassembling man and machine integrated decision-making task, matching decision-making group, solving concurrent problems and synthesizing result. The paper expatiated functional models of the system structure, includes group structuring and management, decision-making task structuring and solving, conference management, workshop system supporting, workshop procedure controlling, knowledge searching and visioning and so on.Introduced task disassembling structure to disassemble complex decision-making, doing so can reduce the complexity of decision-making task, and improve the efficiency of group decision-making workshop. The paper proposed the multimodal matching arithmetic that based on task character and group member character to solve disassembled tasks, improved the speed and precision of decision-making, and validated validity of the arithmetic by an example. Analyzed the characters of workshop process and experts workshop information of group decision-making workshop system, summarized and designed the group decision-making process that integrated qualitative analysis capability of people and quantificational data disposal capability of compute. Then summarized and proposed the synthesis selective preference method of alternative, provided indispensable method and theory for group decision-making workshop system.Based on above research, implemented function of group decision-making workshop system based on Weber circumstance partly. The paper expatiated technique, strategy and operating circumstance of system development, as well as the developing steps of decision-making task solving and workshop procedure model.
