| 英文摘要 | The decision-making on problems related to Open Complex Giant Systems (OCGS) is among the most concerned problems in IT, Management Science, System Engineering and AI, etc. Generally, such complex systems are not only involved with several domains, but also have complex interaction with human, for example ecological, social and economic systems etc. Hall for Workshop of Metasynthetic Engineering (HWME), intelligent decision-making support systems in information era, offers professional platform based on internet for decision on such problems. As a system of knowledge producing and servicing for Learning Organization, HWME cry for professional analytic and decision-making knowledge reusing and reengineering. Based on Hypothesis of "Three World" and its interaction, this paper proposed expertise problem solving method based on cognition and Structural Concept System (SCS) for problem solving related to OCGS. Additionally, a formal knowledge representation based on ontology and knowledge reusing and reengineering based on it are put forward based on analysis on online organizational discussion in HWME. At last, knowledge management in HWME is explored. Firstly, present research related to Complexity science and difficulties of problem solving related to Open Complex Giant Systems (OCGS) are analyzed. Based on the analysis, motivation and theory for Metasynthesis are studied and the hypothesis of "Three World" and its interaction is given. Then the cognitive feature of experts in problems solving related to OCGS is studied and the framework of solving such kind of problems is forwarded based on Metasynthesis. To express the problems solving and SCS related to OCGS explicitly, we define Dynamic Concept Space (DCS) and discuss the achievement of DCS driven by problem-solving, the analysis of the relations between elements in the concept set and the process of building the network of SCS. The process that the experts make decision on the network of SCS and acquire the scheme of problem solving finally is studied thoroughly. Secondly, we analyses the online organizational discussion in HWME in-depth, in which experts as a learning organization discuss in some organized manner exchange their ideas and thoughts without mental barrier, influence each other and revise own ideas to come to an agreement on solving complicated problems with the aid of internet and IT. In the discussion process, the knowledge structure of the organization is shared, emerging and evolving with the knowledge systems in computers and experts' knowledge structure, which is emerging in his debate, his focus and the web resources he visited, can be reused, exchanged, influenced and revised in the organization. For the sake of interaction, share, reuse, evolvement and acquisition of the organizational knowledge system, the organization and integration of the multiple knowledge resources is studied and the concept tha |
