| Abstract: | The competition in 21st century will be the competition among different manufacturing chains. Manufacturing chain makes decision not only the core enterprise of the manufacturing chain but also a group of enterprises. Any significant decision in manufacturing chain will affect each enterprise in manufacturing chain, thus every significant decision should meet the desire and requests of each enterprise that be affected. Any significant decision should concentrate in the opinion of each member in the representative assembly or committee and obtain the authorization of the congress. Any vital question also should be discussed, made the decision and coordinated the moves by the representative assembly or the committee. With society's development and the technical progress, the knowledge and the information content is growing suddenly, the questions needs making the decision are more and complex, the single enterprise only depended on its own resources and the strength is unable to grasp all essential information, and hard to face all questions. The representative assembly formed by representatives from each enterprise in manufacturing chain can gather together experts of different knowledge structure and different experience, which make up the deficiency of single enterprise in resources, strength and experience with the aid of many enterprises' resources and the strength. This is not just increase several brains, but to establish an information complex to ensure the scientific of decision, which formed by different knowledge structure, applies scientific theory method and means, can mutually enlighten and has abundant knowledge. So it comes down to the group decision. Group decision questions have two types, one is the collectivity decision which pursue the holistic benefit of the group, the other is that the members in the group pursue its' own benefit and value against others, that means the game theory of interest conflict existed among the members. Currently, most scholars research the questions in manufacturing chain from the point of game theory, the research on collectivity decision, which pursues the holistic benefit of manufacturing chain, is limited. The group decision support systems used in the later stage of 1990s includes electronic conference system and working flow system. |
