Abstract: Aimed at the characteristics of the hierarchical input output manufacture system analysis, a serials of input output models and products cost and efficiency analysis models are established, these models lay a foundation for the research of the hierarchical manufacture system’s input output optimization. In order to optimize the production configuration, how to transfer the non-structured factors into half-structured mode described by context knowledge is researched and is blended into the building and solving process of input output optimized model. At last the personalization processing of a practical application and the process of decision-making optimizing analysis in depth in respect of the maximal marginal contribution, maximal benefit of resource utility and unit consumtion sensibility analysis are introduced, it is very helpful to the enterprise’s management decision-making and consequently expands the research and application area of knowledge management on some degree.

Key words: Context knowledge, Decision analysis, Hierarchical manufacture system, Input and output optimizing, Knowledge management
