Abstract


Knowledge map has caught the attention of many social science researchers, since its concept was put forward by B.C.Brooks in1981. However, it has not been applied in practice widely for the limitation of information technology. Along with the development of information technology, lots of enterprises have possessed the conditions to apply knowledge map and knowledge is becoming the first development factor for enterprises. In some sense, the application Research on knowledge map oriented to a certain domain has again become the focus of academia, information technology trades and many enterprises.In accordance with knowledge requirement, this paper puts forward knowledge map in application of PLCC (Product Life Cycle Cost) control, which is a procedure of total process, total staff and all aspects. Fisrtly, under a systemic method, combining hierarchical control and unit-based responsibility control, the whole procedure of PLCC control is analyzed; and through process analysis, role analysis and subject ananlysis, the knowledge map requirement for manufacturer enterprises is discussed. Secondly, adopting ontologies, it provides a conceptual model of knowledge map, which is made up of four logic layers and five basic elements, as guidance to the construction of target knowledge map for PLCC control. Thirdly, it has developed the ontology special in PLCC control domain and completed the organization and description of PLCC knowledge, by comprehensive use of skeletal method and seven-step method. It has also extracted knowledge nodes into knowledge views, identified by their process attribute, contributors attribute and theme attribute; assisted by Protege4.1, knowledge maps in presentation layer are visualized. Lastly, taking product design stage for example, it analyzes the application use of PLCC control knowledge map. In summary, three maps constructed in the paper, saying process-type knowledge map, capability-type knowledge map, theme-type knowledge maps, have realized the intergrated management and application of PLCC knowledge, and satisfied knowledge requirement of different levels’staffs within the organization, helping achieve PLCC goal more effectively.
