Research On Knowledge Management Of Railway Engineering Cost Control Based On Ontology

Railway Engineering Cost Control has been the focus of the railway construction enterprise engineering project management in the implementation stage. A lot of scholars and experts to make a lot of work on the problem。At the same time, most of the railway construction enterprises will take active measures to the effective control of construction cost. But due to the lack of scientific experience, successful cases of cost control can not get effective secondary use. Knowledge management technology in order to solve the knowledge sharing and reuse provides effective solutions. This paper introduces the concept of knowledge management of railway engineering cost control of construction process. The knowledge management research of railway project construction cost control made a preliminary explore and try. For the realization of the railway project construction cost control the reuse and sharing of knowledge, and the realization of the intelligent and information technology provides the research train of thought.This paper analyses the actuality of railway project construction cost control, process and disadvantages. In the construction cost based on the analysis of the factors influencing the proposed railway project construction cost control the definition of knowledge management. This paper expounds the method of control process and its research scope definition. Knowledge management is the premise of knowledge acquisition and knowledge representation. Through certain knowledge of methods for construction of railway engineering cost control, we use the method of ontology for knowledge representation. Through the construction of railway engineering cost control knowledge and attribute definition. Using the protege 4.3 software to complete an ontology construction of railway engineering cost control is established in this paper. After done using ontology knowledge representation and knowledge reasoning process. Completed by the Jena reasoning machine simple rule reasoning, bias level can be determined. At the same time using the technology of case-based reasoning to complete the railway engineering construction cost control measures reasoning. Construction cost control management provides the optimal measures suggested. At the same time, the paper introduces the construction of railway engineering cost control based on knowledge ontology knowledge management system implementation steps. This paper’s main research results and the insufficiency.The paper uses the ontology of knowledge management and case-based reasoning technology of existing railway project construction cost control method for the study of innovation. The concept of knowledge management for railway project construction cost control provides a new method In the field of intelligent and the development of information technology. At the same time it can improve the management level of enterprises through the new solution proposal. It has the certain theoretical value and practical guiding significance.
