Study On Evaluation Of Construction Enterprise's Core Competence Based On GRAP-BPANN

In the baptism of the financial crisis, many enterprises converted crisis into opportunities, made extraordinary performance, one of the most outstanding is large construction enterprise. Summarizes the success experience, the leaders of Chinese construction enterprises said: Enterprise's development is inseparable from the comprehensive enhancement of core competitiveness. The core competitiveness of enterprises plays a vital role in enterprise's survival and development. Construction enterprises must depend on enterprise's core competitive ability in market competition to obtain continuous development and competitive advantage. Construction enterprises are facing the good development opportunities; the competition is more intense at the same time. How to improve the enterprise core competitive ability and strengthen the market competitive advantage, become the main problem construction enterprise facing.The scientific and reasonable evaluation is the premise of raising the construction enterprises'core competence. Many scholars proposed different evaluation index system and model from different perspective. That has an enormous influence to the study of construction enterprises'core competence. Accompanied with the coming of knowledge economy, intellectual capital has become the main source of enterprises'core competence. The perspective of study core competence also trued from resources, corporate culture, and human capital to intellectual capital.At present, the construction enterprise core competitiveness of enterprise strategy, most research from the Angle of human resources and other single building enterprise core competitive theories, Based on the core competitiveness on the value chain theory as a foundation, the knowledge capital for tools, from Angle of building enterprise core competitive power evaluation. First, introduced the core competitiveness of the enterprise theory, the construction enterprise core competitive power in the research of construction enterprise and status, Secondly, the focus from the Angle of intellectual capital of enterprise core competence, and combining research building enterprise knowledge value chain model from the Angle of capital construction enterprise established core competitiveness evaluation index system, Then, based on the core competitiveness evaluation index and evaluation of the nonlinear relationship between the results applied GRAP - BPANN, the gray correlation analysis method, enhances the BP algorithm of multivariable complex system modeling ability, Finally, the application of collecting data of 30 to network architecture enterprise training, training for a good network construction enterprise core competitive power evaluation, evaluation results.
