The Research On Quality-cost Excellence Management System Of Expressway Construction Project

Quality and cost are the two major components of project management "fourth control",also are the two protection element of expressway construction project investment profit. Atpresent, regardless of the theoretical research and practical operation, project management,quality and cost management both independent off, resulting in the quality and cost of theproject management imbalances, it is difficult to achieve the quality and costs at the sametime to meet the standard of investors. Excellence performance management model to theexpressway construction project quality and cost management provides an opportunity.Based on the current situation of the quality and cost management, the status quo establish aexpressway construction project quality-cost excellent management system, to enhance themanagement level.This article first details from the four aspects of the basic theory of the expresswayconstruction project quality-cost management excellence system. The understanding of thequality management and cost management, through the analysis of the quality and cost ofrelationship and summarize the quality and cost of management deficiencies: the lack ofcoordination, lack of comprehensiveness, the lack of coordination, recognizing the necessityand inevitability of the combination of quality and cost management; The basis of theexcellent performance management model theoretical knowledge, details the development ofexcellence performance management model, framework, core values and characteristics, andenhance the understanding of the meaning and essence of the excellence performance model;Relying on the basic theory of the basic theory of quality and cost management andperformance management excellence, and to define the expressway construction projectquality-cost management excellence；Analyzing the necessity of quality-cost excellentmanagement system. Second, build quality-excellent cost management system. The quality-cost excellence management defined based on lean construction, PDCA cycle continuousimprovement and performance evaluation of the three management philosophy as the guidingideology of the expressway construction project quality-cost excellence management systemconceptual model; According to constitute different elements of quality-cost excellencemanagement targeting,quality-cost excellent management process management and quality- cost excellence management subsystem elaborate; A brief description of quality-costexcellence management process management and implementation of the measures. Fourth, inorder to verify the feasibility of this system, built from the three levels of the target location,process management, performance management feasibility evaluation index system, establishentropy weight-fuzzy matter element extension model. Finally, analysis of theimplementation of expressway construction project quality-cost excellence managementsystem on Huang Qi Expressway, and data obtained through field investigations and studies,expert scoring, using entropy weight-fuzzy matter element extension model of Huang Qi onthe expressway construction project quality-cost excellence management system feasibilityevaluation.In this paper, advanced management mode-Excellence performance managementmodel, proposed expressway construction project quality-cost excellence managementsystem. It is an innovation for quality and cost management system, to enrich and improve theproject management system, improve the quality and cost of the expressway constructionproject management performance, promote excellent performance management model in theexpressway construction project management.
