Research On Capacity Support System Of Team Knowledge Learning In Large-scale Construction Projects

The knowledge economy is the knowledge-based economy, and its development is on the basis of knowledge. Effective knowledge learning is the strategic response for organization to new situation and the inevitable requirement of the knowledge economy era. Along with the rapid development of national economy and technology, the scale of projects is getting bigger, and the system is also more and more complex, while the demand for knowledge is growing. But the loss of knowledge in project is serious, the utilization coefficient is low. These problems have not been effectively restrained, which make the development of large-scale projects affected and restricted seriously. Therefore, implementing knowledge learning in the large-scale construction projects, is the only way to meet the demand for knowledge, and to improve the utilization coefficient of knowledge.The existing researches on team learning are usually confined to certain aspect, and the systematic analysis is lacked. Through mechanism analysis and system designing, the effective means to solve the problem of project team knowledge learning were explored.(1) Through defining the concepts of team learning ability in large-scale construction projects, the conditions about knowledge learning ability were cleared. Combined with the three elements of knowledge learning process, the system of team knowledge learning capacity in large-scale construction projects, taking basic ability, process capability and the effect as main body, was constructed.(2) On the basis of capacity analysis, through literature analysis, the action mechanism of team knowledge learning ability in large-scale construction projects was discussed. Then the theoretical model of team learning capacity in large-scale construction projects was constructed, and the research hypotheses were put forward. Based on variable metric, the questionnaire were designed and distributed. SPSS18.0and Lisrel8.7were selected as the auxiliary tools for verification and validation. Through descriptive statistical analysis, the reliability, authenticity and accuracy of questionnaire were validated. Through exploratory and confirmatory factor analysis, the uniformity between the factors of knowledge learning and presupposition was tested. Through regression analysis of SEM, the data verification and validation of theoretical model and23hypotheses was passed. According to the results of analysis, by designing support system to strengthen the effect of project team learning were put forward.(3) In the Study of technique system, knowledge map was chose as a technique tool. The engineering change was determined as the core business process in project. Taking the database of construction technology in a large-scale construction project as an example, practicability and operational processes of project knowledge map was explained. For its limitations, the recommendations and measures for improvement were proposed. An application model of knowledge map to engineering change was constructed. The hardware facilities and technical support were provided for promoting of knowledge learning efficiency.(4) In the study of structure system, based on the characteristics analysis of organization structure and large-scale construction projects, strong-matrix organization was chose as the best form for large-scale construction project. Game theory was taken to explore the model of all-dimensional motivation. Prisoner's dilemma of team learning in the model of traditional motivating was broken. Take the project as an example, its organization form and incentive system were analyzed and illustrated for improvement. The promotion and popularization of team learning in projects were ensured from the aspects of organization structure.(5) In the study of culture system, the construction of knowledge learning culture in project team was discussed from three aspects: institution, spirit and behavior. Organization culture is the key factor for the efficiency of team learning. Features of organization culture supporting for knowledge learning were analyzed. Key factors for establishment of organizational culture were clear. Based on Construction steps, specific ways to realize organization culture construction were put forward. Finally, Analysis of an example was taken. The training of knowledge learning consciousness, the improving of learning initiative, and the reducing of knowledge loss were secured from the aspects of institution, spirit and behavior.
