The mean,variance and the risk level under the above-mentioned two circumstances have also been compared with a case study.Also the sensitivity analysis of cost risk has been probed into. The result indicates that the model which takes into ac-count correlation is more objective, and the model which ignores the circumstance of correlation normally underes-timates the risk level of project cost.展开更多

With the rapid development of the domestic construction industry, the traditional engineering management model can not meet the needs of a large number of construction project information exchanges. Only realizing informationization of construction engineering management, can reduce the cost of construction projects, improve the efficiency of project management and construction progress. This paper analyzes the current situation of construction management informatization, and puts forward some suggestions to strengthen the construction management information construction.展开更多

This paper aims to establish a prototype of workflow management system for construction design project through the application of workflow technology. The composition and function of prototype is presented to satisfy the needs of information share and process integration. By integrating all subsystems and modules of the prototype, the whole system can deal with design information-flow modeling, emulating and optimizing, task planning and distributing, automatic tracking and monitoring, as well as network service, etc. In this way, the collaborative design environment of building design proiect is brought into being.展开更多
