| Along with the fast development of construction projects, the investment of construction is increasing rapidly, and the number of elevator companies becomes quite huge. According to the statistical results of China Elevator Association, in recent 3 years, the overall sales of elevators has passed over 180,000 and the annual growth rate is nearly 10%, moreover, the sales in 2009 has already reached 260,000.As the major construction project- elevator installation project of public facilities, the project management competences of elevator companies has been important indexes of measuring its general competitiveness.However, a series of problems appeared as the fierce industry competition happened which led to the reduced operation costs. According to the statistical results of China Elevator Association, the number of large elevator companies has been over 300, as a result, the practical problems of product quality, installation quality and maintenance quality has been brought up. In addition, to measure and prevent risks in elevator installation effectively by quantitative methods is the key research topic in order to satisfy customers and promote the society influence of the companies. Firstly, the paper did literature research on elevator installation project management, then identify all the risks in the stages of contract management, preparation before the delivery, installation, evaluation and transfer phase and classify them into 4 kinds, secondly, the paper constructs the risk measurement model in elevator projects by using QFD and ANP, thirdly, the paper applies the model in a practical case and gives several useful suggestions according to the results of the case, the results show that the application of risk measurement model can reduce the operating risks, raise the systematicity and scientificity of risk management and provide convincing proof of enhancing the competitive capacity of elevator companies. |
