The development process of the software system is influenced by multi factors, thus the risk control of software projects is of vital importance. Targeting at the features including multi-factor, multilayer, fuzziness and uncertainty during the process of risk assessment of software projects, this paper analyzed the risk measurement of software projects and proposed a multilevel risk measurement algorithm of software projects based on grey variable weight clustering model. This algorithm firstly analyzed the influencing factors of the risk control of software projects, establishing a multilevel risk measurement system for software projects; next, establishing the whitenization weight functions of different measurement indexes and different measurement grades of software projects risks respectively on the basis of the grey system theory, and under the condition of considering the degree of importance of the indexes of different levels, the corresponding risk measurement algorithm of software projects based on grey variable weight clustering model was established; then the paper presented the detailed execution steps of this algorithm and discussed the detailed process to achieve the algorithm. Finally, the algorithm was verified through the case study.
