英文摘要：

Project cost modeling and forecasting have very important research significance to the project management. In order to improve the accuracy of project cost forecasting, in view of the limitation of current project cost forecasting models, a novel method for project cost modeling and forecasting is proposed based on MCS-SVM. First of all, the status of current project cost forecasting modeling is analyzed, and main problems are pointed out. Secondly, support vector machine （SVM） is introduced to establish the model of project cost forecasting, Cuckoo search algorithm is used to estimate the support vector machine parameters. At last, a specific project cost data are selected to analyze the model performance. The test results show that the proposed model can get reliable prediction of project cost, it can provide valuable reference information for project management and decision-making.
