GM model application in mine construction objectives integrated management

Quality,cost and schedule are the three objectives of project management,earned value management and lack of traditional quality management objectives,combined with earned value management added mass coefficient to achieve integrated management project management goals.For the shortcomings of traditional Earned Value Management has predicted the trend can only be based on existing data,the use of GM model can predict the data sequence advantage of mine construction project data to establish GM (1,1) model.From the prediction results,the model predictions with high accuracy near the point,the "total cost" of the prediction error (about 1%) is less than the "monthly cost" error (about 3%) features.So GM (1,1) model with a combination of earned value management is fully capable of building on the construction of mine play a guiding role.
