The concept of Value At Risk(VAR) in Earned Value Management(EVM)becomes mature. Thus,in this study,we improve the model of Schedule at Risk(SAR) by bootstrap,Delta Normal method and Earned Schedule(ES).Besides, the proposed method combines the concept, theory and model which is used to assess the loss of the VAR in practice.We will use the volatility of schedule ,SAR and EVM to predict the value at risk of the schedule and do the relevant differences comparative analysis, verification, discussion and improvement in the case: Longjing solar power plant.
