Analysis of uncertainties in groundwater resource evaluation;

Besides, professional firms will also inevitably face uncertainties, the outcomes of which are unpredictable.

Focused on the uncertainties existing in investment estimation,Monte Carlo risk analysis method is applied to describe their effects on investment estimation.

The method first analyzed the variations of the constraints by considering the uncertain factors and then quantified the robustness of the constraints using maximum variation analysis.

Analysis of the influence of uncertain factors on certain value in item evaluation;

Furthermore,economic nonequilibrium was led to a great extent of uncertainty.

The uncertainty factors should be considered in economy assessment for electric power grid.

Impacts of uncertain factors on total time of construction for Beijing-Shanghai high speed railway;

The uncertain factor control in large span bridge engineering construction process

To solve this problem,the factors affecting the task assignment are analyzed,the interval numbers are used to express these uncertain factors,and a model of uncertain multi-attribute decision-making for the task assignment is built to assign the task more effectively in order to attain the objectives of minimum operating costs and top-quality.
