Value2, Value3, and Value4 Data Types Hard Data Data Type: 0 Value1&2 Fields: Data Value Soft Data (Uniform) Data Type: 1 Value1 Field: Lower Bound Value2 Field: Upper Bound Value3 & 4 Field: Dummy

Soft Data (Gaussian) Data Type: 2 Value1 Field: Mean Value2 Field: Standard Deviation Value3 & 4 Fields: Dummy Data Types Soft Data (Triangular) Data Type: 1 Value1 Field: Lower Bound Value2 Field: Upper Bound

Value3 Field: Mode Value4 Field: Dummy Soft Data (Trunc. Gaussian) Data Type: 4 Value1 Field: Mean Value2 Field: Standard Deviation Value3 Field: Lower Trunc.Value Value4 Field: Upper Trunc. value Data File Example Lower Bound: 24.5

Data Type: 1 (Uniform) Upper Bound: 51.45 Mean: 18.1 Data Type: 2 (Gaussian) Standard Dev: 38.01 Data File Example Use Data Type

To use soft data, check Use DataType Set Data Type, Value1 Field, and Value2 Field Hardened Data Histogram/Basic statistics Soft data is

hardened Uniform Mid-point Gaussian Mean value Std. formulas for others Hardened are used in values
