FREE SDI UTILITIES
DISTRIBUTION EXPLORER
FEATURES
- Plot various probability distributions (Normal, Exponential, Lognormal, Uniform, Triangular, Weibull)
- Specify lower and/or upper specification limits and visualize their impacts on the distribution.
- Specify Target value and see it on the distribution.
- Automatically calculate the Probability of Non-Compliance (PNC) for areas below the lower specification limit, above the upper specification limit, and total area.
- Fit mean, standard deviation, skewness, and kurtosis to Johnson SB, Johnson SL, or Johnson SU distribution.
- Dynamically change the specification limits and their the impact on Probability of Non-Compliance (PNC).
- See effects of changing skewness and kurtosis on the shape on a probability distribution.
REQUIREMENTS
- Microsoft Windows 7, 8, or 10
RELIABILITY TEST DESIGN
FEATURES
- Design a reliability demonstration test using a cumulative binomial approach.
- Specify Test goal in terms of reliability, BX life, or MTBF.
- Define distribution (Weibull or Exponential)
- Select calculated results (Test Time, Test Units, Allowable Failures, or Confidence Level).
REQUIREMENTS
- Microsoft Windows 7, 8 or 10
PNC / TEST EFFECTIVENESS CALCULATOR
FEATURES
- Calculate true Probability of Non-Compliance (PNC) independent of a measurement system variability.
- Calculate the total probability of units that pass a test (both good and bad units).
- Calculate the total probability of units that fail a test (both good and bad units).
REQUIREMENTS
- Microsoft Windows 7, 8, or 10
- Microsoft Excel 2007, 2010, 2013, or 2016
