• Reliability and Confidence Program - (PRELCON) - This program is for determining the Reliability and Confidence Requirements dictated by Economic Factor.

• Designing Life Test based on Economics Program - (SAMPROF) - This program is for designing life tests with sample size sufficient to assure a desired degree of profitability.

• Confidence Determination for Profit Factor Program - (CONFINT) -  This program is for determining a Confidence Interpolation Table for profit factor as predicted from reliability tests

• Statistical Entropy (Cumulative Hazards) Method Programs- (CARS5A) - Entropy Method of estimating Weibull parameters of field life. This has demonstrated superb value because of the intrinsic ability of the Entropy concept in measuring the built-up of failure rate per system These Entropy programs were based on such method. Each program of the Entropy Concept handles suspended items as well. The Co-ordinate Interval Program handles repeated failures on same system and the Grouped Mileage Entropy Method Program handles large grouped mileage data.
  

• Improving the New Increment Technique Weibull Program- (ACTLSQWB) - By including all the partial activity contributed by the suspended items in a life testing data set, this improves the accuracy of Weibull parameter determination by least squares statistical approach using the Median Ranks of actual failures as determined by the new increments obtained from including partial activities of suspended items in each interval between successive failures. This program displays  a semi-parametric 90% Confidence Plot as well.  This program is the most accurate of all the above methods.
  

• Iterative Reliability Program- (ITEREL) - The Logical basis of taking account of actual successive upward revision of reliability as employed in estimating reliabilities from life test data consisting of success runs. This program is mathematically derived and came  up with same conclusion when the Parabolic Exponent as K = 0 (Same results as with Extrapolation Reliability Program)
  

• Attribute Reliability Program (ATTREL) - For calculating the reliability which can be guaranteed with any specified confidence C when D defectives have been observed in N trials.

Special Applications of Weibull Distribution 

• Mixtures Program - (Decomposition of Population Mixtures) - This program deals with the problem of decomposing an S-Shape Weibull population and calculates the Weibull parameters and the goodness of fit for each sub-populations and the composite curve.

• Zero Minimum Life Weibull Program with Comparison - (ZMLCOMP) - This program computes the Weibull slope, Quantile Life, and Goodness of Fit on individual data set and permits comparison of data sets for significant differences. (This program does not handle suspensions.)

• Given Weibull Slope Program - To fit the best function with a given slope to a set of order statistics.

• Coordinate Weibull Program - (COWPRG) - For fitting Weibull cumulative functions to sets of coordinates and calculates the Weibull parameters for all the minimum life values in the interval between its lower and upper limits as well as goodness of fit for each assumed minimum life. 

• General Weibull Comparison Program - (GWCPRG) - For comparing two Weibull samples at any quantil level, and for any desired null ratio.

• Slope Comparison Program - To calculate the confidence of two Weibull slopes

• Weibull Repair Program - (WEIRP) - This program calculates the expected number of repairs on n machines in time x.

Other Interesting Distributions for Reliability Studies

• Cumulative Distribution Function - Ultimate Value Program - (CDF) - For fitting Ultimate Value Function to order statistics and  calculates the Ultimate Value parameters such as Slope, Minimum Value, and Ultimate Value as well as the goodness of fit with the assumed minimum value.  (This program handles suspended items as well.)

• Cumulative Distribution Function - N-tic Power Function Program - (CDF) - For fitting a three-parameter power function (Not Weibull function) to order statistics and calculates the minimum life value, N-tic slope, and Maximum life value as well as the goodness of fit with the assumed minimum value.  (This program handles suspended items as well.)

• Pearson Type III Statistics Program - (PEARS) - For fitting a Pearson Type III distribution to raw data and calculating the Pearson Type III parameters such as the mean, the standard deviation, and skewness.
