Estimating PLC logic program reliability
In earlier research we developed a theory for predicting the reliability of conventional sequential programs based on an estimate of residual faults. This paper describes how the theory was applied to a realistic industrial example containing a known number of faults. The industrial example was implemented in a PLC application language where the program is represented by a network of logic gate...
متن کاملEstimating Ordinal Reliability Using SAS
In evaluation instruments and tests individual items are often collected using an ordinal measurement or likert type scale. Typically measures such as Cronbach’s alpha are estimated using the standard Pearson correlation. Gadderman, Guhn and Zumbo (2012) illustrate how using the standard Pearson correlations may yield biased estimates of reliability when the data are ordinal and present methodo...
متن کاملEstimating Reliability for Each Study
The current paper describes and illustrates three things: (a) sampling variance and confidence intervals for Cronbach’s Alpha, (b) the relative precision of reliability estimates from local studies and meta-analyses, and (c) how to blend the local and metaanalytic information to create an optimal local reliability estimate according to Bayesian principles. The paper is not about artifact correc...
متن کاملEstimating Reliability of Conditional Promises
Using conditional promises, the reliability of promises can be measured without considering the reliability of the whole agent, by defining notions of when conditions operate and when promises are expected to be fulfilled. This inspires an analytical method based upon “incomplete conditions” that attributes failures to incomplete knowledge rather than operational faults. This analysis allows ag...
متن کاملOn estimating a stress-strength type reliability
This article deals with estimating an extension of the well-known stressstrength reliability in nonparametric setup. By means of Monte Carlo simulations, the proposed estimator is compared with its parametric analogs in the case of exponential distribution. The results show that the estimator could be highly efficient in many situations considered.
