Confidence bounds can also be estimatedĬalculation allows to define optimal replacement policy (time) under Kijima’s imperfect repair model with the underlying The Maximum likelihood and an efficient advanced Monte Carlo method are used. Time to repair can be also introduced into the calculation. Having event times of several components, the calculation allows to estimate parameters of the underlying lifetime distributionĪnd the restoration factor of imperfect repair. Using Kijima model with the following underlying lifetime distributions: Weibull, Normal and Log-Normal. Time to repair can be represented as a deterministic or random process with exponential distribution function.Īn efficient advanced Monte Carlo method is used.
Imperfect repair is described by Kijima models (I and II) with the following underlying lifetime distributions: Weibull, Normal and Log-Normal. This calculation allows analyzing Number of recurrent events,įrequency of events and probability that a component is down. The confidence bounds can also be calculated using the Fisher Matrix or the Likelihood Ratio method. For this purpose the following models can be selected by user: Benard, Hazen and Mean. To the corresponding probability values first. If the Rank Regression method is selected, the observed event times are converted Maximum Likelihood and Rank Regression method. This calculation allows to analyze and predict probability of events selectingĪn underlying distribution function: Exponential, Weibull, Normal or Log-Normal. The confidence bounds are also calculated. The following rank-regression models can be selected by user: Benard, Hazen, Mean and Kaplan-Meier. The observed event times are converted to the corresponding probability values. This calculation allows the user to analyze probability of events without any assumptionĪbout an underlying parametric distribution function.
We suppose that this calculation will be useful for researchers and engineers lookingįor good approximation of data with simple formula. Given accuracy, and correlation coefficient of data fitting. Three main parameters: number of coefficients of Pade function The accuracy of approximation can be managed by user changing values of Obtaining approximation of data using generalized Pade (rational) functions. Two calculations "Spherical shell" and "Shock absorber" are currently free.

Even though this is an inconvenience to you, the good news is that this additional income will allow us to develop the web site further.Īny improvement suggestions from you are very welcome.Īll calculations are free to try with restrictions on input parameters. Please view our subscription information. We have decided to charge our users a small amount of money to keep the web site running. Despite that thousands of calculations were performedĮach month, we obtained very little money, which was barely enough to pay for our operational expenses. We would like to thank those who had donated in the past to support our web site.
