DEVICE estimation of reliability indices TECHNICAL SYSTEM by combining two samples when nuisance parameters are

摘要

The invention relates to computer technology and can be used for statistical information on product reliability analysis and evaluation.; The purpose of creation of a utility model - to provide a device that allows to automate the statistical estimation of the technical system reliability indices based on the unification of the two samples in the presence of nuisance parameter.; The goal is achieved in that the device through the application control unit, two memory units, two pulse counters, four summation units, the five division blocks, two subtraction units, two units squaring, four multipliers, two summation blocks, one block comparison and communication between them allows you to implement a method of evaluation of the technical system reliability and performance by combining the two samples in the presence of nuisance parameter.; Method of estimation parameters of the technical system reliability by combining two samples in the presence of the nuisance parameter that is implemented in this device is mathematically described by the formula; when θ ₁ ≥θ _2, wherein and - the sample means for each sample,; ; ;; n and m - the number of elements of the first and second samples,; σ _1, σ ₂ - the mean square deviation of the first and second samples,; Equation (1) describes the principles of operation and is the basis for evaluation of a device of the technical system reliability indices by combining two samples in the presence of interfering parameter.; The advantage of the device is that it allows assessment of the technical system reliability parameters, by combining the two samples in the presence of interfering parameter when the actuation formula is inaccurate, and the error in the relationship between the parameters can not be neglected.
