Fuzzy Reliability Analysis of Compound System Based on Weibull Distribution
نویسنده
چکیده
Data in the real world can not be recorded or collected precisely due to human errors, machine errors, or some other unexpected situations. And reliability analysis is an important research topic in engineering. The data, however, can not be recorded precisely sometimes as described above. Then some researchers pay attention to the fuzzy reliability. In this paper, we are going to analyze the fuzzy reliability of compound system, which obeys the Weibull distribution. For the compound system composed of multiple components, , , , , 2 1 n C C C ... especially when , 1 = η we obtain the corresponding fuzzy reliability function. Besides, values of reliability of compound system with various n and m have been calculated. Finally, necessary reliability analysis is also provided in the paper.

متن کاملBayesian Estimation of Reliability of the Electronic Components Using Censored Data from Weibull Distribution: Different Prior Distributions
The Weibull distribution has been widely used in survival and engineering reliability analysis. In life testing experiments is fairly common practice to terminate the experiment before all the items have failed, that means the data are censored. Thus, the main objective of this paper is to estimate the reliability function of the Weibull distribution with uncensored and censored data by using B...
متن کاملReliability analysis of a robotic system using hybridized technique
In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...
متن کاملA fuzzy reliability model for series-parallel systems
Fuzzy set based methods have been proved to be effective in handling many types of uncertainties in different fields, including reliability engineering. This paper presents a new approach on fuzzy reliability, based on the use of beta type distribution as membership function. Considering experts' ideas and by asking operators linguistic variables, a rule base is designed to determine the level ...
