Monitoring Processes with Highly Censored Data
The need for process monitoring in industry is ubiquitous. By monitoring process output, problems may be rapidly detected and corrected. However, in many industrial and medical applications observations are censored either due to inherent limitations or cost/time considerations. For example, when testing breaking strengths or failure times often a limited stress test is performed and only a sma...
متن کاملEstimation for Weibull Distribution with Type II Highly Censored Data
Due to cost and time consideration, it is difficult to observe all of the product’s lifetime within a reasonable time period. Hence, censored lifetime data is usually collected in real applications. Even when accelerated life tests (ALT) are used, censoring is usually inevitable. Especially for highly reliable products nowadays, the censoring proportions are more likely greater than 0.5. Such d...
متن کاملMonitoring the Weibull Shape Parameter with Type II Censored Data
In this article, we introduce a method for monitoring the Weibull shape parameter β with type II (failure) censored data. The control limits depend on the sample size, the number of censored observations, the target average run length, and the stable value of β. The method assumes that the scale parameter α is constant during each sampling period, which is true under rational subgrouping. The p...
متن کاملFailure Process Modeling with Censored Data in Accelerated Life Tests
Manufacturers need to evaluate the reliability of their products in order to increase the customer satisfaction. Proper analysis of reliability also requires an effective study of the failure process of a product, especially its failure time. So, the Failure Process Modeling (FPM) plays a key role in the reliability analysis of the system that has been less focused on. This paper introduces a f...
متن کاملMonitoring the censored lognormal reliability data in a three-stage process using AFT model
Improving the product reliability is the main concern in both manufacturing and service processes which is obtained by monitoring the reliability-related quality characteristics. Nowadays, products or services are the result of processes with dependent stages referred to as multistage processes. In these processes, the quality characteristic in each stage is affected by the quality characterist...
