چکیده

The paper presents the application of several process control-related methods to the monitoring and control of data quality in financial databases. The quality control process itself can be seen as a classical control loop. Measurement of the data quality is conducted via application of quality tests, which exploit data redundancy defined by meta-information or extracted from data by statistical models. Appropriate processing and visualization of the test results enable human or automatic diagnosis of possible data quality problems. Selected model-based process monitoring methods are shown to be useful for detection, diagnosis, and, in some cases, also compensation of data quality problems. The test results are of interest not only for data quality control but also for business-relevant information extraction and monitoring. The presented methods are incorporated into our DQontrol product [1], and have been applied in the monitoring of a productive financial database at a customer site.

A DMAIC approach for process capability improvement an engine crankshaft manufacturing process

The define–measure–analyze–improve–control (DMAIC) approach is a five-strata approach, namely DMAIC. This approach is the scientific approach for reducing the deviations and improving the capability levels of the manufacturing processes. The present work elaborates on DMAIC approach applied in reducing the process variations of the stub-end-hole boring operation of the manufacture of cra...

Monitoring Lognormal Reliability Data in a Two-Stage Process Using Accelerated Failure Time Model

The reliability data is getting used to monitor and improve the quality of products or services. Nowadays, most of products or services are the results of processes with dependent stages referred to as multi-stage process. In these processes, the quality characteristics are affected by the quality characteristics in the previous stages, called as cascade property. In some cases, it is not possi...

A Self-starting Control Chart for Simultaneous Monitoring of Mean and Variance of Simple Linear Profiles

In many processes in real practice at the start-up stages the process parameters are not known a priori and there are no initial samples or data for executing Phase I monitoring and estimating the process parameters. In addition, the practitioners are interested in using one control chart instead of two or more for monitoring location and variability of processes. In this paper, we consider a s...

The effect of parameter estimation on Phase II control chart performance in monitoring financial GARCH processes with contaminated data

The application of control charts for monitoring financial processes has received a greater focus after recent global crisis. The Generelized AutoRegressive Conditional Heteroskedasticity (GARCH) time series model is widely applied for modelling financial processes. Therefore, traditional Shewhart control chart is developed to monitor GARCH processes. There are some difficulties in financial su...
