six sigma methodology is one of the most famous effective problem solving approaches that helps organizations to achieve their goals. despite the variety of its positive advantage, most companies have failed to implement six sigma successfully. the reason for this includes lack of the organizations attention to success or failure factors when implement six sigma projects. hence, while performin...

six-sigma has some measures which measure performance characteristics related to a process. in most of the traditional methods, exact estimation is used to assess these measures and to utilize them in practice. in this paper, to estimate some of these measures, including defects per million opportunities (dpmo), defects per opportunity (dpo), defects per unit (dpu) and yield, a new algorithm ba...

In this paper, we introduce the notions of expansion of ideals in $MV$-algebras, $ (tau,sigma)- $primary, $ (tau,sigma)$-obstinate  and $ (tau,sigma)$-Boolean  in $ MV- $algebras. We investigate the relations of them. For example, we show that every $ (tau,sigma)$-obstinate ideal of an $ MV-$ algebra is $ (tau,sigma)$-primary  and $ (tau,sigma)$-Boolean. In particular, we define an expansion $ ...

-Six Sigma is a systematic methodology for continuous process quality improvement and for achieving operational excellence. Six Sigma methodology is designed to provide for the application of statistical tools in the context of a process improvement structure summarized by the acronym DMAIC– Define, Measure, Analyze, Improve, and Control. The DMAIC model provides a framework to identify and eli...

abstract background: today, the rate of surgeries is increasing, but surgeries are canceled due to various reasons. unexpected cancellation of surgeries not only results in disorder in the operating room schedule, but also causes stress for patients and their family and increases costs. we determined the number and causes of surgery cancellations and areas for improvement. materials and methods...

Six Sigma is a customer focused continuous improvement strategy and discipline that minimizes defects. It is a philosophy to promote excellence in all business processes with aggressive target goals. Six Sigma is a five phase methodology for continuous improvement which uses a metric based on standard deviation. It is also a statistic which describes the amount of variation in a process. Six Si...

In this paper, we give an overview about the current research in Big Data and Digital Curation with a focus on Lean Six Sigma and discuss how this methodology can help the Digital Curation lifecycle. For instance, the application of the Lean Six Sigma methodology is presented and discussed with a special focus on the selection, preservation, maintenance, collection and archiving of digital info...

Six Sigma provides an effective mechanism to focus on customer requirements, through improvement of process quality. In the Global Engineering Development Center of Tata Consultancy Services (TCS – GEDC) at Chennai, India, Six Sigma projects are being carried out with the objective of improving on time delivery, product quality and in-process quality. This paper describes the application of the...
