Process yield has been an essential criterion used for manufacturing industries in business management. Quality managers and engineers involved in factories require capability analyses to access process yields, particularly, for processes with a very low fraction of defectives. It is noted that the accuracy of process yield is important; as it is one of major considerations for supplier selecti...

Process capability indices Cp, Cpk, Cpm and Cpp fitting for nominal-the-best type quality characteristics, are effective tools to assess process capability since these indices can reflect a centering process capability and process yield adequately. The index Cpp introduced by Greenwith and Jahr-Schaffrath [Greenwith, M., Jahr-Schaffrath, B.L., 1995. A process incapability index. International J...

Process capability is an important concept for industrial managers to understand. The challenge in today’s competitive markets is to be on the leading edge of producing high quality products at minimum costs. This cannot be done without a systematic approach and this approach is contained within what has been called “statistical quality control” or “industrial statistics.” The segment of statis...

Process capability indices are widely regarded as a flexible means of evaluating the quality and performance of a process. Accreditation by the Quality System Requirement QS9000 requires an agent to conduct a global evaluation on the process capability over the entire product family from a plant. Generally, the process capability of the whole product family is an important reference for evaluat...

a manufacturing process cannot be released to production until it has been proven to be stable. also, we cannot begin to talk about process capability until we have demonstrated stability in our process. this means that the process variation is the result of random causes only and all assignable or special causes have been removed. in complicated manufacturing processes, such as drilling proces...

Abstract of Re-engineering of Industrial CMMI Through this research, I have established a general strategy to appraise an organization against a scale of five process maturity levels whilst maintaining a strong mechanics of CMMI. Reengineering of industrial CMMI proposes a novel method for Industrial Competence ranking of those organizations/companies which are targeting various CMM...

rangelands are important for plant productivity, livestock production, wildlife,conservation of soil and water resources, and etc. one of the main problem of rangeland isthat has not been used based on its potential that leads to more degradation of rangelands.the purpose of this study was to evaluate the range management capability of badrehregion in ilam province, iran, using anp (analytic ne...

Process capability indices PCIs aim to quantify the capability of a process of quality characteristic X tomeet some specifications that are related to ameasurable characteristic of its produced items. One such quality characteristic is life time of items. The specifications are determined through the lower specification limit L , the upper specification limit U , and the target value T . Maiti ...
