When all of the one-sided specification indices each quality characteristic reach requirements process level, they can ensure that capability product meets level. This study constructs a fuzzy membership function based on upper confidence limit index, derives critical value, and then labels value axis visualized radar chart as well connects adjacent points to shape regular polygonal region. Nex...

Alternative definitions of Process Capability Indices (PCIs), based on different approaches, have been proposed in literature. Most of the research works related to Process Capability Indices assume no gauge measurement errors. However, in industrial applications, despite the use of highly advanced measuring instruments, account needs to be taken of gauge imprecision. The aim of this paper is f...

in many applications the quality of a process or product is best characterized and summarized by a functional relationship between a response variable and one or more explanatory variables. profile monitoring is used to understand and to check the stability of this relationship over time. therefore checking the capability of a profile seems essential. process capability indices have become very...

Ranking fuzzy numbers plays a very important role in the decision process, data analysis, and applications. The last few decades have seen a large number of methods investigated for ranking fuzzy numbers. The most commonly used approach for ranking fuzzy numbers is ranking indices based on the centroids of fuzzy numbers. However, there are some weaknesses associated with these indices. This pap...

the present article discusses and presents a new and comprehensive approachaimed at measuring the maturity and quality of software processes. this method has beendesigned on the basis of the software capability maturity model (sw-cmm) and themulti-level fuzzy inference model and is used as a measurement and analysis tool. among themost important characteristics of this method one can mention si...

— Using Sen’s capability approach, we propose to measure two components of wellbeing—standard of living and quality of life. Unlike the UNDP Human Development Index, the two indices do not mix measures of resource availability and of functioning and capability. The empirical results for 170 countries are based on two multidimensional analyses, the Totally Fuzzy Analysis and the Factorial Analys...

Traditionally, the process capability index is developed assuming that the process output data are independent and follow normal distribution. However, in most environmental cases, the process data have more than one quality characteristic and exhibit property of autocorrelation. We propose two novel multivariate process capability indices for autocorrelated data, NMACp and NMACpm for the-nomin...

This study develops a novel procedure for measuring the process capability indices of a complete product with several quality characteristics. The p-values of the estimators of Cpl , Cpu , and Cpp, so that the process works at least 100(1−α)% of the time, are provided. An evaluation checklist is also given to determine whether the process’s potentiality and performance meet consumers’ expectati...

In today’s competitive business environment, it is becoming more crucial than ever to assess precisely process losses due to non-compliance to customer specifications. To assess these losses, industry is widely using process capability indices for performance evaluation of their processes. Determination of the performance capability of a stable process using the standard process capability indi...
