The classical method of process capability analysis necessarily assumes that collected data are independent; nonetheless, some processes such as biological and chemical processes are autocorrelated and violate the independency assumption. Many processes exhibit a certain degree of correlation and can be treated by autoregressive models among which the autoregressive model of order one (AR (1)) ...

Software process improvement and assessment guided by a maturity level or a process capability profile based on a capability/maturity model is now well established in practice as a successful means for improving software intensive organizations. Therefore, a wide range of software process capability/maturity models have been developed evolved and adapted over the past years. In this paper, we p...

Software process assessments have been used to verify the conformance with quality reference models or standards, usually in a context of software process improvement programs. Most of these assessments are concerned with just one specific model or standard. However, organizations could be interested in more than one model, being necessary to offer an integrated assessment that allows evaluate ...

The concept of process capability was proposed in early 1970 with the introduction of ‘capability ratio’ by Juran, a world known quality expert. Thereafter almost 40 years have been passed and many indices such as Cp, Cpk and Cpm were developed for measuring process performance. However, many researchers, for example, Kotz and Johnson [1-2] raised concerns about the application of the diversifi...

in the explosive growth of business to business (b2b) electronic trades, electronic markets have received a great deal of attention recently. the obtained profit of trading in e-b2b market encourage market participants to remain in the market. market participants consist of: sellers, buyers, and market owner. in this paper the expected profit function for each market participant has been define...

Process capability indices (PCIs) can be used as an effective tool for measuring product quality and process performance. In classic quality control there are some limitations which prevent a deep and flexible analysis because of the crisp definition of PCA‟s parameters. Fuzzy set theory can be used to add more flexibility to process capability analyses. In this study, the fuzzy X ba and MRx ba...
