Rapid technological advancement and implementation of automation computerization in today's manufacturing set up resulted many high quality processes, where defects are rarely observed. There processes two or more types may be generated from different equipment/process problems. The zeroinflated data containing commonly modeled by bivariate zero-inflated (BZI) Poisson distribution. Pal Gauri (2...

Process capability indices are designed to describe how the process of interest can achieve to meet specification limits under a condition of statistical control. One of the capability indices is denoted as Cpm proposed by Chan, Cheng and Spiring (1988), sometimes termed the Taguchi index. The primary goal of this paper attempts to construct a confidence interval for Cpm, which measures proces...

As is discussed by Walker, Abraham De Moivre first discovered the Normal distribution in 1733. This theoretical distribution has since been found to model many real life situations well, including distributions of heights and weights. It is very important in statistical theory, for example via the Central Limit Theorem (CLT). Though this theorem assists us in control chart methodology, it serve...

We know that Innovation plays a crucial role in sustainable development for small and medium enterprises (SMEs) cluster. This paper applies a multi-criteria methodology to SMEs cluster innovation capability appraisal, known as the analytic hierarchy process(AHP). This methodology is especially useful when there is partial information and/or qualitative variables are used. Firstly, this paper de...

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))...

Multivariate Process Capability Indices (MPCI) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. Process capability is an important and commonly used metric for assessing and improving the quality of a production process. When quality charac-teristics of a product are correlated then an attractive comes close to MPC...

Multi-tenant is the key feature for SaaS application, however, the traditional indexing mechanism has failed in multi-tenant shared scheme database. This paper proposed a multi-tenant distributed indexing mechanism. We create a global index first and then create the local index by MapReduce framework based on Hadoop. We also proposed the process of index update and index merging. Experimental r...

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...
