The efficiency and robustness of reliability methods are two important factors in the first-order reliability method (FORM). The conjugate choice control (CCC) and directional chaos control method (DCC) are developed to improve the robustness and efficiency of the FORM formula using the stability transformation method. In this paper, the CCC and DCC methods are applied for the reliability analy...

Children with complex chronic conditions (CCC) belong to a distinct pediatric group, characterized by the (potential) manifestation of wide range pathologies requires long-term multidisciplinary health care, alongside recurrent hospitalizations and, in many cases, dependent on use technology for life maintenance. The need seek, organize and disseminate bibliographic information CCC led us chart...

The fuzzy regression control chart is a functional technique to evaluate the process in which the average has a trend and the data represents a linguistic or approximate value. In this study, the theoretical structure of the “α-level fuzzy midrange for α-cut fuzzy X ~ -regression control chart” is proposed for triangular (TFN) and trapezoidal (TrFN) membership functions. In addition, the real w...

Statistical Process Control (SPC) is used to monitor the process stability which ensures the predictability of the process. In 1920‟s Shewhart introduced the control chart techniques that are one of the most important techniques of quality control to detect if assignable causes exist. The widely used control chart techniques are R X  and S X  . These are called traditional variable control ch...

 Recently several control charts have been introduced in the  statistical process control  literature which are based on the idea of Bayesian Predictive Density (BPD).  Among these charts is the variation control chart which we refer to it as VBPD chart. In this paper we add the idea of Moving Average to VBPD chart and introduce a new variation control chart which has all advantages of the ...

Consider a mass production of HDD arms where hundreds of CNC machines are used to manufacturer the HDD arms. According to an overwhelming number of machines and models of arm, construction of separate control chart for monitoring each HDD arm model by each machine is not feasible. This research proposed a strategy to optimize the SPC management on shop floor. The procedure started from identify...
