Starting from the PDCA cycle (Plan - Do - Check - Act), imposed by the ISO 9000 quality standards, a loop is proposed to automatically adjust the work equipment to the statistical distribution of the quality feature of the last N products randomly selected. The loop promptly warns the leadership in case of distortion of the statistical distribution...

Context 1
... Figure 2, the verification consists of measuring the quality of the product, depending on which action will be taken for improvement. Inevitably, factors (equipment, raw materials, human operator or environment) interfere with the process, which, through their variation, make the products of variable quality ...
Context 2
... current standard, concerning quality management systems, maintains the requirements of the old standards, but groups them logically on the technological flow. * https://doi.org/10. 1051/matecconf/201817808001 IManE&E 2018 The process-based approach incorporates the PDCA cycle, the requirements being grouped into 7 articles, corresponding to numbers 4 to 10 in Figure 1. The cycle Plan-Do- Check-Act is a typical automation loop, in which the Check-Act operations are a feedback that interferes with planning, in order to improve the quality of the product. Figure 2 only aims to redraw Figure 1, highlighting that the PDCA cycle is a typical automation loop. Since the standard [1] has a general nature, covering all activities in production and services, this paper aims to identify solutions for the "Improvement" module, so that through "Verification" and "Actuation", some operations from the quality management system of a production line can be ...

The determination of wind speed characteristics is extremely important for estimating the wind power output. In this context, Weibull distribution is one of the most commonly used statistical distributions for modeling wind speed. However, despite its widespread usage, it may not be accurate for modeling all wind regimes. For this reason, alternati...

We proposed a signal demodulation method by measuring the time interval between adjacent photons and realized the recovery of the original signal from the discrete random pulse sequence output by the single-photon detector. On this basis, a new communication system model is established by comprehensively considering the photon statistical character...

Damage theory studies the whole process of initiation, propagation, and instability of microcracks in materials and provides an important basis for the estimation of the risk of materials. Therefore, it is assumed that the rock microunit strength is the damage variable of the medium and obeys the Weibull distribution. According to the tensile failu...

The use of modern and ancient sedimentation systems as analogs of oil reservoir sand bodies has played a central role in the creation of realistic geological models. Analogs provide important information about the size, shape, heterogeneity of different scales, and potential connectivity of the bodies of natural hydrocarbon reservoirs. The facies m...

Variational autoencoders employ an encoding neural network to generate a probabilistic representation of a data set within a low-dimensional space of latent variables followed by a decoding stage that maps the latent variables back to the original variable space. Once trained, a statistical ensemble of simulated data realizations can be obtained by...
