Aplicación de metodología seis sigma para disminuir intervenciones en proceso de fabricación de vidrios

Este trabajo se realizó con la finalidad de reducir el tiempo promedio de intervenciones de un proceso de corte mecánico de vidrio en una importante empresa manufacturera de la región. La metodología utilizada consideró la aplicación de la metodología Seis Sigma y especialmente la implementación del ciclo de procesos DMAMC, propio de esta metodología.Para el análisis estadístico de los datos se utilizaron  herramientas de control de procesos y la utilización del software Minitab como ayuda al proceso de procesamiento y análisis de datos.La situación problema bajo estudio estaba relacionada con la observación de una alta cantidad de intervenciones humanas sin una justificación técnica de ellas, con la consiguiente reducción de la productividad del personal técnico operativo involucrado en el proceso de corte de vidrio. La situación problema poseía el respaldo de la alta dirección de la empresa, dado que el comportamiento del personal técnico operativo no era similar al observado en otras plantas de similar naturaleza.Para el desarrollo de la metodología se identificaron problemas prioritarios, estableciéndose métricas para cada uno de ellos. Los resultados obtenidos, producto de la aplicación del ciclo DMAMC,  permitió identificar Procesos, Actividades y Horas del día críticos, y para cada uno de ellos se estableció un plan de mejoras. Los resultados alcanzados, luego de cuatro meses de seguimiento de las mejoras implementadas, indican que fue posible cumplir y sobrepasar las metas establecidas identificando con mayor precisión las conductas del personal en el proceso de corte de vidrio, las  necesidades de inversión tecnológica , actuales y potenciales  y la identificación de aquellos aspectos de gestión que posibilitan la implementación exitosa de la metodología adoptada.This work was realised in order to reduce to the time average of interventions of a glass cuts process in an important manufacturing company of the region. The used methodology considered the application of Six Sigma methodology and the implementation of DMAMC cycle processes. For the statistic analysis were used for the data analysis process the Minitab software.The problem situation under study was related to the observation of a high amount of human interventions without a technical justification of them, with the consequent reduction of the productivity level of the operative technical personnel involved in the glass cuts process . The situation problem owned the endorsement of the high management of the company since the behaviour of the technical operative personnel was not similar to the observed in other plants of similar process.

The DUNE Far Detector Vertical Drift Technology, Technical Design Report

International audienceDUNE is an international experiment dedicated to addressing some of the questions at the forefront of particle physics and astrophysics, including the mystifying preponderance of matter over antimatter in the early universe. The dual-site experiment will employ an intense neutrino beam focused on a near and a far detector as it aims to determine the neutrino mass hierarchy and to make high-precision measurements of the PMNS matrix parameters, including the CP-violating phase. It will also stand ready to observe supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector implements liquid argon time-projection chamber (LArTPC) technology, and combines the many tens-of-kiloton fiducial mass necessary for rare event searches with the sub-centimeter spatial resolution required to image those events with high precision. The addition of a photon detection system enhances physics capabilities for all DUNE physics drivers and opens prospects for further physics explorations. Given its size, the far detector will be implemented as a set of modules, with LArTPC designs that differ from one another as newer technologies arise. In the vertical drift LArTPC design, a horizontal cathode bisects the detector, creating two stacked drift volumes in which ionization charges drift towards anodes at either the top or bottom. The anodes are composed of perforated PCB layers with conductive strips, enabling reconstruction in 3D. Light-trap-style photon detection modules are placed both on the cryostat's side walls and on the central cathode where they are optically powered. This Technical Design Report describes in detail the technical implementations of each subsystem of this LArTPC that, together with the other far detector modules and the near detector, will enable DUNE to achieve its physics goals

Performance of a modular ton-scale pixel-readout liquid argon time projection chamber

International audienceThe Module-0 Demonstrator is a single-phase 600 kg liquid argon time projection chamber operated as a prototype for the DUNE liquid argon near detector. Based on the ArgonCube design concept, Module-0 features a novel 80k-channel pixelated charge readout and advanced high-coverage photon detection system. In this paper, we present an analysis of an eight-day data set consisting of 25 million cosmic ray events collected in the spring of 2021. We use this sample to demonstrate the imaging performance of the charge and light readout systems as well as the signal correlations between the two. We also report argon purity and detector uniformity measurements, and provide comparisons to detector simulations
