The textile sector has a large share in the Peruvian manufacturing industry, dominated by SMEs. However, the segment has been facing a slowdown in growth, intensified by the partial inoperability of ...commercial enterprises. Under this scenario, there is a need to improve its competitiveness by optimizing the material supply process, as this is the stage that generates a large number of non-conforming orders and delays in the entry of production. Therefore, an optimize model using Just-In-Time and Lean Warehouse has been proposed to reduce backorders, shorten delivery times and minimize the input of defective materials. Along with 5S methodology to organize the warehouse and supplier assessment, ensured a long lasting solution. After the simulation made by the software Arena with the proposed model, it was possible to reduce the number of non-optimal orders by 55% and increase process efficiency by 5.97% by reducing procurement lead time. Furthermore, it represents a reduction in the purchasing cost of 40.55%.
The gluon polarization in the nucleon was measured using open charm production by scattering 160 GeV/c polarized muons off longitudinally polarized protons or deuterons. The data were taken by the ...COMPASS Collaboration between 2002 and 2007. A detailed account is given of the analysis method that includes the application of neural networks. Several decay channels of D super(0) mesons are investigated. Longitudinal spin asymmetries of the D meson production cross sections are extracted in bins of D super(0) transverse momentum and energy. At leading order QCD accuracy, the average gluon polarization is determined as left angle bracket Delta g/gright angle bracket super(LO) = -0.06 + or - 0.21(stat.) + or - 0.08(syst.) at the scale left angle bracket mu super(2)right angle bracket approx = 13 (GeV/c) super(2) and an average gluon momentum fraction left angle bracketxright angle bracket approx = 0.11. The average gluon polarization is also obtained at next-to-leading order QCD accuracy as left angle bracket Delta g/gright angle bracket NLO = -0.13 + or - 0.15(stat.) + or - 0.15(syst.) at the scale left angle bracket mu super(2)right angle bracket approx = 13 (GeV/c) super(2) and left angle bracketxright angle bracket approx = 0.20.
