Desenvolvimento de uma metodologia de implementação de RPA em processos de apoio à logística

Nos últimos anos, ocorreram diversas alterações nas organizações, derivadas pelos avan-ços tecnológicos, o que provoca um aumento da exigência dos clientes e, consequentemente, competitividade entre as organizações. A utilização das Tecnologias de Informação (IT) auxilia nas tarefas repetitivas, permitindo ao ser humano focar-se em tarefas essenciais. A literatura revela a falta de uma metodologia que permita auxiliar as organizações a implementar a Automação de Processos Robóticos (Robotic Process Automation, RPA) corre-tamente. Assim, a presente dissertação, tem como principal objetivo desenvolver uma meto-dologia nesse sentido. Deste modo, é realizada uma revisão de literatura, apresentando con-ceitos fundamentais da Indústria 4.0 e do seu desenvolvimento histórico, de RPA, de modelos de decisão e de ferramentas Lean e de Qualidade. Deste modo, com base nos conceitos revis-tos na literatura, foi proposto uma metodologia, dividida em 4 fases, que permite a correta implementação de RPA nas organizações. De forma a testar e validar a metodologia, foi realizado um estudo de caso na CEST-Comércio e Indústria, Lda. No estudo de caso, foi realizado o mapeamento dos seus processos empresariais, através da caracterização detalhada do sistema atual. Foi também desenvolvido um modelo de decisão, utilizando o Processo Hierárquico Analítico (Analytical Hierarchy Pro-cess, AHP), de modo a identificar o processo que deve ser automatizado inicialmente. Como proposta de automatização foi desenvolvido um robot de RPA através do software UiPath, associado ao processo de leitura e processamento das faturas de clientes e posterior introdução dos dados pretendidos num mapa de Excel. Os resultados obtidos demonstram que a implementação deste robot de RPA irá originar uma poupança no tempo de processamento de 62,8% e, consequentemente, uma poupança de 1,28 dias de trabalho, em média, por ano, para a tarefa em causa.In the last few years, several changes have occurred in organizations, derived from tech-nological advances, which caused an increase in customer demand and, consequently, com-petitiveness among organizations. The use of IT (Information Technology) helps in repetitive tasks, allowing human beings to focus on essential tasks. Literature reveals the lack of a methodology to help organizations to implement Robotic Process Automation (RPA) correctly. Thus, the main objective of this dissertation is to develop a methodology in this sense. Therefore, a literature review is performed, presenting fundamen-tal concepts of Industry 4.0 and its historical development, RPA, decision models and Lean and Quality tools. This way, based on the concepts reviewed in the literature, a methodology was proposed, divided into 4 phases, which allows the correct implementation of RPA in organiza-tions. To test and validate the methodology, a case study was carried out at CEST-Comércio e Indústria,Lda. In this case study, the mapping of its business processes was carried out, through the detailed characterization of the current system. A decision model was also developed, using the Analytical Hierarchy Process (AHP) method, to identify the organization's process that should be automated, in a first instance. As an automation proposal, an RPA robot was developed through the UiPath software, associated to the process of reading and processing customer invoices and the subsequent introduction of the required data in an Excel map. The results obtained show that the implementation of this RPA robot will lead to a saving in processing time of 62.8% and, consequently, a saving of 1,28 working days, on average, per year, for the task in question

Search for narrow resonances using the dijet mass spectrum in pp collisions at s√=8 TeV

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at s√=8  TeV. The data sample corresponds to an integrated luminosity of 4.0  fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall–Sundrum graviton model in the dijet channel

Search for ZZ ' resonances decaying to ttˉt\bar{t} in dilepton+jets final states in pppp collisions at s=7\sqrt{s}=7 TeV

A search for resonances decaying to top quark-antiquark pairs is performed using a dilepton+jets data sample recorded by the CMS experiment at the LHC in pp collisions at sqrt(s) = 7 TeV corresponding to an integrated luminosity of 5.0 inverse femtobarns. No significant deviations from the standard model background are observed. Upper limits are presented for the production cross section times branching fraction of top quark-antiquark resonances for masses from 750 to 3000 GeV. In particular, the existence of a leptophobic topcolor particle Z' is excluded at the 95% confidence level for resonance masses M[Z'] < 1.3 TeV for Gamma[Z'] = 0.012 M[Z'], and M[Z'] < 1.9 TeV for Gamma[Z'] = 0.10 M[Z']

Measurement of the Drell-Yan Cross Section in pp Collisions at s\sqrt{s} = 7 TeV

The Drell-Yan differential cross section is measured in pp collisions at sqrt(s) = 7 TeV, from a data sample collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 36 inverse picobarns. The cross section measurement, normalized to the measured cross section in the Z region, is reported for both the dimuon and dielectron channels in the dilepton invariant mass range 15-600 GeV. The normalized cross section values are quoted both in the full phase space and within the detector acceptance. The effect of final state radiation is also identified. The results are found to agree with theoretical predictions.The Drell-Yan differential cross section is measured in pp collisions at sqrt(s) = 7 TeV, from a data sample collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 36 inverse picobarns.

Search in leptonic channels for heavy resonances decaying to long-lived neutral particles

A search is performed for heavy resonances decaying to two long-lived massive neutral particles, each decaying to leptons. The experimental signature is a distinctive topology consisting of a pair of oppositely charged leptons originating at a separated secondary vertex. Events were collected by the CMS detector at the LHC during pp collisions at $\sqrt{s}$ = 7 TeV, and selected from data samples corresponding to 4.1 (5.1) inverse femtobarns of integrated luminosity in the electron (muon) channel. No significant excess is observed above standard model expectations, and an upper limit is set with 95% confidence level on the production cross section times the branching fraction to leptons, as a function of the long-lived massive neutral particle lifetime.A search is performed for heavy resonances decaying to two long-lived massive neutral particles, each decaying to leptons.

Measurement of the W+W- cross section in pp collisions at sqrt(s) = 7 TeV and limits on anomalous WW gamma and WWZ couplings

A measurement of W+W- production in pp collisions at sqrt(s) = 7 TeV is presented. The data were collected with the CMS detector at the LHC, and correspond to an integrated luminosity of 4.92 +/- 0.11 inverse femtobarns. The W+W- candidates consist of two oppositely charged leptons, electrons or muons, accompanied by large missing transverse energy. The W+W- production cross section is measured to be 52.4 +/- 2.0 (stat.) +/- 4.5 (syst.) +/- 1.2 (lum.) pb. This measurement is consistent with the standard model prediction of 47.0 +/- 2.0 pb at next-to-leading order. Stringent limits on the WW gamma and WWZ anomalous triple gauge-boson couplings are set
