Analýzu výrobního informačního systému MES Hydra a následná optimalizace ve zvolené společnosti / Analysis of the MES Hydra Production Information System and Subsequent Optimization in the Selected Company

Voborný, Vojtěch January 2017 (has links)
The thesis focuses on the analysis of the processing informational system MES Hydra used by automotive company Jopp Automotive s. r. o.. Since the company does not use full potential of the described system, emphasis will be placed especially on the modules involved in the production process. The analysis will be carried out by user's perspective and also the actual implementation and suggestions about possible improving of user´s interface or potential application of additional options of the system will be considered. The integral part of the thesis are production schemes, on that facts and ideas for process optimalization controlled by the system will be discussed.

Proposta de um modelo de sistema MES sob a ótica de recurso estratégico para a gestão da produção em uma empresa de manufatura de autopeças

Bochi, Marco Antonio Marques 25 September 2008 (has links)
Made available in DSpace on 2015-03-05T18:40:06Z (GMT). No. of bitstreams: 0 Previous issue date: 25 / Nenhuma / A competição a nível mundial obrigou as empresas de manufatura a reformularem os seus modelos gerenciais e seus sistemas produtivos , visando uma melhor utilização dos recursos da produção e uma elevação na sua eficiência operacional para atingir uma vantagem competitiva sustentável. Diante deste contexto, esta pesquisa apresenta a proposta de um modelo descritivo de sistema MES (Manufacturing Execution System) visto como um recurso sob o enfoque da Teoria da Visão Baseada em Recursos, para a aplicação na gestão da produção de uma empresa de manufatura de lonas de freios para veículos pesados. O seu desenvolvimento segue o método da pesquisa-ação, através da adaptação de um modelo de uma pesquisa anterior, incluindo uma fase de diagnóstico, na qual se realiza um levantamento da situação da organização sob estudo, uma fase de aprendizado externo, realizada em outra empresa com o objetivo de se aprender sobre o seu processo de seleção e implantação de sistema similar e uma fase de planejamento da ação, que apr / The worldwide competition forced manufacturing companies to reformulate their managerial models and production systems, seeking for a better use of production resources and an increase in their operational efficiency to achieve a sustainable competitive advantage. In front of this context this research presents a proposal of a descriptive model of a MES system (Manufacturing Execution System), seem as a resource under the focus of the Resource-Based View theory, for implementation in the production management of a brake linings manufacturing company for heavy vehicles. Its development follows the action research method, by adapting a model of a previous research, including a diagnosis stage, which makes an assessment about the situation of the organization under study, a stage about external learning, held in another company with the objective to learn about its process of selection and deployment of a similar system and a stage of action planning which presents the description of a model to be deployed in th

Studie operativního řízení výroby ve vybrané firmě / The Study of Operational Production Management in Selected Firm

Černohousová, Pavla January 2012 (has links)
This thesis studies the operational management of production, particularly the divison of plastic mill. The study analyses current state of operational management of production and especially focus on physical and information flow. Based on the results of the analysis, study eliminates discovered defects. For that reason, design part is focused on optimization of informational flow by introduction of modular manufacturing information system. At the end of the thesis are presented benefits of mentioned solution and economic evaluation for the proposed options.

Development and Evaluation of a Machine Vision System for Digital Thread Data Traceability in a Manufacturing Assembly Environment

Alexander W Meredith (15305698) 29 April 2023 (has links)
<p>A thesis study investigating the development and evaluation of a computer vision (CV) system for a manufacturing assembly task is reported. The CV inference results are compared to a Manufacturing Process Plan and an automation method completes a buyoff in the software, Solumina. Research questions were created and three hypotheses were tested. A literature review was conducted recognizing little consensus of Industry 4.0 technology adoption in manufacturing industries. Furthermore, the literature review uncovered the need for additional research within the topic of CV. Specifically, literature points towards more research regarding the cognitive capabilities of CV in manufacturing. A CV system was developed and evaluated to test for 90% or greater confidence in part detection. A CV dataset was developed and the system was trained and validated with it. Dataset contextualization was leveraged and evaluated, as per literature. A CV system was trained from custom datasets, containing six classes of part. The pre-contextualization dataset and post-contextualization dataset was compared by a Two-Sample T-Test and statistical significance was noted for three classes. A python script was developed to compare as-assembled locations with as-defined positions of components, per the Manufacturing Process Plan. A comparison of yields test for CV-based True Positives (TPs) and human-based TPs was conducted with the system operating at a 2σ level. An automation method utilizing Microsoft Power Automate was developed to complete the cognitive functionality of the CV system testing, by completing a buyoff in the software, Solumina, if CV-based TPs were equal to or greater than human-based TPs.</p>
