Approche sémantique de gestion de ressources d’Information pour le contrôle de processus industriels : application au processus de fabrication chez STMicroelectronics / A semantic approach for resource description and retrieval for the manufacturing process control : application to the process control within STMicroelectronics

Bouzid, Sara 06 December 2013 (has links)
Afin d’assurer la fabrication de produits conformes et à faible coût dans les industries, la maîtrise des procédés de fabrication est devenue un enjeu majeur. Les systèmes d'information dans les industries sont assez complexes et les besoins métier évoluent en permanence, rendant ainsi difficile la recherche des ressources qui fournissent les informations manufacturières pour le contrôle de procédés industriels. De plus, l’utilisation de plateformes logicielles commerciales dans les industries pour le traitement des données ne facilite pas l’accès à l’information produite car ces plateformes ne permettent pas la gestion sémantique de l’information. Cette thèse défend l’idée qu’il faut réduire la distance entre les ressources disponibles et les besoins métier des experts qui assurent le contrôle de processus industriels. L’approche S3 est proposée pour permettre à la fois la description et la recherche de ces ressources. S3 repose sur deux stratégies de recherche complémentaires: une stratégie ascendante permettant la création de descripteurs sémantiques de ressources, et une stratégie descendante permettant la capture des besoins métier dans des patterns de recherche. Deux structures sémantiques sont proposées pour supporter les mécanismes de description et de recherche: une ontologie « manufacturing process » et un dictionnaire « process control ». Chaque stratégie de recherche, appuyée par les structures sémantiques apporte un niveau de description différent et permet l’alignement de différents types de connaissances métier. Cette approche a été expérimentée au sein de l’entreprise STMicroelectronics et a révélé des résultats prometteurs. / In order to ensure the manufacturing of conforming products with the least waste, the manufacturing process control has ever more become a major issue in industries nowadays. The complexity of the information systems in industries and the permanent evolution of the business needs make difficult the retrieval of the resources that provide manufacturing information related to the process control. In addition, the use of commercial software platforms in industries for the processing of data, does not facilitate the access to the information produced, because these platforms do not support the semantic management of information.This thesis argues the need to reduce the distance between the used resources in industries and the business needs of the experts that ensure the control of the manufacturing processes.The S3 approach is proposed to support the control of the manufacturing processes through an original resource management system. This system is intended for both resource description and retrieval. The S3 approach relies on two complementary retrieval strategies: a bottom-up strategy enabling the creation of semantic descriptors of resources, and a top-down strategy enabling the capture of business needs in search patterns. Two semantic structures are proposed to support the resource description and retrieval mechanisms: a manufacturing process ontology and a process control dictionary. Basing on these semantic structures, each retrieval strategy provides different levels of description to the resources, and enables the alignment of different types of business knowledge. The experimentation of the approach within STMicroelectronics showed promising results.

Rozbor parametrů výrobních zakázek ve společnosti NATE - nápojová technicka a. s. za období 2002 - 2012 / An analysis of the production parameters of the products of a company NATE-nápojová technika a.s. for the period 2002-2012

Klepetková, Iva January 2012 (has links)
This thesis deals with an analysis of the production parameters of the two main products of a company NATE-nápojová technika a.s. for the period 2002-2012. Based on the theoretical fundamentals of production management and purchasing process. It analyzes each product from the customer's territory, production deadlines, cost and productivity. Based on this analysis are revealed weak points in the production and the purchase process and try to find ways to resolve them.

Tvorba výrobní koncepce pro plánování výrobního procesu / Making Production Concept for Planning of the Production Process

Mňuková, Eliška January 2021 (has links)
This diploma thesis is focused on examining the activities of production planning and examining the efficiency of the selected machine in the selected company. The theoretical part summarizes the most important findings and methods of lean manufacturing and corrective measures to prevent or eliminate downtime. In the analytical part, the selected machine is examined in terms of the production process, then an analysis of the current state and assessment of the collected data is performed. Furthermore, an analysis of the decision-making process in production planning for a selected machine was performed and shortcomings in planning were assessed. The practical part contains suggestions for removing the identified bottlenecks.

Výroba držáku mobilního telefonu / Manufacturing of the Mobile Phone Holder

Hřebíček, Robert January 2017 (has links)
The master´s thesis is focused on the manufacture of mobile phone holder. The semi-finished productis a 1.5 mm thick steel sheetroll of S235JRG1. The annual seriesis set at 200,000 units per year. For the production of the part, the method of shearing and bending in a combined tool was chosen. Both technologies were dissected in a literary study, and a production process was developed to design a tool. A suitable production line was purchased for the entire production and the suitability of production was economicallye valuated.

The paper starts on foregoing work of design team leading to a proposed model and material. Both material and model are investigated form a manufacturing point of view. Cutting conditions and milling strategy are proposed based on final product analysis. Prototype was manufactured on CNC machining centre MCV 754 QUICK in company BOSCH DIESEL s.r.o. in Jihlava. Retrospective analysis of performed manufacturing process and critical risks is provided with a proposal of more effective manufacturing process. In the closure, there is technical-economical evaluation of chosen manufacture done by milling. Alternative manufacturing options including 3D print and welding are compared in technics and costs.
