Maximization of profitability occurs fundamentally through the reduction of manufacturing cost, which represents, in general, 20% of the final cost of the product, where the remaining relates to components and raw materials. The manufacturing costs can be reduced through the elimination of losses and rationalization of flow of the production process, with application of knowledge management in achieving improvement and innovations for necessary adaptation ahead of internal (industrial) and external (market) changes. It’s a fact that, the assembling of most parts of electronic products involve a process of various stages, the purpose of the research was the bottleneck stage of the process which relies on resources of significant values and highly skilled operators. Even with all its significance to the production chain many weaknesses were identified which were not perceived based on realities of the past. These points were corrected with application of the proposed methodology and the results prove the relevance of the MES tool for development and consolidation of the organizational competitiveness. / Essa pesquisa mostra o uso do Sistema Manufacturing Execution Systems (MES) na aplicação sistêmica da Gestão do Conhecimento em uma empresa de manufatura de produtos eletrônicos, inserida em um ambiente de competitividade crescente com inovações tecnológicas frequentes. Esse quadro gera instabilidade no mercado devido ao fato de produtos e serviços apresentarem ciclo de vida cada vez menores, de consumidores serem mais exigentes, de haver demandas instáveis num contexto de pequena rentabilidade, o que caracteriza um comportamento de organizações complexas e adaptativas. A maximização da rentabilidade ocorre fundamentalmente através da redução do custo de manufatura, pois esse item representa, em geral, 20% do custo final do produto, ao passo que o restante refere-se a componentes e insumos commodities. Tal redução apresenta como pressupostos a eliminação de perdas e a racionalização do fluxo do processo produtivo, com aplicação da gestão do conhecimento na obtenção de melhorias e inovações para as adaptações necessárias diante das mudanças internas (fabril) e externas (mercado). Em decorrência de a montagem de grande parte dos produtos eletrônicos apresentarem um fluxo de processos com várias etapas, o objeto da pesquisa foi a fase gargalo do processo que conta com os recursos de valores expressivos e operadores mais capacitados. Mesmo com toda essa significância para a cadeia produtiva identificaram-se muitos pontos frágeis, antes despercebidos, com base na realidade anterior. Tais pontos foram corrigidos com a aplicação da metodologia proposta, com os resultados comprovando a relevância do uso da ferramenta MES para o desenvolvimento e consolidação da competitividade da organização.

A tool management system for a job shop was developed in this study. The system is based on the rules of the plant of T&uuml / rk Trakt&ouml / r ve Ziraat Makineleri A.S. in Ankara. An object-oriented methodology was used during the system development. Unified Modeling Language (UML), which is the standard diagramming notation for object-oriented development, is used to model the system. Entity-Relation (E-R) modeling is used during the construction of the database. System was developed using three-tiered Microsoft Windows Distributed Internet Applications (DNA) Architecture. Microsoft Visual Basic 6.0 and Visual InterDev 6.0, which are the members of Microsoft Visual Studio 6.0 were used as programming tools. Internet Information Server was used as web server and Microsoft Transaction Server was used as object broker. Microsoft SQL Server was used as database server. Software was developed in three modules: gage-fixture, cutting tool-tool holder and tool requirement plan modules. Gage- fixture module tracks the location of measuring equipment, fixture and fixture assemblies / keeps the related data about these tools and manage calibration of the measuring equipments. Cutting tool-tool holder module tracks the issue and return of cutting tools and tool holders / sharpening of cutting tools / keeps the related data about these tools. Tool requirement plan module tracks the purchase orders and cutting tool receivings from vendors / prepares tool requirement plan and suggests purchase orders according to the requirement calculation.

The effective use of information system MES (Manufacturing Execution System) in the food company is the main topic of this master's thesis. The modularly built system provides valuable support of the production process on operational level. The thesis concentrates on the analysis of already implemented standard solution in the company's factory. Main goal is to propose expansion of the functioning area to the already existing solution, aiming for effective use of energy resources. It was necessary, in order to be able to achieve the goal, to get familiar with the complex corporate IT/ICT construction in alignment with the company's energy concept. The proposed solution is leaning on application of internal MES project methodology, leading to exact specification of energy component in the factory production frame. The thesis conclusions, besides the proposed solution itself should serve as an argument about the efficiency of starting MES system in other production factories of the company.

Artificial Intelligence arises in the manufacturing field very rapidly. Implementing Artificial Intelligence (AI) solutions and algorithms in the manufacturing environment is a well-known research field in academia. On the other hand, Manufacturing-Execution-System (MES) providers do not have a theoretical and pragmatic framework regarding the evaluation of MES functions in respect to their suitability for Artificial Intelligence. In order to be able to pre-evaluate whether a MES function shall be AI supported an intense literature research has been conducted. Academia shows few investigations regarding this field of research. Recent studies have been concerning about possible applications for MES functions in combination with AI. However, there is a lack of research in terms of pre-evaluating a MES function before embedding the function with AI support, since the development of AI solutions for MES functions without pre-evaluating those bears a waste of valuable resources. Therefore, the thesis work introduces an assessment framework consisting of decisive criteria and related indicators which describe qualitatively the suitability of AI for MES functions based on three criteria with related indicators. In addition, the researcher displays furthermore how the developed assessment framework can be used in order to assess the MES functions regarding their AI “readiness”. In order to cope the findings through the thesis work an inductive research approach has been applied. Existing literature in the fields of intelligent manufacturing, Manufacturing-Execution-Systems, machine learning, deep learning, intelligent manufacturing, digital twin, and assessment methodologies have been extensively studied in order to base the theoretical developed framework on grounded theory. A major issue was to focus the development of the assessment framework in harmony with academia and industry. The requirements for academia were met by providing profoundly investigation through the research fields. A case study was carried out in order to test the validity and reliability of the developed assessment framework for industry. The outcome of this thesis work was an assessment framework consisting of decisive criteria and related indicators when evaluating a MES function in respect to its AI suitability. Furthermore, an assessment checklist has been provided for the industry in order to be able to assess a MES function regards AI support in a quick and pragmatic manner. To generate a more generalizable assessment framework criteria and indicators have to be adapted, likewise testing the outcome of analogue and digital assessment methodologies will provide material for future studies. / <p>Successfully defended</p>

The priorities of executing the manufacturing orders generated by an MRP system are often in operational conflicts with the dynamics of the manufacturing floor. It is not uncommon for a given manufacturing order to reach the shop floor several weeks or longer after being "opened" by an MRP system where it may face a chaotic case of large queues, machine down-time, parts shortage, scrap problems and other resource management constraints. Many companies have resorted to the Manufacturing Execution System (MES) software solution to resolve these problems. This method first gained popularity in mid-90’s within the semiconductor industry. An MES approach is an on-line, real-time data gathering, analysis and storage to assist in short-interval scheduling (shift or day) manufacturing operations with an emphasis on revising scheduling priorities. It is essentially an information system tool for the shop floor and if designed properly, it may be used as an advisory system for effective decision-making. However, in implementation MES faces several challenges including the proper software platform/architecture, integration within ERP or a stand-alone best-of-breed, amount and type of data/information to be exchanged with the MRP engine, and a user-centered interface for various layers of decision making. This paper will provide a detailed background on various technical, software, and organizational factors that the use of an MES implementation may impose upon the practitioner. Furthermore, and as a case study, it will discuss a systematic implementation strategy for MES at a high-tech company in California. The discussion of the critical success factors in implementation planning will hopefully be of value to both practitioners and researchers in similar projects.

The increasing importance of computer leads to develop new manufacturing methods. One of the most important example / &ldquo / unmanned shop floor&rdquo / model aims, the mankind can work in jobs that they can be more efficient and more comfortable. As the base of this model, in Middle East Technical University Computer Integrated Manufacturing Laboratory (METUCIM) &ldquo / Agent Version 1.1&rdquo / system is developed. Windows Distributed Internet Applications (DNA) modeling technique is used for the software development. In the developed system, by using web pages, one can give work orders to the flexible manufacturing cell in METUCIM. The manufacturing capabilities of the cell are limited by the capabilities of CNC Lathe and CNC Milling machine that exist in the system. By the developed agent based dynamic scheduling method, it is prevented to be only an experimental system for the manufacturing cell. The real manufacturing environment is adapted to the cell that it is possible to give unlimited number of work orders. The work orders can be queued and manufactured according to their &ldquo / priorities&rdquo / . By the &ldquo / web-cam&rdquo / application the given work orders can be watched from the web site so the system reliability is increased for the engineer. In the real manufacturing environment it is very frequent that the &ldquo / urgent part&rdquo / is needed to manufacture. In this system it is possible to give &ldquo / urgent orders&rdquo / for these situations.

Det här examensarbetet har utförts på Scania CV AB:s motorbearbetningsavdelning i Södertälje. I dagsläget pågår en omställning av tillverkningsprocessen på avdelningen där två nya tillverkningslinor, en för cylinderblock och en för cylinderhuvud, är under uppbyggnad. Linorna kommer styras med hjälp av ett Manufacturing Execution System. Ett Manufacturing Execution System har i uppgift att samla in data och information från tillverkningsprocessen, som sedan kan presenteras i ett gränssnitt. Vilken information som kommer finnas tillgänglig att presentera i systemet styrs utifrån en intern kravspecifikation som ska spegla International Society of Automation:s standard, även känd som ISA-95. Den kravspecifikation som finns för systemet är framtagen av IT-avdelningen i samråd med avdelningschefer. För närvarande är det osäkert om kravspecifikationen som finns på systemet stämmer överens med vad medarbetarna behöver för att kunna arbeta på ett effektivt sätt. Det här arbetet kartlägger behovet hos medarbetarna och jämför det med den befintliga kravspecifikationen. Genom intervjuer och enkäter har den befintliga kravspecifikationen för systemet jämförts med vad medarbetarna anser vara önskvärda funktioner i systemet. Resultatet av den första omgången intervjuer och enkätutskick var att kravspecifikationen och behovet hos medarbetarna stämmer väl överens. Det mynnade ut i att ytterligare en enkät skickades ut där medarbetarna istället skulle rangordna den information som kommer finnas tillgänglig i systemet utefter en prioriteringsskala i tre nivåer. Resultatet från den enkäten gav en bild av vilken information medarbetarna tycker är viktigast för att kunna arbeta på ett effektivt sätt. / This bachelor thesis has been done at Scania CV AB’s department for engine manufacturing in Södertälje. The manufacturing process at the department is currently under development, where two new lines are being added, one for cylinder head and one for cylinder blocks. These two new manufacturing lines are going to be controlled with the help of a Manufacturing Execution System. The Manufacturing Execution Systems task is to collect data and information from the manufacturing process, which later can be presented in an interface. There is a specification at Scania that presents what information will be available in the system. That specification is in line with what the International Society of Automation has specified in ISA-95. The specification for the system was set by the IT-department in consultation with department managers. There is currently an uncertainty if the specification meets the requirement that the workers has, to be able to work efficiently with the system. This thesis will identify the requirement that the workers has on the system, and compare it with the current specification. What the workers deems is necessary information has been identified and mapped through interviews and a survey. The result of these interviews and the survey made it clear that the specification was well in line with the requirement from the workers. This information led to the decision to send out another survey that asked the workers to prioritize how important the information in the system is, in three different priority levels. This resulted in an overview of what the workers consider is the most important information in the system.
