Proposta de metodogia de engenharia de domínio para o desenvolvimento de sistemas de automação industrial

Kipper, Marcelo Mondadori January 2010 (has links)
Engenharia de domínio (do inglês: DE - Domain Engineering) é uma proposta surgida no âmbito da Engenharia de Software e que visa o aumento do reuso no desenvolvimento de sistemas, buscando uma redução dos custos e do tempo de desenvolvimento. A aplicação desta técnica em sistemas de automação industrial (produtos e plantas industriais) – os quais incluem múltiplas disciplinas (sistemas mecânicos, elétricos, pneumáticos, entre outros), diferentemente da engenharia de Software que trata basicamente do reuso de artefatos de Software – vem despertando o interesse de algumas instituições de pesquisa, como o IAS (Instituto de Automação Industrial e Engenharia de Software da Universidade de Stuttgart), e será abordada neste trabalho. A engenharia de plantas industriais é crescentemente realizada nas chamadas ferramentas de gerenciamento de ciclo de vida de plantas PLM (Plant ou "Production Lifecycle Management"), que se originou do conceito de "Product Lifecycle Management", cuja sigla também é PLM. A idéia destas ferramentas é o gerenciamento de ativos não somente durante o processo de engenharia, mas também durante a operação e manutenção até o descomissionamento das plantas. Muitas destas ferramentas PLM englobam o paradigma de orientação a objetos da Engenharia de Software, e baseadas neste paradigma, abordam a integração de dados entre os artefatos das várias disciplinas. Este trabalho apresenta o conceito de um artefato técnico reutilizável multidisciplinar, que foi a base para a elaboração de uma metodologia de engenharia de Domínio adaptada a ferramentas PLM, que se baseiam no paradigma de orientação a objetos. A metodologia proposta foi validada experimentalmente em um estudo de caso de uma Planta Modular de Produção (MPS – Modular Production System) em conjunto com a ferramenta PLM Comos da Siemens. Os resultados obtidos indicam a viabilidade da implementação da metodologia proposta em projetos na indústria, visando a redução de custo e tempo de desenvolvimento através do reuso de artefatos técnicos multidisciplinares em domínios com aplicações semelhantes. / Domain Engineering comes from the Software field and aims the increase of reuse to allow reduction of cost and time in the development of systems. The deployment of this methodology in automation systems (products and industrial plants) – in which more disciplines (mechanical, electrical, pneumatic, among others) are present and therefore differs from the Software engineering, that deals basically with the reuse of Software artifacts – has awakened the interest of some research institutes, like the IAS (Institute of Industrial Automation and Software Engineering of the University of Stuttgart), and will be analyzed during this work. The engineering of industrial plants is increasingly executed using the so called PLM Tools ("Plant or Production Lifecycle Management"), whose concept was originated from "Product Lifecycle Management", also abbreviated as PLM. The idea of these tools is to manage the assets not only in the engineering process, but also through operation and maintenance until the decommissioning of the industrial plants. Many of these PLM Tools support the object orientation principle from the Software engineering, and based upon this principle they address the integration of data from artifacts of the various disciplines. This work presents a concept for a multidisciplinary reusable technical artifact that was the base for the elaboration of an adapted DE Methodology for PLM Tools, in which the object oriented principle, is present. The presented ideas have been experimentally validated using as a case study a Modular Production System (MPS) together with the PLM Tool Comos from the company Siemens. The obtained results indicate a feasible implementation of the proposed methodology in the industry, aiming cost and time reduction through the reuse of multidisciplinary technical artifacts in domains with similar applications.

Análise da implantação de um sistema de gestão do ciclo de vida do produto no processo de desenvolvimento de produtos de uma empresa de tecnologia : um estudo de caso

Fachinello, Tatiana January 2006 (has links)
Os sistemas de Gestão do Ciclo de Vida do Produto (Product Lifeclycle Management – PLM), apesar de serem de suma importância no Processo de Desenvolvimento de Produtos (PDP) para que as empresas enfrentem as novas condições de sobrevivência no mercado atual, ainda não são plenamente conhecidos. Além disso, existem poucos trabalhos científicos relacionados à implantação deste tipo de sistemas durante o Processo de Desenvolvimento de um novo produto na empresa. Neste trabalho, realizou-se a análise da implantação de um sistema PLM no PDP de uma empresa de tecnologia através de: (i) levantamento do estado da arte sobre sistemas PLM, segundo a literatura, incluindo a apresentação dos modelos de referência e a integração das informações neste tipo de sistemas; (ii) comparativo entre as funções e tecnologias de sistemas de gestão do ciclo de vida do produto encontrados na bibliografia com os de um caso de implantação real e (iii) levantamento de quais funcionalidades e tecnologias presentes na implantação real de um sistema PLM (Product Lifecycle Management) suprem os requisitos de gestão do ciclo de vida do produto na empresa, para caracterizar um projeto de implantação real de um sistema PLM no PDP de uma empresa de tecnologia. / The Product Lifecycle Management (PLM) Systems, although being a imperative request to allow companies to develop new products, facing the new survival conditions in the current market, are not very well-known. Besides that, there are few scientific works related to the implementation of this kind of system and its usage in a Product Development environment. The objectives of this work are: (i) to rise, according with the bibliography, the state of the art of PLM systems, (ii) to rise, according to the bibliography, the functionalities and technologies requirements of a PLM system in a Product Development Process (PDP) environment and to compare those requirements with a real implementation case and (iii) to rise which funcionalities and technologies of PLM (Product Lifecycle Management) systems supply the founded needs to characterize a project of a real PLM system implementation in a Product Development Process environment.

Strategic ambiguity in corporate sustainability communications

Scandelius, Christina January 2014 (has links)
Purpose: The aim of this thesis is to develop a better understanding on how businesses should communicate their sustainability strategy to their stakeholders. Businesses are facing the challenge of designing sustainability communications strategies that appeal to stakeholders of various interest and knowledge on the topic, and stakeholders whose objectives might even be contradictory to that of the company. In order to facilitate the communications process to encourage a better uptake of sustainability initiatives by corporations and the public, it is essential to find solutions to these communications challenges. Methodology: The study focuses on the food and drink value chain in Western Europe and is based on empirical evidence from a multiple case study methodology involving in-depth interviews with 25 senior managers and directors from food and drink manufacturing companies, retailers, and some of their stakeholders. Findings: A framework for corporate sustainability communications is developed, depicting five communications strategies. The framework also offers an insight how stakeholders can be categorised into the most appropriate communications strategy through the application of certain segmentation attributes. It is further illustrated how the application of strategic ambiguity can add value to the communications process in order to stimulate interest, initiatives and innovation from stakeholders. Theoretical and practical implications/originality: Previous research on corporate communications strategies, has seen limited empirical validation, is primarily focussed on consumers, and more importantly is lacking in advice regarding how to craft communications that not only appeal to a multitude of stakeholders, but that also encourage collaboration. The findings therefore add confirmation and extension to the previous research and, importantly, it provides a link between theories of strategic ambiguity and the corporate communications literature. The framework also offers practical value as it provides managers with a clear guidance on how to design effective corporate sustainability communications, ensuring diverse appeal and/or engagement for collaboration. Thus it provides a tool that has the potential of facilitating holistic sustainability progress in a value chain.

Data Classification in Product Data Management

Morshedzadeh, Iman January 2013 (has links)
This report is about the product data classification methodology that is useable for the Volvo Cars Engine (VCE) factory's production data, and can be implemented in the Teamcenter software. There are many data generated during the life cycle of each product, and companies try to manage these data with some product data management software. Data classification is a part of data management for most effective and efficient use of data. With surveys that were done in this project, items affecting the data classification have been found. Data, attributes, classification method, Volvo Cars Engine factory and Teamcenter as the product data management software, are items that are affected data classification. In this report, all of these items will be explained separately. With the knowledge obtained about the above items, in the Volvo Cars Engine factory, the suitable hierarchical classification method is described. After defining the classification method, this method has been implemented in the software at the last part of the report to show that this method is executable.

Extending the Metaphor : Technical Debt in General Product Development

Hansson, Malin, Hognesius, Maria January 2015 (has links)
It is arguably an important matter to track and eliminate poor quality. One way of doing this within software development is by applying the technical debt metaphor and using it as a basis when estimating the quality level. There was interest expressed in investigating whether this metaphor could be extended to the development of non-software products and use it as a starting point for developing features in a PLM (product lifecycle management) system able to track and help monitor technical debt throughout the lifecycle of a product. Thus, a case study based on a literature review and interviews analysed qualitatively were conducted. The result consists of the knowledge that similar notions as found in the technical debt research could successfully be applied to other development processes and phenomena as well, a framework consisting of types of technical debt and a “sketch” for how to measure it, and that in a technical debt-tracking feature it could be beneficial with functionality for implementing models for debt quantification, for allowing the organisation to set up rules, and for crawling through the product taxonomy in the PLM system, detecting deviances from aforementioned rules.

Design for Sustainability through a Life Cycle Assessment Conceptual Framework Integrated within Product Lifecycle Management

Zou, Renpeng 04 April 2018 (has links)
The need to include sustainable design principles during product realization poses several challenges in need of research. The demand for greener products has increased while competition has shortened product realization processes. Product Lifecycle Management (PLM) provides solutions in accelerating the development process and time to market by managing the information through a full life cycle of a product line. Life Cycle Assessment (LCA) provides a way to predict the environmental impacts that should be expected over the complete life cycle of a given product, but LCA methods are not well suited to efficient comparison of product alternatives during early design stages. Customers and other stakeholders demand products that not only comply with regulations and minimize environmental impacts, but also minimize costs and maximize certain performance objectives of a product. Thus, an approach is needed to unify validation of new products compliance with holistic consideration of environmental impacts along with other objectives over a complete life cycle for the selection of the optimal design concept in an efficient manner. This research addresses these matters by proposing the approach of integrating LCA software with a PLM system. A conceptual LCA framework- LCAatPLM (Life Cycle Assessment of assembly tree in PLM) is proposed that allows environmental assessment of assembly tree directly extracted from PLM. Firstly, relevant existing solutions are reviewed and several challenges are identified that prevent integration. By decomposing the structure of both PLM and LCA, a common foundation is identified for the integration. Then, a design methodology is developed to show the use of LCAatPLM within PLM environment. A charcoal grill design case study is detailed to show how evaluations can be made based on achievement of strategic goals, along with verification of compliance and the visibility of LCA and other results. Our findings show that design executions through LCA integrated with PLM reveal environmental criterion at early stages. It can be considered with other design criteria to identify and select optimal alternatives. This research transforms LCA as an evaluation tool used after a design is already completed to one that can guide designs earlier within the PLM environment.

Support component reusability by integrating augmented reality and product lifecycle management

Quesada Díaz, Raquel January 2016 (has links)
In an ever changing market that expands continuously and where innovations cycles become shorter, there is an important increase of the renewal frequency of the electrical and electronic equipment (EEE) and vehicles. This makes the manufacture of EEE and vehicles a fast-growing source of waste in terms of used products. The immense amount of information generated by all these technological products which are currently in the market must be managed throughout the whole life cycle of the products. The problem is to provide information about the technological product’s reusability in the recycling process given the colossal complexity of many products and the lifespan of operation. This includes instructions about the components qualifications as elements in a new product. Technologies such as augmented reality (AR) combined with product lifecycle management (PLM) systems can provide the platform for an information system that provides the necessary information and support for the decommissioning process of EEE and vehicles at the end of their life cycle. The present project describes the framework of integration between AR and PLM with the purpose of recycling a technological product at the end of its life cycle. The proposed method of integration could be considered to constitute both an innovation and a possible improvement if compared with the current approach. It is believed that the development of a method that addresses the issue of integration between AR and PLM could provide with a secure, efficient management of stored data related to various products and their properties related to the recycling process at the end-of-life of the product. The result of this approach is an AR-PLM system architecture which assists the circular economy’s recycling process by the use of visual information superimposed on the physical technological equipment.

Einheitliches Konzept einer Kommunikationsschnittstelle zur systematischen Integration von Maschinendaten in den Prozessbereich von Product Lifecycle Management

Arndt, Stephan Günter 11 April 2022 (has links)
Die Prozesse aus der Betriebsphase von Maschinen beruhen vermehrt auf Daten, die durch fortschrittliche Technologien zur Datenerfassung, -verarbeitung und -kommunikation bereitgestellt werden. Die damit einhergehende, stetig anwachsende Menge maschinenrelevanter Daten bietet aus Sicht von Maschinenherstellern ein großes Optimierungspotenzial für sowohl aktuelle als auch zukünftige Maschinengenerationen und deren betriebsbegleitende Services. Vor diesem Hintergrund und entgegen vorrangig organisatorischer Informationsbarrieren auf Maschinenhersteller- und -betreiberseite ist es notwendig, die speziell für die Produktentstehung und bspw. die Instandhaltung relevanten Maschinendaten in den Prozessbereich von PLM systematisch zu integrieren. Zu diesem Zweck wird in dieser Dissertation das Feldkonzept als grundlegende Beschreibung einer Kommunikationsschnittstelle zur einheitlichen Integration von Maschinendaten vorgestellt. Die Datenintegration erfolgt virtuell und prozessunterstützt-reproduzierbar auf der Applikationsebene einer Feldmanagementplattform als Middleware sowie anhand einer Feldstruktur als Mapping-Grundlage. Die Feldstruktur dient der konsistenten Verknüpfung ausgewählter Produktstrukturinformationen mit Strukturinformationen von Maschinen aus deren Betriebsphase. Das als Feldmodell bezeichnete Integrationsergebnis dient als Vehikel zum Austausch ausgewählter und logisch in einem Datensatz gemeinsam strukturierter Produkt- und/oder Maschinendaten zu bspw. Analysezwecken. Mithilfe des Feldmodells lassen sich Maschinendaten dokumentbasiert im Produktdatenmanagement zu speichern.:1 Einleitung 2 Grundlagen 3 Arbeitsbereich 4 Das Feldkonzept 5 Grundprinzipien des Feldmanagementsystems 6 Validierung des Feldkonzepts 7 Zusammenfassung und Ausblick

Implementation of re-usable, configurable systems engineering model using product lifecycle management platform

Zhang, Weijie 08 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Industry is facing the challenge of increasing product complexity while at the same time reducing cost and time in a highly competitive global market. Product Lifecycle Management (PLM) and Systems Engineering have the potential to help companies avoid costly product development and launching, as well as failure during use; these two concepts not only share many common characteristics, but also complement each other. PLM provides an information management system that can seamlessly integrate enterprise data, business processes, business systems and, ultimately, people throughout all phases of the product lifecycle. Systems engineering is an interdisciplinary approach to designing, implementing, evaluating, and managing the complex human-made systems over their life cycle. The same underlying methods that improve management of products and services can be used to organize the framework in which PLM systems are implemented, integrated, and evolved. Though several studies have indicated that adopting Systems Engineering with PLM brings many benefits for industries, implementation of PLM based Systems Engineering with PLM has rarely been conducted. Pattern-Based Systems Engineering (PBSE), a form of Model-Based Systems Engineering (MBSE) based on the use of Systematic Metamodel (S* Metamodel), represents a family of manufacturing system, and is used in the life cycle processes of ISO 15288, was implemented here using TEAMCENTER® PLM software as the platform. More specifically, we have implemented the key portion of the General Production Pattern based on S* Metamodel, and demonstrated the benefit through the manufacturing of oil filter case study. The above implementation have resulted in a powerful systems engineering model in PLM that leverages the capabilities of Teamcenter, to enable an enhanced systems engineering approach. Benefits brought to systems engineering practice include: the ability to capture and reflect stakeholders' requirements and changes in product design process promptly and accurately; the ability of systems engineers to create models quickly and prevent mistakes during modeling; the ability of systems engineers to do their job much easily by using reusable and reconfigurable models; the ability to re-use of previous designs in a new process.

The Storage of Parametric Data in Product Lifecycle Management Systems

Lund, Jonathan Gary 23 March 2006 (has links) (PDF)
Product development companies are continually seeking methods to increase efficiency while maintaining quality. Distributed development is also more important than ever before as industries globalize. These forces have driven firms to adopt formal data management practices that allow groups and individuals to work from singular, centralized data source that are secure, reliable, and support collaboration. This thesis proposes a methodology to leverage globalized infrastructures for the efficient storage of product variations. The methodology is proved through a working prototype using the market leader in Product Lifecycle Management (PLM) systems, Teamcenter Engineering. First, paradigms are set forth for the storage of various types of engineering documents in PLM systems in parametric formats. Then the use of these paradigms is exemplified by various programs retrieving and storing document variations in the form of PLM metadata. Finally, the results show that this methodology produces drastic increases in system performance as well as the enabling of PLM-compatible automation and optimization. The impacts of these findings have significant implications for industry and has generated interest from several global engineering firms and academic journals.
