On the Development of a Reference Framework for ICT for Manufacturing Skills
No full textPart IV: ICT and Emerging TechnologiesInternational audienceIn this paper, we plead for the development of a reference framework for ICT for manufacturing skills. The existing e-skills frameworks are either too general or too restrictive. That is why there is a need for a reference framework for ICT skills in manufacturing to be used as a common reference by all Industrial Learning stakeholders when dealing with issues related to ICT skills in manufacturing. The framework should be capable to capture most of state-of-the-art e-skills relevant to manufacturing in addition to the skills related to emerging ICT for manufacturing. Such a framework would encourage manufacturing workers to take training on specific ICT skills. The motivation for pleading for a reference framework for ICT for manufacturing skills and the requirements related to its development are presented in this paper
Identification of the Inspection Specifications for Achieving Zero Defect Manufacturing
No full textPart 4: Product and Asset Life Cycle Management in Smart Factories of Industry 4.0International audienceThe contemporary manufacturing landscape is characterized by increased volatility shortened product life cycles and increased degree of product customization. Manufacturing companies are continuously facing the challenge of operating their manufacturing processes and systems in order to deliver the required production rates of high quality products, while minimizing the use of resources. They can achieve this with a concept named Zero Defect Manufacturing. This concept implies that inspection is performed to all the parts and therefore they can achieve zero defects. The problem is that inspection can be either time consuming process or a very expensive process. The goal of the current research work is a methodology for the identification of the acceptable inspection specification in order for the production system to stay efficient and at the same time produce non-defected products. In other words the outcome of this paper will be a set of maps that depicts which can be the acceptable inspection characteristics such as inspection time and inspection cost
A Concept for Graph-Based LCA Analysis Tool
No full textPart IV: ICT and Emerging TechnologiesInternational audienceLife Cycle Assessment is a comprehensive life cycle approach that quantifies ecological and human health impacts of a product or system over its complete life cycle [5]. The existing LCA and environmental assessment tools do not model the relations between different lifecycle factors or different environmental dimensions and focus mostly on the inventory analysis. The main idea of the proposed concept is to develop environmental assessment tools in order to evaluate the environmental performance and deliver a dynamic environmental profile for products, services and processes, by taking into account the various dimensions of environmental impact, as well as the relations between different factors in their lifecycle. Furthermore, this concept proposes a graph-based representation of different lifecycle factors and dimensions in order to facilitate the visual analysis and simulation of the product/service/process lifecycle. Finally, this concept provides a way to model environmental KPIs as a representation to different lifecycle factors and a simulation environment
Semantic Data Model for Operation and Maintenance of the Engineering Asset
No full textPart IV: ICT and Emerging Technologies in Production ManagementInternational audienceThe management of engineering assets within an organization is a challenging task that aims to optimize their performance through efficient decision making. However, the current asset data management systems suffer from poor system interoperability, data integration issues as well as an enormous amount of stored data, thus preventing a seamless flow of information. The aim of this work is to propose a semantic data model for engineering asset management, focusing on the operation and maintenance phase of its life cycle. Ontologies are proposed because they can capture the semantics of data, create a shared vocabulary to describe the knowledge for sharing in the domain and provide reasoning capabilities. This model will gather all the knowledge necessary to assist in the decision making process in order to improve the asset’s availability, longevity and quality of operations
Linked Data Exploration in Product Life-Cycle Management
No full textPart IV: ICT and Emerging TechnologiesInternational audienceProduct Life Cycle Management (PLM) strategies have been proven as recommended approach for handling, planning and decision making regarding all aspects of products different life cycle stages. As this domain includes number of actors, system platforms and technologies, gathering information and handling knowledge often emerges as challenging problem. In this paper we propose a methodology to support a PLM approach taking advantage from the emerging semantic web technologies and the underlying paradigm of Linked Data. The main purpose of this methodology is twofold. First, it aims at providing a semantic model for handling different data sources and data types, structuring thus information from all stages of a product life cycle. Second, it extends reasoning mechanisms offered by semantic technologies, to conduct comparative and in-depth data analysis based on data mining and pattern discovery
Introducing Engineering Concepts to Secondary Education Through the Application of Pedagogical Scenarios in “Manuskills” Project
No full textPart 4: Project Management, Engineering Management, and Quality ManagementInternational audienceThe current paper identifies the lack of engineering concepts taught in secondary education and to this end proposes a new approach to be followed. The contents of the aforementioned approach are subject to the EU project Manuskills and the research conducted in its concept. The utilization of pedagogical scenarios is proposed as a tool for secondary school teachers towards the incorporation of engineering concepts into their teaching practice. The nature and the characteristics of pedagogical scenarios that constitute them appropriate for this purpose will be reported and analyzed

high demands to SMEs as well to MNCs. The paper describes an approach on
Eco-factories based on the EU-funded FP7 project EMC2. Eco-factories will
enable the quantum leap in integrating environmental issues in brownfield and
greenfield factory planning and factory operation. The paper focuses on the
identification, structuring and definition of requirements for Eco-factories.
Based on the requirements analysis Best-availabe-technologies from an interna-tional state-of-the-art are identified and pave the way to a holistic vision of Eco-factories
A Study on Social Assessment in Holistic Lifecycle Management
No full textPart 10: Product-Service Lifecycle Management: Knowledge-Driven Innovation and Social ImplicationsInternational audienceSustainable manufacturing has been focus of the industry for some time. Due to the holistic nature of sustainability not only the manufacturing processes but the whole life cycle and the environmental, economic and social aspects of the product should be taken in to account. In order to leverage from the concept of sustainability it is necessary to involve it in decision making process in the supply chain. It is essential to have an evaluation procedure so as to involve it in decision making which should be capable of assessing economic, environmental and social performance of the product. Unfortunately the social dimension of sustainability is the least developed and even neglected because it is difficult to evaluate due to its quantitative and subjective nature. The social aspects of holistic life cycle approach will be presented in this paper
Closed-Loop Life Cycle Management Concept for Lightweight Solutions
No full textPart V: Product and Asset Lifecycle ManagementInternational audienceLightweighting is the point of interest especially for automotive and aerospace industries. Wrought aluminum alloys have great potential in lightweighting. There is a need to increase post-consumer recycling and use of recycled aluminum in high-end structural components to exploit the full potential of wrought aluminum alloys. Closed-loop product life cycle management (PLM) may enable to increase the recycling of wrought aluminum alloys by providing essential information about the individual parts. Considering separate life cycle phases, products and processes may seem environmentally friendly, but it is not possible to be sure unless the entire life cycle is taken into account. LCA and LCC are scientific investigative processes which take into account entire life cycle of the products and help decision makers to evaluate between alternatives in product development
A Scheduling Tool for Achieving Zero Defect Manufacturing (ZDM): A Conceptual Framework
No full textPart 5: Industry 4.0 - Digital TwinInternational audienceContemporary manufacturing landscape has changed and has become highly volatile and demanding. Product Life Cycle has significantly decreased because of the consumers’ need for personalized products in shorter period of time. This need forced the manufacturers to produce smaller batches of highly diversified products instead of producing huge batches of the same product. These newly imposed production requirements made the manufacturers struggle to optimize their productions in such short period of time and therefore, these production requirements created the need for more efficient, productive and eco-friendly planning and scheduling. The solution to this problem can be given partially by a concept named “Zero Defect Manufacturing” (ZDM). The goal of ZDM is to eliminate defected parts and therefore achieving higher efficiency, eco-friendliness and lower production costs. There are four ZDM strategies that are interconnected with each other: detection, repair, prediction and prevention. The current research work focuses on the Beginning of Life of the product and considers the development of a dynamic Scheduling tool combined with an intelligent Decision Support System (DSS) that takes into consideration the ZDM strategies for eliminating defected parts during production. The elimination of defected parts would be done mainly by creating specific algorithms for predicting when a defect may occur and for taking the right decisions in order to prevent the defect occurrence. Finally, an industrial example is presented in order to illustrate the potential benefits of such an approach
