    Intelligent Products: Shifting the Production Control Logic in Construction (With Lean and BIM)

    Production management and control in construction has not been addressed/updated ever since the introduction of Critical Path Method and the Last PlannerÂź system. The predominant outside-in control logic and a fragmented and deep supply chain in construction significantly affect the efficiency over a lifecycle. In a construction project, a large number of organisations interact with the product throughout the process, requiring a significant amount of information handling and synchronisation between these organisations. However, due to the deep supply chains and problems with lack of information integration, the information flow down across the lifecycle poses a significant challenge. This research proposes a product centric system, where the control logic of the production process is embedded within the individual components from the design phase. The solution is enabled by a number of technologies and tools such as Building Information Modelling, Internet of Things, Messaging Systems and within the conceptual process framework of Lean Construction. The vision encompasses the lifecycle of projects from design to construction and maintenance, where the products can interact with the environment and its actors through various stages supporting a variety of actions. The vision and the tools and technologies required to support it are described in this pape

    Eco Global Evaluation: Cross Benefits of Economic and Ecological Evaluation

    This paper highlights the complementarities of cost and environmental evaluation in a sustainable approach. Starting with the needs and limits for whole product lifecycle evaluation, this paper begins with the modeling, data capture and performance indicator aspects. In a second step, the information issue, regarding the whole lifecycle of the product is addressed. In order to go further than the economical evaluations/assessment, the value concept (for a product or a service) is discussed. Value could combine functional requirements, cost objectives and environmental impact. Finally, knowledge issues which address the complexity of integrating multi-disciplinary expertise to the whole lifecycle of a product are discussing.EcoSD NetworkEcoSD networ

    Integrated product relationships management : a model to enable concurrent product design and assembly sequence planning

    Get PDF
    The paper describes a novel approach to product relationships management in the context of concurrent engineering and product lifecycle management (PLM). Current industrial practices in product data management and manufacturing process management systems require better efficiency, flexibility, and sensitivity in managing product information at various levels of abstraction throughout its lifecycle. The aim of the proposed work is to manage vital yet complex and inherent product relationship information to enable concurrent product design and assembly sequence planning. Indeed, the definition of the product with its assembly sequence requires the management and the understanding of the numerous product relationships, ensuring consistency between the product and its components. This main objective stresses the relational design paradigm by focusing on product relationships along its lifecycle. This paper gives the detailed description of the background and models which highlight the need for a more efficient PLM approach. The proposed theoretical approach is then described in detail. A separate paper will focus on the implementation of the proposed approach in a PLM-based application, and an in-depth case study to evaluate the implementation of the novel approach will also be given

    Framework for Product Lifecycle Management integration in Small and Medium Enterprises networks

    Get PDF
    In order to improve the performance of extended enterprises, Small and Medium Enterprises (SMEs) must be integrated into the extended networks. This integration must be carried out on several levels which are mastered by the Product Lifecycle Management (PLM). But, PLM is underdeveloped in SMEs mainly because of the difficulties in implementing information systems. This paper aims to propose a modeling framework to facilitate the implementation of PLM systems in SMEs. Our approach proposes a generic model for the creation of processes and data models. These models are explained, based on the scope and framework of the modeling, in order to highlight the improvements provided

    Can procurement affect design performance?

    Get PDF
    There is an emerging view in the construction industry that better performance or better value for money can be achieved by integrating teamwork for planning, design and construction of building projects. There are though, two opposing perspectives regarding how changes in traditional design practices should occur. Advocates of sustainable construction in North America posit that it is a matter of evolving processes, moving from a sequential to an iterative approach to design, whereas the British government supports the view that a change in how projects are procured is required to transform the context that dictates relationships among the members of the team. The objective of the research is to study the influence of procurement on the performance of integrated design teams. It analyses, through case studies representing these two perspectives, the influence of procurement on the performance of integrated teams. The research is conclusive in that it is the context created by contractual relationship, and not the process set up for conducting integrated design, that most influence team efficiency. It demonstrates that traditional procurement processes reinforce socio-cognitive barriers that hinder team efficiency. It also illustrates how new procurement modes can transform the dynamics of relationships between the client and the members of the supply chain, and have a positive impact on team performance
