  • the use of Virtual Prototyping for hazard identification in the early design stage
    Construction Innovation: Information Process Management, 2012
    Co-Authors: Chan King Chun, Martin Skitmore
    Abstract:

    Purpose – The construction industry is well known for its high accident rate and many practitioners consider a preventative approach to be the most important means of bringing about improvements. The purpose of this paper is to address previous research and the weaknesses of existing preventative approaches and then to describe and illustrate a new application involving the use of a multi‐dimensional simulation tool – Construction Virtual Prototyping (CVP).Design/methodology/approach – A literature review was conducted to investigate previous studies of hazard identification and safety management and to develop the new approach. Due to weaknesses in current practice, the research study explored the use of computer simulation techniques to create Virtual environments where users can explore and identify construction hazards. Specifically, Virtual Prototyping technology was deployed to develop typical construction scenarios in which unsafe or hazardous incidents occur. In a case study, the users' performanc...

  • life cycle management of construction projects based on Virtual Prototyping technology
    Journal of Management in Engineering, 2010
    Co-Authors: Hongling Guo, Martin Skitmore, Heng Li
    Abstract:

    Life-cycle management (LCM) has been employed in the management of construction projects for many years in order to reduce whole life cost, time, risk and improve the service to owners. However, owing to lack of an effective information sharing platform, the current LCM of construction projects is not effectively used in the construction industry. Based upon the analysis of the information flow of LCM, a Virtual Prototyping (VP)-based communication and collaboration information platform is proposed. Following this, the platform is customized using DASSAULT software. The whole process of implementing the VP-based LCM of projects is analyzed via the application to a real-life construction project. The advantages of implementing a VP-based LCM are also discussed and, from a simple case study, it is demonstrated that the VP-based communication and collaboration information platform is an effective tool to support the LCM of construction projects.

  • using the ikea model and Virtual Prototyping technology to improve construction process management
    Construction Management and Economics, 2008
    Co-Authors: Heng Li, Mirioslaw J Skibniewski, Martin Skitmore
    Abstract:

    Learning from manufacturing industries is a useful approach to improving the productivity of the construction industry and to solve problems arising from construction processes. Through the use of Virtual Prototyping (VP) technology, the lean production process engaged in the IKEA business model (IKEA model) is studied and implemented in a real-life construction project. Specifically, based on the analysis of the IKEA model, the IKEA model can be applied to optimize construction processes and simplify management activities. A case study is analysed to demonstrate the improvement of construction process management through using the VP-IKEA approach.

  • fast Virtual Prototyping of cyber physical systems using systemc and fmi adas use case
    Rapid System Prototyping, 2019
    Co-Authors: Salah Eddine Saidi, Amir Charif, Tanguy Sassolas, Pierreguillaume Le Guay, Henrique Vicente Souza, Nicolas Ventroux
    Abstract:

    The design of Cyber-Physical Systems is becoming challenging due to their growing complexity. Simulation has proven to be effective for design validation of such complex systems at low cost. In particular, Virtual Prototyping allows early validation of hardware/software components. Considering the full cyber-physical context of a system allows more accurate testing and validation. This paper presents a fast Virtual Prototyping method for hardware and software co-validation through co-simulation of the whole Cyber-Physical System. The presented solution is based on FMI, a widely adopted standard for multi-domain co-simulation. The VPSim Virtual Prototyping tool is adapted to comply with the FMI standard. As such, an FMU that encapsulates a Virtual hardware/software platform can be easily and automatically generated using a high-level description of the hardware/software architecture. This FMU can then be incorporated in any FMI-compliant simulation tool. The proposed approach features a parallel implementation of the generated FMU to improve the co-simulation performance. An ADAS use-case is used to validate the proposed solution. Obtained results show that a real-time factor of 0.9 can be achieved using the proposed solution.

  • fast Virtual Prototyping for embedded computing systems design and exploration
    Rapid Simulation and Performance Evaluation: Methods and Tools, 2019
    Co-Authors: Amir Charif, Tanguy Sassolas, Gabriel Busnot, Rania Mameesh, Nicolas Ventroux
    Abstract:

    Virtual Prototyping has been widely adopted as a cost-effective solution for early hardware and software co-validation. However, as systems grow in complexity and scale, both the time required to get to a correct Virtual prototype, and the time required to run real software on it can quickly become unmanageable. This paper introduces a feature-rich integrated Virtual Prototyping solution, designed to meet industrial needs not only in terms of performance, but also in terms of ease, rapidity and automation of modelling and exploration. It introduces novel methods to leverage the QEMU dynamic binary translator and the abstraction levels offered by SystemC/TLM 2.0 to provide the best possible trade-offs between accuracy and performance at all steps of the design. The solution also ships with a dynamic platform composition infrastructure that makes it possible to model and explore a myriad of architectures using a compact high-level description. Results obtained simulating a RISC-V SMP architecture running the PARSEC benchmark suite reveal that simulation speed can range from 30 MIPS in accurate simulation mode to 220 MIPS in fast functional validation mode.

  • Virtual Prototyping of cyber physical systems
    Asia and South Pacific Design Automation Conference, 2012
    Co-Authors: Wolfgang Mueller, Markus Becker, Ahmed Elfeky, Anthony Dipasquale
    Abstract:

    The modeling and analysis of Cyber-Physical Systems (CPS) is one of the key challenges in complex system design as heterogeneous components are combined and their close interaction with the physical environment has to be considered. This article presents a methodology and an open toolset for the Virtual Prototyping of CPS. The focus of the methodology is the Virtual Prototyping of the embedded software combined with the Prototyping of the physical environment in order to capture the complete closed control loop of the software over the hardware via sensors/actors with the physical objects. The methodology is based on the application of integrated open source tools and standard languages, i.e., C/C++, SystemC, and the Open Dynamics Engine, which are combined to a powerful simulation framework. Key activities of the methodology are outlined by the example of an electric two-wheel vehicle.

  • toward low carbon construction processes the visualisation of predicted emission via Virtual Prototyping technology
    Automation in Construction, 2013
    Co-Authors: Johnny Wong, Heng Li, Haoran Wang, Ting Huang, Vera Li
    Abstract:

    Abstract The construction industry has been criticised as one of the major greenhouse gas (GHG) emitters and a relatively unregulated sector in the management of carbon emissions. As the pressure on climate change related risks is mounting, a major cut in carbon emissions from construction operations is becoming a top priority if construction firms are to meet increasingly stringent emission controls. This study describes prototype architecture for implementing a carbon emission prediction and a simulation tool for construction projects using Virtual Prototyping technologies that is little investigated, analysed and modelled in the existing literature. The estimated emissions of the construction operations for each activity are calculated, tabulated and plotted to visually demonstrate the emission rates side by side with the integrated 4D models of the construction project. The presented Virtual prototype (VP)-based model allows project teams to visualise the predicted emissions at different times in the construction processes, analyse the emission peaks, and allow the project team to take proactive measures against potential emissions. A real-life public housing construction project in Hong Kong is adopted to demonstrate the application of the emission prediction visualisation tool. By simulating likely carbon emissions during project planning phases in advance of actual construction activities, it is hoped that the tool can encourage exploration of possible strategies to minimize carbon emissions in construction sector.
