Abstract

Purpose ‐ Owing to the numerous part models and massive datasets used in automobile assembly design, virtual assembly software cannot simulate a whole vehicle smoothly in real time. For this reason, implementing a new virtual assembly environment for massive complex datasets would be a significant achievement. The paper aims to focus on this problem. Design/methodology/approach ‐ A new system named "Grid-enabled collaborative virtual assembly environment" (GCVAE) is proposed in the paper, and it comprises three parts: a private grid-based support platform running on an inner network of enterprise; a service-based parallel rendering framework with a sort-last structure; and a multi-user collaborative virtual assembly environment. These components would aggregate the idle resources in an enterprise to support assembly simulation with a large complex scene of whole vehicle. Findings ‐ The system prototype proposed in the paper has been implemented. The following simulations show that it can support a complex scene in a real-time mode by using existing hardware and software, and can promote the efficient usage of enterprise resources. Practical implications ‐ Using the GCVAE, it is possible to aggregate the idle resources in an enterprise to run assembly simulations of a whole automobile with massively complex scenes, thus observably reducing fault occurrence rates in future manufacturing. Originality/value ‐ The paper introduces a new grid-enabled methodology into research on collaborative virtual assembly system which can make the best use of idle resources in the enterprise to support assembly simulations with massively complex product models. A video-stream-based method was used to implement the system; this enables designers to participate ubiquitously in the simulation to evaluate the assembly of the whole automobile without hardware limitations.
