Interactive Visualization for Information Flow in Production Chains: Case Study Industrialised House-Building

Abstract

Predefinitions in house-building platforms is developed as routines to manage project building information models over to production data by documents and digital drawings. Visualisation of the information flow in the industrialised house-building process is hard to track and information are often presented as islands, seldom described in the flow for the entire process. Interactive visualisation, using game technology, has open up for new applications of data-transformation,-visualization and-simulation of project information which is less studied in the context of industrialised house-building. This paper tries to address this issue via a combination of game engine technology and the predefined industrialised house-building process. The game engine technology allow development for end-user demands and functionality to express and visualise values for the daily planning and execution of processes. In a case study approach the development and analysis of four building projects were studied and chosen to the range of product platform predefinitions. Based on object structure for different views, models and the related metadata were visualised with an immersive virtual environment prototype. The prototype, based on game engine technology, was developed to manage incoming building projects variations that followed house-building platform predefinitions. As a visualising tool of engineering, on-site planning and production process the game engine technology simulates and visualize views on product structures, production information, assembling and operation instructions by interactive functions in the game environment.

“…Standard predefined parts of the product, such as modular components and elements, are based on building systems, which is the underlying core product technology. The predefined parts form commonality across a product range, and their configuration generates product variants that are differentiated by the market (Jansson, 2013;Popovic, 2020). Predefined parts and building systems are solutions that are developed considering the whole lifecycle of products (Persson et al, 2009).…”
