Implementation of Hybrid Simulation Modelling Framework in Construction

Abstract: The goal of construction system modelling is to improve construction work performance by tracking the dynamic behaviour of construction systems. Discrete-Event Simulation (DES) has been suggested as a supporting tool for management decision-making in order to capture the dynamic complexity of construction projects. However, the limitations of DES in modelling influential factors such as the individual and emergent behaviour of system entities have led to the combined use of Agent-based Simulation (ABS) and DES. This paper provides an overview of DES and ABS applications in construction, and then discusses rationale for integrating DES and ABS from the conceptual stage onwards. Furthermore, a hybrid DES-ABS conceptual framework is introduced and the challenges of this type of hybrid simulation model are explained.

DEVELOPING WITHIN-COMPANY INFORMATION AND COMMUNICATION TECHNOLOGIES (ICT) INNOVATION DIFFUSION NETWORKS: A STUDY OF THREE AUSTRALIAN MAJOR CONTRACTORS

Abstract: The innovation diffusion and knowledge management literature strongly supports the importance of communities of practice (COP) for enabling knowledge about how to use and adopt innovation initiatives. One of the most powerful tools for innovation diffusion is word-of-mouth wisdom from committed individuals who mentor and support each other. Close proximity for face-to-face interaction is highly effective, however, many organisations are geographically dispersed with projects being virtual linked sub-organisations using ICT to communicate. ICT has also introduced a useful facilitating technology for developing knowledge networks. This paper presents findings from a research program concentrating on ICT innovation diffusion in the Australian construction industry. One way in which ICT diffusion is taking place was found to be through within-company communities of practice. We undertook in-depth unstructured interviews with three of the major 10 to 15 contractors in Australia to discuss their ICT diffusion strategies. We discovered that in all three cases, within-company networked communities of practice was a central strategy. Further, effective diffusion of ICT groupware tools can be critical in developing COP where they are geographically dispersed.

Information technology foresight:the future application of theworld wide web in construction

Abstract: Information technology (IT) is fundamentally changing global construction business. TheInternet, and more specifically the World Wide Web (WWW) will be key to this change.Forecasting technological change is notoriously difficult. This is becoming furtherexacerbated by the increasingly evident cycles of over-hype and disillusionment that newtechnologies and management paradigms face.Science policy research has developed innovative forecasting methods to deal with such aproblem. Key within these is the use of scenarios to describe the integrative effects ofdevelopments in parallel technologies and their socio-economic context.This paper contains a detailed scenario of the way the WWW may be used in globalconstruction in the year 2001. Analysis of the scenario causes key questions to be askedregarding the impact of technology development in construction. These questions are inneed of urgent, serious consideration by: governments, senior construction executives,educators, students, researchers, recruiters, and new entrants to the industry.The answers to these questions will help shape a key component of the research andinnovation agenda for construction for what is left of this millennium.
