The PSS : From Flat Maps to Layered Perspectives - the contribution of the Airport Metropolis Planning Support System (PSS) to sub-regional planning in the Brisbane Airport case environment
No full textConventional planning and decision making, with its sectoral and territorial emphasis and flat-map based processes are no longer adequate or appropriate for the increased complexity confronting airport/city interfaces. These crowed and often contested governance spaces demand a more iterative and relational planning and decision-making approach. Emergent GIS based planning and decision-making tools provide a mechanism which integrate and visually display an array of complex data, frameworks and scenarios/expectations, often in ‘real time’ computations. In so doing, these mechanisms provide a common ground for decision making and facilitate a more ‘joined-up’ approach to airport/city planning. This paper analyses the contribution of the Airport Metropolis Planning Support System (PSS) to sub-regional planning in the Brisbane Airport case environment
Developing tools to support complex infrastructure decision-making
No full textThe rapidly changing role of capital city airports has placed demands on surrounding infrastructure. The need for infrastructure management and coordination is increasing as airports and cities grow and share common infrastructure frameworks. The purpose of this paper is to document the changing context in Australia, where the privatisation of airports has stimulated considerable land development with resulting pressures on surrounding infrastructure provision. It aims to describe a tool that is being developed to support decision-making between various stakeholders in the airport region. The use of planning support systems improves both communication and data transfer between stakeholders and provides a foundation for complex decisions on infrastructure. The research uses a case study approach and focuses on Brisbane International Airport and Brisbane City Council. The research is primarily descriptive and provides an empirical assessment of the challenges of developing and implementing planning support systems as a tool for governance and decision-making. The research assesses the challenges in implementing a common data platform for stakeholders. Agency data platforms and models, traditional roles in infrastructure planning, and integrating similar data platforms all provide barriers to sharing a common language. The use of a decision support system has to be shared by all stakeholders with a common platform that can be versatile enough to support scenarios and changing conditions. The use of iPads® for scenario modelling provides stakeholders the opportunity to interact, compare scenarios and views, and react with the modellers to explore other options. The research confirms that planning support systems have to be accessible and interactive by their users. The Airport City concept is a new and evolving focus for airport development and will place continuing pressure on infrastructure servicing. A coordinated and efficient approach to infrastructure decision-making is critical, and an interactive planning support system that can model infrastructure scenarios provides a sound tool for governance
Modelling contractor's and subcontractor's trust : a system dynamics approach
No full textA general mistrust within the contactor and subcontractor companies has identified one of the\ud
significant barriers to derive benefits from true downstream supply chain integration. Using\ud
the general theory of trust in inter-organizational relations and conducting interviews, this\ud
research discusses factors that influence development of trust and cooperation in contractor–\ud
subcontractor relationships in construction projects. System dynamics is the simulation\ud
method is selected in this theory-building effort, based on qualitative data collected from two\ud
projects of a construction company in Thailand. Performance, permeability and system based\ud
trust are found to make significant contributions toward parties’ trust level. Three\ud
strategic policies such as best value contracting, management of subcontractors as internal\ud
team and semi project partnering approach are recommended to stimulate the trust factors as\ud

Development of a performance model for international construction joint venture : a system dynamics approach
No full textThe uncertain and dynamic nature of International Construction Joint Venture (ICJV) performance is evolved with many critical factors which lead to make partner relationships more complex in respect of making decisions to maintain a cohesive environment. Addressing to the fact, a generic system dynamics performance model for ICJV is developed by integrating a number variables as to get an overall impact on performance of ICJV and to make effective decisions based on that. In order to formulate and validate the model both structurally and behaviourally, both qualitative and quantitative data are gathered by conducting intensive interviews from two ICJVs in Thailand. After conducting intensive simulations of model, three major problems are identified related to negative value gap, low productivity in construction and high rate of ineffective information sharing of both ICJVs. Several policies are suggested and integrated application of these policies provides a maximum improvement to performance of the ICJV
Towards an integrated maturity model of asset management capabilities
No full textAsset service organisations often recognize asset management as a core competence to deliver benefits to their business. But how do organizations know whether their asset management processes are adequate? Asset management maturity models, which combine best practices and competencies, provide a useful approach to test the capacity of organisations to manage their assets. Asset management frameworks are required to meet the dynamic challenges of managing assets in contemporary society. Although existing models are subject to wide variations in their implementation and sophistication, they also display a distinct weakness in that they tend to focus primarily on the operational and technical level and neglect the levels of strategy, policy and governance as well as the social and human resources – the people elements. Moreover, asset management maturity models have to respond to the external environmental factors, including such as climate change and sustainability, stakeholders and community demand management. Drawing on five dimensions of effective asset management – spatial, temporal, organisational, statistical, and evaluation – as identified by Amadi Echendu et al. [1], this paper carries out a comprehensive comparative analysis of six existing maturity models to identify the gaps in key process areas. Results suggest incorporating these into an integrated approach to assess the maturity of asset-intensive organizations. It is contended that the adoption of an integrated asset management maturity model will enhance effective and efficient delivery of services
Managing knowledge for asset management : shifting from process to relational frames
No full textThe purpose of this paper is to review existing knowledge management (KM) practices within the field of asset management, identify gaps, and propose a new approach to managing knowledge for asset management. Existing approaches to KM in the field of asset management are incomplete with the focus primarily on the application of data and information systems, for example the use of an asset register. It is contended these approaches provide access to explicit knowledge and overlook the importance of tacit knowledge acquisition, sharing, and application. In doing so, current KM approaches within asset management tend to neglect the significance of relational factors; whereas studies in the KM field have showed that relational modes such as social capital is imperative for effective KM outcomes. In this paper, we argue that incorporating a relational approach to KM is more likely to contribute to the exchange of ideas and the development of creative responses necessary to improve decision making in asset management. This conceptual paper uses extant literature to explain KM antecedents and explore its outcomes in the context of asset management. KM is a component in the new integrated strategic asset management (ISAM) framework developed in conjunction with asset management industry associations (AAMCoG 2012) that improves asset management performance. In this paper, we use Nahapiet and Ghoshal’s [24] model to explain antecedents of relational approach to KM. Further, we develop an argument that relational KM is likely to contribute to the improvement of the ISAM framework components, such as organizational strategic management, service planning, and delivery. The main contribution of the paper is a novel and robust approach to managing knowledge that leads to the improvement of asset management outcomes
A Bibliometric Analysis of Ageing Literature: Global and Asia-Pacific Trends

Given that the Asia Pacific region has been ageing more rapidly than at any time in history, this chapter examines the body of literature on "ageing" by mapping the prevalent themes of research, research hotspots, and influential stake-holders. The findings have implications for researchers into ageing as well as policymakers across countries included in this volume and beyond
Asset management policies and guidelines of different states in Australia: a comparative analysis
No full textPurpose – The purpose of this paper is to explore and compare the asset management policies and practices of six Australian states – New South Wales, Victoria, Queensland, South Australia, Western Australia and Tasmania – to improve understanding of the policy context to best shape policy focus and guidelines. Australian state-wide asset management policies and guidelines are an emergent policy domain, generating a substantial body of knowledge. However, these documents are spread across the layers of government and are therefore largely fragmented and lack coherency. Design/methodology/approach – The comparative study is based on the thematic mapping technique using the Leximancer software. Findings – Asset management policies and guidelines of New South Wales and Victoria have more interconnected themes as compared to other states in Australia. Moreover, based on the findings, New South Wales has covered most of the key concepts in relation to asset management; the remaining five states are yet to develop a comprehensive and integrated approach to asset management policies and guidelines. Research limitations/implications – This review and its findings have provided a number of directions on which government policies can now be better constructed and assessed. In doing so, the paper contributes to a coherent way forward to satisfy national emergent and ongoing asset management challenges. This paper outlines a rigorous analytical methodology to inform specific policy changes. Originality/value – This paper provides a basis for further research focused on analyzing the context and processes of asset management guidelines and policies
A Bibliometric Analysis of Literature on Labour and Skill Shortages: Implications for the Future of Work in the Asia-Pacifc and Beyond
No full textThe rapidly evolving diffusion of digital technologies, the transition to a climate-neutral economy, and the changing nature of the future of work have been considered the dominant phenomena of this millennium, resulting in labour and skill shortages across developed and developing economies worldwide. Although the Asia-Pacific region has a workforce of over 2 billion, it is estimated to face critical labour and skill shortages of nearly 50 million by 2030. The size of the workforce and the associated shortages have implications for the United Nations’ 2030 Agenda and its 17 Sustainable Development Goals (SDGs). This chapter conducts a bibliometric analysis to examine the literature on ‘labour and skills shortages’. It maps the most and least prominent research themes, research outlets, and influential researchers. The findings have implications for scholars, industry professionals, and policymakers
Quantifying the cost of quality in construction projects: an insight into the base of the iceberg
No full textConstruction projects are complex endeavors where achieving higher quality standards is challenging due to the intrinsic difficulties and dynamic quality management processes. Several quality management techniques exist to overcome quality concerns, such as the cost of quality (COQ). However, implementing COQ in building construction is challenging due to the absence of a comprehensive quality cost-capturing system. Several studies have tried to quantify different quality costs but are mainly focused on visible failure cost—the tip of the iceberg while the base of the iceberg has rarely been explored. This study develops and quantifies each component of the visible and hidden quality costs—the base of the iceberg. Accordingly, a modified prevention, appraisal, and failure model is developed and applied to the primary data of 25 building projects. The findings highlight the unfamiliarity and passive attitude of the involved construction firms towards quality, thus, incurring higher failure costs amounting to over 12% of the total project cost. Most of this cost remains hidden as traditional accounting systems cannot capture it. Such costs must be eliminated by implementing COQ systems as utilized in the current study. Further, a quality costing framework is established for building projects and applied to the local construction industry to reduce construction failures and improve the quality performance of building projects
