Decision support system for improving construction companies’ business performance

As part of a decision making process, the controlling process in construction companies can be supported by computer application that provides faster and reliable decision. This paper discusses the development of a knowledge-based decision support system for controlling construction companies’ business performance. The knowledge-base was developed using questionnaire survey and case studies. A questionnaire survey was conducted to identify potential problems that can occur in construction companies as well as the source of the problems and their impact on companies’ performance. Case studies were used to identify and analyse various corrective actions. The result of the study shows that decision support system using knowledge-based management system improves the effectiveness and the efficiency of decision making process for selecting the most appropriate corrective action that can improve construction companies’ performance. The application, which had been developed in this research, was designed to support the process of controlling construction companies’ business performance and to assist young manager in selecting the most optimum corrective actions for the problems related to achieving companies’ objectives. This computer application can be used as a learning tool for identifying potential problems that a construction company faces and the most optimum corrective action.

Decision support system architecture for consultant selection

Decision Support System (DSS) has played a significant role in construction project management. This has been proven that a lot of DSS systems have been implemented throughout the whole construction project life cycle. However, most research only concentrated in model development and left few fundamental aspects in Information System development. As a result, the output of researches are complicated to be adopted by lay person particularly those whom come from a non-technical background. Hence, a DSS should hide the abstraction and complexity of DSS models by providing a more useful system which incorporated user oriented system. To demonstrate a desirable architecture of DSS particularly in public sector planning, we aim to propose a generic DSS framework for consultant selection. It will focus on the engagement of engineering consultant for irrigation and drainage infrastructure. The DSS framework comprise from operational decision to strategic decision level. The expected result of the research will provide a robust framework of DSS for consultant selection. In addition, the paper also discussed other issues that related to the existing DSS framework by integrating enabling technologies from computing. This paper is based on the preliminary case study conducted via literature review and archival documents at Department of Irrigation and Drainage (DID) Malaysia. The paper will directly affect to the enhancement of consultant pre-qualification assessment and selection tools. By the introduction of DSS in this area, the selection process will be more efficient in time, intuitively aided qualitative judgment, and transparent decision through aggregation of decision among stakeholders.

A comparative study of manufacturing practices and performance variables

The reported study was conducted to compare and contrast current manufacturing practices between two countries, Australia and Malaysia, and identify the practices that significantly influence their manufacturing performances. The results are based on data collected from surveys using a standard questionnaire in both countries. Evidence indicates that product quality and reliability is the main competitive factor for manufacturers. Maintaining a supplier rating system and regularly updating it with field failure and warranty data and making use of product data management are found to be effective manufacturing practices. In terms of the investigated manufacturing performance, Australian manufacturers are marginally ahead of their Malaysian counterparts. However, Malaysian manufacturers came out ahead on most dimensions of advanced quality and manufacturing practices, particularly in the adoption of product data management, effective supply chains and relationships with suppliers and customers.

Measuring safety effectiveness : literature review

Cohen (1977) reviewed the then current research on occupational safety and stated that both strong company commitment to safety, and communication between all levels of a company are the most influential factors to improving safety. Other relevant factors included careful selection of staff, and early and continuous training throughout the lifetime with the company. These continue to be important factors in OHS today. There has been a continued decrease in the injury rates since Cohen’s review within the Australian construction industry, however, the construction industry has far more injuries and ill-health than the Australian average, with one fatality occurring on average per week in the Australian Construction Industry. The Fatality rate in the building and construction industry remains three times higher than the national average, and 15% of all industry fatalities are in the building and construction industry. In addition the construction industry pays one of the highest workers’ compensation premium rates – in 2001 alone approximately 0.5% ($267 million) of revenue would have to be allocated to the direct cost of 1998/99 compensations (Office of the Federal Safety Commissioner, 2006). Based on these statistics there is a need to measure and improve safety performance within the construction industry.

Teamwork resources to support students and teachers at QUT

The educational advantage of students working cooperatively in teams has been acknowledged in the higher education sector as being profitable in the world of work and other post-university experiences.

Operationalising first year curriculum principles

This project builds on the First Year Curriculum Project that was carried out at the Queensland University of Technology (QUT) in 2006-2007 (QUT, 2007). One of the objectives of that project was “to develop principles for the Course Development processes that capture good design in first year curriculum practice” (p. 1) and this was achieved through the development of a set of broad organising principles for first year curriculum design—the First Year Curriculum Principles (FYCPs) (Kift, 2008).

The evolution of a community of practice at the Queensland University of Technology for lecturers involved in large first year units

Communities of practice (CoPs) may be defined as groups of people who are mutually bound by what they do together (Wenger, 1998, p. 2), that is, they “form to share what they know, to learn from one another regarding some aspects of their work and to provide a social context for that work” (Nickols, 2000, para. 1). They are “emergent” in that the shape and membership emerges in the process of activity (Lees, 2005, p. 7). People in CoPs share their knowledge and experiences freely with the purpose of finding inventive ways to approach new problems (Wenger & Snyder, 2000, p. 2). They can be seen as “shared histories of learning” (Wenger, 1998, p. 86). For some time, QUT staff have been involved in a number of initiatives aimed at sharing ideas and resources for teaching first year students such as the Coordinators of Large First Year Units Working Party. To harness these initiatives and maximise their influence, the leaders of the Transitions In Project (TIP)1 decided to form a CoP around the design, assessment and management of large first year units.

A Malaysian tale : pre-service teacher education and ICT integration for a better world

The use of Information and Communication Technologies (ICT) in education is often a topic of much discussion within all sectors of education with educators and educational researchers continually looking for innovative ways of using these technologies to support and enhance student outcomes in education. Consequently, Malaysia is no exception to this and as the Ministry of Education (MOE), Malaysia strives to meet its government’s Vision 2020, educational reform across all educational sectors has become imperative. ICT will play an integral role in the educational reform process and teacher education programs are no exception to this. ICT and capacity building will play an important role in the re-conceptualisation of teacher education programs. This paper reports on how a collaborative capacity building project between two Malaysian teacher education Institutes and an Australian University has given lecturers and pre-service teachers an opportunity to redefine their use of ICT in their prospective teaching areas of science, mathematics and design and technology. It also highlights the positive capacity building programs that occurred between both Australian university lecturers and Malaysian Institute lecturers and how this contributed to the effective integration and use of ICT.

Joint venture behaviour in construction industry : an Australia case study

Joint ventures can take many forms and can be formed for different reasons, from sharing resources to creating future business opportunities. At the same time, there is increasing interest and discussion of alternative procurement methods, moving away from traditional procurement systems to relational approaches. Business systems and strategies need to be redefined and move from a short-term project to project culture to a more strategic, long-term perspective. Joint ventures of construction organisations, global and local, have become increasingly popular to deliver large-scale infrastructure construction projects. However, successful strategic collaborations require project organisations to formulate a fit between contractual and operational arrangements for each situation. This study reviews the movement from traditional procurement methods towards relational contracting approaches in Queensland, Australia. The study examines the organisational factors that facilitates sustainable relationship between project organisations and hence, lead to long-term business success. This paper reports on initial findings captured from a survey undertaken with construction contracting organisations in Australia, focusing on the supply chain relationships. Contractors’ perceptions of the relationship management process and the engagement of the supply chain are also presented.

The impact of property title type on residential property returns

Residential property in New Zealand comprises both freestanding residential properties and medium to high density residential properties. Medium to high density residential property comprises the typical units, townhouses and semi-detached houses common in most residential property markets. However, in many of the larger cities of New Zealand the free standing residential property market has evolved into two separate markets being freehold residential property and cross lease residential property. Cross leases have developed as a form of infill housing to reduce the urban sprawl in major canters, while reducing the time and cost for residential property developers. A cross lease is created when an existing freestanding residential property subdivides a portion of the existing land for the erection of another house on the original title, basically dividing one larger residential section into two smaller residential blocks. This paper will analyse house prices in Christchurch over the period 1992 to 2006 to determine if the various housing markets have shown similar capital returns or if there is a specific preference for a particular residential property title.

What advertisers need to know about the iYGeneration : An Australian perspective

A great challenge exists today: how to reach youth (a.k.a. the iYGeneration) who consume multiple media concurrently, who can access information on demand, and who have intertwined virtual social media networks in their lives. Our research finds that Australian youth multi-task and rarely use traditional media, although significant differences between males and females, as well as late tweens and 20-somethings, exist. Technology convergence facilitates two-way dialogue, allowing growing social interactions to occur in their technological environments. Our findings show that in order for marketing communication professionals to effectively communicate with this market, it is crucial to know exactly how the iYGeneration use media, which media they use, and when they use it.

AITPM Email Newsletter Volume 0905, June 2009 : President's Message

President’s Message Hello fellow AITPM members, Due to three colliding forces of nature I find myself writing this month’s message from home – today, I am still getting over a persistent virus that seemed to set in just after returning from Singapore a couple of weeks ago, which my diabetes won’t let me get away with too easily (no Kermit the Frog swine flu jokes please). Combine this with a very wet day in Brisbane – in fact the wettest for 20 years (how can we complain, except for flash flooding?). And in Queensland today is a state school teachers’ strike, so one half of our brood is over watching TV. Family snapshots aside, the biggest news for our industry of late is the $8.5 billion announced in the Federal Budget for transport infrastructure projects; many “shovel ready”, but some – and fortunate for our profession – desktop ready. This newsletter provides nationwide coverage on the transport infrastructure aspects of the Federal Budget. We’ll need a bit more time to carefully look at the ensuing State Budgets’ announcements. Regarding the federal budget announcements, I am pleased to see serious attention being paid to upgrading the M1 system – I hope to see a motorway standard facility connecting Adelaide to at least Rockhampton in my lifetime. But some other important roads are of course missing out in this particular budget. Various levels of commitment are being made to urban passenger rail – some project significant while others planning significant. Enhancement of suburban rail is important across the capitals and Australia’s medium sized cities such as the Gold Coast and Newcastle. Not much on road safety initiatives jumped out at me, but I believe it is implied in the large road projects and in some of the detail elsewhere. I do believe it’s about time a ‘Vision Zero’ style policy is adopted at the National level, since any death is unacceptable on the road, just as it is in any other workplace. So, overall some good news on building transport infrastructure to keep the economy purring during this recession, and strongly supporting it during future boom times. The other edge to the sword, of course, is that we tax payers will be paying a considerable amount for borrowings for these projects over a long period of time. I close again in reminding everyone again that AITPM’s flagship event, the 2009 AITPM National Conference, Traffic Beyond Tomorrow, is being held in Adelaide from 5 to 7 August. www.aitpm.com has all of the details about how to register, sponsor a booth, session, etc. Best regards all, Jon Bunker

Dynamic Lock Synchronisation for collaborative 3D applications

In a typical collaborative application, users contends for common resources by mutual exclusion. The introduction of multi-modal environment, however, introduced problems such as frequent dropping of connection or limited connectivity speed of mobile users. This paper target 3D resources which require additional considerations such as dependency of users' manipulation command. This paper introduces Dynamic Locking Synchronisation technique to enable seamless and collaborative environment for large number of user, by combining the contention-free concepts of locking mechanism and the seamless nature of lockless design.
