Maximizing Dimensional Efficiency With Minimal Cardinality Pattern Combinations. Making optimal use of dimensional capacity is often fundamental to the efficiency of processes in science and industry. Many important applications use combinations of patterns to achieve this. For example, in paper and in steel manufacturing, reels are divided lengthwise into cutting patterns, combined so as to minimize waste. In medicine, radiation patterns are combined to effectively treat cancerous tumours. ....Maximizing Dimensional Efficiency With Minimal Cardinality Pattern Combinations. Making optimal use of dimensional capacity is often fundamental to the efficiency of processes in science and industry. Many important applications use combinations of patterns to achieve this. For example, in paper and in steel manufacturing, reels are divided lengthwise into cutting patterns, combined so as to minimize waste. In medicine, radiation patterns are combined to effectively treat cancerous tumours. By addressing the common mathematical structure underlying pattern combination, this project will account for a hitherto neglected critical factor - the solution cardinality - making fully optimized solutions available for the first time to many applications in science and industry.Read moreRead less

This project extends previous research addressing mathematical challenges in the optimal design and scheduling of robotic instrumentation. The Partner Organisation manufactures instruments for cancer diagnostics, and designs instruments that need to produce rapid, high-quality results, at a reasonable cost in a competitive market. It is intended that powerful new scheduling algorithms will be devised to handle their complex problem, which is more challenging than standard problems. The developed methodologies aim to reduce the product development cycle and boost the competitiveness of Australian manufacturers. In addition, new theoretical and algorithmic contributions aim to enable improved scheduling in other application areas.Read moreRead less
An integrated mathematical approach to synchronise and optimise hospital operations. This project aims to develop an integrated mathematical approach to synchronise and optimise patient scheduling systems of different departments to ensure that the hospital’s assets and related resources are used efficiently. The project’s aim is to investigate patient flow, process delay, and the interaction and inter-dependence of departments within the hospital to reduce access block (bottleneck) and subseque ....An integrated mathematical approach to synchronise and optimise hospital operations. This project aims to develop an integrated mathematical approach to synchronise and optimise patient scheduling systems of different departments to ensure that the hospital’s assets and related resources are used efficiently. The project’s aim is to investigate patient flow, process delay, and the interaction and inter-dependence of departments within the hospital to reduce access block (bottleneck) and subsequent overcrowding. This project aims to smooth the running of the hospital, improve the efficiency of patient throughput, reduce waiting times, and revolutionise hospital planning and scheduling.Read moreRead less
Optimisation of Rail Network Infrastructure Capacity under Dynamic Train Planning. Recent changes in railway operating environments have caused significant operational and management problems in Australia. This research will lead to improvements of railway's key managerial functions, namely: network capacity planning; rollingstock planning; train scheduling; and maintenance planning. The major outcome of the research will be to develop an optimisation model to significantly improve the operati ....Optimisation of Rail Network Infrastructure Capacity under Dynamic Train Planning. Recent changes in railway operating environments have caused significant operational and management problems in Australia. This research will lead to improvements of railway's key managerial functions, namely: network capacity planning; rollingstock planning; train scheduling; and maintenance planning. The major outcome of the research will be to develop an optimisation model to significantly improve the operating efficiency and assets productivity of Australia's rail system. The novelty of the research is that it will be undertaken using innovations based on modern job shop scheduling and sequencing optimisation techniques as the complexity of the problem makes it impossible to solve by classic optimisation techniques.Read moreRead less

Forensic management approach to rework mitigation and prevention in construction. Rework is the unnecessary effort of re-doing a process or activity. The direct costs of rework in construction have been reported to be as high as 25% of project costs. These rework costs would be higher if they included the intangible, but real costs of disruption caused by schedule delays, litigation, and dysfunctional contract relationships. To reduce rework in construction projects a forensic project managem ....Forensic management approach to rework mitigation and prevention in construction. Rework is the unnecessary effort of re-doing a process or activity. The direct costs of rework in construction have been reported to be as high as 25% of project costs. These rework costs would be higher if they included the intangible, but real costs of disruption caused by schedule delays, litigation, and dysfunctional contract relationships. To reduce rework in construction projects a forensic project management model that can be used to stimulate learning and process improvement will be developed, evaluated and validated. This will enable the design of strategies to reduce rework and improve the overall performance of projects.Read moreRead less
Determining features that separate groups of protein sequences. This project aims to develop mathematical approaches for determining features that distinguish one group of proteins from another, based on their amino acid sequences. The groups of sequences will reflect different outcomes, so that identifying the fundamental features can result in targeted interventions against the poorer outcome. A simple comparison at each position or of known features can fail to determine robust differentiator ....Determining features that separate groups of protein sequences. This project aims to develop mathematical approaches for determining features that distinguish one group of proteins from another, based on their amino acid sequences. The groups of sequences will reflect different outcomes, so that identifying the fundamental features can result in targeted interventions against the poorer outcome. A simple comparison at each position or of known features can fail to determine robust differentiators and so more complex methods are required. The project will, for example, help identify HIV vaccine targets by comparing early HIV transmission sequences from those in chronic infection. The methods will be applicable to viral proteins where high mutation rates make this task even more complex.Read moreRead less

Summary
New integer programming based theory, formulations and decomposition techniques with applications to integrated problems. Optimisation problems permeate science and industry. By developing new techniques to solve larger and harder problems than is currently possible, more complex questions can be answered, and more accurate solutions obtained. Industries can use such tools to make better financial, resource management, operational, and/or strategic planning decisions.
Operations research without convexity. Operations Research (OR) is one of the most applicable areas of mathematics and of importance for the future of technologically advanced Australia. However, applications of OR often require convexity. This is a serious limitation.
