Events Thursday 1st June - "Rail Mounted Gantry Crane Scheduling at Port Botany" with Gary Froyland Thursday 4th May - The Cross City Tunnel with Geoff Phillips Wednesday 29th March - "Operations Analysis in Defense" with Charles Newton Thursday 1st June - "Rail Mounted Gantry Crane Scheduling at Port Botany" with Gary Froyland Time and Date 6pm for 6:30pm 1st June Place Room 1553, Level 15 Building 1 (Tower), University of Technology, Sydney, Broadway Abstract We outline work carried out to schedule the movement of import/export containers from ship to train/truck and vice-versa at Port Botany. We break the problem into a strategic part and tactical part. The strategic part is solved as an integer program and the tactical part is solved using online methods. Gary Froyland is a Senior Lecturer in the School of Mathematics at UNSW. His current OR work is concerned with scheduling via integer programming with applications in mining and ports. Thursday 4th May - The Cross City Tunnel with Geoff Phillips Time and Date 6pm for 6:30pm 4th May Place Room 1553, Level 15 Building 1 (Tower), University of Technology, Sydney, Broadway Abstract The Sydney Cross City Tunnel has become a thorn in the side of the public, the government and not the least the tunnel operator. Few people believe that a solution to please all parties is possible. There seems to be a lack of analysis of the problem, other than to criticise original forecasts of traffic numbers and the provisions of the contract relating to road closures. This paper makes use of the data collected on traffic numbers for the $3.50 toll, no toll and half toll of $1.75, together with the estimate of 90,000 cars per day for the operation of the tunnel to be commercially viable. The basic economics of monopoly pricing are a starting point for the discussion. A simple mathematical model is used to draw conclusions about the future commercial viability of the tunnel. Finally a solution is proposed, which differs very much from the present approach by the State Government. Geoff Phillips retired from DSTO as a Senior Research Scientist in August 2000. Since then he has been occupied teaching mathematics part-time at Sydney University. Last year Geoff also spent a short time as mathematics consultant to the Channel Seven series "Headland". Wednesday 29th March - "Operations Analysis in Defense" with Charles Newton Time and Date 6pm for 6:30pm 29 March Place Room 1553, Level 15 Building 1 (Tower), University of Technology, Sydney, Broadway Abstract The discipline of Operations Research/Analysis has its origins in Military/ Defence analysis. Through the past 65 years or so one has seen the private and public sectors also benefiting from the input of OA in decision making and problem solving. In the Australian Defence environment one has observed the popularity of OA wax and wane. At present OA is experiencing some renaissance in Defence. The reasons for this could be the result of better approaches to defence problem solving, the acceptance by Defence sponsors of its applicability, and the need to reduce costs associated with major acquisitions. The emphasis of this talk is to discuss some of these reasons and how one may maintain the relevance of OA to the community in particular Defence. Charles graduated from the Department of Nuclear Physics, ANU in 1975. The next three years he continued in the department as a Research Fellow. In 1978 Dr Newton joined the Department of Defence as a Research Scientist in the Analytical Studies Branch. He remained in the Department of Defence as a Senior Research/Acting Principal Research Scientist. In 1982 he attended the Joint Services Staff College course. In 1987 Dr Newton joined the then Department of Computer Science as a Senior Lecturer in Operations Research. In May 1993 he was appointed Head of School and a few months later Professor of Computer Science. In 2001 he was appointed Deputy Rector (Education). During this period Professor Newton has taught at both undergraduate level and postgraduate level. The subject material that Professor Newton has covered in these lectures includes operations research/management science, simulation, modelling, problem solving, decision support systems and information systems. In July 2002 he stepped down as Deputy Rector and on 27 February 2003 he retired. At present he is an Emeritus Professor within the School, where he continues to lecture, carry out research and undertake some consulting work for government and private industry.
