Published by: The Australian Society for Operations Research Inc. In this issue, J Kamruzzaman and R Sarker have contributed a technical paper on Comparing ANN Based Models with ARIMA forex material composition data Prediction of Forex Rates, and we are delighted to be publishing it here as a referred paper for Bulletin readers.
Conference 2003 held at the University of South Australia, Adelaide in February this year. The 17th National Conference of Australian Society for Operations Research will be held in Sydney, as part of the 5th International Congress on Industrial and Applied Mathematics, in Sydney, during 7-11 July 2003. The details of the conference can be found in the forthcoming conference section in page 13 of this Bulletin. I am pleased to inform you that the electronic version of ASOR Bulletin is now available at this web site. Although the electronic version is prepared as an HTML file, for technical reasons articles may be in PDF or PS format. The use of computational intelligence based techniques for forecasting has been proved extremely successful in recent times. The 2003 MISG, held in the first week of February at the City East Campus of the University of South Australia, brought together about 100 professional industrial mathematicians and industry researchers for 5 days of intense collaboration.
The effects of deadlock avoidance on rail network capacity and performance for the Rail CRC. MISG 2003 was a resounding success with good progress made on each of the problems. Although it is still too early to say much about the solutions that were developed or proposed we will include a brief description of the problems and try to indicate what was achieved. Diesel electric submarines utilise a large flooded lead acid battery as a secondary energy storage medium. The battery is the only source of power for the submarine while it is submerged. The batteries are regularly charged from diesel electric generator sets that provide power for the submarine as well as for charging the batteries.
A critical issue in the operation of any organisation is the training of individuals and the subsequent training of groups that must work together to achieve large and complex goals. One of the critical issues is the hierarchical structure of the tasks, which are often divided into many subtasks. The subtasks frequently permit diverse solution methods and different tactical approaches. The use of column flotation to separate metallic particles from the original heterogeneous ores is a well-established and widely used procedure.
The column consists of two basic zones with a froth layer on top and a pulp layer below. Although some useful models have been developed to describe the capture and transport of material in the pulp the principal quantitative mechanisms that describe particle transport and fluid flow within the foam have not been successfully modelled. The K-OBM is a steel-making vessel consisting of a steel shell lined with refractory bricks. The vessel is used to convert batches of hot metal containing impure iron and steel scrap into steel by blowing oxygen through the bath. The oxidation of elements in the hot metal and scrap increases the temperature of the metal while changing its composition to that of refined steel. Queensland Rail operates a heavy-haul coal business on five rail corridors in Queensland.
The freight cost of hauling a tonne of coal varies for each rolling stock configuration. One of the main factors that influences cost is cycle time. This is the time that a train takes to travel to and from the mine and includes loading and unloading. The problem involves utilising the available rolling stock in the best possible way to find the lowest cost option. The Rail CRC is currently investigating the development of computer programs to generate optimal railway timetables. The method of generation is to use random variations on a simple despatch rule to generate a large number of possible alternative timetables.
The minimum cost timetable is then selected. A significant problem with this method is that many apparently minor variations of a feasible plan can ultimately lead to deadlock.
