The patrol boat scheduling problem with complete coverage (PBSPCC) is concerned with scheduling a minimum size fleet of resource-constrained vessels to provide ongoing continuous coverage over a set of maritime patrol regions. The problem is complicated by the necessity for patrol vessels to visit replenishment stations (ports) on a regular basis for mandatory resource replenishment. This problem, which is applicable to maritime border protection and surveillance operations, has its origins in fleet sizing questions raised by the Royal Australian Navy (RAN) and has been a subject of interest for the authors since 2008.
Our scientific and technical publications are an important vehicle for the dissemination of our work.
We have several goals for our publications:
- To communicate the results of the research program to clients and fulfil our reporting responsibilities to the Department of Defence.
- To record the results of our research program.
- To communicate the results of scientific research and technical information to Australian industry and academia.
- To increase awareness of and enhance the reputation of DST Group.

The Defence problem space has expanded considerably in recent years, with the operating environment now ranging from cooperation through to conflict, often with blurred boundaries in between. Additionally, the physical domains of air, land and sea have been expanded to include information and cyber and space. Defence seeks new sources of adversarial advantage to prevail in this contested environment. New operations analysis approaches are required to provide meaningful evidence-based decision-support associated with this problem space.
This paper is intended to contribute to both the dialogue around the use of AI in the ADF, as well as to provide a useful resource for ADF members to enhance their education and understanding about the technologies of artificial intelligence, with a particular focus on deep learning.
The Defence Science and Technology (DST) Group Transonic Wind Tunnel (TWT) in Melbourne was built in the late 1990s and commissioned in 2000. This facility has since been used in a variety of experimental aerodynamic test campaigns to support the Australian Defence Force (ADF), particularly associated with stores clearance and aerodynamic investigations of military aircraft and missiles.
This technical note considers a sensor that alternates randomly between working and broken versus a target that reluctantly gives away glimpses as a homogenous Poisson process.
This study investigated information exchange and processing under the pressures and limitations of first respondents at the tactical edge to provide insight into transitioning reference information to a dynamic 'real-time' paradigm.
This technical note considers processes that alternate randomly between 'working' and 'broken' over an interval of time.
This report thus investigates the subject of factor screening, for stochastic simulation models, and overviews several solutions to this problem. In particular, sequential bifurcation will be shown to provide a very efficient approach to the problem of factor screening, in comparison to standard one factor at a time classication methods.
Body armour is used by police and military personnel to provide passive protection of the vital organs of the thorax and abdomen against ballistic, fragmentation and stab threats. Optimising the amount of coverage provided by body armour requires consideration of the trade-off between the passive protection afforded by the armour and its potential to hinder wearers' ability to actively protect themselves.
