Home » Case Studies » Mathematics to Assist Fleet Planners


Defence Science and Technology Group (DST) is collaborating with the University of Melbourne to access the specialist skills of PhD student, Nick Davey. The project is one of 100 APR.Intern internships DST will support over the next four years.

Nick is working with Joint and Operations Analysis Division (JOAD) scientists, David Marlow and Joyanto Mukerjee, on scientific methods to assist Defence aircraft fleet planners.

The team’s aim is to provide a range of scientific techniques to help military aircraft fleet owners improve their ability to meet the requirements at all stages of their fleet’s life.

“The project will provide a robust predictive capability which will also reduce the workload for fleet planners,”


Dr David Marlow, DST Group Senior Operations Research Scientist

For the problem Nick is working on, a monthly planning horizon of three to four years is considered. The project’s aim is to develop an optimal plan for a fleet of military aircraft for this timeframe, with the objective of meeting all ongoing requirements regarding flying and deployments. Aircraft may rotate between multiple squadrons, where each squadron may have different flying and fatigue loans.

“Nick is applying his PhD skills to improve the existing model formulation and solution quality,”


Dr David Marlow, DST Group Senior Operations Research Scientist
