The Australian Defence Force has embarked on an ambitious capital program to provide our nation with future generations of warfighting capability. The Continuous Naval Shipbuilding program and the Land Combat Vehicle programs headline the ambitions for generating sustainable sovereign capacity.
Through lessons learnt from previous programs, including the Collins Class submarines and ANZAC Frigates, Australia has taken a deliberate and integrated approach to strategic capability investment and industry planning to guide the delivery of the future capability.
There is a demonstrated intent to ensure that the programs deliver more than just capable platforms and that the fundamental inputs to capability are integrated from the start of the programs. The approach is exemplified by:
Development of Sovereign Capability through a deliberate and planned implementation of Australian Industry Capability
Developing procurement strategies that support a sustainable and enduring industrial base
Substantive decisions are now being made that will shape the delivery of capability for decades. Each program on its own is challenging and complex, yet many of the decisions around facilities, infrastructure, workforce, and supply chains require an enterprise approach. The complexity of systems, processes and concepts provides the opportunity for decision support tools to support choices that will shape the next generation of capability.
The Australian Defence enterprise is embracing modelling and simulation to support sound capability, acquisition and support system decision making.
Examples of different decision support applications of Discrete Event Simulation are:
Ensuring that the timing of infrastructure implementation does not impact the project or program schedule
Analyse Vessel Usage Upkeep Cycles to optimise operational availability. Achieving two extra operating sea days annually per platform equates to two additional years of active availability over a class lifecycle.
Test armoured fighting vehicle geographic disposition and transport options to ensure cost-effective availability meets the training and operational requirements.
Why use Discrete Event Simulation
Discrete Event Simulation models the operation of a system that is driven by activities occurring at discrete instants in time (an event). It models and simulates the performance of real-life processes, facilities or systems and allows “what if” scenarios for problems of increasing size and complexity to be tested and compared. The ability to focus on events enables the simulation of an entire process or capability lifecycle. Minor improvements can equate to substantial savings across an enterprise’s capability lifecycle.
Uncertainty and risk can be incorporated into the model, providing a thorough examination of the system. The modelling is easily verified, and results are presented quantitatively but importantly visualise the simulation, supporting stakeholder understanding and trust.
Developing a model provides the customer with a different and occasionally new perspective on existing processes and systems. The initial steps require a thorough and complete understanding of the existing or proposed system or process and force both the client and the modelling team to examine each step critically. The modelling process requires a collaborative approach.
Typical steps in developing the model and subsequent simulation and analysis is as follows:
Customer objectives and requirements are defined.
Data collection and analysis to create an accurate representation of the system or process being modelled.
Model development is usually based on the existing system.
The model is verified and validated.
Options and scenarios are simulated.
Results are analysed, and recommendations are developed.
The initial steps are essential to maximising the effectiveness of the simulation and need an engaged and knowledgeable customer to define the objectives. The customer may choose to deliver the model and perform the simulation themselves, especially when the underlying data is confidential.
