Simulation Modelling

A simulation model provides a dynamic, detailed view of operations within and across organisations. It allows processes and systems within the model to be visualised and verified by the appropriate stakeholders.

By visualising a system in detail, simulation models support a common understanding of the way things work, presenting complex behaviours in a way that would be lost in static spreadsheet modelling.

At InterDynamics, we have developed a wide array of simulation models, from simple factory operations to complex pit-to-port supply chains, incorporating multiple mine operations, rail networks, stockpiling and shipping.

We have a wealth of experience in modelling rail networks, creating detailed models of train movements, from single lines to a nationwide network.

By simulating using discrete events, as opposed to operational averages, we provide models with greater integrity to the real behaviour of the system. When multiple systems interact, dynamic simulation provides a view of the extreme variations in conditions that can be encountered giving a clearer understanding of the system as a whole.

Simulation models can be used in a variety of ways:

Capacity planning
A simulation model can help an organisation determine how big an asset should be, or how many assets are required. This assists in finding an appropriate balance between capital investment (the cost and size of assets) and operational requirements.

Business interruption assessment
Simulation models are an effective way to assess the impact of business interruptions. By triggering specific interruptions, rates of recovery and lost capacity can be determined, leading to a better management of risks and enhanced understanding of the robustness of operations.

Exploring alternative operational modes
Dynamic modelling allows users to explore alternative modes of operations or business rules by posing ‘what if’ scenarios. Through the rigorous investigation of potential scenarios, businesses can see how their systems will behave under alternative conditions, before implementation in the real world.

Scheduling and rostering
Scheduling and rostering can also be incorporated into simulation models, using progressive layering. This is an advanced scheduling technique that is often utilised by InterDynamics and presents progressive solutions from the most constrained asset or activity, to the least constrained.
