The scale of the logistics and coordination required for the build-up and transition from peace to operations presents complex problems for military logistic planners. The key challenge for DSTA was to study and propose means to identify and address bottlenecks, while meeting logistic throughput and mission timing with minimal resources. The DSTA team used Modelling and Simulation (M&S) as the primary tool to study and address these challenges. Due to the scale and complexity of the problem, an overarching framework was first developed to outline a systematic and rational approach to phase in the M&S solution over time.
The team then developed and adopted three different sets of overarching artefacts – including activity maps, time maps and workflow process diagrams – to encapsulate the breadth and dynamics of integrated logistic planning.
The activity maps draw out the connectivity among the key activities within and across the SAF’s air, land and sea domains, while the time maps provide the intensity of the activities across the different buildup stages. The workflow process diagrams also highlight the various resources and supply chain concept supporting the integrated logistic plans.
Based on these overarching artefacts, the team was able to frame the integrated logistic plans holistically. By piecing the connectivity, time elements, processes and strategic resources together, the team was able to identify issues ranging from vulnerability and resource bottlenecks to dependency on external factors. Thus, the foundation and framework for developing the M&S solution was built to enable the SAF to achieve seamless transition from peace to operations.
