Towards a dynamic assessment of raw materials criticality: Linking agent-based demand - With material flow supply modelling approaches

► Current criticality assessment methods provide a 'snapshot' at one point in time. ► They do not account for dynamic interactions between demand and supply. ► We propose a conceptual framework to overcomes these limitations. ► The framework integrates an agent-based behaviour model with a dynamic material flow model. ► The approach proposed makes a first step towards a dynamic criticality assessment.
