Formulation and analysis of dynamic supply chain of backfill in construction waste management using agent-based modeling

•This paper proposes two optimization models to solve a dynamic supply chain issue.•The outcomes help reuse and recycle backfill, a major type of construction waste.•The models are based on mathematical programming and agent-based modeling.•The comparative study illustrates the performance of both approaches.•Agent-based modeling is more capable of analyzing the dynamic supply chain.
