Modeling of Supply Chain Networks

Traditionally optimizations in Supply Chain Management (SCM) were approached by mathematical modeling to describe and predict overall system dynamics. However, especially in large supply networks, with hundreds of independent actors, this modeling approach is insufficient to capture multi-objective, often competing dynamics based on differential equations.

More recently, the concept of Big Data was applied to SCM. The availability of large sets of heterogeneous data from all points within the supply chain gives rise to the expectation to detect patterns that give new insights in the functioning and relations. Big Data analysis through clustering, time-series prediction, correlations, and other algorithms offer important tools for decision makers to base decisions upon facts rather on intuition.


While an important “toolset”, Big Data refers to data collected from existing supply networks. However, such networks are also evolving over time meaning that the network members as well as the structures change. To address this problem agent-based modeling is applied to model the supply network as a set of agents that (inter)act based upon their own objectives. The interactions of the agents then give rise to the overall system dynamics, including new relations (structures) or even new network members.

Hence, the goal of this project is to better understand how supply networks evolve and how agent-based models can be used to support strategic decision making.
