42  Introduction

In this module, we explain and demonstrate multi-layer networks in EpiModel. Multi-layer networks are those with the same node set but different edge set. Multi-layer networks allow for flexible handling of epidemic models in which there are different types of contacts that require different network configurations, and specifically different terms in their formation and dissolution models. There may also be interaction between layers, such as in the case where the dynamic network structure in one layer influences the dynamic network structure in another layer. We start by walking through applied examples of multi-layer networks in our research and then demonstrate the methods for implementing them in EpiModel.
