The purpose of this paper is to use the Agent Based Approach to analyze the Global Apparel Supply Chain system. Through this paper, I will use DSRP analysis to understand the system as it is, POSIWID analysis to compare the current system to the aspirant system, and CAS analysis to define the agents of the system. With these analyses methods, I will illustrate where interventions can be made within the supply chain system to alter the system structure from a linear to circular model. Through this change in system structure, these recommendations will address the emergent behaviors of the supply chain system through circularity and sustainability initiatives.
