Dairy supply chain in west Java: Modelling using agent-based simulation and reporting using the stress guidelines

Agent-based simulation (ABS) is one of the preferred methods to model supply chains, especially when we are interested in estimating the impact of the interactions between individuals on system level outcomes. This paper presents a case study in which ABS is used to model the dairy supply chain in West Java. The characteristics of the supply chain in this case study, such as, the existence of forage as a common resource and the dominance of smallholder farmers, are different from most dairy supply chains in higher income countries. It is more common in low-middle income countries. ABS is used because we are interested in analysing the behaviour of the farmers, in particular, their buying and selling decision rules, and their impact on cow population and milk production. This paper demonstrates how the STRESS guidelines can be used to report the simulation study.
