The problem analysis step of designing an agent-based model It is the identifying of specific problem that the model aims to address, defining its scope, and determining the information it should provide to support decision-making.
It involves
a. Clearly defining the problem,
b. Formulating specific questions that the model should be capable of answering,
c. Identifying the type of information that stakeholders need, and considering the involvement of stakeholders in the design process.
d. Exploring existing theories or hypotheses that can guide the design of the model and assessing whether there are any existing "generic" models that can be adapted or reused for your specific problem can also be helpful
