exposures to chemicals in consumer products and in indoor environments. Herein we create
an agent-based model (ABM) that is able to simulate longitudinal patterns in behaviors. By
basing our ABM upon a needs-based artificial intelligence (AI) system, we create agents that
mimic human decisions on these exposure-relevant behaviors. In a case study of adults, we
use the AI to predict the inter-individual variation in the start time and duration of four …
