Smart cities don’t happen by accident. To help planners and policy makers better understand and manage the dynamic behavior of cities, IBM Global Business Services is introducing new analytics software and services based on their “smarter cities” strategy. System Dynamics for Smarter Cities is an interactive model that allows leaders to observe how the core systems of a city -- such as the economy, housing, education, public safety, transportation, health care, government services and utilities -- work together and affect one another.
