Our structural model of the urban system is shown in Figure 1, with the overall system treated as a set of subsystems providing resources and/or services: utility, transportation, public services, etc. The Residential Subsystem, for example, provides labor as a service to other services. Each of these subsystems is further decomposed, i.e. utilities include water

Effective systems development begins with a clear set of objectives, captured as requirements. In terms of building a model, we must consider several different types of requirements: Model Architecture requirements – which urban systems should be part of the model Model Simulation requirements – which performance factors should be calculated Urban System requirements – what

Modeling urban communities has been designated as a high priority target for improved systems engineering . World population is increasingly urbanized. In the US, the percentage of the population in metropolitan areas has shifted from 7% in 1820 to 51% in 1920 to 82% today. China looks to make the same shift
