Abstract

The vision of “smart cities” has been pursued worldwide to transform urban habitats into superior efficiency, quality, and sustainability. We argue that the smart-city movement will transition from the tech-oriented stage to the decision-oriented stage. Hence, a smart city can be perceived as a system scope within which planning and operational decisions are orchestrated at the urban scale, reflective of multi-dimensional needs, and adaptive to massive data and innovation.

To exemplify the above notion of smart cities, in this talk, I will present two recent essays.

The first essay is about electric vehicle battery swapping systems: Battery swapping is reviving and thriving in our cities. Some Chinese cities are embracing an emerging infrastructure network called “swap-locally, charge-centrally” to resolve the tension among service proximity, battery availability, and grid accessibility. In this paper, we model this new infrastructure network as a joint location and repairable-inventory model to understand its cost and environmental implications.

The second essay is about retail on wheels, or the so-called “stall economy”: Urban open space emerges as a new territory to embrace retail innovations. Selling products in public spaces with wheeled stalls can potentially become ubiquitous in our future cities. Transition into such a “stall economy” paradigm is being spurred by the rapidly advancing self-driving technologies. This paper provides spatial-queueing models, theory, and insights concerning how to deploy and operate autonomous wheeled vending stalls to scale up the stall economy.
