ABSTRACT

In this talk, I will discuss my recent work on last-mile delivery systems with innovative zoning and coordination schemes. In the first part, I will discuss data-driven optimization models to partition the service region to improve response time and service equity. In addition to theoretical performance guarantees, the framework has been successfully implemented for a leading logistics company in Southeast Asia. The second part of the talk will present ideas on coordinating last-mile delivery jobs with other business operations, including ride-hailing and assortment. In particular, I will describe a collaboration with a meal delivery platform, which leads to a new optimization model that connects delivery service operations and assortment planning decisions. This model has been validated with a field experiment in the Vancouver metropolitan area.
