ABSTRACT:

On-demand food delivery (OFD) services have experienced a significant surge in popularity in recent years, which poses various operational challenges for service operators such as Meituan, Doordash, among others. Many studies have been established to investigate this new type of urban transportation. However, the OFD related literature is still at an early stage where there lacks fundamental study in decision-making analysis, network equilibrium analysis, empirical analysis, etc. In this talk, three recent research works of my research group will be introduced. First, an analytical model will be presented. It captures the complex interplay of the OFD system by considering adjustable service region size, order bundling, and batch-matching processes. Various managerial insights are derived in mathematical language and depicted in numerical experiments. Second, the OFD service is analyzed in a network context, where the spatial heterogeneity and network effects are well considered. In the network model, drivers’ traveling behavior appear to be more complex since it involves both individual choice behaviors and the dispatching decisions from the platform. The three market players and a central platform are modeled in a Stackelberg leader-follower game structure where their behaviors and the network matching equilibrium are analyzed. Finally, we study the uncertainty of the OFD service, specifically on the customers’ order cancellation behaviors. Our findings reveal distinct cancellation patterns across different stages of the order fulfillment process: the matching and pick-up stage.
