講座預告 | 劉哲:三方市場——外賣平臺的定價、人員編制和路徑問題

講座地點:天津大學第25教學樓A區3B教室

講座內容:近些年以DoorDash、Uber Eats和美團點評為代表的送餐平臺通過有效匹配分散在地理上分散的餐館、顧客和外賣員而快速發展。我們研究在三方自主決定參與情況下送餐平臺的聯合定價、人員編制和路徑優化問題。通過采用狀態依賴的排隊論模型——服務速率取決于空間摩擦導致的三方不平衡——我們研究了大型系統在繁忙交通(Heavy Traffic)下的均衡表現,通過漸進分析來展現平臺如何平衡配送使用率和服務質量。我們發現送餐平臺的價值主要體現在三方面:(1)通過吸引提高下單量和更快的配送增加市場產量;(2)節省餐館的物流成本并提高外賣員的使用率;(3)通過路徑優化減少跨區配送占用的外賣員數量,從而減少顧客等待時間和外賣員的空閑時間。

Motivated by the proliferation of food delivery platforms, such as DoorDash, Uber Eats and Meituan-Dianping, that match restaurants, customers and delivery drivers over a geographically dispersed network, we study the platform’s joint pricing, staffing and routing problem under endogenous participation of all three sides. Using a state-dependent queueing model where the service rate depends on the imbalance of the three sides due to spatial frictions, we study the equilibrium behavior of a large system in heavy traffic and show through asymptotic analysis how the platform controls balance capacity utilization and service quality. We show the platform’s value is threefold: (i) increased market output as the platform boosts demand for restaurants and offers faster delivery; (ii) delivery resource pooling that saves the restaurants’ logistic costs and increases deliverer utilization; (iii) efficient network routing that reduces cross-location pickups, hence customer waiting and deliverer idleness.
