The success of e-commerce business offering same-day delivery depends on customer satisfaction. To speed up deliveries and lower costs, some companies have been using private individuals as non dedicated drivers to perform pickup and delivery tasks for online customers. Such delivery systems are known as crowd-shipping. Customers have come to expect an accurate estimate for the delivery times of their online orders. The coordination of online deliveries with private individuals is done by a crowd shipping platform. In this paper, we focus on the estimation of pickup and delivery times. This is a challenging job because not only are the requests unknown and submitted dynamically, but so is the pool of drivers, i.e. delivery capacity. We model the problem as a Markov decision process and integrate it into a simulation study. To improve the estimates that can be done by a naive policy, we propose two policies that use lookahead: one with a fixed lookahead horizon and one with a dynamic. Our numerical experiments demonstrate that a lookahead policy with dynamically adjusted horizon outperforms the other two policies in terms of estimation accuracy, which is up to 19% higher in some instances.(c) 2022 The Author(s).
