Query: Multi-Agent Reinforcement Learning for Order-dispatching via
  Order-Vehicle Distribution Matching   Improving the efficiency of dispatching orders to vehicles is a research
hotspot in online ride-hailing systems. Most of the existing solutions for
order-dispatching are centralized controlling, which require to consider all
possible matches between available orders and vehicles. For large-scale
ride-sharing platforms, there are thousands of vehicles and orders to be
matched at every second which is of very high computational cost. In this
paper, we propose a decentralized execution order-dispatching method based on
multi-agent reinforcement learning to address the large-scale order-dispatching
problem. Different from the previous cooperative multi-agent reinforcement
learning algorithms, in our method, all agents work independently with the
guidance from an evaluation of the joint policy since there is no need for
communication or explicit cooperation between agents. Furthermore, we use
KL-divergence optimization at each time step to speed up the learning process
and to balance the vehicles (supply) and orders (demand). Experiments on both
the explanatory environment and real-world simulator show that the proposed
method outperforms the baselines in terms of accumulated driver income (ADI)
and Order Response Rate (ORR) in various traffic environments. Besides, with
the support of the online platform of Didi Chuxing, we designed a hybrid system
to deploy our model.
