WIPO Patent Application WO/2021/016989

A1

A system including a first computing device, at least one processor, and a memory. The first computing device is configured to generate historical driver data associated with a driver. The operations performed by the at least one processor includes obtaining the generated historical driver data associated with the driver. Based at least in part on the obtained historical driver data, a value function is estimated. The value function is associated with a plurality of multi-driver order dispatching policies. An optimal multi-driver order dispatching policy is then determined. The optimal multi-driver order dispatching policy is associated with an estimated maximum value of a plurality of utility scores incorporating driver rewards, user experience, and an estimation of a value function. The estimation of the value function applies a cerebellar model arithmetic controller.
