Order dispatching method and device and storage medium

The invention provides an order dispatching method and device, and a storage medium. The method comprises the steps of obtaining the remaining assessment time and available riders of each current unallocated order; taking the unallocated orders as nodes, clustering the nodes according to the categories of the nodes, filtering out the orders with only one node and the remaining assessment time greater than a preset value, and obtaining a final cluster of the orders; and obtaining a cost matrix based on the final cluster and the available riders, and updating the cost matrix after the class order corresponding to the minimum cost is delivered to the optimal rider selected by the cost matrix until all classes are traversed. According to the scheme of the invention, the hierarchical clustering algorithm based on geographic information is utilized to carry out order combination, and then the cost matrix is generated to select the optimal rider for delivery. The order sending result better conforms to the behavior habits of the rider, and the experience of the rider and the efficiency of executing the distribution task by the rider are improved. Moreover, the order dispatching objective function estimation is more accurate, and the KPI index of the dispatching system and the order delivery punctuality rate are improved.

Parking lot guidance system and method set with threshold value

The invention discloses a parking lot guidance system and method set with a threshold value. The parking lot guidance system mainly comprises a threshold value enabling module and a parking space guidance module, wherein the threshold value enabling module sets a threshold value of the parking lot guidance system by adopting an Agent based modeling method; if the parking space occupation ratio isless than the threshold value, the parking space guidance module is not enabled, and a vehicle owner searches a parking space by himself; and if the parking space occupation ratio is greater than or equal to the threshold value, the parking space guidance module is enabled. The parking space guidance module is composed of a parking lot positioning subsystem and a path planning subsystem, wherein the parking lot positioning subsystem is used for obtaining position coordinates of a vehicle, and the path planning subsystem guides the vehicle owner to reach the parking space by adopting a Floyd algorithm. The parking lot guidance system enables parking lot resources to be effectively allocated, reduces the operation cost of the system, improves the circulation efficiency of vehicles and improves the economic benefits of the department to which the parking lot belongs. Meanwhile, the parking lot guidance system improves the intelligent level of the parking lot, conforms to behavioral habitsof vehicle owners, reduces the parking and vehicle searching time of the vehicle owners and improves the personal efficiency.
