Tire conditioning optimization for a collection of mining vehicles
First Claim
1. A system, comprising:
- a pressure sensor configured to measure a tire pressure of a tire of a vehicle;
a navigation aid configured to output a task assignment for review by an operator of the vehicle; and
a dispatch control system configured to;
receive an indication of the tire pressure of the tire of the vehicle from the pressure sensor,compare the indication of the tire pressure to a first pressure threshold and a second pressure threshold, the second pressure threshold being less than the first pressure threshold,determine the task assignment based upon the indication of the tire pressure by;
when the indication of the tire pressure is less than the first pressure threshold and greater than the second pressure threshold;
determining whether the vehicle has a current task assignment; and
when the vehicle does not have a current task assignment, determining that the task assignment is an assignment configured to cause the vehicle to navigate to a tire shop,when the indication of the tire pressure is less than the first pressure threshold and less than the second pressure threshold;
determining whether the vehicle is empty; and
when the vehicle is empty;
cancelling the current task assignment of the vehicle, and
determining that the task assignment is an assignment configured to cause the vehicle to navigate to a tire shop, andtransmit the task assignment to the navigation aid for output by the operator of the vehicle.

Abstract
A system and method includes accessing a road network database to identify a tire cost for a plurality of edges in a mining road network, identifying least-cost paths between each of a plurality of nodes on the mining road network using the tire cost for each of the plurality of edges, the nodes including a loading area and a dumping area for a plurality of haul trucks, accessing a distributed objects database to identify constraints for the nodes on the mining road network, determining a production plan using the constraints for the nodes on the mining road network by maximizing a function of the form αf′(x)-βg′(x), where f′(x) is a normalized measure of productivity, g′(x) is a normalized measure of impact on tire conditioning, and α and β, are nonnegative constants with α+β=1, subject to constraints on resource capacities and production requirements, with the material flow rates between each of the nodes on the mining road network specifying the production plan, determining a task assignment for each of the plurality of haul trucks using the production plan as guide, and transmitting the task assignment for each of the plurality of haul trucks.
