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.
