  • Patent number: 6980885
    Abstract: A computer-implemented method for routing shipments according to criticality includes accessing an initial solution to an optimization problem of routing multiple shipments to multiple locations using multiple vehicles, the initial solution including multiple loads such that each shipment is routed within exactly one load and a global cost across all loads is minimized, the initial solution being generated independent of the criticality of the shipments. Into each of one or more critical loads in a current solution, one or more non-critical shipments are inserted that are within a neighborhood of the critical load, a critical load being a load containing at least one critical shipment.
    Type: Grant
