System and method for resource allocation and management
First Claim
1. A method of planning resource tasking and movement where there are plural resources and plural targets and each resource has plural operational modes, comprising:
- dividing an area of interest into a grid of grid cells, each grid cell having a probability that a target is present in the grid cell and each resource having a starting point corresponding to one of the grid cells;
determining, via a computer system, an upper bound for a branch and bound objective function for each of the plural operational modes of the resources;
combining, via the computer system, the upper bounds for each operational mode into a single upper bound and determining whether to change operational modes of one or more of the resources;
pruning, via the computer system, possible resource movements by carrying out a branch and bound process with the single upper bound; and
tasking each resource in accordance with the pruned possible resource movements,wherein the operational modes for at least one resource includes a target interaction operation and wherein determining, via the computer system, the upper bound for the target interaction operation comprises;
selecting, via the computer system, a minimum of a first potential upper bound and a second potential upper bound; and
determining, via the computer system, the first potential upper bound by summing probabilities of each target being interacted with by a resource, ignoring feasibility of each resource being able to interact with more than one target.

Abstract
To improve the scheduling and tasking of resources, the present disclosure describes an improved planning system and method for the allocation and management of resources. The planning system uses a branch and bound approach of tasking resources using a heuristic to expedite arrival at a deterministic solution. For each possible functional mode of the resources, an upper bound is determined. The upper bounds are employed in an objective function for the branch and bound process to determine the functional mode in which to place the resources and to determine movement paths for the resources, all in an environment where a hostile force may attempt to destroy the resources.
