maximizes aggregate resource production at the wellsites within constraints of the wellsite inputs and the supply site inputs.
4 . The method of claim 1 wherein the wellsite inputs are stored in and provided by one or more wellsite module communication devices that are physically separate from one or more supply site module communication devices in which the supply site inputs are stored or input and from which the supply site inputs are provided.
5 . The method of claim 4 wherein the current detailed plan is generated via at least one planning center module communication device, such that the actions and corresponding times are itemized for being stewarded and/or accomplished by a planning center user via the at least one planning center module communication device.
6 . The method of claim 5 wherein each planning center module communication device is physically separate from the wellsites and the supply sites.
7 . The method of claim 1 wherein the wellsite inputs and supply site inputs comprise historical information about operation, goals, and logistics involving the wellsites and the supply sites, and wherein generating the current detailed plan includes dynamic prioritization of certain actions to attain certain goals without allocation of weighting amongst inputs being entered by a user.
8 . The method of claim 1 wherein the actions comprise a schedule of dispatch actions and corresponding times at which a specific transportation equipment is to be sent to a specific wellsite or supply site to unload or load, respectively, a specific one of the materials.
9 . The method of claim 1 wherein the actions comprises a schedule of dispatch actions and corresponding times at which a specific transportation equipment is to be held at a specific wellsite or supply site or to be returned to a neutral site, awaiting instruction to load, unload, or move to another wellsite, supply site, or neutral site.
