A computer based system automatically gathers, analyzes, and delivers information relating to the procurement and utilization of a plurality of such assets, such as a fleet of industrial equipment, so as to maximize productivity and to reduce operating costs and administrative burdens. Each of the assets is preferably provided with a data acquisition device for sensing and storing one or more operating characteristics associated therewith. That information can be transmitted through space to a receiver connected to a local controller for storing such information and for transmitting such information to a remote analysis system. The remote analysis system automatically updates individual records associated with each of the assets with the information received. In response to such information, the remote analysis system automatically analyzes the newly provided information and schedules maintenance as required. Information associated with the maintenance is also recorded electronically to maximize efficiency, provide historical trends, automate billing, and control inventory levels.

1. A maintenance system involving Wthe gathering and analyzing of data relating to an asset comprising:a local controller located at a first location for acquiring data that is representative of an operational status of the asset; an analysis controller located at a second location that is responsive to said acquired data from said local controller for generating an analysis of said acquired data; a database of historical information representing at least prior maintenance of the asset and a class of assets associated with the asset, said analysis including comparing said acquired data to said historical information to determine if proposed maintenance is required; an electronic communications network connected between said local controller and said analysis controller and permitting transmission of said acquired data from said local controller to said analysis controller; a work order generated based on said analysis representing instructions for maintaining the asset; and an inventory comparison sub-system, said sub-system permitting a comparison of any part removed with existing inventory for a specific inventory location to automatically order a replacement part for the inventory location upon determining that the number of parts in a particular inventory falls below a pre-determined threshold, and wherein said threshold is actively calculated in part based on said historical information and selectively changes as said historical information changes. 2. A maintenance system as recited in claim 1, further comprising an approval process wherein a responsible party charged with paying for maintaining the asset reviews said analysis, and wherein if said responsible party denies an approval, an owning party that owns the asset reviews said analysis and selectively overrides the denial of the approval.3. A maintenance system as recited in claim 1, wherein said work order includes asset identification information, said asset identification information comprising at least a subset of an operating characteristic, results of said analysis, operator of record, and asset location.4. A maintenance system as recited in claim 3, wherein said work order is transmitted electronically to a handheld device, said handheld device in selective two-way communication with said database.5. A maintenance system as recited in claim 4, wherein asset part inventory is electronically accessible to said handheld device.6. A maintenance system as recited in claim 4, wherein said handheld device updates said historical information once maintenance of the asset is complete, and an invoice is electronically generated based on said update to said historical information.7. A maintenance system as recited in claim 6, wherein said update of said historical information includes labor information, an identification of any part required to effect maintenance, and the inventory location from which the part was removed.8. A maintenance system as recited in claim 1, wherein said data representing said operational status comprises at least one of a fault code, an operator checklist generated response, and an operational characteristic of the asset.9. A method for maintaining an asset comprising the steps of:activating a local controller located at a first location; acquiring data at a first location that is representative of an operational status of the asset, which is communicated from the asset to said local controller; transmitting said acquired data at pre-determined intervals from said local controller to an analysis controller located at a second location using an electronic communications network connected between said local controller and said analysis controller; analyzing said acquired data, wherein said analysis step comprises the sub-step of comparing said acquired data to a database of historical information representing at least prior maintenance of the asset and a class of assets associated with the asset to determine if proposed maintenance is required; generating a work order based on said analysis representing instructions for maintaining the asset; carrying out said work order to maintain the asset; identifying any parts used in said cairyin, step; determining an inventory location from which said part was pulled; comparing an inventory level at said inventory location to a pre-determ-ined threshold; and automatically ordering a replacement part for said inventory location upon determining that the number of parts in a particular inventory fall below said pre-determined threshold, and wherein said threshold is actively calculated in part based on said historical information and selectively changes as said historical information changes. 10. A method as recited in claim 9, wherein said analysis step comprises the further sub-steps of:instituting an approval process of said proposed maintenance; a responsible party disapproving said proposed maintenance; updating said comparing step based on said disapproving; and creating a knowledgebase minimizing said disapproving over a class of assets corresponding to the asset using said instituting, said disapproving and updating steps. 11. A method as recited in claim 9, further comprising the steps of:electronically transmitting said work order to maintenance personnel; electronically communicating results of maintenance to provide an update of said historical information including labor information and any part required to effect maintenance; and electronically generating an invoice. 12. A maintenance system involving the gathering and analyzing of data relating to an asset comprising:a local controller located at a first location for acquiring data that is representative of an operational status of the asset; an analysis controller located at a second location that is responsive to said acquired data from said local controller for generating an analysis of said acquired data; a database of historical information representing at least prior maintenance of the asset and a class of assets associated with the asset, said analysis including comparing said acquired data to said historical information to determine if proposed maintenance is required; an electronic communications network connected between said local controller and said analysis controller and permitting transmission of said acquired data from said local controller to said analysis controller; an approval process wherein a responsible party reviews said analysis to confirm that a proposed maintenance is appropriate; a work order generated based on said analysis of said proposed maintenance and said approval process, representing instructions for maintaining the asset, wherein said work order is transmitted electronically to a handheld device, said handheld device providing an update to said historical information once maintenance is complete, said update including labor information and an identification of any part required to effect maintenance; an invoice generated based on said update to said historical information; and wherein said update includes the inventory location from which the part was removed and further comprising an inventory comparison sub-system, said sub-system permitting a comparison of any part removed with existing inventory for a specific inventory location to automatically order a replacement part for the inventory location upon determining that the number of parts in a particular inventory falls below a pre-determined threshold, and wherein said threshold is actively calculated in part based on said historical information and selectively changes as said historical information changes.
