Prognostic condition assessment decision aid
First Claim
1. A computer-implemented method to manage utilization of a fleet of vehicles, comprising:
- receiving, via a computing device, data from the fleet of vehicles for historical missions and maintenance activity and at least one of hypothetical operational data and hypothetical maintenance data;
determining future mission and maintenance requirements for the fleet of vehicles using the historical missions and maintenance activity and the at least one of hypothetical operational data and hypothetical maintenance data;
processing the received data and the requirements to provide an operational allocation of the fleet of vehicles;
modifying, via the computing device, the operational allocation of the fleet of vehicles by changing at least one decision of the mission or the maintenance requirements of the operational allocation, the at least one decision selected from fault forwarding, fix or fly decision, and condition-based maintenance, or a combination thereof, the modified operational allocation satisfying at least one of reducing operational costs or increasing availability of the vehicles in the fleet of vehicles;
generating, via the computing device, a schedule for the modified operational allocation of the fleet of vehicles to implement the at least one decision of the mission or maintenance requirements; and
generating an output which presents an operational availability sensitivity analysis of fleet availability to manpower consumption for a baseline fleet and an upgraded fleet, wherein the operational availability sensitivity analysis charts fleet availability in response to a reduction in maintenance manpower from a full maintenance schedule to a maintenance schedule which results in a reduction in fleet availability.

Abstract
Methods and systems for prognostic condition assessment decision aid of a fleet of vehicles are disclosed. In one embodiment, a method includes providing a schedule of missions and maintenance of a fleet of vehicles, comprising receiving data from the fleet of vehicles for missions and maintenance activity, determining mission and maintenance requirements, processing the received data and requirements to provide an operational allocation of the fleet of vehicles, determining an alternative allocation of the operational allocation of the fleet of vehicles, the alternative allocation satisfying at least one operational objective for the fleet of vehicles, and generating a schedule for the alternative allocation of the fleet of vehicles.

13. One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed on one or more processors, perform acts comprising:
-
receiving data for historical activity and future requirements for a fleet of vehicles for missions and maintenance and at least one of hypothetical operational data and hypothetical maintenance data; generating at least one prognostic indicator from the received data for missions and maintenance of the fleet of vehicles and the at least one of hypothetical operational data and hypothetical maintenance data; determining at least one decision criteria for the future requirements that impacts the prognostic indicator, the at least one decision criteria selected from at least one of fault forwarding, fix or fly decision, or condition-based maintenance; determining an allocation of the fleet of vehicles based on the received data, the at least one prognostic indicator, and the at least one decision criteria to at least one of increase fleet reliability and reduce operational costs; and generating a schedule for the allocation of the fleet of vehicles that implements the at least one decision criteria; and generating an output which presents an operational availability sensitivity analysis of fleet availability to manpower consumption for a baseline fleet and an upgraded fleet, wherein the operational availability sensitivity analysis charts fleet availability in response to a reduction in maintenance manpower from a full maintenance schedule to a maintenance schedule which results in a severe reduction in fleet availability. - View Dependent Claims (14, 15, 16)

17. A computer-based system to manage utilization of a fleet of vehicles, comprising:
-
an input component configured to receive data for historical activity and future requirements from the fleet of vehicles for missions and maintenance and at least one of hypothetical operational data and hypothetical maintenance data; a processor component configured to generate a prognostic and system heath management indicator from the received data for missions and maintenance of the fleet of vehicles and the at least one of hypothetical operational data and hypothetical maintenance data; generate decision criteria for the future requirements that impacts the prognostic indicator, the decision criteria including at least one of condition-based maintenance and fix or fly decisions; provide a mission and maintenance allocation of the fleet of vehicles utilizing the received data, the prognostic indicators, and the decision critera to at least one of increase fleet reliability and reduce operational costs; and generate a schedule for the mission and maintenance allocation of the fleet of vehicles; and generate an output which presents an operational availability sensitivity analysis of fleet availability to manpower consumption for a baseline fleet and an upgraded fleet, wherein the operational availability sensitivity analysis charts fleet availability in response to a reduction in maintenance manpower from a full maintenance schedule to a maintenance schedule which results in a severe reduction in fleet availability. - View Dependent Claims (18, 19, 20, 21)
