摘要： Methods and apparatus are provided for determining a lowest total cost maintenance plan. The method comprises receiving a sequence of maintenance actions in an order of a waiting time for each maintenance action, wherein one of the maintenance actions is likely to repair the failure mode. Each maintenance action has an associated cost equal to a waiting time cost, an execution time cost and a material cost, wherein the waiting time of each maintenance action is the time required to requisition and receive material required to perform the maintenance action. The method also constructs a maintenance plan comprising a primary requisition and a secondary requisition by assigning each of the sequence of maintenance actions to one of the primary and secondary requisition.

摘要： Methods and apparatus are provided for selecting a maintenance plan such that the cost of the maintenance plan is the lowest or near the lowest. The method comprises receiving a set of maintenance actions, wherein one of the repair actions is likely to repair the failure mode. The set of maintenance actions is sequenced in the increasing order of their waiting times. Each maintenance action has an associated cost equal to a waiting time cost, an execution time cost and a material cost, wherein the waiting time of each maintenance action is the time required to requisition and receive material required to perform the maintenance action. The method also constructs a maintenance plan comprising a first requisition and a second requisition by assigning each of the sequence of maintenance actions to one of the first or the second requisition.

摘要： A method of detecting and diagnosing system faults, includes detecting the noisy status of a monitor during operations and incorporating a quantified monitor uncertainty level to support fault isolation reasoning. A sequential probability ratio test is used to statistically test the noisy status of a monitor and Shannon's entropy theory is used to quantify the uncertainty levels of the monitor to support the use of the monitor values in fault isolation.

摘要： Methods, systems and computing devices are provided for using a completed corrective action as evidence of a fault. The methods, systems and computing devices receive equipment status evidence and determine an equipment fault based on the equipment status evidence. The methods, systems and computing devices also create and rank a list of potential failure modes based at least in part on the determined equipment fault, recommend a corrective action to correct the equipment fault based at least in part on the ranking of the potential failure modes and receiving additional equipment status evidence indicating that the recommended corrective action failed to correct the equipment fault. The methods, systems and computing devices then associate a detection probability and a false negative rate with the failed corrective action to create additional status evidence, and re-rank the list of potential failure modes for subsequent performance based on the additional status evidence.

摘要： Provided are methods and systems distributing a data message to an unknown destination device across at least one spatial boundary and at least one administrative domain boundary from an originating device. The system includes at least one distributor module that exists within each administrative domain of a network through which the data message may originate, may terminate or may traverses in route from the originating device to the unknown destination device. Each administrative domain within each of a plurality of equipment platforms has at least one distributor module. The system also includes a domain bridge spanning the at least one administrative domain boundary within an equipment platform of the plurality through which the data message traverses in route to the unknown destination device. The system operates using a network discovery service whereby an advertisement is published for a specific type of data by the unknown destination device. The advertisement is promulgated throughout the network. Each distributor module in the network acts a surrogate for the unknown destination device by accepting the data and relaying it to another surrogate until it arrives at the destination device. The system allows the data to pass through both spatial and administrative barriers automatically.

摘要： A method for improving fault classifications for failure modes in complex systems, and a software program embodying the method or a corresponding method together with a computer based aircraft diagnostic system using such software is described. The method includes: capturing an observation that is consistent with a discrepancy of the complex system; identifying a set of failure modes of the complex system that are consistent with the observation; ranking, when the set includes more than one failure mode, the failure modes according to a degree of support the observation provides for each failure mode, the degree of support including a historical component; determining additional possible observations that are consistent with any failure mode included in the set; and ranking the possible observations according to how rapidly they reduce a number of failure modes included in the set; then preferably selecting a further observation and repeating the above steps until only one failure mode remains.
