Abstract

A network spares audit, optimization, and maintenance system and method, including: an application running on a processor of one of (1) a network management system of a network and (2) a logistics management tool external to the network and in communication with the network management system of the network, the application including: a mapping algorithm executed by the application and operable for mapping network elements of one or more networks to spares depots; and a probabilistic risk analysis algorithm executed by the application and operable for utilizing statistical analysis to determine how many and what types of spares are stocked at each spares depot based on inputted conditions; wherein operation and output of the application is dynamically updated based on network configuration information automatically received from the network management system of the network.

Claims (34)

1. A network spares audit, optimization, and maintenance system, comprising:

a processor configured to execute an application, the processor associated with one of (1) a network management system of a network and (2) a logistics management tool external to the network and in communication with the network management system of the network, wherein the network management system performs network discovery and provides the application with live network data related to equipment present at each site in the network in real time, the application comprising:

a probabilistic risk analysis algorithm executed by the application and operable to utilize statistical analysis to determine how many and what types of spares are required at each of one or more spares depots based on inputted conditions, the live network data, and network configuration information; and

a mapping algorithm operable to map the equipment of the network to the one or more spares depots, and wherein the equipment is mapped to the one or more spares depots by first mapping the equipment to sites and then mapping the sites to the one or more spares depots;

wherein the application is configured to provide one or more of a notification of new spares requirements and an assessment of risks based on newly added equipment detected in the live network data.

2. The network spares audit, optimization, and maintenance system of claim 1 , wherein the application compares actual spares levels in the spares depots to required spares levels in the spares depots and flags any discrepancies prior to a fault occurring.

3. The network spares audit, optimization, and maintenance system of claim 1 , wherein the inputted conditions comprise one or more of contractual obligations, customer specified sparing algorithms, risks, risk limits, costs, cost limits, Mean Time to Breakdown data, Mean Time to Replace data, fault data, repair data, service interruption data, and network growth predictions.

4. The network spares audit, optimization, and maintenance system of claim 1 , wherein the application monitors the one or more networks for configuration changes and, if detected, updates its statistical analysis.

5. The network spares audit, optimization, and maintenance system of claim 1 , wherein the equipment of the one or more networks is each mapped to one or more spares depots.

6. The network spares audit, optimization, and maintenance system of claim 1 , wherein the mapping algorithm is operable to highlight any of the equipment that is not mapped to a spares depot.

7. The network spares audit, optimization, and maintenance system of claim 1 , wherein the probabilistic risk analysis algorithm is operable to indicate a confidence interval within which a risk evaluation falls based on a standard deviation of one or more of Mean Time to Breakdown data and Mean Time to Replace data.

8. A network spares audit, optimization, and maintenance method, comprising:

executing an application on a processor associated with one of (1) a network management system of a network and (2) a logistics management tool external to the network and in communication with the network management system of the network, wherein the network management system performs network discovery and provides the application with live network data related to equipment present at each site in the network in real time, the application comprising:

a probabilistic risk analysis algorithm executed by the application and operable to utilize statistical analysis to determine how many and what types of spares are required at each of one or more spares depots based on inputted conditions, the live network data, and network configuration information; and

a mapping algorithm operable to map the equipment of the network to the one or more spares depots, and wherein the equipment is mapped to the one or more spares depots by first mapping the equipment to sites and then mapping the sites to the one or more spares depots;

wherein the application is configured to provide one or more of a notification of new spares requirements and an assessment of risks based on newly added equipment detected in the live network data.

9. The network spares audit, optimization, and maintenance method of claim 8 , wherein the application compares actual spares levels in the spares depots to required spares levels in the spares depots and flags any discrepancies prior to a fault occurring.

10. The network spares audit, optimization, and maintenance method of claim 8 , wherein the inputted conditions comprise one or more of contractual obligations, customer specified sparing algorithms, risks, risk limits, costs, cost limits, Mean Time to Breakdown data, Mean Time to Replace data, fault data, repair data, service interruption data, and network growth predictions.

11. The network spares audit, optimization, and maintenance method of claim 8 , wherein the application monitors the one or more networks for configuration changes and, if detected, updates its statistical analysis.

12. The network spares audit, optimization, and maintenance method of claim 8 , wherein the equipment of the one or more networks is each mapped to one or more spares depots.

13. The network spares audit, optimization, and maintenance method of claim 8 , wherein the mapping algorithm is operable to highlight any of the equipment that is not mapped to a spares depot.

14. The network spares audit, optimization, and maintenance method of claim 8 , wherein the probabilistic risk analysis algorithm is operable to indicate a confidence interval within which a risk evaluation falls based on a standard deviation of one or more of Mean Time to Breakdown data and Mean Time to Replace data.

15. A network management system of a network, comprising:

a processor executing a network spares audit, optimization, and maintenance application, the network spares audit, optimization, and maintenance application comprising:

a probabilistic risk analysis algorithm executed by the application and operable to utilize statistical analysis to determine how many and what types of spares are required at each of one or more spares depots based on inputted conditions; and

a mapping algorithm operable to map equipment of the network to the one or more spares depots, and wherein the equipment of the network is mapped to the one or more spares depots by first mapping the equipment to sites and then mapping the sites to the one or more spares depots;

wherein the network management system performs network discovery and provides the application with live network data related to equipment present at each site in the network in real time;
