Abstract

Embodiments of the invention relate to a method for providing performance driven municipal asset needs and sustainability analysis. The method includes calculating asset health scores for a plurality of assets in an infrastructure. The asset health scores change as a function of time. The method also includes identifying prescription options for the assets. The identifying is based on the asset health scores. The prescription options include cost, value, and time for execution. A multi-objective optimization is applied based on the asset health scores and prescription options to identify at least a subset of the prescription options that may be implemented within a provided budget to maintain a sustainability threshold for an overall infrastructure health score.

Claims

1. A computer-implemented method for asset management, the method comprising:

calculating asset health scores for a plurality of assets in an infrastructure, wherein the asset health scores change as a function of time;

identifying prescription options for the assets, the identifying based on the asset health scores, and the prescription options comprising cost, value and time for execution; and

applying multi-objective optimization based on the asset health scores and prescription options to identify at least a subset of the prescription options that may be implemented within a provided budget to maintain a sustainability threshold for an overall infrastructure health score.

2. The computer-implemented method of claim 1, wherein calculating the asset health scores is based on business drivers associated with the assets, factors associated with the business drivers that describe conditions of the assets, and degradation predictions associated with the assets.

3. The computer-implemented method of claim 2, wherein a business driver is assigned a weight to indicate a relative importance of the business driver to an asset health score of an asset, and the weight is input to calculating the asset health scores.

4. The computer-implemented method of claim 2, wherein a factor is assigned a weight to indicate a relative importance of the factor to a business driver, and the weight is input to calculating the asset health scores.

5. The computer-implemented method of claim 1, wherein an output of the applying includes at least one of a predicted change in an expected remaining life of an asset and a predicted change in a quality service level of an asset.

6. The computer-implemented method of claim 1, wherein an output of the applying includes at least one of a predicted qualitative improvement and a predicted quantitative improvement of an asset.

7. The computer-implemented method of claim 1, wherein the multi-objective optimization is further based on a selected point in time and the overall infrastructure health score corresponds to the selected point in time.

8. The computer-implemented method of claim 1, wherein:

the infrastructure is a city infrastructure;

the assets include assets characterized as under ground assets and above ground assets; and

the assets include assets characterized as linear assets and point assets.
