Asset Management Systems and Methods
First Claim
1. A computer-usable medium that, when placed in operable relation to a processing device, provides software to effect a determination of an optimal asset management plan, the software comprising:
- an input module that accepts a list of assets to be managed and accepts design data and process data for each asset;
a failure module that determines probability of failure curve parameters for each degradation mode of each asset;
a simulation module that predicts asset failures to determine failure costs, and further calculates risk-weighted costs for each degradation mode of each asset, said simulation module producing a total management cost based on some combination of the failure costs and the risk-weighted costs; and
an optimization module that generates alternative management plans for evaluation by the simulation module and provides an optimal management plan for display to a user.

Abstract
Systems, methods, and software for reliability, hazard, and integrity optimization are disclosed. In at least some embodiments, the software includes an input module, a failure model module, a simulation module, and an optimization module. The input module accepts a list of assets to be managed and determines design data and process data for each asset. The failure model module determines probability of failure curve parameters for each asset degradation mode. The simulation module simulates an asset management plan to determine a total management cost that includes costs for predicted failures as well as risk-weighted costs for each degradation mode of each asset generates alternative management plans for evaluation by the simulation module and provides a selected management plan for display to a user. In each embodiment, the total management costs may account not only for direct costs, but also for safety costs, environmental costs, and business costs.

6. A plant management method that comprises:
-
identifying multiple assets in the plant; identifying multiple degradation modes; generating predictions regarding whether each asset will fail within a given time frame; estimating a failure cost that would result from each asset failure; determining risk-weighted costs over the time frame for each degradation mode of each asset; combining said risk-weighted costs to obtain a total management cost. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A reliability, hazard, and integrity optimization system that comprises:
-
a memory that stores optimization software; and one or more processors coupled to the memory to execute the software, wherein the software configures the one or more processors to; obtain a list of assets to be managed; obtain a set of degradation modes applicable to said assets; generate a prediction of whether each asset will fail within a given time frame; estimate a cost that would result from each asset failure; determine risk-weighted costs over the time frame for each degradation mode of each asset; combine said costs to obtain a total management cost; and analyze whether various actions reduce the total management cost. - View Dependent Claims (17, 18, 19, 20)
