System Reliability: Workflow

Add a Subsystem

Add a subsystem to present a new diagram palette. A diagram does not require subsystems, but can contain as many subsystems as you require.

Add an Asset to the Subsystem

Add an Asset diagram element to the subsystem to express an entity that is essential to system function (e.g., a pumping system would likely have an asset of Pump).

Import a Growth Analysis

Import a Growth Analysis by searching and selecting a growth analysis from the generated list. The imported growth analysis will be expressed in the diagram as an Asset, where the asset has a failure rate that is based on the growth analysis.

Import a Reliability Distribution

Import a Reliability Distribution by searching and selecting a reliability distribution from the generated list. The imported reliability distribution will be expressed in the diagram as an Asset where the asset has a failure rate (TTF) and repair rate (TTR) that is based on the reliability distribution.

Import an Asset

Import an Asset by searching and selecting an asset from the hierarchy. The imported asset will be expressed in the diagram as an Asset where the failure rates of the asset are based on previous reliability distributions or growth analyses. Additionally, this will create a relationship between the analysis and the asset

Build K Out of N Subsystem

Build K out of N Subsystems, where K is the number of assets required in order to meet the system requirements (e.g., a pumping system could have three pumps in parallel, where each pump has a production contribution of 50% and the system requirement is met by having any two of the three pumps available).

Simulate Partial Production Loss

Simulate partial production loss using a model of parallel assets where one asset does not imply total failure of a system, but instead reduces the system capacity.

Build a Subsystem with a Buffer

Build a subsystem with a buffer, which can be used to simulate time delays.

Build a Backup Subsystem

Build a backup subsystem by using a model where K number of assets are required to be available to meet the system requirements.

For example, a pumping system could have three pumps in parallel, where each pump has a production contribution of 50% and the system requirement is met by having any two of the three pumps available. In this case, one of the assets will have the initial setting of Off and the other two assets will have initial settings of On. Through the application of switches and sensors, the system does not experience a failure because the backup asset will be turned On when a failure occurs in either of the other two assets

Edit Distribution (TTF)

Edit the TTF Distribution to define the rate at which failures occur to the asset.

Edit Distribution (TTR)

Edit the TTR Distribution to define the rate at which repairs occur to the asset.

Add Resource Usage (Planned)

Add a Planned Resource Usage to define usages of resources and their associated costs. Associated costs include, but are not limited to, Parts, Personnel, Fuel, and Equipment Rental that are incurred on a planned basis.

Add Resource Usage (Unplanned)

Add an Unplanned Resource Usage to define usages of resources and their associated costs. Associated costs include, but are not limited to, Parts, Personnel, Fuel, and Equipment Rental that are incurred on an unplanned basis. In many instances, unplanned resource usage incurs a larger cost to the organization that planned usages of the same resource.

Reset Related Risks

Reset Related Risks to reset specific failures based on the execution of an Action.

For example a pumping system could have three failure modes, such as bearing failure, seal failure, and impeller failure. If a rebuild Action took place, then this could effectively reset the risk of each of these failure modes.

Import Reliability Distribution Values

Import Reliability Distribution Values by searching and selecting a reliability distribution from the list. The failure rates of the distribution will be associated with the given risk

Import Reliability Growth Values

Import Reliability Growth Values by searching and selecting a growth analysis from the list. The failure rates of the growth analysis will be associated with the given risk.

Add Resource Usage

Add Resource Usage to define usages of resources and their associated costs. Associated costs include, but are not limited to, Parts, Personnel, Fuel, and Equipment Rental that are incurred as part of the Action.

Mitigate Risks

Mitigate risks by selecting which of the risks the action will mitigate within the context of an Action.
