Maintenance Class

Description:	maintenance event
Detail:

See also Maintenance Property Reference for a detailed list of properties for this class of object.

The Maintenance class of objects provides function for performing value-based reliability studies. Maintenance events can be optimized on Generator, Line and Gas objects including Gas Pipeline, Gas Plant, Gas Field, Gas Storage and Gas Transport.

Key property

The key property for the Maintenance class is Duration. Use this property to Scenario in/out the Maintenance objects from your simulation.

Outage elements

The Maintenance event can involve one or more:

• Generators
• Lines
• Gas Pipelines
• Gas Plants
• Gas Fields
• Gas Storages
• Gas Transports

By default the event causes a total outage of the element(s). You can create partial outages with properties such as Generators Outage Rating, Lines Outage Max Rating and GasPipelines Outage Max Flow.

Resources

Each event can consume resources defined on the properties Cost, Crew and Equipment and Constraint objects can involve these terms. These properties are multi-band allowing you to record different tranches of cost on separate bands.

Constraints

The event can be restricted such that it occurs only in a defined Window of time.

An event can have one or more Prerequisites i.e. maintenance events that must precede the event.

Optimization

The optimization can be deterministic or stochastic with the Non-anticipativity property controlling which events are first-stage decisions.
