The parts.xml configuration file contains configuration for all the parts used in the simulation.

A "part" element has a unique "name" attribute. It has a required "mass" attribute that shows the mass of the individual part in kilograms. It also has the following child element:

maintenance-entity-list: This is an optional element that is a list of all entities that may require this part for periodic maintenance.

entity: This is an entity that requires this part for periodic maintenance. The "probability" attribute is required and is the percentage (0 - 100) probability that this part will be needed during a given maintenance. The "max-number" attribute is required and is the maximum number of this part needed for a given maintenance.

The following entities types are supported for maintenance:

• Vehicle: Any vehicle.


• Rover: A pressurized, long-range, all-terrain, ground vehicle that carries a crew.


• EVA Suit: An Extra Vehicular Activity suit.


• Building: This represents any building, regardless of its functions.


• Life Support: A building with the "life-support" function (see buildings.xml).


• Living Accommodations: A building that has the "living-accommodations" function (see buildings.xml).


• Research: A building that has the "research" function (see buildings.xml).


• Communication: A building that has the "communication" function (see buildings.xml).


• EVA: A building that has the "EVA" function (see buildings.xml).


• Recreation: A building that has the "recreation" function (see buildings.xml).


• Dining: A building that has the "dining" function (see buildings.xml).


• Cooking: A building that has the "cooking" function (see buildings.xml).


• Exercise: A building that has the "exercise" function (see buildings.xml).


• Resource Processing: A building that has the "resource-processing" function (see buildings.xml).


• Storage: A building that has the "storage" function (see buildings.xml).


• Power Generation: A building that has the "power-generation" function (see buildings.xml).


• Medical Care: A building that has the "medical-care" function (see buildings.xml).


• Farming: A building that has the "farming" function (see buildings.xml).


• Ground Vehicle Maintenance: A building that has the "ground-vehicle-maintenance" function (see buildings.xml).


• Manufacture: A building that has the "manufacture" function (see buildings.xml).

Basically any building function is supported as a malfunctionable entity, only replace the hyphens in the function name with spaces. As we add more vehicles, equipment and building functions, they well be supported malfunctionable entities as well.
