An ARTIS model comprises eight elements:

• a configuration form, for user preferences
• a block diagram with groups and items, where each item can have capacity fluctuations and downtime events
• a network definition interface, for models that don't fit in a strict block diagram
• a list of units, with downtime modes and maintenance and inspection strategies of the items
• data interfaces, for up- and download of user input
• expressions, for parameterisation of user input
• file operations, for opening, inserting, and saving models
• runs, on any selection of the diagram
