A flexible, modular approach to integrated space exploration campaign logistics modeling, simulation, and analysis

object classes are displayed as boxes with an italicized font. Abstract object classes primarily provide a design interface to group concrete implementations in a way that is extensible to future development. Concrete objects classes are displayed as boxes with a standard font. Concrete object classes may implement an abstract class or may provide other functionality. Subclass relationships, indicated with a white triangle, identify specialized object classes of the superclass that can be substituted for any generic super-class application. Aggregation relationships, indicated with a white diamond, identify access to related object classes that may change over the course of the object lifetime. This differs from composition relationships, indicated with a black diamond, which identify permanent ownership of related object classes. In the example illustrated in Figure 72, the Vehicle abstract object class serves as an interface to the concrete object subclasses Car and Airplane. The Car object class is a composition of Engine using the assumption that a car‟s engine does not change and it is an aggregation of Passenger. Figure 72: Example object model diagram. The Vehicle interface has two subclass objects, Car and Airplane. A car is comprised of an engine object and aggregates Passenger objects.
