For such complex and composite systems as analogue and digital systems, electronic and mechanical systems, the Ptolemy II attain purposes with heterogeneously hierarchical ideology, in other words, actors and model of computation at the same level stand for a behavior of the system, and these components at this level can be converted into a composite actor that stands for another behavior of the system under the control of different models of computation at upper level with other actors. In this way, the system may be structured hierarchically.

对于复杂的混合系统，如模拟与数字系统，电子与机械系统，Ptolemy II采用层次异构的思想实现，即同层的角色和计算模型表示系统的一种行为，而这一层组件又可转变为一个复合角色，在上一层与其它角色在不同的计算模型控制下表示系统的另一种行为，从而实现系统的层次构架。
