In addition, OPM manages system complexity through three refinement/abstraction mechanisms:

  • Unfolding/folding, which is used for refining/abstracting the structural hierarchy of a thing;
  • In-zooming/out-zooming,
  • which exposes/hides the inner details of a thing within its frame; and state expressing/suppressing, which exposes/hides the states of an object [66],[67].

Using these mechanisms, OPM enables specifying a system to any desired level of detail without losing legibility and comprehension of the resulting specification.
此外，OPM通过三种细化/抽象机制来管理系统复杂性:

  • 展开/折叠，用于细化/抽象事物的结构层次;
  • 放大缩小，即在画面中暴露/隐藏事物的内部细节;
  • 状态表达/抑制，它暴露/隐藏对象的状态[66]。

通过使用这些机制，OPM可以将系统指定为所需的任何细节级别，而不会失去对结果规范的可读性和理解。
