Example text

In UML semantics, the object flow weight represents the minimum number of tokens that must traverse the edge at the same time. We assume that the weight of an object flow represents the total number of objects required for an action if they are input objects, or the total number of objects created in an action if they are output objects. An unlimited weight (∗) is used if the number of input/output objects is not a constant. Figure 2 depicts the sample source business model containing four simplified DADs representing the four members-related business processes in (university) library.
