| + | |||
| + | Members of the Model Lifecycle Management Activity Team suggest that the OMG SysML Specification team consider the inclusion of the concepts of bounded temporality--or what innovative PLM vendors call "effectivity" into the elements of SysML's structural, behavioral, and relational elements. All concepts (here, both abstract and reified) except for axiomatic Truths exhibit temporality. That is, their spatial extent, their behavior, or their relationships hold for particular durations in Time. However, current modeling notations and practices assume that every structural, behavioral, or relational claim either always does not exist or always does exist. The inability to explicitly represent temporality or effectivity in model elements leads architects and systems engineers into awkward complexity as they attempt to communicate that particular claims within their models hold for one context yet don't, may not, or may be qualitatively different in other contexts. | ||
