MSET Industrial Early Warning System

System breakdowns in modern industrial environments can result in millions of dollars in lost time and productivity, and even the loss of life and property. In the utilities industry — where the continuous operation of coolant pumps is essential — the breakdown of a single pump can result in a loss of as...

Using SysML to Model Layered System Interfaces

To produce accurate system architecture descriptions, it is essential to be able to describe interfaces between system elements at different levels of abstraction and from different perspectives at the same time. For example, the connection from system A to system B may be viewed at a high level as...
