"The Event Model" for Situation Awareness

The Event Model (TEM) is a novel computation-independent model targeted at helping non-programmers to define and manage the logic of event-driven applications. The model design is based on a collection of building blocks that comprise a set of diagrams and normalized tables to define the event business logic of an application, a set of principles that define the set of assertions that a correct model should satisfy, and a glossary to express all the business concepts. The validity of the TEM model created is checked and guaranteed through a related set of integrity principles, and automatically translated to execution by the code generator. In this paper we concentrate on the model itself. The concepts and facilities of the model are demonstrated through an example taken from the Cold Chain Management (CCM) domain. Preliminary tests in the scope of transport and logistics indicate that the tables and diagrams in TEM are well accepted and embraced by non-technical people, who stress the ease and friendly manner of defining the event logic as the main benefit of TEM.
