absel-1905	Fuhs, F. Paul	Event-Extended Entity-Relationship Diagrams for Understanding Simulation Model Structure and Function	1988	5	.pdf	application/pdf	3744	150	38	This paper demonstrates the need for such a communication method for designers and users, It briefly introduces some of the concepts in E-R modeling and shows the similarity of model constricts between simulation models and database models as the basis for beginning with the E-R diagram, It then sets down the semantic constructs required to enhance E-R diagrams to fore Event-Extended Entity-relationship diagrams. One apparent difference between simulation models and database models is that the “event’ construct and the trigger” construct that sequences events are explicit in many simulation model, yet are not explicit in E-R diagrams.	cache/absel-1905.pdf	txt/absel-1905.txt
