Object Properties in Discrete Event Simulation: Attributes, Functions and non-typical Behavior

A comparison between old and new standards like GPSS, Simula67, Arena, Simio and BLUESSS is made from the point of view of additional user-defined object attributes and related functions. The scope of the applications under consideration is limited to the discrete-event, queuing and manufacturing simulation. The focus is made on the management of the object attributes and related operations, and on the way to make the simulation tool flexible enough without complicating the basic model building operations. A proposal of a new simulation tool is presented.
