DEVS (Discrete Event System Specification) is a modular and hierarchical formalism for modeling and analyzing general systems that can be discrete event, continuous state and hybrid continuous state systems.
Most modelers who are familiar with DEVS see the view point of DEVS as a modeling formalism forgetting the DEVS simulation protocol.
The clarification needed here , is if we recollect and readjust our mind set to DEVS including the Simulation Protocol are we scientifically right to presume DEVS is a domain as well as a formalism.

Dear Mohamed Sir,
I got the papers you sent . i went through them and i realized that there was just a mention of DEVS as a domain. No section or subsection went into the detail of why we should be convinced scientifically that DEVS is a domain.
if we consider this three ; Experimental Framework, Model and Simulator , is the validation looking concrete that implies DEVS as a domain? . Modeling and Simulation community already agreed that DEVS is a formalism.
Maybe i did not get the message am supposed to from the papers.
Thank you for your kind response. Hoping to hear from you
DEVS is discrete event systems modeling formalism. To justify it we must look to the roots and then we will see that this term is coming out of simulation. Therefore understandings exactly of this part researchers are major. Protocol could be part of specification. DEVS cannot be used for continuos systems specification. There are other methods.
