G-DEVS/HLA Environment for Distributed Simulations of Workflows

Abstract

In this paper, we present a Workflow environment allowing distributed simulation based on DEVS / G-DEVS formalisms. A description language for Workflow processes and an automatic transformation of a Workflow into a G-DEVS model have been defined. Then, we introduce a new distributed Workflow Reference Model with HLA-compliant Workflow components. We detail the HLA objects shared between Workflow federates and we present the publishing/subscribing status of each of these federates. Finally, we illustrate the use of this distributed environment with an example of a Microelectronic production Workflow.

Sustaining interoperability of networked liquid-sensing enterprises: A complex systems perspective

“…(xi) Immersive Simulation, which is a promising trend where the system and the resources can be solicited for behavior validation. Simulation can be used to anticipate the need to update the least efficient (or deficient) parts of the system, browsing a base of potential solutions that can improve the tested system performance (Angulo, 2013;Zacharewicz, Frydman, & Giambiasi, 2008).…”

Time-based orchestration of workflow, interoperability with G-Devs/Hla

“…Zacharewicz et al [4] proposed in, an environment, named DEVS Model Editor (LSIS DME), to create G-DEVS models that are HLA compliant and simulating them in a distributed fashion. In LSIS DME, a G-DEVS model structure can be split into federate component models in order to build a HLA federation (i.e., a distributed G-DEVS coupled model).…”

“…Also, [25,26] have used G-DEVS models and HLA RTI to simulate the behaviour of several components by mixing HLA and web service calls. The distributed simulation principle of [26] was based on the original pessimistic algorithm described in [6], adding more recent advances on lookahead described in [4]. These set-ups, with RTI as mediator of all messages exchanged, can be interesting from the interoperability point of view but they can cause overheads and slow down the communication as discussed in [27].…”

“…The workflow steps are based on observing a number of steps that were originally manually enchained then formalizing them to be computer assisted. The research on the WF initiated by the Workflow Management Coalition [1,2] and used for instance in [4] was a premise to current WF modelling (e.g., with Business Process Model and Notation (BPMN) [5]). It has permitted for instance the development of Build Time models used for setting Enterprise Resource Planning (ERP) systems.…”
