a b s t r a c tEnterprises information systems (EIS) take benefits of latest advanced of web services and Internet of things to improve information retrieving and gathering for decision making. Furthermore, EIS should permit a more comprehensive information routing in the company within an electronic workflow in order to save time, cost and to reduce production impact on the environment. Such software has to interact frequently with real world data acquired by different sensors. Nevertheless this combination of software and hardware devices frequently faces interoperability problems. Also, testing and validating the EIS is not trivial without testing in real condition that can lead to deploy the large system. Authors assumed that testing and validating part of the system behaviour can be anticipated progressively by simulation, permitting then more progressive and confident system integration. This paper proposes to introduce a new workflow demonstration platform to combine simulation world with real world interacting with sensor, human interfacing and web service calls. In detail, this paper proposes to combine the Taverna Workflow tool, which handles and triggers web services call proposed by a platform server, to other software components. This combination has revealed one drawback of major workflows orchestrators; they do not provide time management facilities to handle synchronization during parallel execution of interdependent workflows. To overcome that limitation a clock ordering solution has been added by reusing G-DEVS/HLA to synchronize workflows running in parallel. The imbrications of G-DEVS M&S with Taverna workflow is now operating thanks to HLA. This work is validated by demonstrating the interoperability and the complementarity of these approaches on a logistic platform study case.

“…The collected data/information are central in the validation and verification of the models, as they relate conceptual and formal model to the system to be modeled and analyzed by simulation. These experiments comprise again many different steps, require considerable time, and also deserve some workflow support -however due to their rather fixed nature the degree of required flexibility is different and thus also the workflow approach best pursued, see e.g., [27]. While the simulation experiments are running, new information can be collected.…”

Developing a model for simulation is an art and a science. The question is how this process can be suitably supported. Integrating workflows into simulation systems promises user guidance, documentation and reproducibility of this process. However, the highly interactive, partly concurrent, partly optional nature of the modeling process challenges traditional activity-based workflow approaches. This is intensified by its multiple inter-dependencies and the need for an easy extension. We will illuminate this based on a modeling example from cell biology. To support the required flexibility, we propose an artifact-based workflow approach instead. Conceptual model, formal model and different data and information sources are specified declaratively as artifacts. The life cycle of an artifact is defined by stages, guards, milestones, and sentries, following the Guard-Stages-Milestone (GSM) approach. It is shown that the declarative specification provides a better fit for the process of developing a model.

“…There are a number of reports on systems with similar objectives in the literature outside the MD simulation domain --e.g. the SAFE framework for automating network simulations (Perrone, 2012), or WorMS (Rybacki, 2011), a workflow framework for modelling and simulation in general --the most important distinguishing characteristic of our approach is that it does not define a language in which simulations are defined. Instead, it provides a means for the domain expert to create such languages.…”

Abstract:Molecular dynamics simulators are indispensable tools in the arsenal of chemical engineers and material scientists. However, they are often difficult to use and require programming skills as well as deep knowledge of both the given scientific domain and the simulation software itself. In this paper, we describe a metaprogramming approach where simulator experts can create a library of simulation components and templates of frequently used simulations. Domain experts, in turn, can build and customize their own simulations and the required input for the various supported simulators is automatically synthesized. The web-based environment also supports setting up a suite of simulation jobs, for example, to carry out automated parameter optimization, via a visual programming environment. The entire simulation setupincluding the various parameters, the version of tools utilized and the results -is stored in a database to support searching and browsing of existing simulation outputs and facilitating the reproducibility of scientific results.
