In the fields of Information Systems and Software Engineering, there are widely used standards such as the Class Diagrams of the Unified Modeling Language (UML) for making information models, and the Business Process Modeling Notation (BPMN) for making process models. This tutorial presents a general Object Event Modeling (OEM) approach for Discrete Event Simulation modeling using UML class diagrams and BPMN-based process diagrams at all three levels of model-driven simulation engineering: for making conceptual domain models, for making platform-independent simulation design models, and for making platform-specific, executable simulation models. In this approach, object and event types are modeled as special categories of UML classes, random variables are modeled as a special category of UML operations constrained to comply with a specific probability distribution, and queues are modeled as ordered association ends, while event rules are modeled both as BPMN-based process diagrams and pseudo-code. In Part II, we will discuss the more advanced OEM concepts of activities and GPSS/SIMAN/Arena-style Processing Networks. Finally, in Part III, we will further extend the OEM paradigm towards agent-based modeling and simulation by adding the concepts of agents with perceptions, actions and beliefs.}, language = {en} } @misc{WagnerDrogoulFishwicketal., author = {Wagner, Gerd and Drogoul, Alexis and Fishwick, Paul and Gilbert, Nigel and Pegden, Dennis and Yilmaz, Levent}, title = {Panel Discussion: On the Unity and Diversity of Computer Simulation}, series = {Journal of Simulation Engineering}, volume = {1}, journal = {Journal of Simulation Engineering}, issn = {2569-9466}, pages = {9}, abstract = {The term Computer Simulation subsumes different simulation paradigms, languages and implementation technologies as well as many different application areas each with its own scientific communities. So, there is clearly a lot of conceptual, methodological, technological and application diversity in the area of Computer Simulation. From its start in 1967, the Winter Simulation Conference managed to get four scientific communities involved: computer scientists, electrical engineers, industrial engineers and mathematicians (operations researchers). Only later, in 2011 and 2012, an attempt was made to get environmental and social scientists involved who have been adopting the idea of "individual-based" or "agent-based" simulation. Today, two American, a European and an Asian social simulation conference have been established. How much unity exists between the scientific areas and communities represented by the Winter Simulation Conference? How much unity exists between the scientific areas and communities represented by the newer social science simulation conferences? And how much unity exists between Discrete Event Simulation and the newer forms of social science simulation?

While BPMN uses XML Schema as its default type definion language, DPMN uses UML Class Diagrams as its default (data, object and event) type definion language. As opposed to BPMN Data Objects, DPMN Data Objects instantiate an object type defined by an information model expressed in the form of a UML Class Diagram.

Because agent behavior is decoupled from physical causality, an A/OE simulator consists of an environment simulator, which simulates the physical world (the objective states of material objects), and agent simulators, which simulate the internal (subjective) states of agents and their behaviors.}, language = {en} } @inproceedings{Wagner, author = {Wagner, Gerd}, title = {Model-Based Development of JavaScript Web Applications}, series = {ICWE 2017 International Workshops, Liquid Multi-Device Software and EnWoT, practi-O-web, NLPIT, SoWeMine, Rome, Italy, June 5-8, 2017, Revised Selected Papers}, booktitle = {ICWE 2017 International Workshops, Liquid Multi-Device Software and EnWoT, practi-O-web, NLPIT, SoWeMine, Rome, Italy, June 5-8, 2017, Revised Selected Papers}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-74433-9}, doi = {10.1007/978-3-319-74433-9_25}, pages = {267 -- 268}, abstract = {This tutorial presents a model-based approach to developing plain JavaScript web applications with responsive constraint validation, enumeration attributes, uni- and bi-directional associations, and inheritance in class hierarchies.

Unlike other formalisms proposed for DES (such as Petri Nets or DEVS), our ASM semantics takes all basic DES concepts (like event types and the FEL) into consideration and allows for expressive transition system states representing the objects, properties, relations and functions of the evolving possible worlds of a simulation run. As a direct formal semantics of DES, it provides a basis for comparing, and explaining design choices in, different DES approaches. 1}, language = {en} } @inproceedings{Wagner, author = {Wagner, Gerd}, title = {Introduction to Information and Process Modeling for Simulation}, series = {Proceedings of the Winter Simulation Confrence 2017}, booktitle = {Proceedings of the Winter Simulation Confrence 2017}, editor = {Chan, Wai Kin Victor and D'Ambrogio, Andrea and Zacharewicz, Gregory and Mustafee, Navonil and Wainer, Gabriel and Page, E.}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-5386-3428-8}, pages = {520 -- 534}, abstract = {In simulation engineering, a system model mainly consists of an information model and a process model.

This tutorial presents a general approach how to use UML class diagrams and BPMN process diagrams at all three levels of model-driven simulation engineering: for making conceptual simulation models, for making platformindependent simulation design models, and for making platform-specific, executable simulation models. In our approach, object and event types are modeled as stereotyped classes and random variables are modeled as stereotyped operations constrained to comply with a specific probability distribution, while event rules/routines are modeled both as BPMN patterns and in pseudo-code.}, language = {en} } @inproceedings{DiaconescuWagner, author = {Diaconescu, Ion-Mircea and Wagner, Gerd}, title = {Modeling and Simulation of Web-of-Things Systems as Multi-Agent Systems}, series = {Proceedings of the 2015 German Conference on Multiagent System Technologies (MATES)}, booktitle = {Proceedings of the 2015 German Conference on Multiagent System Technologies (MATES)}, editor = {M{\"u}ller, J{\"o}rg P. and Kaminka, Gal and Ketter, Wolf and Wagner, Gerd}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-319-27342-6}, pages = {137 -- 153}, language = {en} } @inproceedings{Wagner, author = {Wagner, Gerd}, title = {Sim4edu.com - Web-Based Simulation for Education}, series = {Proceedings of the 2017 Winter Simulation Conference}, booktitle = {Proceedings of the 2017 Winter Simulation Conference}, editor = {Chan, Wai Kin Victor and D'Ambrogio, Andrea and Zacharewicz, Gregory and Mustafee, Navonil and Wainer, Gabriel and Page, Ernest H.}, publisher = {IEEE}, address = {Piscataway, NJ}, pages = {12}, abstract = {The sim4edu.com project website supports web-based simulation with open source technologies for open science and education.

The incorporation of Aluminum has been studied in the concentration range from 2*1014cm-3 up to 3*1020cm-3. Epitaxial layers with doping concentration NA-ND> 1019cm-3 were studied by HV-TEM and synchrotron radiation investigations. In the concentration range from 1*1019cm-3 to 3*1020 cm-3, measured by SIMS and Hall investigations, no Aluminum precipitation were detected in the grown layers. For SiC samples with an Al concentration of 1020cm-3 we have been able to detect the Al2p photoemission signal. The Al2p signal is recorded through the oxide layer (thickness of about 0.4nm), it has a main contribution at a binding energy of 73eV which corresponds to the energy typical for elemental Al0. In spectra excited with higher photon energies the sampled photoelectrons originate from deeper layers. In these data we notice an additional shoulder in the Al2p signal at around 71eV. The evidence of two contributions is attributed to the fact that Al is incorporated at different lattice sites. As the latter data represent more bulk like properties we argue that Al in the bulk SiC occupies both, substitutional lattice sites and interstitial sites while in the surface near regions Al is found only at substitutional lattice sites.}, language = {en} } @misc{SchwarzkopfDirsyteDevietal., author = {Schwarzkopf, Jutta and Dirsyte, R. and Devi, A. and Kwasniewski, A. and Schmidbauer, M. and Wagner, Gerd and Michling, Marcel and Schmeißer, Dieter and Fornari, Robert}, title = {Influence of Na on the structure of Bi4Ti3O12 films deposited by liquid-delivery spin MOCVD}, series = {Thin solid films}, volume = {519}, journal = {Thin solid films}, number = {17}, issn = {0040-6090}, pages = {5754 -- 5759}, language = {en} }
