“…Ang & Zaphiris [21] have proposed a new method for sociability design and research through the use of simulation, and have developed an ABM to simulate and study the formation of social networks in a MMORPG guild community. Fishwick [22], on the other hand, introduces personal aspects of agents through first person perspective, inside an open-source, multi-user, virtual environment system called OpenSimulator.…”

Abstract-Massively Multi-Player On-Line Role-Playing Games (MMORPG) give us the opportunity to study two important aspects of computing: (1) large-scale virtual social interaction of people (players) and (2) the design, development and coordination of large-scale distributed artificial intelligence (AI). A common denominator for both aspects are the methods used to study them: social interaction can be described and simulated using agent-based models (ABM) whilst distributed AI is commonly modeled in terms of multi-agent systems (MAS). The important question to ask in both perspectives is how do agents organize in order to perform their tasks and reach their objectives? In the following paper we will present and overview of agent-based approaches to modeling MMORPG's agents including human players, artificial players (bots) and nonplaying characters (NPCs). We will put a special accent on useful agent behaviors, coordination and consensus mechanisms as well as organization and social network structure of agent societies.

“…The OpenSimulator is supported in both Windows and Linux-based operating environments and it supports both MySQL and MSSQL database technologies. Primary coding for OpenSimulator is developed using C# with a .Net framework (Allison & Miller, 2012); (Fishwick, 2009). …”

“…There are currently (14) services that are managed collectively by the ROBUST server that include: Assets Service, Authentication Service, Authorization Service, Avatar Service, FreeSwitch Service, Friends Service, Gatekeeper Service, Grid Service, Grid User Service, Inventory Service, Login Service, Presence Service, User Accounts Service, and the User Agents Service (OpenSimulator.org -HyperGrid, 2012); (Fishwick, 2009). Based on the functional criteria outlined earlier in Table 1, it was determined that OpenSimulator solution coupled with additional open source support applications not only met most of the established criteria but also provided a platform similar in design to Second Life, thus reducing some of the in-world learning curve required by both students and grid managers.…”

To better understand the technological requirements of academic institutions looking to implement an OpenSimulator virtual world grid, an observational study was performed to better understand the solution requirements. The purpose of this presentation is to provide an analysis of the parameters and considerations utilized to architect a scalable, open-source virtual world grid for use in various academic delivery scenarios. This specific case focuses on the detail leading up to deployment of the solution, and includes a discussion regarding solution selection and incorporation of various virtualization technologies to maximize institutional hardware resources based on established functional need. The computing resources utilized for this case were allocated via a virtualized infrastructure. Discussion and results include presentation of a proposed layered model outlining the solution elements and their relationships as well as various approaches to structuring and organizing in-world content and activity.

“…When thinking about environment, we can borrow from the virtual reality community where they have the term virtuality continuum. The virtuality continuum spans the real, physical, environment on the left and a virtual environment (Fishwick 2009) on the right. The word "virtual" is meant to describe a synthetic environment.…”

Simulation involves modeling and analysis of real-world systems. This tutorial will provide a broad overview of the modeling practice within simulation by introducing the reader to modeling choices found using six dimensions: abstraction, complexity, culture, engineering, environment, and process. Modeling can be a daunting task even for the seasoned modeling and simulation professional, and so my goal is to introduce modeling in two ways: 1) to use one specific type of model (Petri Net) as an anchor for crossdimensional discussion, and 2) to provide a follow up discussion, with additional non Petri Net examples, to clarify the extent of each dimension. For example, in the abstraction dimension, one must think about scale, refinement, and hierarchy when modeling regardless of the type of modeling language. The reader will come away with a broad framework within which to understand the possibilities of models and of modeling within the practice of simulation. INTRODUCTIONThe title of this paper is a little odd because it may sound as if I am referring to "six dimensional objects or space" as one might have in physical theories. However, the word dimension is used as a means to categorize important aspects of the modeling practice (Fishwick 1995). Models, for instance, can be abstract or they can be detailed. This observation is true regardless of the model type. Abstraction is a universal quality of objects and their behaviors. By thinking about abstraction, one is able to become a better modeler. There is also a danger of being too general. If I provide definitions for six dimensions, you may be at wits end to come away with a good sense of modeling. So, I will provide definitions for each of the dimensions, but also provide discussion grounded on one model type (a Petri net) for each dimension. Then, I'll employ various other examples for each dimension for a more thorough explanation. By moving from a standard Petri net model type to a free-form discussion, the dimensions can be better understood. Many of the references are from prior Winter Simulation Conference proceedings in the tutorial sections so that the reader can easily link to these freely available online proceedings papers. Before proceeding with the task of illustrating models, let's briefly define modeling. Modeling is the task of building a model, with a model consisting of a product containing features that emphasize certain attributes of a phenomenon. Modeling is so natural to humans that we do it routinely. A map is a model of territory-by taking a map on a journey, we can find our way around. The map serves to highlight, or surface, certain aspects of the territory. A toy train is a scaled down model of a train. Such scale models are often specified by their numerical scale: 1:10 or 1:100 for instance, with a 1:10 model being 1/10 th the size of the real train. Figure 1 shows a scale model of a favorite destination of mine, Bourton on the Water, which is a small village in Gloucestershire, England. You visit Bourton, park your car, and then l...
