Sustaining open innovation requires better understanding how collaborative efforts of contributors yield collective creativity. One of the significant problems in understanding emergence of collective creativity involves how collectives govern and coordinate the actions of individuals to maximize innovation output. Yet, relatively little is known about desirable organizing processes in open innovation communities. To this end, we examine the impact of governance mechanisms and conflict management styles on collective creativity in open source socioecologies. Systems model of creativity and proxy metrics for measuring potential for collective creativity are utilized to conduct a simulation study of Open Source software socio-ecologies. Findings suggest that decentralized coordination schemes such as emergent selection that are observed in utility communities along with moderate degrees of assertiveness and cooperation for conflict management result in higher incidence of innovation © 2009 IEEE.

While M&S has been widely used in engineering and computational sciences to facilitate empirical insight, optimization, and experimentation, the role of simulation in supporting early foresight phases of creative problem solving received less attention. We advocate models of creative cognition to rethink simulation modeling so that creativity is enhanced rather than stifled. Generative Parallax simulation (GPS) is introduced as a strategy and a generic and abstract specification for its realization is presented. GPS is based on an evolving ecology of ensembles of models that aim to cope with ambiguity, which pervades in early phases of model-based science. © 2009 simulation councils, inc.

Machine understanding is an essential and desirable cognitive ability for advanced software agents. In this article, we elaborate on: (1) yet another advanced feature, i.e., multi-understanding that is more than one understanding of an entity and (2) switchable understanding that is selecting one or more of the alternative understandings resulting in a multi-understanding. The rationale for the need and characteristics of multi-understanding as well as switchable understanding are clarified. This article is a background article;hence only the bases are covered. © 2009 simulation councils, inc.

There is no substitute to the intellectual disposition to innovate. To increase the value of creative thinking, ideas have to be transformed into wealth production through generation, promotion, and distribution of appreciated products and/or services in a timely and competitive way. To achieve these goals, philosophies of institutions and (virtual) organizations need to be nurtured to promote collective creativity and transformation of ideas into wealth production. The main objectives of the study are to explore and identify design principles for virtual innovation communities and to model innovation as an evolutionary process. A simulation study is conducted to systemically study and generate hypotheses regarding governance mechanisms that improve innovation output. Findings suggest that decentralized coordination schemes such as emergent selection that are observed in utility communities along with moderate degrees of assertiveness and cooperation for conflict management result in higher incidence of innovation.

This paper presents an agent-based simulation study that explores the effects of team behavior on the efficiency and effectiveness of software development organizations that pursue incremental and iterative processes. The conceptual model underlying the simulation framework is based on the fundamental tenets of organization theory. The organization-theoretic perspective to simulation modeling of software processes entails characterizing the components of organizational design, as well as types of team cooperation mechanisms that are associated with selected team archetypes. We present the simulation framework Team-RUP and use it to examine the extent of the impact of turbulence (i.e., employee turnover) on the effectiveness of software development under various team archetypes. We observe that asynchronous team cooperation models are less predictable than synchronous models. Also, teams that utilize bottom-up coordination strategies are more adept at responding to change.

RoboSoccer simulation is a complex multiagent system in which agents play the role of soccer players and the main goal is to have a perfect domain for research and investigation on artificial intelligence. This paper intends to propose a new scoring module to select the best point on the goal line to shoot, considering player's position, catching and shooting time difference, and distance to target. Two different approaches have been implemented for this purpose. The first one is a simple decision making policy and the latter one takes advantage of statistical measurement and fuzzy decision making. Results show the superiority of the proposed method performance in over our previous work implemented on Nexus 3D RoboSuccer team of Ferdowsi University. © 2006 IEEE.

Soccer simulation is an effort to motivate researchers to perform artificial and robotic intelligence research; and at the same time put into practice and evaluate the results. The research includes design and implementation of robotic soccer simulation algorithms in a multi-agent environment. In this paper, we propose a fuzzy two-phase approach, based on our previous crisp two-phase mechanism, for the soccer player agent's action selection. To do so, a fuzzy decision making approach was implemented which tells an agent what action to take, in a given situation. In comparison with similar implementations, our approach is faster and simpler to follow. This method is integrated into our Nexus soccer simulation team of Ferdowsi University. The outcome showed the superiority of the fuzzy two-phase selection method compared to the non-fuzzy one

On the Need for Contextualized Introspective Models to Improve Reuse and Composability of Defense simulations

引用

The Journal of Defense modeling and simulation: Applications, Methodology, Technology 2004年第3期1卷 141-151页

作者： Yilmaz, Levent Auburn Modeling & Simulation Laboratory M&SNet Department of Computer Science and Software Engineering College of Engineering Auburn University Auburn AL 36849 United States

Model reuse is a longstanding challenge within the defense simulation modeling community. While other disciplines successfully apply component-based approach to build systems, this approach has proven difficult to apply in simulation model development. The significance of employing explicit and distinct experimental frames to support reuse is already well recognized. Yet, characterization of the original context of a model is one of the least appreciated aspects and central to reuse and composability. Methods and tools are needed to provide mechanisms for structured representation and storage of context information, effective ways for retrieving it, and the possibility to relate it to the developer's intention. To this end, the basic model-simulator-experimental frame viewpoint is revisited to assert the role of context in reuse. The significance of separating concept, content, context, and simulator is discussed under the discrete-event system specification (DEVS) framework to provide a basis and rationale for contextualized simulation models. An abstract design strategy is presented to facilitate packaging and distribution of concept and context specification objects along with simulation models to improve reuse and composability. © 2004, The Society for modeling and simulation International.
