Simulation experiments can benefit from proper planning and design, which can often increase the precision of estimates and strengthen confidence in conclusions drawn from the simulations. While simulation experiments are broadly similar to any statistical experiment , there are a number of differences. In particular , it is often possible to exploit the(More)
This paper presents a conceptual framework for simulation modeling which emphasizes model reusability. Reusability is achieved through the provision of separate modeling constructs for physical, information, and control/decision elements of a system. These constructs contribute to a modular environment in which the modeling elements, once created, can be(More)
It has been stated that there is very less variability in cohesion, coupling and complexity of software packages within specific domains such as Graphical User Interface (GUI). This implies that software metrics show low variability within single domain and high variability between domains. This paper investigates the domain issue by creating hierarchical(More)
This paper describes the research efforts in the Center for Computer Integrated Manufacturing at the Oklahoma State University to develop an object-oriented modeling environment. After providing the underlying motivation for the research effort, some of the major research tasks are described. Highlights of this development effort are: physical and(More)
As technology is used to support team-based activities, one important factor affecting the performance of teams is the kind of mental model shared between team members. This paper describes a novel conceptual graph based methodology to study these mental models to better understand how shared mental models affect performance and other factors of a team's(More)
