An Object-Oriented Simulation meta-model to analyse supply chain performance
International Journal of Production Research, 2011Co-Authors: Roberto Cigolini, Margherita Pero, Tommaso RossiAbstract:This paper proposes a meta-model, which allows automatic building of Simulation models of supply chains. The proposed meta-model is made up from a user interface (to define the characteristics of the supply chain), an ad hoc objects library and a software application, to build the Simulation model. The meta-model can dramatically reduce to a few minutes or even seconds the time required to test a specific configuration of a supply chain and/or a specific management policy and, since the Simulation model is automatically built, neither the personnel skills nor the time available to build the Simulation model represent significant hurdles anymore. The meta-model has been applied to represent a simplified supply chain according to six different scenarios, where demand is deterministic. For each scenario a Simulation campaign has been performed and the outputs of the model (built through the proposed meta-model) correspond to the predicted results.

Object Oriented Simulation: A Modeling and Programming Perspective
2009Co-Authors: José M. GarridoAbstract:This tutorial is based on the book with the same title, published by Springer, 2009. The tutorial presents an introduction to object oriented Simulation modeling and using the OOSimL Simulation language for implementing the Simulation models. The emphasis is on early introduction to Simulation because Simulation is considered an important area in the computing curricula. An overview of relevant Object-Oriented modeling principles and then an introduction to Object-Oriented modeling and Simulation using the process interaction approach with the new language, OOSimL. In addition to the Simulation concepts, a brief exposure is included to developing models with the Eclipse integrated development environment. The Simulation language was designed and developed for teaching OO Simulation early in undergraduate programs in computing. Object orientation enhances the modeling and implementation of various families of systems. The OOSimL compiler generates Java code and C++ code. This Simulation language was designed and developed for teaching OO Simulation to students of computing (Computer Science, Software Engineering, and related disciplines). The language supports and promotes standard Object-Oriented (and software engineering) concepts and principles.

Simulation model development in information security education
2009 Information Security Curriculum Development Conference on - InfoSecCD '09, 2009Co-Authors: José M. Garrido, Tridib BandyopadhyayAbstract:The value of modeling and Simulation for education, training, and testing in information security has been documented in several studies. In this paper, we suggest that it is important not only to include the general use of Simulation in various courses of the security curriculum, but also to include the theory and development of Simulation models. We describe briefly the general features of Simulation models and tools for model development that we are using in computing education. A collection of educational Simulation tools have been created in the OOPsim project, for developing discrete-event Simulation models. The principal goal of this project is to develop newer Simulation tools and approaches for education in computing. The Object Oriented Simulation Language, OOSimL, was recently developed with partial support from an NSF CPATH grant. Two Object-Oriented Simulation models are discussed as typical examples discussed in a Simulation course on security: a model of a distributed denial of service (DDoS) and a model of simple firewall system. These models were developed with educational Simulation tools created in OOPsim project. We have also developed a course that emphasizes an approach to early introduction to Object-Oriented discrete-event Simulation. The DDoS Simulation model is implemented using the OOSimL Simulation language. The Firewall Simulation model was implemented in Java with the PsimJ2 object oriented Simulation package; other models have been implemented in C++ using the Psim3 object oriented Simulation package. The Simulation tools and model development are very useful for educating and training students and professionals in information security, computer science, software engineering, information technology, and in other related disciplines.

ACM Southeast Regional Conference - Teaching Object-Oriented Simulation with PsimJ Simulation package
Proceedings of the 42nd annual Southeast regional conference on - ACM-SE 42, 2004Co-Authors: José M. GarridoAbstract:PsimJ is a Java-based discrete-event Simulation package that supports the process interaction approach to Simulation. This paper presents insights of how this Simulation tool can help improve the teaching of Object-Oriented Simulation. The Simulation tool can also be used to help to understand and visualize a concept or a system. It can also be used to reinforce learned concepts through the design and development of a Simulation model. A comparison of MODSIM III and PsimJ is provided as an introduction to show that PsimJ has a comparative set of functionalities to MODSIM III, a once widely used commercial Simulation package.

An Object-Oriented Simulation architecture with real-time capabilities
International Journal of Production Research, 1995Co-Authors: Yasser Dessouky, Chell Roberts, Terrence BeaumariageAbstract:Simulation that approximates real-time system response has previously been used to train operators in the use of system controllers. These Simulations typically use architectures that are highly specific and tightly coupled to the system hardware. A formalized generic real-time Simulation architecture is presented to decouple the Simulation and provide a mechanism for implementation and rapid reconfiguration. This architecture distributes the state variables in the system by coupling them with manufacturing process equipment, specifically for the continuous process industries such as chemical, food and pharmaceutical. This design provides a mechanism for rapidly interchanging manufacturing equipment and Simulation model components for discrete and continuous Simulation, that facilitates operator training.

An Overview of Object-Oriented Simulation:
SIMULATION, 1998Co-Authors: Chell Roberts, Yasser DessoukyAbstract:With an immense increase in research, development, and application of object- oriented Simulation (OOS) over the past decade, there is evidence that this technology is becoming the choice for modeling large, complex, and/or distributed systems. This paper discusses the features of OOS that dispose it to modeling these types of systems and compares the OOS approach with traditional Simulation approaches. A review of OOS languages and environments is followed by a discussion of current issues pertaining to object- oriented Simulation.
