First, the income tax microsimulation models and the related data requirements are discussed. Next, the processing of the applied data set is introduced and the idea of using direct data instead of samples developed along with applied data stream management principles. The discussion of data stream management issues turns subsequently into an analysis of model control aspects of data driven simulation. Finally, some practical experiences and applied technologies are discussed.

The simulation environment was created using the LabVIEW graphical programming system; a National Instruments software product. In this programming environment, the user can connect different procedures and data structures with “graphical wires” to implement a simulation model, thereby creating an executable simulation program. The connected individual objects simulate a discrete event problem. The chapter describes all simulation model objects, their attributes and methods. Another important element of the discrete event simulator is the task list, which has also been created using task type objects. The simulation system uses the “next event simulation” technique and refreshes the actual state (attribute values of all model objects) at every event. The state changes are determined by the entity objects, their input, current content, and output. Every mod...

Mathematical modeling and simulation should be an important part of the IS curriculum because only by mathematical modeling can a comprehensive view of the relevant processes and mechanisms involved in the information systems be obtained. This paper also proposes the use of a tool, called general-purpose Petri net simulator (GPenSIM) for modeling information systems. This paper presents the basics of GPenSIM and emphasis is given to its favorable characteristics for teaching mathematical modeling of information systems, such as 1) being discrete event-based, 2) using simple mathematics, 3) being programming language neutral, and platform independent.

Searching for microsimulation software development environment, the author concludes that opportunities of contemporary software technology are not exhausted; Web-based application development could provide better software architecture while fulfilling user requirements. The structure of the paper is as follows. The brief introduction defines microsimulation and categorizes the models used. The next sections focus in detail on two major approaches, database-oriented and web-oriented. The subsequent parts of the paper present two solutions for Web services, J2EE and.NET and discuss their respective merits and disadvantages. A sample model, using database-oriented approach with Web-service and final remarks concludes the paper. The major contribution of the paper is the presentation of new technology and its use for microsimulation. The sof...

It argues that any programs in Modelling and Simulation should recognize the multi- and interdisciplinary character of the field and realize the program in wide co-operation. The chapter starts with the clarification of the major objectives and principles of the Modelling and Simulation Program and the related degrees, based on a broad business and real world perspective. After reviewing students’ background, especially communication, interpersonal, team, analytical and critical thinking skills, furthermore some of the additional skills facilitating entering a career, the employer’s view and possible career paths are examined. Finally, the core knowledge body, the curriculum design and program related issues are discussed. The author hopes to contribute to the recent discussions about modelling and simulation education and the profession.

Die Eingabe der zu simulierenden Systemstrukturen erfolgt interaktiv graphisch durch das Aufbauen eines Blockschaltbilds. Dabei wird ein modulares Vorgehen im Sinne der strukturierten Programmierung unterstutzt. Bei der Implementierung wurde besonderer Wert auf Komfort, Einfachheit und Robustheit der Anwenderschnittstelle gelegt. SIDAS beinhaltet ein Konzept zur kombinierten kontinuierlich/diskreten Simulation, das eine effiziente Behandlung unstetiger Vorgange gewahrleistet. Die Moglichkeit der repetierenden Simulation mit Parametervariation erweitert den zu behandelnden Problemkreis auf Randwert- und Optimierungsaufgaben.

First, authors present the relevant characteristics of the microsimulation application field, where agent-based models can be developed, and examine some of the salient problems and opportunities. After a short analysis of a specific meta-database, Web-service technologies, agent-based modeling techniques are discussed. Authors show how selected technologies can be applied to support agent-based, dynamic microsimulation model development. Finally, references are made to the practical use and an example is presented. The paper concludes with a summary of research results and future plans

First, the application field and some of its major characteristics and requirements are introduced. After a short introduction and classification of microsimulation models, basic technological approaches for microsimulation model implementations are presented. Next, two major technologies, the database-oriented and the web-oriented approaches are discussed in detail. The two major solutions for realizing Web-services are J2EE and .NET. These two technologies are compared and their impact on microsimulation and related software technology shortly discussed. Final remarks conclude the paper.

This CD‐I disk, which is widely distributed and available also in Hungary, is a good example for illuminating the structure of such programs, their background in educational technology, and above all their roots, that lead back to programmed education. To cover this, we will also touch upon the special technology required for playing CD‐I programs, and the technical possibilities and limits of the programs themselves. We also wish to discuss the user‐friendliness of the disk from a psychologist's perspective.
