Abstract: This thesis presents the development of a multifaceted conceptual framework for discrete-event simulation and its implementation within an integrated visual simulation support environment (VSSE). The intertwined research objectives regarding the conceptual framework and the companion VSSE are presented. A literature review of related work is conducted. The core of the thesis describes the conceptual framework (called the DOMINO), the VSSE and each of the tools from its supporting toolset, and the VSMSL (Visual Simulation Model Specification Language). Three example model applications (bus route, traffic intersection, and branch operations examples) demonstrate the use of the VSSE and the underlying DOMINO. The thesis is evaluated using the research objectives as assessment criteria. The DOMINO is truly multifaceted. Both graphical and object-oriented, the DOMINO provides design and implementation guidance over the simulation model life cycle. The DOMINO is not restricted to specific problem domains but is independent of application domain. Several different perspectives for developing model component logic are available to modelers under the VSMSL. The VSSE demonstrates significant advances in integrated, automated support for model development which include graphical facilities for definition and specification and effective verification techniques. The VSSE underscores the contributions of the research effort and has helped to identify potential areas for future research.
