Conceptual Modeling and Simulation
نویسنده
چکیده
System-level design requires behavioral models of its complex components in order to validate the designs, synthesize implementations and generate tests. Descriptions of these components are often only available as English descriptions. Developing behavioral models from natural language descriptions has been a tedious and time consuming task. This paper describes the semiautomatic generation of conceptual models from text and a simulator for these models. The conceptual modeling language is a knowledge representation notation (semantic hypergraphs), and simulation of these abstract descriptions based on the VHDL executiondescriptions based on the VHDL execution model is described. Simulation at the conceptual level avoids having to add the extraneous declarations and other syntactic artifacts necessary with more conventional description languages. These declarations not only take time, but also prejudice the

Application of conceptual hydrological models is an important issue in watersheds for researchers, especially in arid and semi-arid regions. The hydrological behaviors are complicated in such watersheds and their calibration is more difficult. In this article, the conceptual and semi-distributed SWAT model is used for a semi-arid Nishabour watershed with 9350 km2 area. Streamflow simulation is ...

متن کاملUTILIZING CONCEPTUAL MODELING IN THE STUDY OF ONE OF THE IRANIAN FRACTURED CARBONATE RESERVOIRS
A typical Iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. The modeling was carried out by using a fine-scaled Eclipse model in the single porosity mode (the fractures were explicitly modeled). The model was extended to a stack of 6 matrix blocks to understand block-to-...
متن کاملTowards a Component Based Conceptual Modeling Language for Discrete Event Simulation
Recent studies state the importance of conceptual modeling in simulation life cycles. Proper development of a conceptual model is critical for expressing the context, elements, relationships, limitations and purpose of the simulation study. Surprisingly there are many simulation projects that have no explicit conceptual model, a poorly or only partially developed conceptual model, or incomplete...
متن کاملApplication of A Simulation Algorithm for Dynamic and Nonlinear Analysis of A Liquid Propellant Engine
In this paper application of a simulation algorithm for dynamic and nonlinear analysis of a specific liquid propellant engine is presented. The mathematical model of the engine includes a set of nonlinear algebraic equations which is coupled with a set of time varying differential equations. In contrast to the existing liquid propellant simulation algorithms, the presented work does not depend ...
متن کاملCONCEPTUAL MODELING FOR SIMULATION : ISSUES AND RESEARCH REQUIREMENTS Stewart
It is generally recognized that conceptual modeling is one of the most vital parts of a simulation study. At the same time, it also seems to be one of the least understood. A review of the extant literature on conceptual modeling reveals a range of issues that need to be addressed: the definition of conceptual model(ling), conceptual model requirements, how to develop a conceptual model, concep...
