Implicit Relations and Discrete Events in Process Simulation
نویسندگان
چکیده
Simulation of hybrid systems is considerably more complex than pure continuous-time systems due to blocking states, exceptions due to discrete events, and Zeno-type behavior. Rather than esoteric, hybrid systems are actually the norm for industrial process simulation when including the possibility of tanks running dry, vessels overflowing etc. This paper compares two modelling tools; (one block-diagram, one causal) for a simple, but typical process engineering problem. Matlab/Simulink illustrates a traditional block diagram modelling tool, while MathModelica with its strong emphasis on objects and symbolic manipulation was used to demonstrate a novel approach to modelling.

متن کاملAppointment process of open-heart surgery in Shahid Rajaei Heart Hospital using a discrete event simulation approach
Background: The waiting list is a list of selected patients in the surgical queue. If demand exceeds capacity, the waiting list grows rapidly, which may lead to unacceptable waiting for patients, especially those in need of acute medical care. Patients waiting for heart surgery are placed on the waiting list for surgery, and sometimes the waiting time is longer than patients expect. Reducing th...
متن کاملEvaluation and Ranking of Discrete Simulation Tools
In studying through simulation, choosing an appropriate tool/language would be a difficult task because many of them are available. On the other hand, few research works focus on evaluation of simulation tools/languages and their comparison. This paper makes a couple of evaluations and ranks more than fifty simulation tools that are currently available. The first evaluation and ranking is in th...
متن کاملAn Analytic Study of the Implicit Meanings in Tangsir
Semiotics is one of the theories of reading literary texts. This theory systematically studies the causes and factors involved in the process of production and interpretation of the signs. One of the main topics in semiotics deals with implicit meaning wherein the scholars examine the implied significance of the signs in addition to their explicit significance. Sadegh Chubak’s Tangsir is one o...
متن کاملDevelopment and Application of an ALE Large Deformation Formulation
This paper presents a complete derivation and implementation of the Arbitrary Lagrangian Eulerian (ALE) formulation for the simulation of nonlinear static and dynamic problems in solid mechanics. While most of the previous work done on ALE for dynamic applications was mainly based on operator split and explicit calculations, this work derives the quasi-static and dynamic ALE equations in its si...
