This paper describes a simulation specification language and execution environments that are being used to study the performance of distributed discrete event simulation. First, a simulation programming model based on Chandy-Misra distributed discrete event simulation is presented. Then, the Yaddes simulation specification language is described. Yaddes specifications are translated into C langu...

Discrete-event systems (DES) can be found as essential integrated subsystems in many complex systems, e.g. electrical power systems. Under-load tap-changing (ULTC) transformers which obviously have discrete-event behavior are widely used in transmission systems to take care of instantaneous variations in the load conditions in substations. In this paper, the voltage control problem in ULTC is s...

This contribution describes the methods used in a factory floor optimization process. The manufacturing process involves approximately 140 machines and is concentrated around a group of multipurpose CNC machines. We have analysed the current state of the manufacturing system by constructing a discrete event simulation (DES) model. The factory manufactures approximately 30,000 different products...

Introduction: Crowding and limited resources have increased the strain on acute care facilities and emergency departments (EDs) worldwide, limiting their ability to provide timely and safe care. These problems are particularly prevalent in third world countries where infrastructure and resource limitations are ubiquitous. Discrete event simulation (DES) is a computer-based simulation tool that ...

This paper introduces a logistics and transportation simulation that can be used to provide insights into potential outcomes of proposed military deployment plans. More specifically, we model a large-scale real-world military deployment planning problem (DPP) that involves planning the movement of military units from their home bases to their final destinations using different transportation as...

Existing approaches for modelling maintenance rely on oversimplified assumptions which prevent them from reflecting the complexity found in industrial systems. In this paper, we propose a novel approach that enables the modelling of non-identical multi-unit systems without restrictive assumptions on the number of units or their maintenance characteristics. Modelling complex interactions between...

Both system dynamics (SD) and discrete-event simulation (DES) are used to help understand and explain puzzling real world dynamics. But what are the similarities and differences between these two approaches and which should be used in a specific circumstance? These are questions few have ventured to answer. In this research the two approaches are compared by developing an SD and DES model of th...

This paper presents the application of discrete event system in the field of power system. In power system there are various components which required control and coordination when they are in operation. The theory of discrete event system has been applied in the application part of power system. The discrete nature of ULTC and discrete switching behavior of SVC are best suited for the supervis...

One of the most widespread techniques to evaluate various aspects of an existing manufacturing system is discrete-event simulation (DES). However, building a simulation model of a manufacturing system needs great resource expenditures. Automated data collection and model buildup can drastically reduce the time of the design phase as well as support model reusability. Since most of the manufactu...

Discrete event simulation (DES) studies in healthcare are thought to benefit from stakeholder participation during the study lifecycle. This paper reports on a multi-methodology framework, called PartiSim that is intended to support participative simulation studies. PartiSim combines DES, a traditionally hard OR approach, with Soft Systems Methodology (SSM) in order to incorporate stakeholder i...
