A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...

Insurance companies are among the service organizations, which maintain close relationships with their clients by providing insurance services. Clients are the most important resource for service companies. And profitability of insurance companies undoubtedly hinges on clear analysis of client satisfaction and improved productivity of service providers. An important factor of client satisfactio...

Simulation is a well established what-if scenario analysis tool in Operational Research (OR). While traditionally Discrete Event Simulation (DES) and System Dynamics Simulation (SDS) are the predominant simulation techniques in OR, a new simulation technique, namely Agent-Based Simulation (ABS), has emerged and is gaining more attention. In our research we focus on discrete simulation methods (...

A timeline in Discrete-Event Simulation (DES) is a sequence of events defined in a numerable subset of R+. Discrete-Event Modeling and Simulation try to reproduce the behaviour of real-world experiments. Nevertheless, measuring the experimental data for science and engineering (which is later used for modeling and simulation) introduces the need for uncertainty quantifications. In modeling of C...

The application of discrete event simulation and system dynamics in the logistics and supply chain context. previously worked for a research project that introduces stakeholder participation and facilitation in discrete-event simulation modelling. Her research interests include the comparison of simulation approaches (discrete-event simulation and system dynamics), participative simulation mode...

Due to the close relation between object-oriented modelling and the domain of discrete event simulation (DES) the Unified Modelling Language (UML) has in the past been frequently applied for simulation modelling. However, most of this work is restricted to particular application domains or diagram types and based on the UML 1.x versions that had some drawbacks concerning dynamic modelling and f...

Recently there has been an increased focus on the environmental aspects of the manufacturing industry across the world. Boeing and the National Institute of Standards and Technology (NIST) have studied the incorporation of Life Cycle Analysis (LCA) parameters into Discrete Event Simulation (DES) as a means to analyze sustainable performance in the manufacturing area. For machining, accurate ana...

this paper deals with the problem of forbidden states in discrete event systems modeled by petri net. to avoid the forbidden states, some constraints which are called generalized mutual exclusion constraints can be assigned to them. enforcing these constraints on the system can be performed using control places. however, when the number of these constraints is large, a large number of control p...

After more than four decades of presence in the manufacturing industry, discrete event simulation has established itself as a powerful technology for a wide range of strategic, tactical, and operational applications in production, logistics, and supply chain management. Discrete event simulation software packages – although not entirely adequate – are relatively capable, andmethodologies for pe...
