This paper reports on an effort to use both the system theoretic DEVS (discrete event simulation) formalism and the JavaBeans component model as a basis for a componentbased discrete event simulation framework. The result of the synergism of DEVS and JavaBeans is a powerful component-based simulation framework together with a set of flexible bean components for building simulation systems. Comp...

To reduce the computation requirement of large-scale network simulation, this paper presents a direct computing method for discrete event network simulation. In this method, many of the discrete events are replaced by direct computing, so the computation overhead for network simulation is decreased, yet the accuracy of simulation result is kept unchanged. Experiments show, compared with the tra...

This study presents a reduction of production disturbances of a shoemaking industry through discrete event simulation approach. The study is conducted at Peacock Shoe factory found in Addis Ababa, Ethiopia.  This factory faces line balancing problem that becomes production disturbance for its assembly lines. Detail time study is carried out for the selected shoe model using stopwatch. Assembly ...

This paper deals with the service performance analysis and improvement using discrete event simulation has been used. The simulation of the health care has been done by arena master development 14-version software. The performance measurement for this study are patients output, service rate, service efficiency and it is directly related to waiting time of patients in each service station, work ...

Parallel or Distributed Discrete Event Simulation (PDES) refers to the concurrent execution of a single discrete event simulation application on a parallel or distributed computing system. Most available PDES implementations provide user level library support for writing distributed simulation applications. We discuss how OS support can be designed to facilitate optimistic PDES of large, comple...

in recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. in the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. in this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (oopls) us...

This paper provides a framework for integrating fuzzy expert systems with discrete event simulation, which will be utilized to enhance the input modeling process in discrete event simulation. Predicting the activity output (i.e. duration) using fuzzy expert systems will provide a new modeling feature to discrete event simulation. In previous studies, fuzzy set theory was mainly utilized to cont...
