More real systems have many components and their simulation requires significant execution times. The practical needs have conducted to distributed simulation rather than sequential method. Asynchronous parallel discrete event simulation (PDES) is studied and its methodology is presented. The paper presents the conservative methodology of PDES and illustrates it with a suggestive particular app...

1. Abrams, M., E. H. Page, and R. E. Nance, 1991, “Simulation program development by stepwise refinement in UNITY,” Proceedings of the 23rd conference on Winter simulation, Dec-91 Abrams, Page and Nance (1991) describe a UNITY-based methodology for the construction, analysis and execution of simulation models. Their methodology (based on work by Chandy and Misra) starts with a simulation model ...

Little work has been done to date in formally modeling concepts of lean construction, such as uncertainty, waste, flow, conversion, and push vs. pull techniques. This lack of formalization has been blamed in part on the inability of the project-management tools commonly used in industry to describe the construction process and its salient features at a level at which lean production can be stud...

This short note gives a brief overview of optimization approaches for stochastic discrete event simulation. In particular it shows how by the combination of different methods hybrid algorithms can be composed that allow a fairly efficient and reliable optimization of medium sized models.

A discrete event simulation library has been written in the Java language, based on the SIM++ library for C++. This allows live simulations to be incorporated into web pages and run remotely. This paper presents a performance comparison with the equivalent C++ simulator and discusses advantages and disadvantages of Java as a simulation language. 1 Motivation The primary purpose of writing simul...

JTED is a prototype of a Java-based framework for discrete event simulation, currently demonstrating parallel speedup on shared-memory multiprocessor platforms. JTED speci es a set of base classes for building simulations; the modeler de nes a particular simulation by creating derived classes, lling in the \hot spots" of the framework with active event-processing code, and registering instances...

Parallel simulation has not been widely accepted by the simulation practitioners due to the lack of language support and tools necessary for developing eecient parallel simulators. This paper describes the design of SPaDES (Structured Parallel Discrete-Event Simulation), a struc-tured parallel simulation workbench for developing portable simulation models, and a platform for designing experimen...

In print media industries networked production gains increasing importance. The relatively young XML based communication standard (JDF/JMF) allows to specify workflow models and data exchange. The proposed concept of a simulation framework for modelling of networked print production is based on an object-oriented approach implementing modules for the resources and controls applied in this parti...
