The article deals with a general simulation model which has been created to analyse capacity of single-lane roundabouts. The simulation model is created in Witness and all input data that must be provided by users are defined via a web application which has been programmed to communicate with the general simulation model. The web application also presents some results of simulation experiments; the...
Environmental control and life support system(ECLSS) of the manned spacecraft is an important system to guarantee the safety and life support of the astronauts and the environment inside the space station. For the physicochemical regeneration type of ECLSS(PRLSS), because of its complicated physicochemical process, to analyze and evaluate the mass balance and operation performance through simulation...
Most of the existing contributions for container terminal analysis follow approaches based on optimization models, that are mainly useful to support strategic decisions about terminal container configuration. Many others contributions follow the simulation approach, which allows a detailed analysis but may lead to computational problems and is rather computer demanding, especially when resulting models...
A four-node wireless network model is designed based on NS2 simulation platform software. The network performance, such as System delay, Packet loss rate, Throughput and other key indicators are simulated in this paper. By running of TCP and UDP protocols, we make the analysis and evaluation to network performance from different aspects, and then, associated parameters were compared graphically with...
This paper first analyzed the technical background and the realistic demand of the web-based system of product customization and simulation. And then, the overall system structure and the work process were proposed, analysis and statement of the essential technology was proposed. Based on the research, a web-based system of product customization and simulation was developed primarily in JSP, and a...
The Disaster Response Network Enabled Platform (DRNEP) is a system that integrates a set of independently developed infrastructure and disaster simulators. This paper describes some of the architectural choices that we made for DRNEP. The overall system uses a master-slave pattern, with one master simulator orchestrating all of the others, based on a central system clock. As the various simulators...

The SSFNet (scalable simulation framework network models) is a network simulation tool using open source software with various network simulation applications. It has been designed for the expansion of network including topology, protocols, traffic, and etc, and is able to support simulation for the large-scale...
This paper describes the current state in the development of a computational steering framework that couples a visualisation front-end and an analysis back-end running independently of each other for interactive simulations from various fields of engineering and science. The objective of our software development is the realisation of a "Human-in-the-Loop" scenario that supports comprehension...
In order to meet the practical need of a number of scientific researchers during the task of simulation modeling and to overcome some shortcomings of the existing simulation modeling tools, this paper presents a new simulation platform KD-VisualSimIDE. It is emphasized on the whole structure of this platform, especially the design and implementation of the model editor which is an important part of...
How to improve system operation safety is an important problem faced by researchers and operators. The core of system operation is the human-machine interaction; so based on system safety analysis, it is an important approach to improve weapon operation safety by constructing man-in-the-loop simulation system to train the operators. Aiming to train the operators safety manipulations and emergency...
An issue that has confounded the understanding of software development in the past is the role that different numbers of developers play in the construction and subsequent evolution of software. In this paper, we investigate that facet of software using a configurable simulation framework as a basis. The framework uses 'agents' to represent developers and models the costs associated with first comprehending...
Propelled by application, simulation science and technology (SST) developed continuously, establishing relatively self-governed theory framework which include the similarity theory of simulation model and research object, simulation modeling theory, simulation system theory and simulation application theory. This paper brought forward that the similarity theory of simulation model and research object...
