Computer based discrete event simulation (DES) is one of the most commonly used aids for the design of automotive manufacturing systems. However, DES tools represent machines in extensive detail, while only representing workers as simple resources. This presents a problem when modelling systems with a highly manual work content, such as an assembly line.(More)
For many years discrete-event simulation has been used to analyze production and logistics problems in manufacturing and defense. Commercial-off-the-shelf Simulation Packages (CSPs), visual interactive modelling environments such as Arena, Anylogic, Flexsim, Simul8, Witness, etc., support the development, experimentation and visualization of simulation(More)
Modelling human interaction and decision-making within a simulation presents a particular challenge. This paper describes a methodology that is being developed known as 'knowledge based improvement'. The purpose of this methodology is to elicit decision-making strategies via a simulation model and to represent them using artificial intelligence techniques.(More)
For many years discrete-event simulation has been used to analyze production and logistics problems in manufacturing and defense. In the early 1980s, visual interactive modelling environments were created that supported the development, experimentation and visualization of simulation models. Today these environments are termed Commercial-off-the-shelf(More)
This paper introduces the latest collaborative project work being carried out by Consultants at Lanner Group and Manufacturing Engineers at Ford Motor Company's PowerTrain Operations. The work involves aiding the design and optimisation of planned Engine Assembly Lines, by generating and experimenting with a complete simulation model produced using a(More)
Within the context of supply chain simulation, this paper introduces the generic runtime infrastructure for distributed simulation as a novel infrastructure for distributed supply chain simulation that promotes user transparency and extensible service provision. These are discussed with regard to a distributed simulation of a supply chain model (federation)(More)
This paper reports on continuing work that concerns research into the development of a commercial off the shelf (COTS) distributed simulation environment (federation) using the Generic Runtime Infrastructure for Distributed Simulation to support the interoperation of simulation packages such as Arena, Extend, Simul8, Taylor, Witness, etc. The main aim of(More)
The work reported in this paper is part of a project simulating maintenance operations in an automotive engine production facility. The decisions made by the people in charge of these operations form a crucial element of this simulation. Eliciting this knowledge is problematic. One approach is to use the simulation model as part of the knowledge elicitation(More)
The vision of grid computing is to make computational power, storage capacity, data and applications available to users as readily as electricity and other utilities. Grid infrastructures and applications have traditionally been geared towards dedicated, centralized, high performance clusters running on UNIX flavour operating systems (commonly referred to(More)
