A Total Product System Concept - a case study of the smart (tm) automobile
Increasing demand from consumers plus EU legislation has raised awareness within the automotive production sector of the urgent need to reduce the environmental impacts from the three main stages in vehicle life â car manufacture, car use and end-of life vehicle processing. The paper reviews how the originator and manufacturer of the smart automobile has worked directly with its main system partners to address environmental issues in these three stages while optimizing performance across the parameters of commercial viability. This required the creation of strategic relationships within the supply chain. Overall, this innovative approach is viewed in the context of a total product system. The smart car highlights the following critical areas: use of modularity in product design and production facility layout; emphasis on partner participation from product creation to after-sales; and the use of highly customised build-to-order product system to 'green' the entire supply chain. In particular, the case study compares the process characteristics empoyed at the smart car factory, called 'smartville', with more traditional approaches to vehicle manufacture. It exmaines these issues in a preliminary attempt to establish the actual or potential reduction of environmental impact in the three stages of vehicle life, including the role of main suppliers in this process

'Smart' design: greening the Total Product System
About the book: Since the Rio summit in 1992, the paradigm of corporate environmental responsibility has gradually and consistently extended beyond complying with increasingly stringent environmental regulation and taking up the proactive initiatives of a few world-class companies. Research indicates that the business and financial performance of companies may depend directly on socially and environmentally responsible business practices. Many world-class companies now realize that customers and other stakeholders do not distinguish between a company and its suppliers. As a result, greening the supply chain is an innovative idea which is fast gaining attention in the industry. Greening the Supply Chain is a compilation of important chapters written by a diverse set of international authors which incorporates a broad variety of perspectives.

Reach modelling for drive-up self-service
People using a self-service terminal such as an automated teller machine (ATM) tend to adjust their physical position throughout a transaction. This is particularly apparent with terminals that are designed to be used from a vehicle (i.e. drive up automated teller machines or ATMs). Existing predictive tools tend to focus on static reach and provide limited predictions for how far people are willing to stretch to complete a task. Drive-up self-service products have 3 main challenges: the variability of vehicles, people and driver behaviour. Such conventional tools are therefore of limited use in understanding how much people are willing to move to use a self-service terminal. Work is described to build in-house predictive models based on 2 large empirical studies of reach in a drive up installation. These 2 studies assessed comfortable and extended reach from 10 vehicle categories. Extended reach was defined as stretching/leaning as far as participants would normally be willing to in order to complete a drive-up transaction. Findings from these studies indicated that participants are prepared to adopt more extreme postures at drive-up than in other situations with extended reach at drive-up being significantly different to what might be seen at a walk-up kiosk
Power Flow Modelling of Dynamic Systems - Introduction to Modern Teaching Tools
As tools for dynamic system modelling both conventional methods such as
transfer function or state space representation and modern power flow based
methods are available. The latter methods do not depend on energy domain, are
able to preserve physical system structures, visualize power conversion or
coupling or split, identify power losses or storage, run on conventional
software and emphasize the relevance of energy as basic principle of known
physical domains. Nevertheless common control structures as well as analysis
and design tools may still be applied. Furthermore the generalization of power
flow methods as pseudo-power flow provides with a universal tool for any
dynamic modelling. The phenomenon of power flow constitutes an up to date
education methodology. Thus the paper summarizes fundamentals of selected power
flow oriented modelling methods, presents a Bond Graph block library for
teaching power oriented modelling as compact menu-driven freeware, introduces
selected examples and discusses special features.Comment: 12 pages, 9 figures, 4 table
Engineering: good for technology education?
Recent curriculum changes in the educational system of Australia have resulted in study options being available in Engineering for senior secondary students to use for university entrance. In other educational systems, Engineering is playing an increasingly important role, either as a stand-alone subject or as part of an integrated approach to Science, Mathematics and Technology. These developments raise questions about the relationship between Engineering and Technology education, some of which are explored in this paper
The Fundamentals of Radar with Applications to Autonomous Vehicles
Radar systems can be extremely useful for applications in autonomous vehicles. This paper seeks to show how radar systems function and how they can apply to improve autonomous vehicles. First, the basics of radar systems are presented to introduce the basic terminology involved with radar. Then, the topic of phased arrays is presented because of their application to autonomous vehicles. The topic of digital signal processing is also discussed because of its importance for all modern radar systems. Finally, examples of radar systems based on the presented knowledge are discussed to illustrate the effectiveness of radar systems in autonomous vehicles
