Abstract

Purpose

The paper highlights the process of electric vehicles optimal design as an inverse problem and presents the global constrained optimization as the best way to solve it.

Design/methodology/approach

The electric vehicle optimal design is carried out by a new approach. It consists an electric vehicle design model managed by constrained optimization techniques. It includes sizing models for all drive train components and a vehicle dynamic model build in a new “design way” as an energy‐based model using the response surface methodology. The sensitivity of first simple sizing models can be evaluated by the experimental design method, giving information about the most important part of the model that must be improved.

Findings

The result shows the superiority of the constrained optimization technique that treats simultaneously the global optimization and the model adjustment. This method of simultaneous resolution is much more powerful than the successive resolution of each subproblem. The proposed “design approach” used for electric vehicle optimal design offer a large potential in the field of the complex systems design.

Originality/value

The electric vehicle design process is treated on a vehicle design model based on a design approach. It allows determining the drive train components specifications for imposed vehicle performances, taking into account the dynamic model of the vehicle and all components interactions. Furthermore, considering fine components sizing models, the components can be sized taking into account the whole system behavior in an optimal global design.

Abstract

Purpose

This paper aims to present the viewpoint of David Wright, head of External Affairs for SELECT, the Electrical Contractors' Association of Scotland. Its purpose is to highlight the adverse impact on the electrical sector of a disconnection between the Scottish Executive's education and vocational training policies.

Design/methodology/approach

The paper chronicles relations between the Scottish Executive vis‐à‐vis its education and vocational training policies and Scotland's electrical sector regarding the funding (or otherwise) of apprenticeships.

Findings

The paper points out that the Executive is simultaneously promoting a rise in the number of apprenticeships and a rise in the number of pupils staying on longer at school. The paper found that this contradiction has arisen largely as a consequence of the Westminster decision to fund apprenticeships for all 16‐18 year‐olds rather than provide social security payments for anyone unemployed within that age group, while the Executive is simultaneously encouraging 16‐18 year‐olds to stay on at school by funding them to do so. It found that an 18 year‐old leaving school seeking to embark on an apprenticeship will be unlikely to receive any funding, while a 16 year‐old will be guaranteed funding.

Practical implications

The paper covers SELECT's support for the policy promoted by the Scottish Parliament's Enterprise and Culture Committee for lifelong learning through the creation of individual learning accounts, whereby funding for vocational training is available to individuals of any age rather than restricted to narrow age parameters. It calls for funding programmes which recognise the practical consequences of the government's policies and which will enable people in their late teens and early 20s – and older – to train or retrain as apprentices.

Originality/value

This paper is of value to policymakers, employees, school pupils and apprentices.

Abstract

Purpose

Considering the well-known finiteness of resources and particularly in the light of previous concepts to ensure car-based mobility, this paper aims to outline to what extent the cost structure for sustainable mobility is still acceptable in the foreseeable future for the majority of people. The production and use of energy for mobility is a decisive factor for the future development of entire regions. This can be directly derived from the dramatically evolving energy cost in the recent years rooted in an increasing scarcity of known resources.

Design/methodology/approach

On the basis of available new technology components, researchers from the University of Magdeburg (Germany) have converted a conventional car into an electric vehicle. Hereby, energy efficiency and sustainability were in the direct focus of the product redesign. Furthermore, a LCC analysis complements the qualitative analysis.

Findings

Thus, a driving concept for electric mobility in the urban environment was drawn up which meets the criterion of suitability for everyday use due to an e-conversion. Moreover, the outstanding efficiency of the designed powertrain is demonstrated.

Research limitations/implications

Using the research electric vehicle Editha, the researchers point out which technical options can be inferred from available components for the creation of mobility in the urban environment. However, the source of energy is crucial to assess if the claim for sustainability is fulfilled.

Social implications

The paper illustrates that a monetary advantage of electric vehicles, such as the prototype Editha, arises after seven years due to disproportional purchase costs.

Originality/value

In this context, the proposed driving concept of the prototype represents a transitional solution from vehicles with central engine to hub wheel electric engines. In addition, Editha is the first roadworthy and suitable for daily use research vehicle using an individual electric motor for each rear wheel without manual gearbox.

Abstract

Purpose

Long haul freight transport imposes huge negative environmental externalities on society. Although these can never be entirely eliminated, they can be reduced. The purpose of this chapter is to analyse some of the many mitigating measures, or interventions, that can be used.

Methodology/approach

The approach used in this chapter is to review the literature and provide an overview of the main theoretical and practical mitigation measures available to transport operators.

Research limitations

There are literally thousands of possible mitigation measures and combinations that can be used by operators to reduce their environmental footprint. Each of these measures warrants a separate chapter. This chapter can only present an overview of the principle available measures. Although some mainland European examples are used, it is acknowledged that the examples used are somewhat skewed towards the United Kingdom.

Originality/value of the chapter

The value of the chapter is in bringing together some of the many measures and approaches that can be used to reduce the environmental externalities of long haul freight transport. Much of the information on such interventions is based on industrial and EU project sources rather than purely academic research and so is less likely to be found in academic journals.

Abstract

The case deals with the unforeseen uncertainties faced by Reva, the first electric car of India, while entering the Indian market. The company was able to take up the challenge of making an energy efficient car. As a new product, Reva achieved operational success, developing an electric, low energy car. Its marketing strategies had limited consumer pull and had to be strengthened to gain consumer acceptance. The ecosystem worldwide is looking for support from governments on the concept and the infrastructure of this product category.

Abstract

THE responsibility for materials handling methods, as for all other production methods, should be made the clear responsibility of the head of Work Study. The reasoning behind that firm conclusion is very logical. Industry in general depends for its success upon the application of some process such as machining or finishing of raw materials. Every such operation adds to its value and builds up a firm's turnover. It is therefore obvious that the more time there is devoted to conversion the less will be wasted on profitless storage or unproductive transport from one part of the works to another.

Abstract

Purpose

This paper aims to address the broad question of how organizations capture value from foresight exercises. Through a comparative case analysis, this paper looks at what firms do to make the information usable and create value. It explores factors that cause different firms to respond differently to the same trends. It analyzes the passenger car segment of the automobile industry and the response of six major firms to fossil fuel and changing environmental regulations through an analysis of their policies and strategic activities, such as new product development. It finds foresight to be an important link between firm capabilities and environmental changes.

Design/methodology/approach

This paper adopts the case approach to capture the linkage between the issue and the context (Yin, 1994) and uses multiple cases to explore the variables by comparing and contrasting the cases on key aspects (Eisenhardt and Graebner, 2007). As the paper ' s objective is to understand the similarities and differences between dominant firms in the sector, it chooses through theoretical sampling, six firms that have a presence in all the major regions of the world – two each from the USA, Europe and Japan – Ford, General Motors, Volkswagen, Renault, Toyota and Honda. This sample represents the firms and regions traditionally strong in the passenger car industry.

Findings

Thus, it is seen that the relationship that was posited in the conceptual model between the goal of the firms, the vision of the future and the nature of products and approach to technology/competence development seems to be valid. However, in addition, the paper perceives that some additional linkages that link between foresight and the goals and vision of the future seem to be influenced by the extent of uncertainty. In addition, the decisions regarding portfolio of products and approaches to technology and competence development seem to be also influenced by the perception of existing competencies and the external competitive context.

Research limitations/implications

This paper was based on multiple cases created out of secondary information, hence the constructs used are those which are perceived and stated.

Practical implications

The paper could help firms understand decisions related to technology choices in field involving high levels of uncertainty and competition.

Social implications

This paper could improve learning processes from foresight exercises, and enable strategic decisions to be taken on these.

Originality/value

Thus, this paper has explored the linkages between what firms perceive and state, and what is reflected in their actions. It has looked at this linkage from the perspective of foresight, and the strategic perspective of the firm. It has come up with additional issues and questions that influence this relationship. These can inform future research in this domain.

Abstract

This chapter provides a taxonomy of key rolling stock types and covers the key engineering principles. This chapter concentrates on the aspects of the rolling stock that make it sustainable in terms of passenger transportation; these aspects are primarily safety and crashworthiness. These are specific items that contribute to make the rolling stock and hence rail system more sustainable; passengers need to be confident that they are travelling in safe rolling stock and the vehicle consist, manufacturing technique or materials used should not compromise the crashworthiness aspects. For this reason, all aspects of this chapter reference vehicle safety and crashworthiness.
