    A customised lean model for a Chinese aerospace OEM (Original Equipment Manufacturer)
    (Cranfield University, 2011-04) Li, Chao; Baguley, Paul; Tiwari, Ashutosh
    The aim of this research is to introduce Lean Thinking in a systematic and cost effective way; moreover, it is to bring Lean Principles and apply Lean Tools to the new aerospace companies. In particular the research will develop a customised Lean manufacturing model. The following objectives will be achieved during the research. 1); Investigate the principal features of Lean Thinking, and identify state of the art in Lean manufacturing implementation. 2); Identify the current situation of a specific Chinese aerospace company and the requirements needed in becoming Lean. 3); Develop a customised Lean model for applying Lean into a new Chinese aerospace company. 4); Validate the Lean manufacturing model by experts in the company and university. The Chinese traditional thinking is different from lean think. Therefore, to implement Lean in China will face some distinct barriers. The author attempts to resolve these problems through a customised lean model. According to the literature review and researcher‘s knowledge, there is no paper developing a model linking to the barriers of lean implementation in Chinese manufacturing. Therefore, the author will attempt to fill in this gap during the research. The questionnaire and assessment tool will be used to collect information from the company. Best practices will help to establish the structure of the model. However, in China, most companies implement lean through copying examples from the United States, UK and other Western countries without combining their current situation and culture. The contribution of this research is to develop a model to link Chinese barriers and a company‘s situation for lean implementation. Finally, this model will be validated by company and academic experts. The first validation is based on the sponsoring company. Other validations are achieved by academic experts and industrial expert.

    Development of a life cycle cost estimating framework for oil refineries
    (Cranfield University, 2011-09) Okafor, Okechukwu Peter; Baguley, Paul; Roy, Rajkumar
    This study is concerned with the understanding of some vital features of various life cycle costing methodologies and tools. Integrating these features with the refinery technical processes would assist in the development of a life cycle costing framework for oil refineries. The aim of this research is to develop a comprehensive life cycle cost estimating framework for the evaluation of not only the total cost and system effectiveness of new refineries but also the revamping, and maintenance of the existing refineries. Several conceptual life cycle costing models relating to various life cycle stages were reviewed, and their attachment to specific life cycle activities assessed. Furthermore, the literature review and the industry survey identified that a vital requirement for the development of a life cycle costing framework is the establishment of a structured conceptual life cycle costing model and a cost breakdown structure that will depict major cost categories and cost elements in the LCC framework. Consequently, a standard conceptual life cycle costing model and its cost breakdown structure were developed and integrated into a proposed LCC framework for oil refineries. A combination of the literature review findings and industry survey were also used to ascertain the current life cycle costing practice. It was identified that there is a lack of a practical framework to compare two or more options of refinery schemes for system effectiveness. This led to the development of a novel life cycle cost estimating framework that could be used in the evaluation of the total cost and system effectiveness of a new refinery when there is no performance data. Finally, the framework’s applicability and effectiveness was demonstrated through its application on a case study. The validation of the proposed framework and the cost estimates development within the case study was successfully carried out by experts from the industry and academia. Consequent upon the research findings, key areas for future work were identified. The implementation of the findings of this research within the industry could provide the much needed long-term benefit that comes with the formalisation of life cycle costing practice.

    Maintenance applications of augmented reality for the Chinese aerospace industry
    (Cranfield University, 2011-12) Ou, Peng; Tiwari, Ashutosh; Baguley, Paul
    Since augmented reality has not reached full maturity in use, it is not widely adopted within the aerospace industry. According to the literature review, minimal research efforts have been conducted to assess the cost-benefit or cost- effectiveness of augmented reality so far. Moreover, to the best of researcher’s knowledge, no research has been carried out to develop a systematic process for selecting and implementing augmented reality within the Chinese aerospace industry. This research will therefore aim to bridge the gaps. The primary aim of this research is to develop a process for selecting and implementing augmented reality to support maintenance within an aerospace company. The following objectives will be fulfilled in this research: 1) Identify different types of AR technologies and their strengths and weaknesses for maintenance; 2) Perform cost-benefit analysis for augmented reality within the maintenance industry; 3) Develop a process for selecting and implementing augmented reality in a range of activities. Data analysis and a questionnaire were employed to achieve these objectives. In the proposed cost benefits analysis framework, the costs of implementing an augmented reality system, both direct and indirect benefits, and the costs incurred by risks have been introduced. A proposed equation on the basis of above variables has been adopted to determine the feasibility of implementing an augmented reality system in terms of money. The proposed implementation framework has introduced a process which can be followed to develop a new augmented reality system. A set of criteria have been established for selecting augmented reality technologies. The two frameworks have been applied to a developed scenario and validated by experts from Cranfield University, as well as engineers from an aerospace company.
