A manufacturing model to support data-driven applications for design and manufacture

Gutierrez, Arturo M. January 1995 (has links)
This thesis is primarily concerned with conceptual work on the Manufacturing Model. The Manufacturing Model is an information model which describes the manufacturing capability of an enterprise. To achieve general applicability, the model consists of the entities that are relevant and important for any type of manufacturing firm, namely: manufacturing resources (e.g. machines, tools, fixtures, machining cells, operators, etc.), manufacturing processes (e.g. injection moulding, machining processes, etc.) and manufacturing strategies (e.g. how these resources and processes are used and organized). The Manufacturing Model is a four level model based on a de—facto standard (i.e. Factory, Shop, Cell, Station) which represents the functionality of the manufacturing facility of any firm. In the course of the research, the concept of data—driven applications has emerged in response to the need of integrated and flexible computer environments for the support of design and manufacturing activities. These data—driven applications require the use of different information models to capture and represent the company's information and knowledge. One of these information models is the Manufacturing Model. The value of this research work is highlighted by the use of two case studies, one related with the representation of a single machining station, and the other, the representation of a multi-cellular manufacturing facility of a high performance company.

Learning from the radical change initiative in British aerospace military aircraft

Iqbal, Javid January 2003 (has links)
Academic researchers and practitioners are always keen to know more about organizational practices. Some experts even claim that academic researchers are ignorant about organizational knowledge. Given that the study is an attempt to provide an exemplar from real life in order to increase the organizational awareness of the academic community and practitioners. The objective of the study is to understand and learn the experience of a radical change initiative that took place within the Military Aircraft division of British Aerospace over the period 1993-98. The emphasis is on the effectiveness of the change methodology applied in the process of change. Open-ended interviews and documents were the major sources of the data used in the case study. The interviews reflected the actual experiences of those who were involved, while the documents provided contextual data and information on the key themes of the change. Nine change projects were examined which were introduced during five-year period. Analysis showed that there was a huge gap between the organization's practices and those of the benchmark companies. This gap is what BAe sought to lessen/remove through radical change initiative. The study postulates that the qualitative paradigm can shape the analysis of such a change initiative by contextualizing the phenomenon. Pettigrew et al's (1989) framework has beena pplied to assessth e change,w hich consistso f the context, the content and the process. The change programme was a successful attempt to increase internal efficiency, developing business partnerships and strengthening customer satisfaction. The study concludes that there is a strong relationship between the extent of management sponsorship, employees involvement, a flatter organizational structure, efficient use of technology, an effective change methodology and the success of such radical change initiatives. The experience of this company can be used in other organizations provided that their drivers for change are similar to those of the company investigated.

Investigation of the processes required for the automation of stitchmarking in shoe manufacture

Tout, Nigel R. January 1989 (has links)
This thesis describes a novel approach to the high speed automatic stitchmarking of shoe upper components by integrating an electrographic printer with a shape recognition system. A critical review of recognition system parameters selects the currently known shape parameters which are most suitable for use in a high speed recognition system with the large number of different shoe components found in a typical shoe factory. These are compared with the parameters actually used in the previously developed recognition system to be used for stitchmarking. A discussion of printing technologies suitable for marking shoe materials with computer generated patterns follows. It is concluded that an electrographic printer has the best combination of characteristics. There follows a description of experiments demonstrating xerography on shoe upper materials, and the design of a system integrating a low-cost laser printer to the recognition system which proved the concept of continuous automatic stitchmarking. With this performing satisfactorily, the system was converted to use a high speed printer requiring the use of an advanced graphics processor for handling the data transformations and interfacing with the printer. Modifications to the printer for operation with shoe materials are described, together with the need for a special toner. A full description of the resulting stitchmarking system is given, followed by details of analyses of its performance. Individual chapters are devoted to the accuracy, recognition efficiency, and the timing of the system. A potential bottleneck in determining the orientation of certain difficult shapes is identified, and faster methods for dealing with these are specially investigated. This concludes that the best approach is to optimise the present method and accelerate the calculations by using a more advanced microprocessor. A discussion of the general running of the machine includes details of problems which occurred with the modified printer mechanism and how these were overcome. Finally, suggestions are made for incorporation in an improved system capable of handling larger shapes with a tenfold speed increase.

Bleeding and Filtration of Cement-Based Grout

Draganovic, Almir January 2009 (has links)
Grouting is a common method of sealing rock around tunnels to reduce or stop water inflow. Successful grouting significantly minimizes the maintenance cost and safety of the tunnel. Some questions about bleeding and penetrability of the grouts have to be examined more closely to carry out a successful grouting. Bleeding of cement-based grout is a complex problem. Measuring methods used today originate from the measuring of the bleeding of cement pastes used in ordinary building industry. Whether bleeding measured with a standard method is relevant for bleeding in small fractures in rocks is one of the main questions in this study. The aim of the study is to illustrate what really happens with a grout during bleeding and which factors and processes influence it. In this way relevant measuring methods can be developed as well as the knowledge regarding interpretation of the measured results. The study has shown the most important factors which governs bleeding in cement-based grout. It has also shown that the results measured with standard methods are not relevant for bleeding of grout in rock joints and that voids in the joints caused by bleeding could be refilled during grouting itself. An important aspect of grouting is penetration of the grout. The penetration is defined as the length of how far grout penetrates in the rock through fractures from a bore hole. Filtration of the grout is a result of a plug building at fracture constrictions which reduces the penetrability of the grout. This is the other important issue discussed in the study which examines the question whether this can be measured by some measuring method and which factors and processes influence penetrability and filtration. A hypothesis of how the factors w/c ratio, pressure and relative constriction influence penetrability are presented and tested by special constructed measuring equipment. The results obtained by this measuring equipment are compared with the results measured with a penetrability meter. / QC 20100709

Competition, trade and industrial policy, and rent-seeking behaviour :

Shauki, Achmad. Unknown Date (has links)
Between 1987 and 1996 Indonesia went through successful major policy reforms which involved trade liberalization and deregulation.This thesis examines the effect of rent-seeking and government involvement in the economy on entry barriers and domestic competition in the Indonesian manufacturing sector during the policy reform period. / Thesis (PhD)--University of South Australia, 2008.
