Mallon, Michael John. "Manufacturing technology acquisition." Thesis, Cranfield University, 2002. http://hdl.handle.net/1826/3417.
Full textAbstract:
This thesis concerns the acquisition of newly developed production
equipment in factories. Types of Manufacturing Technology Acquisition
(MTA) can range from in-house development through to outright purchase
from a supplier. MTA projects often fail because the new equipment fails to
perform well enough or the expected financial benefits are not achieved.
The purpose of this research has been to find out how to select the right
manufacturing technology acquisition projects, and having chosen them,
how to make them successful.
Very little guidance on this subject was found in the literature. Therefore the
approach taken was to adapt techniques widely used in the much more
deeply researched field of New Product Development (NPD). The Success
Factor method was applied by conducting interviews with managers in a
number of factories to develop lists of factors thought to affect success or
failure in their MTA projects. The Portfolio method from NPD was adapted
to the case of managing a total MT`A budget, and developed through its use
in three annual cycles of equipment acquisition in the researcher's Company.
A formula for Expected Commercial Value in NPD was modified to
become Expected Manufacturing Benefit, and tried out in practice. An
important consideration in manufacturing equipment projects was
discovered to be the replication of projects which had proved successful,
and ways to incorporate this factor into the project selection procedure were
developed. A detailed case study of a single project was carried out, which
verified the validity of the findings at the level of a single project. This case
study also revealed the considerable impact that corporate strategic events
can have on technology acquisitions. This led to a case study on corporate
strategy in the Company being carried out.
Finally the findings were brought together to present a complete model for
managing MTA.

Full textAbstract:
Researchers posit that maximum benefit will accrue if there is a fit between the firm's strategies and its Advanced Manufacturing Technology (AMT) difftision. The existing literature discusses how the investment of AMT should be consistent with manufacturing strategy, however little attention has been given to an empirical examination of the link between manufacturing strategy and AMT, and the implications of the fit between these two on manufacturing performance. This thesis addresses that gap in the literature and thus seeks to examine the link between manufacturing strategy and AMT, and how the alignment between these two variables can affect the manufacturing performance.

Full textAbstract:
The degradation of natural resources as a result of consumption to support the economic growth of humans society represents one of the greatest sustainability challenges. In order to allow economic growth to continue in a sustainable way, it has to be decoupled from the consumption and destruction of natural resources. This thesis focuses on an innovative manufacturing technology called additive manufacturing (AM) and its potential to become a more efficient and cleaner manufacturing alternative. The thesis also investigates the benefits of accessing the technology through the result-oriented Product-Service Systems (PSS) approach. The outcome of the study is the quantification of raw materials and energy consumption. The scope of study is the application of AM in the scale model kit industry. The methods used are the life cycle inventory study and the system dynamics modeling. The result shows that AM has higher efficiency in terms of raw material usage, however it also has higher energy consumption in comparison to the more traditional manufacturing techniques. The result-oriented PSS approach is shown to be able to reduce the amount of manufacturing equipment needed, thus reducing the energy and raw materials used to produce the equipment, but does not completely decouple economic growth from the consumption of natural resources.

Amgen is a biotechnology company with manufacturing plants throughout the world. New manufacturing technologies are constantly being developed and implemented in order to address cost, quality, regulation, and competitive forces. However, deciding on the technologies to implement is difficult because there is much uncertainty and the regulatory constraints of old products need to be balanced with the need of manufacturing flexibility for new products. Interviews were conducted with executives at Amgen and other biotechnology companies to understand their current decision-making processes and no gold-standard decision-making process emerged. The current process at Amgen is a business case along with net present value (NPV). However, the process has been found to be somewhat biased and decisions are often made on gut-instinct and excitement. In addition, the business case often fails to capture some of the more subjective, intangible elements of new technologies. Therefore, a technology decision-making framework based on the Analytic Hierarchy Process (AHP) is introduced. The AHP is an objective, group decision-making approach. For usability and sustainability, commercial software from Expert Choice was used in case studies to validate AHP as a decisionmaking approach within Amgen. One case study looked at options to upgrade a clinical manufacturing facility. An AHP model was analyzed simultaneously with a typical business case and NPV analysis. The AHP model allowed management to understand the more subjective areas where the options differed and therefore was a suitable approach that added value. Another case study was performed looking at choosing a standardized drug substance container where five previous analyses had been performed, but no decision made. The AHP model allowed the different criteria to be combined in one model with cross-functional input so that management could make a holistic decision. The AHP approach had many benefits and using commercial software made the process easier for users and allowed for a more sustainaible process within Amgen.

Process Analytical Technology (PAT) became a well-defined concept within the pharmaceutical industry as a result of a major initiative by the FDA called "Pharmaceutical cGMPs for the 21st Century: A Risk-Based Approach." The FDA defines PAT as "a system for designing, analyzing, and controlling manufacturing through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials and processes, with the goal of ensuring final product quality." The biotechnology industry has started incorporating PAT in manufacturing, because of regulatory pressure and because the previous blockbuster-oriented business model is becoming less viable. This thesis proposes a methodology for evaluating PAT systems and delivers guidance on how to develop and implement them to effectively manage risk in biopharmaceutical manufacturing. The methodology includes guidance regarding identifying opportunities, evaluating and implementing novel analytical technology, appropriately applying acquired data, and managing change associated with PAT implementation. Experimental results from a novel PAT system that acquires light scattering and UV absorbance data to control chromatography during large-scale manufacturing are presented as a case study. The case study follows the methodology to show how a system optimized for a laboratory can be scaled for use in biopharmaceutical manufacturing.

Jin, Ning. "Perceptions on the Status of Lean-Manufacturing in Thermoplastics-Manufacturing Industry." TopSCHOLAR®, 2017. http://digitalcommons.wku.edu/theses/1916.
Full textAbstract:
The current study gathers thermoplastics professionals’ perceptions on the implementation of lean-manufacturing in the Thermoplastics-manufacturing industry through Qualtrics, which is a survey website. From the professionals’ perceptions, the current study infers the current status of lean-manufacturing implementation in the thermoplastic-manufacturing industry and identifies the best lean theories and tools for the industry. However, the results of the current study are not generalizable to the entire thermoplastic-manufacturing industry.
The current study reviews thermoplastic-manufacturing processes from the house of lean’s perspective. The foundations of the house are stability and standardization, the pillars are Just-In-Time (JIT) and Jidoka, the roof is customer focus, and the heart is employee involvement. Thermoplastic-manufacturing processes include extrusion, fiber spinning, film casting, film blowing, and injection molding.
The questionnaire of this survey includes six rating-scale, two multiple-choice (multiple-answer), and three closed-ended questions. The questionnaire was distributed to the respondents through email, LinkedIn, and Society of Plastic Engineers (SPE). The expected responses’ quantity was 35. Since some of the respondents did not complete the whole survey, the actual responses’ quantity for each question was between 39 and 45.
Based on the respondents’ perceptions, the implementation of lean manufacturing in the thermoplastic-manufacturing industry is incomplete. The industry professionals should put more attention and effort on the implementation of JIT and Jidoka. To fully implement JIT and Jidoka, thermoplastic-manufacturing companies should use lean tools that are related to JIT and Jidoka, such as kanban, takt time, heijunka, Value Stream Mapping (VSM), and poka-yoke, more often. Additionally, the thermoplasticmanufacturing industry practitioners perceived that the best lean theories for the industry were standardization, involvement, and stability, and the best lean tools were 5S, Total Production Maintenance (TPM), and poka-yoke

Farooq, Sami. "Manufacturing technology selection : a supply chain perspective." Thesis, University of Nottingham, 2007. http://eprints.nottingham.ac.uk/11033/.
Full textAbstract:
This thesis describes a technology selection framework for manufacturing technology selection. Technology selection has been identified as a major area of decision making in a company's manufacturing strategy and is highlighted as a manufacturing objective that can provide competitive advantage to a company. The research identifies the emergence of global supply chains as a major phenomenon that has revolutionised the global business environment. Considering the presence of global supply chains and their ever increasing importance the research has proposed a process for manufacturing technology selection keeping in view the supply chain perspective. The technology selection framework introduces the concept of risk evaluation of available technology alternatives for strategic technology selection. The risk associated with technology alternatives is evaluated in the shape of opportunities and threats. The decision making environment for technology selection is divided in a way to consider intra as well as inter-organisational factors. The classification of the decision making environment, inclusion of risk calculations and consideration of a supply chain perspective enables the developed technology selection framework to thoroughly evaluate a technology alternative before its strategic selection. The research presented in this thesis is composed of two main sections. The first section deals with the development of the technology selection framework, whereas the second section describes the application of the developed framework in an aerospace manufacturing company in detail. The application of the framework in industry helped in understanding the issues surrounding the technology selection process and provided an insight into how the existing technology selection processes can be improved and why it is necessary to address the supply chain factors functionally as well as holistically in manufacturing technology selection. The major contribution of this research is a technology selection framework integrating manufacturing and the supply chain. Academically the research establishes a link between manufacturing technology selection and the supply chain and emphasises the importance of alignment between manufacturing and supply chain objectives.

Strategic technology planning is a core competency of companies using technological capabilities for competitive advantage. It is also a competency with which many large companies struggle due to the cross-functional knowledge that needs to be shared, the varying perspectives that must to be aligned, the complicated network of dependencies that need to be understood and the high-degree of uncertainty involved in technology planning. Technology roadmapping has proven to be an effective strategic technology planning technique that can overcome these challenges. This thesis reviews literature on technology roadmapping and expands on this literature by applying these techniques to roadmapping the manufacturing technology. While the existing literature largely focuses on roadmapping the technologies that will directly deliver value to the customers, this thesis focuses on the technologies that indirectly deliver value to the customer. In an advanced products company, examples of the former and latter technologies are the product and manufacturing technologies, respectively. This distinction has important implications for the management of these technologies. Technology roadmapping is a powerful and flexible technique that must be tailored to the strategic context where it will be implemented. Through a case study of the development and implementation of manufacturing technology roadmapping at Raytheon Space and Airborne systems, the author seeks to provide a general set of guidelines for roadmapping a company's technology that indirectly add value to the customer.

Manufacturing technology roadmaps align manufacturing capability development to product development and the driving business need. Roadmaps allow an executable business strategy to be communicated to all levels of an organization reducing the time and resources required to bring new technology to market. This thesis examines the creation and sustainment of manufacturing technology roadmaps at Raytheon Space and Airborne Systems (SAS). It demonstrates how by using a stakeholder analysis and demonstrating a positive value proposition to all stakeholders agreement and adoption can be created across a large organization.

Full textAbstract:
3D textile performs offer a high potential to increase mechanical properties of composites and they can reduce the production steps and costs as well. The variety of woven structures is enormous. The algorithms based on the conventional weaving notation can only represent the possible woven structures in a limited way. Within the scope of this dissertation, a new weaving notation was developed in order to analyze the multilayer woven structures analytically. Technological solutions were developed in order to guarantee a reproducible preform production with commingled hybrid yarns. Terry weaving technique can be utilized to create vertical connections on carrier fabrics, which makes it suitable for the development of complex profiles. A double rapier weaving machine was modified with electronically controlled terry weaving and pneumatic warp yarn pull-back systems. Various spacer fabrics and 3D profiles were developed. A linear take-up system is developed to assure reproducible preform production with a minimum material damage. Integrated cutting and laying mechanisms on the take-up system provides a high level of automation.

In-Space Manufacturing (ISM) promises to revolutionize space systems by reducing mass, lowering costs, and enabling entirely new designs through the orbital fabrication of components in the space environment in which they are intended to operate for their entire life. Because ISM changes many long-standing launch-related design constraints, a new approach for the design and fabrication of space systems must be developed. Technology development planning for ISM is complicated by the existence of various proposed commercial ISM architectures, each with their own technologies, products, and costs. Instead of attempting to estimate these highly uncertain quantities, this analysis informs ISM technology targeting by identifying the key system drivers, maximum allowable lifecycle cost, and minimum required performance for an ISM architecture to be cost-effective relative to the existing launched approach. This analysis is accomplished by first forming generalized classes of ISM applications based on the design constraints relaxed using ISM, such as launch loads, fairing volume, standard gravity, and launch schedule. These generalized classes, which include structurally optimized systems, larger-than-launchable systems, Earth-return systems, and on-demand manufactured systems, are shown to be collectively exhaustive, but not mutually exclusive. For each of these classes, a bottom-up cost model is developed that captures the impact of key system drivers on lifecycle cost. Then, Buckingham Pi theorem is used to identify nondimensional groups of input design variables, such as the ratio of areal density of launched components to that of ISM components, the ratio of ISM facility mass to that of ISM components, the ratio of ISM product sale price to launch cost, or the ratio of launch cost to material cost. The breakeven point between launched and ISM components is identified as a function of these parameters and nondimensional groups, which serve as technology development targets for commercial viability. It is shown that the presented approach can inform technology development efforts by evaluating the commercial viability of historical, current, proposed, and notional ISM concepts across a broad application space. The best ISM applications can be identified as having a high allowable facility cost without requiring a large total ISM product mass. For the structurally optimized class, ISM of solar arrays appears promising because structural mass can be reduced by up to 85% relative to the technology goal for launched solar arrays. However, ISM solar array mass savings are fundamentally limited by solar cell mass, which can total 5 kg/kW. Of the Earth-return concepts considered, ISM of ZBLAN optical fiber appears most promising with an allowable facility cost of $1.35B based on just 125 kg produced over a five year period at its sale price of $11M/kg. The commercial viability of ISM of ZBLAN is relatively insensitive to launch costs. Interestingly, falling launch costs improve the business case of Earth-return ISM concepts, while weakening that of ISM for structural optimization.

Full textAbstract:
Accounting for output per worker differences across countries has been an ongoing topic of research in economics. This thesis expands upon standard approaches by allowing for technological heterogeneity and exploiting firm and worker level data to determine the microeconomic sources of variation in both productivity and earnings. An intercontinental comparison using production functions for the Ghanaian and South Korean manufacturing sectors in Chapter 2 finds, in contrast to the conclusions of much of the macroeconomic literature, that there is no difference in total factor productivity (TFP). The microeconomic sources of the difference in value added per worker lie within the technology of firms, which is defined as the way in which inputs are used. Two important dimensions of this difference are the larger role of material inputs and the much lower rate of return to schooling in Ghana. In Chapter 3 a more general specification investigates intra-African variation in production, which is much smaller than the intercontinental difference. The pattern of cross-country heterogeneity is that, as GDP per capita rises, the relative input of materials falls, those of capital and labour rise and the returns to education increase. Differences in TFP are limited. Possible sources of the low returns to schooling in Ghana are investigated in Chapter 4 using earnings and production functions. Conditional upon selection into occupations, the only group of workers for whom education appreciably increases earnings are those employed in skilled jobs with more than ten years of education. The evidence is consistent with a lack of technological sophistication being the source of these low returns. Investment in new production processes by firms will increase the return to education and raise incomes and output. Reducing the share of intermediate inputs in production is key to the transition from low to high productivity activities. Technology is the critical element that can explain the performance of manufacturing firms across countries.

In this report, a future scenario concerning the economic direction of the computing industry has been presented. This future scenario was based on past developments within the computing industry. The continued miniaturization of semiconductor components was discussed based on observed trends for transistors. The physical limitations for transistor devices were also addressed. The use of x-ray lithography for the construction of devices on a 3nano-scale2 was considered. Next, cost trends within the microelectronics industry were explored. Although the cost per transistor has been observed to decrease, total equipment costs and facilities costs were observed to rise.
Trend extrapolation was next used to predict the future cost per transistor and the number of transistors per chip. By taking the product of these two predicted quantities, an equation for the future manufacturing cost per chip was determined. A parametric cost estimation model (VHSIC Model) for the prediction of avionics computer system costs was modified to reflect the future performance parameters of nanoelectronics. Using data from the x86 design of Intel Microprocessor Chips, undetermined parameters of the Modified VHSIC Model were calculated. Next, future performance parameters were used in the model to predict the initial selling price of future chips. The resulting predictions from this model indicated that chip prices are expected to increase while the price per electronic function will decrease. Finally, profit-time models for semiconductor chips and transistors were derived. These models were used to predict the future profit for a chip or transistor.Master of Engineering

This thesis proposes a cost based grouping procedure for Group Technology. The procedure is a two-stage graph partitioning approach to determine machine cells. Costs of work-in-process inventory, machine depreciation, machine setup and material handling are used as a basis for grouping. The procedure begins by selecting economic lot sizes for each part type and converting these values to machine requirements. The first stage assigns parts to machines of a common type. The second stage groups individual machines to cells, with each machine cell having a number of machines between chosen lower and upper limits. An additional check is given to the final groupings to see if adding a machine of any type can result in savings on the intergroup material handling cost. The process may iterate by next obtaining updated setup times and restarting.

Development of new technology is critical to the growth and success of technology-driven companies. New technology is generated in a number of ways, one of the most important being the company's own internal research and development department. This thesis examines the transfer of technology developed in an internal R&D group into product development groups across multiple business units of the company. An analysis of the company's documented development process activities and metrics will establish the context in which technology is transferred. The company's organizational structure is a central R&D group that supports two market-focused business units, each with their own technology development group. A series of five case studies tracking technology that was developed in the central R&D group and transferred to the business units will illustrate the way technology development activity occurs in the organization. The R&D organization is structured to support research, applied research, and development activities that drive both incremental and radical innovation, and it is managed to support a balance of short term and long term strategic goals.
(cont.) The case studies highlight the fact that project definition should include attention to the goal the project is intended to achieve, the type of innovation used to achieve that goal, recognition of the phase or maturity of technological research in that area, and how those aspects of the project should shape the development process and plans for communication and collaboration.

The biomanufacturing industry is changing due to increasing globalization. However, it is changing differently from other high tech industries like software/ semiconductor/ automobiles. In this study we use global biomanufacturing investment data, industry survey data as well as interviews with members of industry and academia to understand the extent of microbial biomanufacturing activity (total volume, number of facilities, type of facilities) and nature of biomanufacturing activity (complexity of products and processes across both mammalian and microbial production) in different regions of the world today. The study shows that traditional centers of expertise in US and EU still house most of the worlds biomanufacturing capacity. The facilities in US and EU perform a larger number of operations within their facilities and also more technically complex operations than facilities in Asia. US facilities support the most complex products (median unit operations =13) and processes (cell culture, purification) and maximum average products per facility(12.2). Asian facilities support simpler products (median unit operations =7), simpler processes (fermentation, fill/finish) and fewer products per facility on average (3.25). These results support the idea that managing technical complexity is one of the biggest challenges in biomanufacturing today and it can determine where a biologic can be manufactured. While economic forces push manufacturing of biologics to low cost locations, the need to develop expertise may prevent manufacturing from scattering across the world. Instead, there may be a more guided flow to locations with an expertise in certain types of products and processes.

Iqbal, Numan. "Technology catch-up actions for manufacturing companies in Pakistan." Thesis, Cranfield University, 2004. http://dspace.lib.cranfield.ac.uk/handle/1826/4735.
Full textAbstract:
Technological development in manufacturing companies has been considered as a key
contributor to the economic development of nations. Research has confirmed that the
contribution of technological development to national wealth is more than 50 %.
The objective of this research was to explore the steps which could help manufacturing
companies in Pakistan to catch-up in technology with the leading companies in the
world.
The first step was the quantitative measurement of the status of technology in a sample
of manufacturing companies in Pakistan through a new survey method.
Numerous interviews with experienced senior factory managers in Pakistan then
explored the issues, including barriers to technology improvement, their solutions,
actions that could promote technology, and stages required for catch-up in technology.
Three case studies included in this process helped in understanding the issues. The
outputs were the lists of barriers, solutions, and actions, each organised in a new-found
framework of issues essential in technology development, and a four-stage technology
catch-up path.
A survey then ranked the barrier and action factors in order of their importance. The
most important ones were compiled in the form of action plans for factory managers and
government policy makers.
Similar barrier, solution, and action factors were then explored in the literature on
manufacturing companies in successful East Asian countries using content analysis, and
ranked in order of importance. This also resulted in action plans and a four-stage
technology catch-up path.
The results from the Pakistan research were then compared with the results from the
literature, and combined to develop comprehensive action plans.
This research found that catch-up in technology was possible through specific actions in
defined directions by the factory managers themselves without explicit help from the
government, although such support can be very valuable.

This thesis explores a variety of logistics strategies for Qualcomm Wireless Business Solutions (QWBS), focusing on the OmniTRACS system and MVPc display. I develop and apply a model that considers the interactions of inventory processing and inventory movement in the context of total supply chain costs. My goal is to minimize purchased product inventory while reducing product lead-times. Without a formal model, supply chain organization decisions tend to replicate existing designs because it is difficult to find a better solution by trial and error due to the numerous alternatives and the number of variables involved. To develop an understanding of the issues at QWBS, I began by researching technology manufacturing supply chains. I also developed a cost model for analyzing QWBS's supply chain. The final form of this model is a series of spreadsheets which accepts cost data, lead times, and variable demand as key inputs, and produces overall supply chain cost distributions. The supply chain is modeled as a series of processing nodes and transfer links. The model derives its results by simulating variable demand and summing the cost contributions of the nodes and links for each trial. The supply chain research and the cost model provide Qualcomm with a realistic and usable tool to compare both intra- and inter-company supply chain designs in terms of overall channel costs. Furthermore, my results suggest that QWBS should focus its direct shipping supply chain efforts on customers whose demand variation is smaller than QWBS's overall customer average.

The purpose of this research is to provide an academic, external perspective to facilitate the implementation and development of a new internal organization for Raytheon Missile Systems (RMS) with a focus on strategy and the organization. The new organization, named the Advanced Manufacturing Development Center (AMDC), is chartered to work concurrently with the design community to develop state-of-the-art manufacturing technology to compliment the next generation engineering designs. This thesis documents the efforts of a company implementing change detailing the specific challenges they faced. The principle lessons learned during the course of this project are (1) that effectively introducing change is very difficult and depends largely on thorough planning and understanding the culture and (2) that manufacturing innovation and development is a critical step to improving the manufacturing capabilities and providing a competitive advantage to a company. The defense industry is undergoing a lean transformation that focuses on "Better, Faster, Cheaper" defense systems demanding better products within a faster development timeframe at cheaper development and production costs. Defense companies have an external push to improve their manufacturing capabilities. In the context of the defense industry, adapting to change is a slow process given the industry's clockspeed and historical development. Making the challenge of effective implementation even more difficult is the lack of urgency at RMS's due to their success in the marketplace. Benchmarking and organizational studies specific to the industry and the company were conducted to identify best practices to provide a basis for the development of the AMDC. This project uses academic research to identify existing theories on manufacturing innovation and organizational change to overcome the socialization and cultural issues that ensued from implementing change and to improve the potential sustainability and impact of the AMDC. An implementation roadmap and operational model were generated that combined the best practices found in industry and academic theories that would help meet the objectives of the AMDC.

Full textAbstract:
Computer aided design and manufacturing (CAD/CAM) has been a focal research area for the manufacturing industry. Genuine CAD/CAM integration is necessary to make products of higher quality with lower cost and shorter lead times. Although CAD and CAM have been extensively used in industry, effective CAD/CAM integration has not been implemented. The major obstacles of CAD/CAM integration are the representation of design and process knowledge and the adaptive ability of computer aided process planning (CAPP). This research is aimed to develop a feature-based CAD/CAM integration methodology. Artificial intelligent techniques such as neural networks, heuristic algorithms, genetic algorithms and fuzzy logics are used to tackle problems. The activities considered include: 1) Component design based on a number of standard feature classes with validity check. A feature classification for machining application is defined adopting ISO 10303-STEP AP224 from a multi-viewpoint of design and manufacture. 2) Search of interacting features and identification of features relationships. A heuristic algorithm has been proposed in order to resolve interacting features. The algorithm analyses the interacting entity between each feature pair, making the process simpler and more efficient. 3) Recognition of new features formed by interacting features. A novel neural network-based technique for feature recognition has been designed, which solves the problems of ambiguity and overlaps. 4) Production of a feature based model for the component. 5) Generation of a suitable process plan covering selection of machining operations, grouping of machining operations and process sequencing. A hybrid feature-based CAPP has been developed using neural network, genetic algorithm and fuzzy evaluating techniques.

This exegesis outlines the procedures, processes and methodology used in developing a significant body of studio work that investigates the dominance of the screen-image in contemporary art and culture. Following the established modes of practice-based research, the outcomes can be seen in two phases: the work developed and exhibited during the candidature, and the culminating submission exhibition. All the outputs resulted from intensive studio practice, although without using the studio as a hermetic environment, but rather as the base for practice attuned to the feedback loop of constant interaction and review of the most recent developments in exhibition practice and technique. All of the works discussed in the exegesis and developed towards the final submission demonstrate the progressive interrogation of the production of a screen-image from primitive forms such as the camera obscure through to the high-definition digital television image. A clear evolution is evident in the forms and strategies for dealing with the relationship between the screen and the machinations and industry that is behind bringing the image to fruition. The final submission exhibition brings these processes to a point of conclusion, if not resolution, where the material production experience and knowledge of the limits of the technology combine to demonstrate a new understanding of the impact of digitally generated screen-images and the role of the image in the age of new technology...Thesis (PhD Doctorate)

Full textAbstract:
Additive manufacturing (AM), also called 3-dimensional printing (3DP), emerged as a disruptive technology affecting multiple organizations' business models and supply chains and endangering incumbents' financial health, or even rendering them obsolete. The world market for products created by AM has increased more than 25% year over year. Using Christensen's theory of disruptive innovation as a conceptual framework, the purpose of this multiple case study was to explore the successful strategies that 4 individual managers, 1 at each of 4 different light and high-tech manufacturing companies in the Netherlands, used to adopt AM technology into their business models. Participant firms originated from 3 provinces and included a value-added logistics service provider and 3 machine shops serving various industries, including the automotive and medical sectors. Data were collected through semistructured interviews, member checking, and analysis of company documents that provided information about the adoption of 3DP into business models. Using Yin's 5-step data analysis approach, data were compiled, disassembled, reassembled, interpreted, and concluded until 3 major themes emerged: identify business opportunities for AM technology, experiment with AM technology, and embed AM technology. Because of the design freedom the use of AM enables, in combination with its environmental efficiency, the implications for positive social change include possibilities for increasing local employment, improving the environment, and enhancing healthcare for the prosperity of local and global citizens by providing potential solutions that managers could use to deploy AM technology.

Full textAbstract:
The purpose of this study is to determine the required attributes and competencies required for a graduate from a manufacturing engineering technology baccalaureate program. A document called “Competencies of Manufacturing Engineering Technology Graduates” was compiled in October 2004. This document lists twelve attributes thought to be important for MET graduates: Leadership, Professionalism, Creativity and Problem Solving, Management, Materials, Processes, Quality, Systems, Design, Communication, Safety and Environmental Issues, and Global Awareness. Under each attribute is a list of five to seven competencies creating a total of seventy-three competencies for graduates of an MET baccalaureate program. This list of attributes and competencies was converted into a survey for the purpose of evaluation by two manufacturing groups: educators and industry representatives. Overall, educators and industry representatives rated the attributes and competencies as important. Ninety-nine percent of the combined educator's and industry representative's competency questions had a mean response of 3.50 and above. Therefore, the competencies are relevant for MET graduates. It was determined that educators did significantly differ from industry representatives for their ratings of the attributes, but educators did not significantly differ from industry representatives for their ratings of the competencies. Generally, industry representatives rated attributes less highly than educators; however, the pattern of responses was similar across educators and industry representatives. The rankings of each attribute section from those rated most important to those rated least important were as follows: Professionalism, Communication, Creativity and Problem Solving, Manufacturing Processes, Design, Safety and Environmental Issues, Quality, Materials, Leadership, Management, Manufacturing Systems, and Global Awareness. Current literature mentions aspects of manufacturing that are considered important and these include: global or international awareness, lean manufacturing, life long learning, and communication. This survey indicated that the Global Awareness section was rated the least important of any section. The lean manufacturing competency had an average ranking out of all seventy-three competencies. Communication has been an important concern for MET graduates since the earliest studies and the survey results suggest that communication continues to be highly valued. MET educational programs should provide many opportunities for students to improve their communication skills.

Full textAbstract:
Having an efficient production is vital for companies that are facing highly demanding customers along with tough competition. In addition, the production layout has a significant impact on the production efficiency hence it the choice of production layout is an important question to consider. A common production layout is the assembly line whereas companies with products that are not adequate for assembly line production; are seeing advantages of working with assembly lines. An example is the modular house manufacturing industry. Therefore, the purpose of the study was to investigate how an assembly line for modular house manufacturing and the related material supply may be designed in order to increase the overall efficiency of the manufacturing process. A single case study has been conducted at Zenergy AB, Skillingaryd. Empirical data has been collected through various sources; interviews, observations and document studies. In addition, a literature review has been conducted. The theoretical framework and empirical data has been established by the means of pattern matching and further on data analysis was done thus the results of the study were acquired. To conclude, it is shown in the results that implementation of an assembly line for modular house manufacturing can be beneficial despite the fact that its products are not adequate for assembly line production. Further on, there are three main critical factors to consider during the assembly line design process for modular house manufacturing. The critical factors are; line balancing, dry time and bulky materials. The critical factors will in turn have a significant impact on the choice of the assembly line production layout and the related material supply.

Full textAbstract:
This thesis is concerned with the means by which the state in Britain has attempted to influence the technological development of private industry in the period 1945-1979. Particular emphasis is laid on assessing the abilities of technology policy measures to promote innovation. With that objective, the innovation literature is selectively reviewed to draw up an analytical framework to evaluate the innovation content of policy (Chapter 2). Technology policy is taken to consist of the specific measures utilised by government and its agents that affect the technological behaviour of firms. The broad sweep of policy during the period under consideration is described in Chapter 3 which concentrates on elucidating its institutional structure and the activities of the bodies involved. The empirical core of the thesis consists of three parallel case studies of policy toward the computer, machine tool and textile machinery industries (Chapters 4-6). The studies provide detailed historical accounts of the development and composition of policy, relating it to its specific institutional and industrial contexts. Each reveals a different pattern and level of state intervention. The thesis concludes with a comparative review of the findings of the case studies within a discussion centred on the arguments presented in Chapter 2. Topics arising include the state's differential support for the range of activities involved in innovation, the location of state-funded R&D, the encouragement of supplier-user contact, and the difficulties raised in adoption and diffusion.

Full textAbstract:
Additive manufacturing processes, which utilize selective deposition of material rather than traditional subtractive methods, are very promising due to their ability to build complex, highly specific geometries in short periods of time. Three-dimensional direct inkjet printing is a relatively new additive process that promises to be more efficient, scalable, and financially feasible than others. Due to its novelty, however, numerous technical challenges remain to be overcome before it can attain widespread use. This thesis identifies those challenges and finds that material limitations are the most critical at this point. In the case of deposition of high viscosity polymers, for example, it is found that droplet formation is a limiting factor.
Acoustic resonance jetting, a technology recently developed at Georgia Institute of Technology, may have the potential to address this limitation because it generates droplets using a physical mechanism different from those currently in use. This process focuses ultrasonic waves using cavity resonances to form a standing wave with high pressure gradients near the orifice of the nozzle, thereby ejecting droplets periodically. This thesis reports initial exploratory testing of this technologys performance with various material and process parameters. In addition, analytical and numerical analyses of the physical phenomena are presented. Results show that, while the pressures generated by the system are significant, energy losses due to viscous friction within the nozzle may prove to be prohibitive. This thesis identifies and begins evaluation of many of the process variables, providing a strong basis for continued investigation of this technology.
