Huang, Chun-shyen 06 August 2007 (has links)
BOF slag is a co-product generated from Basic Oxygen steelmaking process with annual production of 1.3 million tons approx. Because of its unique physical and chemical properties, it was considered as waste in the past and dumped to the ocean. After research and development, the BOF slag was used as sea-shore embankment and landfill material. Then it was registered as a product and was further used as land filler of temporary roads and parking lots. For now, BOF slag can be used as engineering materials such as asphalt concrete aggregates and Controlled Low Strength Material. Advancing waste recycling to promote resources optimization is an essential factor to industrial sustainable development. It also meets the global trends of sustainable use of resources and sustainable development of economy and society. Investigating the process of BOF slag resourcilization, it is concluded that the center of the development frame of recycled products is waste resourcilization. The steps to completely solve pollution problems including: input of human and natural resources, basic research and development, and finally converting waste into products. Meanwhile, governmental regulations must not be violated. Relevant regulations, domestic and international experiences and practices, and market investigation must be considered to confirm market need and opportunities for development. After the above are finished, the work team can be formed to start research and development. The recycled product development process can be divided into 7 major stages, including basic properties analysis, selection of application direction, technological research and evaluation, economical feasibility analysis, trial production and market testing, certification and specification modification, commercialization and promotion.

The Process for Adopting Technology in Ontario Municipalities and the Implications for Innovation in Development

Riemer, Mary Rowntree Watt Bachem January 2014 (has links)
The purpose of this thesis is to provide a stepping stone for technological innovation in the development control process. As a foundational piece of research on this topic, it leverages classic technology adoption theory alongside an investigation of how municipalities adopt innovation for tools of planning, such as geographic information systems. This thesis provides a qualitative analysis of opportunities and barriers to the potential for the adoption of an online development control process, investigating satisfaction with the current process, perceptions on potential aspects of innovation within the process and willingness to adopt. The survey conducted revealed a gap between perceived versus actual satisfaction with the current process, conflicting views between municipal and consulting planners, and a strong overall interest the ability to submit development control applications online. This paper found that perceived barriers such as complacency with the current system can be overcome when confronted by innovation; however barriers including capital cost investment are real and require further consideration in the adoption process. Findings from this thesis point to a strong willingness for innovation of the process, especially the conception of an intuitive online development control process.

Design and the Conversational Self

Shumack, Kaye, n/a January 2009 (has links)
This thesis sets out a theoretical premise for design research into the space of the designer, working inside the design system or context. The designer is understood as actor, as active agency looking inwards in a comprehensive way to examine where ideas are located and then, how these new insights or perspective might be meaningfully introduced. In order to develop this research, personal journal writing is employed as to develop an understanding about how the designer/actor can actively engage with being at once participant, and observer, of their own design practice. A series of design case studies are carried out, where the role of the designer as actor is critically examined through forms of personal journal writing. What this entails is the establishment of a form of autopoetic system for writing in several voices of the self, and self-as-other working in, and through as design project case studies. I critically evaluate these journal case studies to inform my understanding about the design of dialogic visual communication, where multiple perspectives of self, and self-as-other may be interwoven into the visual design artifact. As a result of conducting this research, I propose the existence of what I term the 'conversational self' as a means for developing new knowledge and knowing through conversational story-telling as design research. My research introduces the 'conversational self' as a generalisable theory for design research which addresses the ways in which the designer might effectively engage with the workings of personal tools and patterns of practice, thus building greater objectivity through recognition of local contexts, and the role of the designer as actor and as a situated self within the design process. My research findings describe a space for the 'conversational self' as the coming together of three linked knowledge systems for creation and learning. I describe this theory as 'agency-centred' design for research about design and experiential knowledge contexts through research into the development of project case studies where individual styles and approaches to learning and thinking which are recognised and valued as implicit tools of and for design practice. Firstly, the conversational journal writing format which I develop situates the designer/ researcher as both participant and observer within their design decision-making. As a result of the uses of the journal format as a practice-based research methodology through case studies, I observe the effect of producing what I term an 'autopoetic' (Maturana and Varela) self-producing system, which enables me to introduce both rational and intuitive content that works in my journal through a range of thinking styles and journal forms. My research strategy involves the writing of several concurrent and interacting levels of internal conversation across 'I', 'You', 'Me' and 'We' as parallel and interactive experiential voices of self through uses of a journal format where a range of experiences are documented as design project narratives. The conversational contexts which this approach offers provide a means for introducing multiple perspectives from self, and selfas- other (as designer, author, subject, agent, person) to explore topics and social knowledge themes through a range of creative conversational learning contexts (Pask, Glanville). In the course of developing this approach I draw on theories about personal constructs (Kelly, Thomas and Harri-Augustein); the self as forms as agency (Archer); about experiential learning and knowledge creation through learning conversations (Baker, Jensen and Kolb) ; and social knowledge as networks, flows and exchange processes (Boisot). Secondly, as a finding from my usage of this journal format, I propose the workings of what I describe as my 'unity of self' system construct as an enabling and generative system for working with social knowledge and the 'self' as forms of agency through internal conversations. Margaret Archer's theory describes the social self as forms of causal agency active in everyday social and experiential contexts. In my case studies I trace the internal dynamics and interactions of 'voices' of self in the journal text, which I evaluate as the workings of conversational levels and layers which engage with a range of details and perspectives for each project using written and non-verbal forms. The design case study projects each describes a particular context for design practice; including institutional, corporate, experimental, and personal design projects. In using this methodology for journal writing, I show how I am able to explore the social interplays of personal/public and individual/collective frameworks for design practice contexts. Thirdly, through my evaluations of the design project case study journals, I observe the emergence of topics and themes in each project around my understanding of the role of context for defining the social and experiential 'materials' (Schon) of the situation. The topics noted from conversations in design case inform what I term my 'contextual field' as the third learning system in my findings from this research. This 'contextual field' is a kind of topical map which provides signposts for working with social and experiential contexts, to design 'ecological narratives' (Krippendorff) as forms of language which are crafted as intentional and strategic design approaches, as responses to the research process of internal reflection about the materials of the situation (Schon) Through usage with my journal format, and unity of self construct, my contextual field topical map provides a framework for developing topics and themes for internal conversations to inform my design production in both 'service' and 'hand' craft project contexts. What results are rich use case studies documented as forms of conversational story-telling where new knowledge emerges as questions and possibilities around the design of visual artifacts and service contexts.

Improvement of Work Process in a Global Verification Team : A case study at VSM

Yuan, Wenjing January 2016 (has links)
With increasing demands from customers, companies face the challenges of shortening the new product development (NPD) period, reducing development cost and increasing development efficiency. High quality and efficiency of NPD can increase the chance for companies to be competitive on the market. Forming up cross-functional teams becomes a popular way of maximizing the knowledge then increase the development quality and efficiency. However, it is challenging to integrate the resources from different functions and even more challenging when the resources are from different countries. To overcome the integration challenges can increase the efficiency of NPD projects therefore finally win global market shares. This study’s purpose is to identify and analyze integration challenges experienced by a verification team involved in global NPD and to suggest how those challenges can be managed by answering two research questions: 1) What are the integration challenges with the current work process encountered by the global verification team? 2) How can the integration challenges be met in the improved work process? The case study is used as the research method in order to get deep insight of the challenges that a global verification team faces. VSM Group AB, an international leading sewing company is selected as the case company.  The case team, a global verification team locates both in Sweden and China, plays the role of verification work within NPD process. The case team verifies the design and new products in the process.  Through interviews, observation and literature reviews, the challenges in this global verification team are identified. It is found that the case team needs to overcome language barriers, culture difference, task planning and formalization and standardization on work performance during integration. Based on the investigations, a set of solutions are proposed in the end to meet the challenges. These solutions are an improved work process, work performance system, training program and uniformed documentation. These proposals are inspired by the integration mechanisms such as formalization and standardization, special reports etc and then fit them into the case team context. By simulation and evaluation the solutions within the global verification team, the feedback on the proposals helped for improvement. This case study at VSM is an empirical example of implementation of integration mechanisms into a real life context.

AUTOMATION OF A CLOUD HOSTED APPLICATION : Performance, Automated Testing, Cloud Computing / AUTOMATION OF A CLOUD HOSTED APPLICATION : Performance, Automated Testing, Cloud Computing

Penmetsa, Jyothi Spandana January 2016 (has links)
Context: Software testing is the process of assessing quality of a software product to determine whether it matches with the existing requirements of the customer or not. Software testing is one of the “Verification and Validation,” or V&V, software practices. The two basic techniques of software testing are Black-box testing and White box testing. Black-box testing focuses solely on the outputs generated in response to the inputs supplied neglecting the internal components of the software. Whereas, White-box testing focuses on the internal mechanism of the software of any application. To explore the feasibility of black-box and white-box testing under a given set of conditions, a proper test automation framework needs to be deployed. Automation is deployed in order to reduce the manual effort and to perform testing continuously, thereby increasing the quality of the product. Objectives: In this research, cloud hosted application is automated using TestComplete tool. The objective of this thesis is to verify the functionality of cloud application such as test appliance library through automation and to measure the impact of the automation on release cycles of the organisation. Methods: Here automation is implemented using scrum methodology which is an agile development software process. Using scrum methodology, the product with working software can be delivered to the customers incrementally and empirically with updating functionalities in it. Test appliance library functionality is verified deploying testing device thereby keeping track of automatic software downloads into the testing device and licenses updating in the testing device. Results: Automation of test appliance functionality of cloud hosted application is made using TestComplete tool and impact of automation on release cycles is found reduced. Through automation of cloud hosted application, nearly 24% of reduction in level of release cycles can be observed thereby reducing the manual effort and increasing the quality of delivery. Conclusion: Automation of a cloud hosted application provides no manual effort thereby utilisation of time can be made effectively and application can be tested continuously increasing the efficiency and / AUTOMATION OF A CLOUD HOSTED APPLICATION

Importância do uso de mock-ups e de técnicas de prototipagem e ferramental rápido no processo de desenvolvimento de produto na indústria automotiva. / Importance of mok-ups and techniques of prototype and rapid tooling application on the process of product development in automotive industry.

Macarrão Junior, Leonardo 20 December 2004 (has links)
O Processo de Desenvolvimento de Produto (PDP) é um processo caro para qualquer empresa, pois são utilizadas muitas horas de mão de obra especializada. Nesta fase são encontrados muitos problemas, dificuldades ou oportunidades de melhoria. Quanto mais cedo forem detectadas estas necessidades, menos onerosas serão as alterações, necessárias para que o produto ou o processo de fabricação em série esteja dentro do planejamento da empresa, considerando prazo, custo, qualidade e design. Este trabalho mostra como a utilização de modelos físicos preliminares - mock-ups e prototipagem rápida podem facilitar o PDP. Suas características principais são reduzir o prazo, identificar precocemente os problemas de projeto, de montagem e também as dificuldades do processo de fabricação. Assim são evitados os altos custos na correção de um eventual problema em uma fase adiantada do projeto, próximo ao início de produção. Muitas vezes o PDP requer várias unidades de uma mesma peça protótipo. Por este motivo, outro aspecto abordado neste trabalho é a utilização de ferramental rápido, que reduz o tempo de fabricação e o custo por unidade protótipo fabricada, permitindo que o produto seja desenvolvido e analisado de uma forma confiável e consistente. É mostrado como o investimento no uso de prototipagem rápida e de ferramental rápido, que é relativamente alto, reduz o risco de encontrar surpresas no início da produção. Desta forma, são apresentados alguns processos de fabricação demock-ups, de prototipagem rápida e de ferramental rápido, acessíveis à maior parte das empresas e aplicáveis não só à indústria automobilística, mas também a outros tipos de indústria. / The Product Development Process (PDP) is an expensive process to any company, because many specialized manpower are required. In this phase, many problems and difficulties are faced but also improvement opportunities are identified. As soon as these requirements are being detected, less onerous these changes will be effective, in order to the serial fabrication process be according to the company planning, considering lead time, cost, quality and design. This job shows how the mock-ups and rapid prototyping utilization make the PDP easily. Their main characteristics are reducing the lead-time, previously identification of the project and assembly problems, and also the process fabrication troubles. This way, high correction costs are avoided in eventual problems in an advanced project phase, next to the start of production. Many times the PDP requires several units of the same prototype part. Due to this reason, another mentioned issue in this job is the rapid tooling utilization, which can reduce the fabrication time and the cost per fabricated prototype unit, also allowing to the product be developed and analyzed in a trusty and consistent way. It is shown how the rapid prototyping and rapid tooling investment, that is relatively high, can reduce the risk to face any surprise in the start of production. This way, some mock-up fabrication, rapid prototyping and rapid tooling processes are presented, which is accessible to most of companies and are applicablenot only to automobile industry but to the other kinds of companies too.

A integração entre tecnologia e produto nas empresas de base tecnológica de São Carlos / Product and technology integration in technology-based firms in São Carlos

Kurumoto, Juliana Sayuri 24 June 2009 (has links)
Inovar não significa apenas dominar uma tecnologia, gerando protótipos e patentes. Precisa-se ir além, introduzir produtos no mercado que façam uso da tecnologia desenvolvida. Um dos desafios, portanto, é garantir a integração entre as tecnologias e o produto desenvolvido, minimizando riscos e maximizando resultados. Os modelos teóricos para descrever a integração apresentam deficiências, discutidas neste trabalho, e há poucos relatos sobre a situação de empresas brasileiras quanto à prática. A revisão bibliográfica, combinada com um estudo de caso, possibilitou a delimitação e descrição dos elementos envolvidos no fenômeno integração tecnologia-produto. Permitiu também identificar dois componentes como fundamentais, denominados de estratégia de sincronização tecnológica e a estratégia de desenvolvimento da inovação. A pesquisa tem por objetivo caracterizar e analisar as estratégias de desenvolvimento da inovação e sincronização tecnológica no contexto dos projetos de produtos inovadores das empresas de base tecnológica filiadas ao Parque Tecnológico de São Carlos. O levantamento (survey) verificou 24 projetos de sucesso, um para cada empresa que participa ou participou do ParqTec, de um total de 35 empresas que projetaram produtos envolvendo hardware e software. As empresas adotam predominantemente a sincronização simultânea e o desenvolvimento da tecnologia origina-se da necessidade de um produto desejado pelo mercado (estratégia top-down). O resultado indica que a grande maioria das empresas não diferencia tecnologia de produto e, portanto, não realiza uma gestão diferenciada e integrada de ambos, o que, segundo a literatura, pode levar a desperdícios de tempo e maior risco na inovação. O trabalho aponta possíveis causas e temas para pesquisas futuras. / Innovation not only master a technology, generating prototypes and patents. We need to go beyond, to introduce products to market that make use of the technology developed. One of the challenges therefore is to ensure the integration of technology and product development in order to minimize risks and maximize the outcome. The theoretical model presents problems of integration, discussed in this work, and there are few reports on the status of national companies in practice. The literature review, combined with a case study, demonstrate the elements involved in technology-product integration phenomenon. It also identified as two key components, called the synchronization strategy and innovation strategy. The research aims to characterize and analyze the innovation and synchronization strategies in the context of innovative product designs of technology-based firms affiliated to the Technological Park of São Carlos. The survey found 24 successful projects for each company that participates or participated in ParqTec or participated in a total of 35 companies that designed products involving hardware and software. Companies adopt predominantly simultaneous synchronization and the technology development originates from the need for a product desired by the market (top-down strategy). The result indicates that the vast majority of companies do not differentiate the product and technology and therefore does not have differentiated and integrated management of both, which, according to the literature, may lead to waste of time and greater risk in innovation. The work suggests possible causes and issues for future research.

A framework supporting the collaboration between the logistics- and the product development process

Andersson, Anna January 2007 (has links)
<p>In the competitive environment of today’s global markets, the demands of customers are increasing. They expect to get the best product at the lowest price with immediate availability. Logistics, including transportation, inventory maintenance, order processing, purchasing, warehousing, materials handling, packaging, customer service standards, and product scheduling must continuously be developed to meet the challenges of the market. The globalization, with longer distances to customers and suppliers, and the progressing trend of outsourcing are examples of why the importance of logistics has increased over the last few years.</p><p>A considerable part of the final product cost is frozen during the early product development phases. In the early phases of the product development process, the cost of making design changes is low compared to making changes later in the product development process. The product development decisions made in the early phases of the product development process have considerable impact on future manufacturing and logistics activities as well.</p><p>The objective of this research project is to develop a framework supporting the collaboration between the logistics- and the product development process. To do this, it has been essential to analyze which parameters influence the efficiency of the logistics process and the interface between the logistics- and the product development process. Also, to investigate how the logistics department can be integrated earlier in the product development process has been of interest. This has been done through both a theoretical review and also through a number of case studies.</p><p>The result and conclusion of this project is a framework that gives support for what to focus on, how to collaborate, in which phases collaboration is meaningful, and which persons need to be involved in the different product development phases. Working as the framework suggests will, hopefully, give closer collaboration between the logistics- and the product development process than without this supportive framework. The expectation of the collaboration is an earlier integration of the logistics department in the product development process and through this influence and increase the efficiency of the logistics process.</p>

Mining Of Text In The Product Development Process

Loh, Han Tong, Menon, Rakesh, Leong, Christopher K. 01 1900 (has links)
In the prevailing world economy, competition is keen and firms need to have an edge over their competitors for profitability and sometimes, even for the survival of the business itself. One way to help achieve this is the capability for rapid product development on a continual basis. However, this rapidity must be accomplished without compromising vital information and feedback that are necessary. The compromise in such information and feedback at the expense of speed may result in counter-productive outcomes, thereby offsetting or even negating whatever profits that could have been derived. New ways, tools and techniques must be found to deliver such information. The widespread availability of databases within the Product Development Process (PDP) facilitates the use of data mining as one of the tools. Thus far, most of the studies on data mining within PDP have emphasised on numerical databases. Studies focusing on textual databases in this context have been relatively few. The research direction is to study real-life cases where textual databases can be mined to obtain valuable information for PDP. One suitable candidate identified for this is “voice of the customer” databases. / Singapore-MIT Alliance (SMA)
