A prestação de serviços de logística integrada na indústria automobilística no Brasil: em busca de alianças logísticas estratégicas. / Providing integrated logistics services to the automotive industry in Brazil: the quest for strategic logistics alliances.Léo Tadeu Robles 26 March 2001 (has links)
O estudo aborda as características de relacionamento entre empresas montadoras e operadores logísticos no Brasil, tendo em vista o caráter estratégico da prestação de serviços de logística integrada na indústria automobilística, setor que vem apresentando uma transformação muito grande em suas práticas e organização. O foco de análise é a logística de suprimento em montadoras de automóveis, não se abordando a distribuição de veículos prontos. O processo de globalização tem exigido a reestruturação das empresas para sua sobrevivência e desenvolvimento, a busca de vantagem competitiva, pela incorporação a seus produtos, da cadeia de valor dos clientes, e, no relacionamento interempresarial, novas formas de administração de suas cadeias de suprimentos. Os serviços de logística se mostram mais abrangentes, na estratégia e processo produtivos, numa nova caracterização da atuação de operadores logísticos. Na sua terceirização, tendência firme que se constatou, teoricamente, poderiam se apresentar alianças estratégicas entre empresas. As características de relacionamento nessa direção são abordadas nesta tese. O estudo foi conduzido com base em fontes secundárias e pela realização de entrevistas junto a montadoras e operadores logísticos. Metodologicamente, adotou-se o estudo de multicasos na identificação de arranjos institucionais da operação da logística por operadores especializados. Foi identificado um ambiente em transição, em que a terceirização é um fato, com operadores logísticos, assumindo, cada vez mais, parcelas importantes das atividades dos contratantes. No entanto, o relacionamento está longe de caracterizar verdadeiras alianças estratégicas, apresentando-se uma interação dinâmica e, muitas vezes contraditória, entre as empresas. A consciência mútua das interdependências, aceitação e entendimento de interesses individuais, a serem conciliados em alianças estratégicas, com o objetivo comum de melhor condição competitiva e compartilhamento justo de riscos, custos e recompensas, podem ser fundamentais na implantação de novas formas de produção na indústria e na adoção de operadores logísticos únicos. / This study analyses the relationship among automotive industries and third party logistics (3PL) providers in Brazil, regarding the strategic aspect of the integrated logistics service in that industry, which is showing a remarkable changing in its organization and production practices. This analysis focuses the inbound logistic in car assembling plants. The globalization process requires firms restructure to enable survival and development, the search for competitive advantages, reflecting in their products their clients value chain and, in the relationship among firms, innovative ways of supply chain management. Logistics services assume a broader scope in the production process and in the company strategy, reflecting their providing by 3PL firms in a new way. In this outsourcing, theoretically, strategic alliances among firms could take place. The relationships characteristics towards this direction are analyzed in this thesis. The study used secondary sources and interviews were conducted with automotive and logistic services providers executives. For identifying institutional arrangements in logistics services providing industry, the basic methodology adopted was multicase studies. This work identifies a transition environment with outsourcing as a fact and logistics providers increasingly assuming relevant portions of the automotive industry activities. Nevertheless, their relationships are far from actual strategic alliances, occurring a dynamic and, many times, contradictory interaction among the firms. Consciousness of mutual interdependence, agreement and understanding of individual interests to be conciliated for the achievement of the common objective of better competitive condition and fair risks, costs and rewards sharing are needed. This could be a sound basis for the new production ways and define solids fundamentals for the new trend of full logistic provider implementations, already seen in the industry.

Emerging Security Threats in Modern Digital Computing Systems: A Power Management PerspectiveShridevi, Rajesh Jayashankara 01 May 2019 (has links)
Design of computing systems — from pocket-sized smart phones to massive cloud based data-centers — have one common daunting challenge : minimizing the power consumption. In this effort, power management sector is undergoing a rapid and profound transformation to promote clean and energy proportional computing. At the hardware end of system design, there is proliferation of specialized, feature rich and complex power management hardware components. Similarly, in the software design layer complex power management suites are growing rapidly. Concurrent to this development, there has been an upsurge in the integration of third-party components to counter the pressures of shorter time-to-market. These trends collectively raise serious concerns about trust and security of power management solutions.
In recent times, problems such as overheating, performance degradation and poor battery life, have dogged the mobile devices market, including the infamous recall of Samsung Note 7. Power outage in the data-center of a major airline left innumerable passengers stranded, with thousands of canceled flights costing over 100 million dollars. This research examines whether such events of unintentional reliability failure, can be replicated using targeted attacks by exploiting the security loopholes in the complex power management infrastructure of a computing system.
At its core, this research answers an imminent research question: How can system designers ensure secure and reliable operation of third-party power management units? Specifically, this work investigates possible attack vectors, and novel non-invasive detection and defense mechanisms to safeguard system against malicious power attacks. By a joint exploration of the threat model and techniques to seamlessly detect and protect against power attacks, this project can have a lasting impact, by enabling the design of secure and cost-effective next generation hardware platforms.

Provider recommendation based on client-perceived performanceThio, Niko January 2009 (has links)
In recent years the service-oriented design paradigm has enabled applications to be built by incorporating third party services. With the increasing popularity of this new paradigm, many companies and organizations have started to adopt this technology, which has resulted in an increase of the number and variety of third party providers. With the vast improvement of global networking infrastructure, a large number of providers offer their services for worldwide clients. As a result, clients are often presented with a number of providers that offer services with the same or similar functionalities, but differ in terms of non-functional attributes (or Quality of Service – QoS), such as performance. In this environment, the role of provider recommendation has become more important - in assisting clients in choosing the provider that meets their QoS requirement. / In this thesis we focus on provider recommendation based on one of the most important QoS attributes – performance. Specifically, we investigate client-perceived performance, which is the application-level performance measured at the client-side every time the client invokes the service. This performance metric has the advantage of accurately representing client experience, compared to the widely used server-side metrics in the current frameworks (e.g. Service Level Agreement or SLA in Web Services context). As a result, provider recommendation based on this metric will be favourable from the client’s point of view. / In this thesis we address two key research challenges related to provider recommendation based on client-perceived performance - performance assessment and performance prediction. We begin by identifying heterogeneity factors that affect client-perceived performance among clients in a global Internet environment. We then perform extensive real-world experiments to evaluate the significance of each factor to the client-perceived performance. / From our finding on heterogeneity factors, we then develop a performance estimation technique to address performance assessment for cases where direct measurements are unavailable. This technique is based on the generalization concept, i.e. estimating performance based on the measurement gathered by similar clients. A two-stage grouping scheme based on the heterogeneity factors we identified earlier is proposed to address the problem of determining client similarity. We then develop an estimation algorithm and validate it using synthetic data, as well as real world datasets. / With regard to performance prediction, we focus on the medium-term prediction aspect to address the needs of the emerging technology requirements: distinguishing providers based on medium-term (e.g. one to seven days) performance. Such applications are found when the providers require subscription from their clients to access the service. Another situation where the medium-term prediction is important is in temporal-aware selection: the providers need to be differentiated, based on the expected performance of a particular time interval (e.g. during business hours). We investigate the applicability of classical time series prediction methods: ARIMA and exponential smoothing, as well as their seasonal counterparts – seasonal ARIMA and Holt-Winters. Our results show that these existing models lack the ability to capture the important characteristics of client-perceived performance, thus producing poor medium-term prediction. We then develop a medium-term prediction method that is specifically designed to account for the key characteristics of a client-perceived performance series, and to show that our prediction methods produce higher accuracy for medium-term prediction compared to the existing methods. / In order to demonstrate the applicability of our solution in practice, we developed a provider recommendation framework based on client-perceived performance (named PROPPER), which utilizes our findings on performance assessment and prediction. We formulated the recommendation algorithm and evaluated it through a mirror selection case study. It is shown that our framework produces better outcomes in most cases, compared to country-based or geographic distance-based selection schemes, which are the current approach of mirror selection nowadays.

Third-Party Disability in Spouses of Older People with Hearing ImpairmentNerina Scarinci Unknown Date (has links)
Hearing impairment is the most common communication disability in older people. The wide-ranging impact of hearing impairment on communication means that not only does the person with hearing impairment experience the consequences but also his or her frequent communication partners. This thesis investigates the impact of hearing impairment on spouses and uses the World Health Organization’s term “third-party disability.” Third-party disability is defined as the impairments, activity limitations, and participation restrictions experienced by the family due to the health condition of their significant other, and was identified by the World Health Organization as an area for future development and application of the International Classification of Functioning, Disability and Health (ICF). Despite a number of studies previously published on the effect of hearing impairment on family members, including younger couples and carers, there remain substantial gaps in knowledge and understanding of the difficulties specifically relating to older people and factors associated with third-party hearing disability. This thesis focuses on the third-party disability experienced by normally hearing spouses (termed the “spouses” in this thesis) of older people with hearing impairment (termed the “partners” in this thesis). To add empirical data to the body of research, this series of studies first explored the lived experience of spouses of older people with hearing impairment in a qualitative study, then identified the ICF domains and categories that described third-party hearing disability, described the extent of third-party hearing disability in this population, modelled the contribution of factors to third-party hearing disability, and developed and psychometrically tested a scale to measure the third-party disability of spouses of older people with hearing impairment. Studies conducted within this thesis were therefore completed in two phases. Ten spouses of older people with hearing impairment participated in the first qualitative phase, consisting of semi-structured in-depth interviews. Results of this study showed that spouses experience a number of effects as a result of their partners’ hearing impairment including: (1) the broad ranging effects of the hearing impairment on the spouses’ everyday lives; (2) the spouses’ need to constantly adapt to their partners’ hearing impairment; (3) the effect of acceptance of the hearing impairment on the spouse; and (4) the impact of ageing and retirement. Findings were then linked to the ICF to identify the most typical and relevant domains and categories of the ICF for spouses of older people with hearing impairment. The majority of themes were able to be linked to the ICF, with most linking to codes in the activities and participation component. A number of contextual factors were also identified that influenced the spouses’ third-party disability. In the second phase, a further 100 older couples affected by hearing impairment participated in a quantitative face-to-face survey to describe the nature and degree of third-party disability in spouses, and to examine factors associated with third-party hearing disability. Concepts identified in the first qualitative study were used to formulate a 36-item tool for measuring spouses’ third-party hearing disability, namely the Significant Other Scale for Hearing Disability (SOS-HEAR). The majority of spouses in this study (98%) reported some degree of third-party hearing disability on at least one item of the SOS-HEAR. Communication difficulties between the couple were the central source of stress reported by spouses, followed by emotional problems in the spouse. Three factors were found to be significantly associated with greater third-party hearing disability: (1) lower relationship satisfaction as described by spouses; (2) a larger spouse-partner age difference; and (3) greater hearing disability in the hearing impaired partner as perceived by the spouse. The scaling properties of the SOS-HEAR were then examined, with a revised 27-item questionnaire found to be a reliable means of measuring older spouses’ third-party hearing disability. Use of the SOS-HEAR is proposed as a means of identifying spouses of older people with hearing impairment in need of intervention. If spouses are identified as experiencing third-party hearing disability, health professionals are then in a position to facilitate discussions with the couple about the impact of the hearing loss on their daily functioning. The inclusion of spouses in rehabilitation takes into account the needs of both members of the couple such that they become partners in rehabilitation. In summary, this research has shown that hearing impairment in older people has an effect on the spouse, as they too experience situations of communication activity limitations and participation restrictions. It is clear that the lives of participants in this study were considerably affected as a result of their partners’ hearing impairment, with spouses reporting a wide variety of stresses involving lifestyle changes, communication difficulties, and emotional consequences. This series of studies has highlighted the potentially important role of family-centred intervention in rehabilitation for older adults with hearing impairment, and strongly suggests the need for increased inclusion of spouses and significant others in the rehabilitation process.

Value-Added Services in Third-Party Logistics : A study from the TPL providers’ perspective about value-added service development, driving forces and barriersAtkacuna, Ilze, Furlan, Karolina January 2009 (has links)
Competition in the logistics service industry has constantly increased over the last decades which has lead to the traditional services offered by third-party logistics (TPL) providers becoming commodities and no longer offering attractive profit margins. When the company’s core product becomes a commodity, the company’s performance of supplementary services becomes vital for competitive advantage. The term “value-added service” is defined as a service adding extra feature, form or functions to the basic service and stands for all types of activities which are not directly based on services traditionally offered by TPL providers, i.e., transportation and warehousing. The term value-added service is mainly used in the logistics literature while supplementary service is used in the service management literature. Although value-added services can offer obvious advantages in form of customer lock-in and improved competitive advantage, such services are still offered at a low level and there is much space for development. The purpose of this thesis is to analyse how TPL firms develop value-added services and to investigate what the driving forces and barriers for developing and providing such services are. In the frame of reference, literature within service management, outsourcing, third-party logistics, value-added services, innovation and learning have been used. In the thesis, an inductive research approach is used and qualitative study has been carried out by applying multiple case studies as a research strategy. The empirical material is gathered from three TPL providers: Bring Logistics Solutions, Aditro Logistics and Schenker Logistics. Data was collected through several interviews conducted at the three target companies and the findings have been analysed using the existing theory stated in the frame of reference. The main conclusions from analysing the development process of value-added services are that this process in most cases is initiated by customer request and that development of value-added service can occur both in the beginning or during an ongoing relationship, though a lack of information about a customer’s business in the beginning of the relationship can hinder the TPL provider to develop value-added services. Apart from the TPL provider and the customer, firms such as IT companies, transport suppliers and other companies can be involved in the development process. No formal innovation process is applied for developing value-added services. The main driving force behind value-added services is meeting customer demands. Lack of proactiveness from the TPL provider’s side can be a barrier for developing value-added services, as well as problems with achieving successful organizational learning. The difficulty for the TPL firm to coordinate offering so many different services can be also seen as a barrier.

The introduction of safe and sustainable agriculture certification : a case study of cherry growers in the Southern Interior of British ColumbiaArdiel, Jennifer 05 1900 (has links)
GlobalGAP (previously EurepGAP) is a voluntary business-to-business standard for food audit that has recently achieved the greatest acceptance worldwide (Campbell, Lawrence & Smith 2006) boasting implementation numbers of over 80,000 farms in 80 countries. Compliance with the standard is verified by means of the third party certification (TPC) audit, and is designed to (GlobalGAP 2008) assure European retailers that exporting producers have met their criteria for safe and sustainable agriculture (GlobalGAP 2007b). In 2004, cherry growers in the Southern Interior of British Columbia became the first GlobalGAP certified producers in Canada. This novelty afforded a unique opportunity to observe the introduction of the standard in an industrialized country with well-established regulations and where the capacity of producers to undertake the process was relatively high. A qualitative methodology was used in case studies of two communities to inductively study the implementation of ‘safe and sustainable agriculture’ certification and generate relevant research questions for deeper examination. Sensitizing concepts emerging from observations of the TPC audits (n = 20) evolved into two primary research objectives; 1) to understand the practical application and diffusion of a TPC standard and 2) to explore the efficacy of the TPC standard as a mechanism to promote sustainable agriculture within certain pre-existing contexts. Forty-four follow up interviews were conducted with growers that chose to certify (n = 24), those that did not (n = 14), and other key actors (n = 3). This thesis examines the research objectives over three chapters. The introduction provides the local and global context along with a review of GlobalGAP, agri-food governance and the role of private certification and retailer power. Chapter two presents the technological and sociological factors that influenced the stages of the diffusion of GlobalGAP TPC and compares these factors and outcomes to the technological and sociological components of sustainable agriculture. In the conclusion, policy strategies are offered to maximize the potential for this tool to promote sustainable agriculture along with suggestions for future research on the topic.

GAP i efterfrågan : En undersökning om efterfrågan på miljövänliga transporterRehnström, Simon, Almlöf, Linnea January 2013 (has links)
Purpose: Corporations today see a greater responsibility towards society regarding the environmental impact of their actions, using available transportation options that are more eco-friendly can reduce this impact significantly. Martinsen and Björklund (2012) identifies a set of gaps between supply and demand of green logistics services. This paper aims to address what it is that affects the demand for these alternative solutions and what could be done to increase the usage of them, thereby decreasing this gap. Design/methodology/approach: A quantitative study with six Logistics Service Providers (LSP) and 24 companies that purchase transportation services, all operating in Sweden. Data is collected through semi-structured telephone interviews with people responsible for the purchasing of transports as well as key account managers within the service providing companies. Findings: Just as the LSP’s interviewed in this paper thought, the main focus of the transport buying companies are the costs. Therefore paying extra only to benefit the environment and not the economy of the company is not something a lot of companies are prepared to do at this time. However there are solutions such as intermodality which are highly demanded, these are often both cost effective and more environmentally friendly, the problem as many companies see it, is that the rail network needs to expand to be able to cover bigger areas and increase the capacity. Research limitations/implications: The research paper focuses on companies operating on the Swedish market, for that reason findings cannot be generalized to other countries and sectors. Practical implications: Findings can be used by LSP’s and political decision making parties to get a better understanding of the demand for this type of services and what is perceived as important by the customers. Originality/value: There is a lack of earlier studies that mainly focus on the demand of more environmentally friendly transport services. Therefore a study of this kind is important to create an understanding and thereby improve the overall situation on the market in terms of environmental sustainability.
