Kilpailuetu kansainvälistyvässä monikanavaisessa DIY-kaupassa

Tämän tapaustutkimuksen tavoitteena oli selvittää esimerkkiyrityksen kilpailuetu ympäristössä, jossa kilpailu kansainvälistyy ja monikanavaistuu. Tutkittava yritys on rautakauppa-alan johtava brändi Suomessa. Yritys on tutkimuksen tekemisen aikana ostettu osaksi toimialan Pohjoismaiden suurinta verkkokauppakonsernia. Kvalitatiivinen tutkimus suoritettiin tapaustutkimuksena, johon kuului osana kvantitatiivinen asiakaskysely. Tutkittavalla yrityksellä on verkkokaupan lisäksi kaksi showroom-tyyppistä myymälää, joten asiakaskysely suoritettiin kahdessa osassa erikseen myymälän ja verkkokaupan osalta. Tutkimuksen teoriaosuudessa käsiteltiin tärkeimmät kilpailustrategian teoriat alkaen M.E.Porterin kilpailuetuteoriasta päätyen Kimin ja Mauborgnen Sinisen meren strategiaan. Tutkimuksen tuloksena selvisi, että yrityksellä ei ole selkeätä kilpailuetua. Uuden omistajan myötä on mahdollisuus rakentaa kestävä kilpailuetu. Tutkimustuloksena muodostui myös näkemys, miten yrityksen strategista suunnittelua pitäisi kehittää sekä muodostui ehdotus jatkotutkimukselle. Tutkimuksen pohjalta rakentui malli monikanavaisen DIY- kaupan arvoketjusta ja kehitysehdotus esimerkkiyrityksen arvoketjun kehittämisestä.

Design and implementation of a web based shop floor control system to maintain schedule feasibility in a dynamic job shop environment

The effective control of production activities in dynamic job shop with predetermined resource allocation for all the jobs entering the system is a unique manufacturing environment, which exists in the manufacturing industry. In this thesis a framework for an Internet based real time shop floor control system for such a dynamic job shop environment is introduced. The system aims to maintain the schedule feasibility of all the jobs entering the manufacturing system under any circumstance. The system is capable of deciding how often the manufacturing activities should be monitored to check for control decisions that need to be taken on the shop floor. The system will provide the decision maker real time notification to enable him to generate feasible alternate solutions in case a disturbance occurs on the shop floor. The control system is also capable of providing the customer with real time access to the status of the jobs on the shop floor. The communication between the controller, the user and the customer is through web based user friendly GUI. The proposed control system architecture and the interface for the communication system have been designed, developed and implemented.

A framework for monitoring and runtime recovery of web service-based applications

Service provisioning is a challenging research area for the design and implementation of autonomic service-oriented software systems. It includes automated QoS management for such systems and their applications. Monitoring, Diagnosis and Repair are three key features of QoS management. This work presents a self-healing Web service-based framework that manages QoS degradation at runtime. Our approach is based on proxies. Proxies act on meta-level communications and extend the HTTP envelope of the exchanged messages with QoS-related parameter values. QoS Data are filtered over time and analysed using statistical functions and the Hidden Markov Model. Detected QoS degradations are handled with proxies. We experienced our framework using an orchestrated electronic shop application (FoodShop).

Iis--integrated Interactome System: A Web-based Platform For The Annotation, Analysis And Visualization Of Protein-metabolite-gene-drug Interactions By Integrating A Variety Of Data Sources And Tools.

High-throughput screening of physical, genetic and chemical-genetic interactions brings important perspectives in the Systems Biology field, as the analysis of these interactions provides new insights into protein/gene function, cellular metabolic variations and the validation of therapeutic targets and drug design. However, such analysis depends on a pipeline connecting different tools that can automatically integrate data from diverse sources and result in a more comprehensive dataset that can be properly interpreted. We describe here the Integrated Interactome System (IIS), an integrative platform with a web-based interface for the annotation, analysis and visualization of the interaction profiles of proteins/genes, metabolites and drugs of interest. IIS works in four connected modules: (i) Submission module, which receives raw data derived from Sanger sequencing (e.g. two-hybrid system); (ii) Search module, which enables the user to search for the processed reads to be assembled into contigs/singlets, or for lists of proteins/genes, metabolites and drugs of interest, and add them to the project; (iii) Annotation module, which assigns annotations from several databases for the contigs/singlets or lists of proteins/genes, generating tables with automatic annotation that can be manually curated; and (iv) Interactome module, which maps the contigs/singlets or the uploaded lists to entries in our integrated database, building networks that gather novel identified interactions, protein and metabolite expression/concentration levels, subcellular localization and computed topological metrics, GO biological processes and KEGG pathways enrichment. This module generates a XGMML file that can be imported into Cytoscape or be visualized directly on the web. We have developed IIS by the integration of diverse databases following the need of appropriate tools for a systematic analysis of physical, genetic and chemical-genetic interactions. IIS was validated with yeast two-hybrid, proteomics and metabolomics datasets, but it is also extendable to other datasets. IIS is freely available online at: http://www.lge.ibi.unicamp.br/lnbio/IIS/.

Acessibilidade dos sítios web dos governos estaduais brasileiros: uma análise quantitativa entre 1996 e 2007

A utilização da web para a disponibilização de informações e serviços de órgãos governamentais para os cidadãos tem se tornado cada vez mais expressiva. Assim, a garantia de que esses conteúdos e serviços possam ser acessíveis a qualquer cidadão é imprescindível, independentemente de necessidades especiais ou de quaisquer outras barreiras. No Brasil, o Decreto-Lei nº5.296/2004 determinou que todos os órgãos governamentais deveriam adaptar seus sítios na web de acordo com critérios de acessibilidade até dezembro de 2005. Com o objetivo de verificar a evolução da acessibilidade ao longo dos anos e como foi o impacto dessa legislação, este artigo analisa a acessibilidade dos sítios dos governos estaduais brasileiros por meio de amostras coletadas entre 1996 e 2007. Foram efetuadas análises por meio de métricas, obtidas por avaliações com ferramentas automáticas. Os resultados indicam que a legislação teve pouco impacto para a melhoria real da acessibilidade dos sítios no período indicado, com uma melhora somente em 2007. Verifica-se que se faz necessário adotar políticas públicas mais efetivas para que as pessoas com necessidades especiais tenham os seus direitos para acesso a informações e aos serviços públicos na web assegurados mais amplamente.

A oferta de serviços de informação por situação de vida em sítios Web de bibliotecas virtuais: em busca da qualidade no atendimento

With the advent and development of technology, mainly in the Internet, more and more electronic services are being offered to customers in all areas of business, especially in the offering of information services, as in virtual libraries. This article proposes a new opportunity to provide services to virtual libraries customers, presenting a methodology for the implementation of electronic services oriented by these customers' life situations. Through analytical observations of some national virtual libraries sites, it could be identified that the offer of services considering life situations and relationship interest situations can promote the service to their customers, providing greater satisfaction and, consequently, improving quality in the offer of information services. The visits to those sites and the critical analysis of the data collected during these visits, supported by bibliographic researches results, have enabled the description of this methodology, concluding that the provision of services on an isolated way or in accordance with the user's profile on sites of virtual libraries is not always enough to ensure the attendance to the needs and expectations of its customers, which suggests the offering of these services considering life situations and relationship interest situations as a complement that adds value to the business of virtual library. This becomes relevant when indicates new opportunities to provide virtual libraries services with quality, serving as a guide to the information providers managers, enabling the offering of new means to access information services by such customers, looking for pro - activity and services integration, in order to solve definitely real problems.

The International LAM Registry: A Component of an Innovative Web-Based Clinician, Researcher, and Patient-Driven Rare Disease Research Platform

Background: A relative friability to capture a sufficiently large patient population in any one geographic location has traditionally limited research into rare diseases. Methods and Results: Clinicians interested in the rare disease lymphangioleiomyomatosis (LAM) have worked with the LAM Treatment Alliance, the MIT Media Lab, and Clozure Associates to cooperate in the design of a state-of-the-art data coordination platform that can be used for clinical trials and other research focused on the global LAM patient population. This platform is a component of a set of web-based resources, including a patient self-report data portal, aimed at accelerating research in rare diseases in a rigorous fashion. Conclusions: Collaboration between clinicians, researchers, advocacy groups, and patients can create essential community resource infrastructure to accelerate rare disease research. The International LAM Registry is an example of such an effort.

Exceptional times for the dynamical discrete web

The dynamical discrete web (DyDW), introduced in the recent work of Howitt and Warren, is a system of coalescing simple symmetric one-dimensional random walks which evolve in an extra continuous dynamical time parameter tau. The evolution is by independent updating of the underlying Bernoulli variables indexed by discrete space-time that define the discrete web at any fixed tau. In this paper, we study the existence of exceptional (random) values of tau where the paths of the web do not behave like usual random walks and the Hausdorff dimension of the set of such exceptional tau. Our results are motivated by those about exceptional times for dynamical percolation in high dimension by Haggstrom, Peres and Steif, and in dimension two by Schramm and Steif. The exceptional behavior of the walks in the DyDW is rather different from the situation for the dynamical random walks of Benjamini, Haggstrom, Peres and Steif. For example, we prove that the walk from the origin S(0)(tau) violates the law of the iterated logarithm (LIL) on a set of tau of Hausdorff dimension one. We also discuss how these and other results should extend to the dynamical Brownian web, the natural scaling limit of the DyDW. (C) 2009 Elsevier B.V. All rights reserved.
