Proposta de um modelo de sistema de apoio à decisão em vendas: uma aplicação / Proposal of decision support system\'s model for sales: an application

Stefanoli, Franklin Seoane 20 March 2003 (has links)
Este trabalho teve por objetivo o desenvolvimento de uma proposta de um modelo de sistema de apoio à decisão em vendas e sua aplicação. O levantamento sobre o perfil das vendas no mercado corporativo - de empresas-para-empresas, as técnicas de vendas, informações necessárias para a realização de uma venda eficiente, tal qual o controle das ações e resultados dos vendedores com a ajuda de relatórios, tudo isso aliado às tecnologias de data warehouse, data mart, OLAP foram essenciais na elaboração de uma proposta de modelo genérico e sua implantação. Esse modelo genérico foi aplicado levando-se em conta uma editora de listas e guias telefônicos hipotética, e foi construído buscando-se suprir os profissionais de vendas com informações que poderão melhorar a efetividade de suas vendas e dar-lhes maior conhecimento sobre seus produtos, clientes, usuários de listas e o mercado como um todo, além de suprir os gerentes de uma ferramenta rápida e confiável de auxílio à análise e coordenação dos esforços de vendas. A possibilidade de visualização rápida, confiável e personalizada das diversas informações permitidas por esse sistema, tal qual o êxito em responder às perguntas de pesquisas apresentadas no trabalho, comprova que essa aplicação poderá ser útil à empresa e em específico aos profissionais de vendas e gerentes tomadores de decisão. / The objective of this study was a development of a decision support system\'s application for sales. Relevant information about business markets and business buying behavior, principles of selling and evaluation models for sales representatives, all of this supported by data warehouse, data mart and OLAP technologies was important to create a generic DSS model as well your application. This generic model was created due to match some information needs of sales professionals from a hypothetic publishing company (yellow page). This system and the information generated by it would improve the effectiveness of sales professionals (sales reps), giving them more information and knowledge about your product, market, customers, users, and offering to sales managers as well decision makers a reliable, fast and interactive tool for sales effort\'s analysis and monitoring. A fast, interactive, reliable and customized visualization of information - characteristics of this system, as well your effectiveness of answering questions presented in the beginning of this study reinforce the utility and applicability of this model in order to satisfy sales professionals, managers and publishing companies information needs.

Vilka effekter har jämförelsesidor givit för konkurrensen på bolånemarknaden : Nationalekonomisk kandidatuppsats

Näslund, Agnes January 2019 (has links)
After the financial crisis, several comparison websites have emerged for private lenders to enable comparison on mortgage terms. The idea behind the comparison pages is that they should be used by the private borrower. On June 1, 2015, a new directive emerged from the Swedish Financial Supervisory Authority to the credit institutes that instead of the list interest, the average interest rate that the lenders offer their customers should be the one published, in order to further increase the transparency of the price. The purpose of this study is to investigate whether competition in the mortgage market has improved after the introduction of the comparison websites and the effects of the increased price transparency. In order to investigate the competition on the mortgage market, the theory of market forms and the Herfindahl-Hirschman Index has been applied. The result of the study shows that the concentration of competition has increased over time. This study also shows that the comparison pages have contributed to increased price transparency that has contributed to consumers information about the market. This study is limited to the Swedish mortgage market. / Efter finanskrisen har flertalet jämförelsesidor uppkommit för att möjliggöra jämförelser av räntor och villkor på bolån. Jämförelsesidor ska förenkla processen att jämföra de olika långivarna. Den 1 juni 2015 kom ett nytt direktiv från finansinspektionen till långivarna att istället för listräntan ska den genomsnittliga räntan som långivarna ger sina kunder vara den som publiceras, för att öka pristransparensen ytterligare. Denna studies syfte är att undersöka hur konkurrensen på bolånemarknaden har förändrats efter jämförelsesidornas tillkomst med HHI-index och konkurrensteori. Teori om marknadsformer och Herfindahl-Hirschman Index att tillämpas för att undersöka konkurrensen. Resultatet av studien visar att koncentrationen av konkurrensen har ökat över tid. Denna studie visar även att jämförelsesidorna har bidragit med ökad pristransparens som har bidragit till konsumenternas information om marknaden. Studien är avgränsad till den svenska bolånemarknaden.

Indexation et interrogation de pages web décomposées en blocs visuels

Faessel, Nicolas 14 June 2011 (has links)
Cette thèse porte sur l'indexation et l'interrogation de pages Web. Dans ce cadre, nous proposons un nouveau modèle : BlockWeb, qui s'appuie sur une décomposition de pages Web en une hiérarchie de blocs visuels. Ce modèle prend en compte, l'importance visuelle de chaque bloc et la perméabilité des blocs au contenu de leurs blocs voisins dans la page. Les avantages de cette décomposition sont multiples en terme d'indexation et d'interrogation. Elle permet notamment d'effectuer une interrogation à une granularité plus fine que la page : les blocs les plus similaires à une requête peuvent être renvoyés à la place de la page complète. Une page est représentée sous forme d'un graphe acyclique orienté dont chaque nœud est associé à un bloc et étiqueté par l'importance de ce bloc et chaque arc est étiqueté la perméabilité du bloc cible au bloc source. Afin de construire ce graphe à partir de la représentation en arbre de blocs d'une page, nous proposons un nouveau langage : XIML (acronyme de XML Indexing Management Language), qui est un langage de règles à la façon de XSLT. Nous avons expérimenté notre modèle sur deux applications distinctes : la recherche du meilleur point d'entrée sur un corpus d'articles de journaux électroniques et l'indexation et la recherche d'images sur un corpus de la campagne d'ImagEval 2006. Nous en présentons les résultats. / This thesis is about indexing and querying Web pages. We propose a new model called BlockWeb, based on the decomposition of Web pages into a hierarchy of visual blocks. This model takes in account the visual importance of each block as well as the permeability of block's content to their neighbor blocks on the page. Splitting up a page into blocks has several advantages in terms of indexing and querying. It allows to query the system with a finer granularity than the whole page: the most similar blocks to the query can be returned instead of the whole page. A page is modeled as a directed acyclic graph, the IP graph, where each node is associated with a block and is labeled by the coefficient of importance of this block and each arc is labeled by the coefficient of permeability of the target node content to the source node content. In order to build this graph from the bloc tree representation of a page, we propose a new language : XIML (acronym for XML Indexing Management Language), a rule based language like XSLT. The model has been assessed on two distinct dataset: finding the best entry point in a dataset of electronic newspaper articles, and images indexing and querying in a dataset drawn from web pages of the ImagEval 2006 campaign. We present the results of these experiments.

Génération dynamique de présentations interactives en multimédia 3D, de données, pour les applications en ligne

Bonnel, Nicolas 04 December 2006 (has links) (PDF)
La recherche d'information textuelle fait partie des principales tâches liées au Web. Elle se fait majoritairement par des moteurs de recherche qui sont rapidement devenus incontournables. En effet, lorsque les utilisateurs ont une nouvelle tâche à accomplir sur le Web, ils démarrent - 88% du temps - par l'utilisation d'un moteur de recherche. Cependant, face à l'augmentation des informations disponibles sur le Web et à l'absence d'évolution significative du processus de recherche, la quantité de résultats obtenus pour une requête devient très importante. Il est alors difficile pour l'utilisateur d'interpréter efficacement tous ces résultats. Cette problématique est abordée en se plaçant du côté de la restitution des résultats de recherche à l'utilisateur via des interfaces utilisateur d'information (IUI). De nombreux travaux ont déjà été réalisés sur la visualisation des résultats de recherche au cours des dernières années, sans réelle influence sur les interfaces grand public. L'objectif de notre approche est de créer dynamiquement des présentations 3D interactives et basées sur des métaphores de visualisation adaptées à la fois à l'utilisateur, à la tâche à réaliser et aux données. Pour cela, nous avons développé un prototype - SmartWeb - proposant des interfaces hybrides (2D/3D) de visualisation de résultats de recherche. Il utilise le langage X-VRML qui permet d'exprimer efficacement les métaphores 3D de visualisation et de générer automatiquement des contenus 3D interactifs. Nous proposons alors une métaphore 3D cognitive permettant d'utiliser une représentation spatiale plus riche afin d'aider efficacement l'utilisateur dans sa tâche. Il s'agit d'une ville virtuelle dans laquelle les résultats sont organisés d'après le calcul d'une carte auto-organisatrice. Une étude utilisateur de cette interface est réalisée et une réflexion plus générale sur l'évaluation des IUI est proposée.

Impact des liens hypertextes sur la précision en recherche d'information.

Chibane, Idir 10 December 2008 (has links) (PDF)
Le Web est caractérisé par un volume d'information exponentiellement croissant ainsi que par l'hétérogénéité de ses ressources. Face au très grand nombre de réponses fournies par un moteur de recherche, il s'agit de fournir des réponses pertinentes parmi les premières réponses. Nous nous intéressons aux algorithmes de propagation de pertinence pour des corpus de documents hypertextes, et en particulier à l'analyse des liens afin d'exploiter l'information véhiculée par ses liens et par le voisinage des documents Web. Cependant, les différentes techniques proposées dépendent de paramètres statiques, fixés à priori selon le type de collection et l'organisation des pages Web. Dans cette thèse, nous proposons une nouvelle méthode de propagation de pertinence en utilisant des paramètres calculés dynamiquement, indépendamment de la collection utilisée. En effet, nous proposons de modéliser une fonction de correspondance d'un système de recherche d'information en prenant en compte à la fois le contenu d'un document et le voisinage de ce document. Ce voisinage est calculé dynamiquement en pondérant les liens hypertextes reliant les documents en fonction du nombre de termes distincts de la requête contenus dans ces documents. Pour traiter l'hétérogénéité des documents Web, nous modélisons les ressources Web à différents niveaux de granularité (site, page, bloc) afin de prendre en compte les différents thèmes contenus dans un même document. Nous proposons aussi une méthode de segmentation thématique des pages Web en utilisant des critères visuels et de représentation du contenu des pages afin d'extraire des blocs thématiques qui seront utilisés pour améliorer les performances de la recherche d'information. Nous avons expérimenté notre système sur deux collections de test WT10g et GOV. Nous concluons que notre modèle fournit de bons résultats par rapport aux algorithmes classiques reposant sur le contenu seul d'un document et ceux reposant sur l'analyse des liens (PageRank, HITS, propagation de pertinence).

Lost Tramps & Cherry Tigers

Bender, John Brett 23 July 2009 (has links)
These seven stories chronicle the author's apprenticeship as a fiction writer. Four are written in the first-person point of view, two are in a limited third-person, and one is written in third-person objective. The stories vary considerably with respect to character, tone, and setting; however, all may be said to explore the abjection and isolation of growing up in United States.

Att gilla eller inte gilla, det är frågan :  Hur användare förhåller sig till sidor på Facebook / To like or not to like, that is the question : How members relate to pages on Facebook

Norén Cermén, Sofie, Hallberg, Olle January 2010 (has links)
The development of the Internet has led to a new platform for Web pages, Web 2.0. An interactive environment where users generate content. Facebook, which is one of the most popular social media sites, has opened up new opportunities for companies to communicate directly with individuals. Facebook has encouraged this by offering the technology and the possibility by developing the feature pages.The purpose of this study was to examine how Swedish Facebook users relate to company's presence on Facebook through pages. The study also intended to find out how Swedish Facebook users think that companies should behave on their Facebook page. We have examined the awareness, the attitudes and the expectations that Facebook users have toward pages, and how the users utilize pages.The study was conducted by method triangulation: a survey based on 728 Swedish Facebook users, and four additional interviews. The study has public relations and Customer Relationship Management as theoretical framework.Our results show that the awareness of pages is high amongst the respondents. It also shows that they understand the meaning of pages, they explain the concept in the same way as Facebook does. The general attitude to pages is positive among the respondents, still there are many who does not like pages. It also appears that the reason that respondents like pages, or not like, are often related to how they want to present their own self-image. And also because they actually appreciate the company. It is important for the respondents that the companies keep users updated through their pages. It also emerged that many of the respondents use pages passively, meaning that they read about updates through their newsfeed instead of actively going into the pages. The study also shows that the respondents ask for two-way communication on pages, but they are not willing to take the initiative themselves. / Internets utveckling har lett fram till en ny plattform för webbsidor, Web 2.0. En interaktiv miljö där användarna genererar innehållet. Facebook, som är ett av de mest populära sociala medierna, har öppnat upp nya möjligheter för företag att kommunicera direkt med privatpersoner. Facebook i sin tur har uppmuntrat detta genom att erbjuda tekniken och möjligheten för detta i form av sidor. Syftet med denna uppsats har varit att undersöka hur svenska Facebook-användare förhåller sig till företags närvaro via sidor. Studien avsåg även att ta reda på hur svenska Facebook-användare tycker att företag ska bete sig på sin Facebook-sida. Vi har undersökt vilken medvetenhet, attityd och vilka förväntningar som Facebook-användare har på sidor, samt hur användarna nyttjar sidorna. Undersökningen har genomförts genom metodtriangulering: en enkätundersökning baserad på 728 svenska Facebook-användare samt fyra kompletterande intervjuer. Studien har public relations och Customer Relationship Management som teoretiska ramverk. Studiens resultat visar att medvetenheten om sidor är stor bland respondenterna. Den visar också att de har förstått meningen med sidor, de förklarar begreppet på samma sätt som Facebook menar att sidor ska användas. Den generella attityden till sidor är positiv bland respondenterna, ändå är det många som inte gillar någon sida. Det framgår också att anledningen till att respondenterna gillar sidor, eller inte gillar, ofta hänger ihop med hur de vill presentera sin egen självbild samt att de faktiskt tycker om företaget. Viktigt för respondenterna är att företagen också håller användarna uppdaterade genom sidorna. Det framkom även att många av respondenterna använder sidor passivt, det vill säga att de läser om uppdateringar via nyhetsflödet istället för att aktivt gå in på sidorna. Studien visar också att respondenterna efterfrågar tvåvägskommunikation på sidorna, men att de inte är beredda att ta det initiativet själva.

Utilising human capital as an organisational asset / C.E. Human

Human, Christine Elsje January 2005 (has links)
The objectives of this study are to determine the awareness level of knowledge sharing amongst the employees of Sasol, to determine how Sasol utilises human capital in the company and to identify and analyse the methods of knowledge sharing and knowledge transfer. The literature review distinguishes between explicit and tacit knowledge. Explicit knowledge leads a company to codify while tacit knowledge leads to connecting people. The literature study also covers the utilisation of human capital and identifies methods of knowledge sharing and -transfer, namely legacy pages, expert location systems, buddy systems, post-retirement agreements, identification of successors, After Action Reviews, interviews, observation, protocol analysis, teach backs, story writing and storytelling, and process mapping. The literature study forms the foundation for the formulation and designing of a questionnaire. The questionnaire was distributed amongst the employees of two of Sasol's divisions in order to obtain data about the utilisation of human capital in Sasol and to identify and analyse the current and preferred methods to capture and share tacit knowledge and skills. The data obtained from the questionnaires was processed, analysed and interpreted. Conclusions were drawn, linking the literature review and the results obtained from the empirical study. Based on these conclusions, recommendations were made. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2006.

Building a multi-tier enterprise system utilizing visual Basic, MTS, ASP, and MS SQL

Poti Allison, Tamara S. January 2001 (has links)
Multi-tier enterprise systems consist of more than two distributed tiers. The design of multi-tier systems is considerably more involved than two tier systems. Not all systems should be designed as multi-tier, but if the decision to build a multi-tier system is made, there are benefits to this type of system design. CSCources is a system that tracks computer science course information. The requirements of this system indicate that it should be a multi-tier system. This system has three tiers, client, business and data. Microsoft tools are used such as Visual Basic (VB) that was used to build the client tier that physically resides on the client machine. VB is also used to create the business tier. This tier consists of the business layer and the data layer. The business layer contains most of the business logic for the system. The data layer communicates with the data tier. Microsoft SQL Server (MS SQL) is used for the data store. The database containsseveral tables and stored procedures. The stored procedures are used to add, edit, update and delete records in the database. Microsoft Transaction Server (MTS) is used to control modifications to the database. The transaction and security features available in the MTS environment are used. The business tier and data tier may or may not reside on the same physical computer or server. Active Server Pages (ASP) was built that accesses the business tier to retrieve the needed information for display on a web page. The cost of designing a distributed system, building a distributed system, upgrades to the system and error handling are examined.Ball State UniversityMuncie, IN 47306 / Department of Computer Science
