資料庫行銷-顧客資料庫的建立及其應用之研究 / Database Marketing - Establishment and Application of Customer Database劉穎壽, Andy Liu, Ying Show Unknown Date (has links)
近年來由於消費者行為以及行銷環境的改變,行銷人員開始試圖從傳統的行銷手法中尋求突破,以獲取企業在行銷上的競爭優勢。藉由資訊及電子通訊科技之助,資料庫行銷可以創造新的行銷機會,並提高行銷績效。在國內,則由外商公司率先引進資料庫行銷技術,而許多企業也逐漸意識到顧客資料的重要性,因此如何建立一套有效的顧客資料庫並將其應用在行銷方面,便成為有心從事資料庫行銷者普遍關切的問題。
本研究屬於探索性的研究,藉由對國內外相關文獻的探討,發掘企業在從事資料庫行銷時必須掌握的關鍵因素,並進一步對國內企業進行實證研究,以了解企業之資訊系統、組織特質、行銷組合與資料庫行銷之間的互動關係。
經由文獻探討以及對實際個案公司經驗的研究分析,本研究發現企業本身資訊化及系統整合的程度會影響資料庫行銷的成效;企業各分公司之間經驗的轉移可以增進行銷人員的資料庫行銷技術,並提高成功的機率。高階主管對資料庫計劃的支持與承諾及行銷組織結構的配合均是成功的關鍵因素。此外,企業本身之產品或服務的特性以及行銷通路均須與資料庫行銷相配合方能發揮其最大的成效,而資料庫行銷的應用也有助於公司產品的發展及通路的開發。
資料庫行銷在國內的發展尚未完全成熟,但是未來將會更為普及,一些較為高層次的應用如資料庫分析的統計模式技術以及資料庫行銷對整合性行銷溝通之影響均為未來相當值得研究之議題。

Analyse de sûreté de procédés multi-modes par des méthodes à base d'intervallesShahriari, Kyarash 03 May 2007 (has links) (PDF)
Lorsqu'un système physique est en fonctionnement, un des objectifs d'une analyse de sûreté est d'être sûr que les variables caractérisant l'état du système suivent une certaine trajectoire ou restent dans une zone donnée compte tenu de toutes les perturbations et les incertitudes sur les paramètres et les mesures du système. Une solution originale pour ce problème est proposée dans ce document à l'aide d'une approche ensembliste qui consiste à calculer l'ensemble des trajectoires possibles générées en présence des perturbations dues à l'environnement du système et à la méconnaissance des modèles du système se traduisant par des incertitudes sur la valeur de certains de ses paramètres. Dans le cas de notre problème, les incertitudes peuvent porter sur les valeurs des paramètres, l'état initial ou les mesures du système. Pour garantir le résultat de l'analyse de sûreté, toutes les trajectoires doivent être envisagées, pour toutes les perturbations et les incertitudes considérées. Pour représenter le comportement d'un système complexe (un système multi mode ou un système non-linéaire), au lieu d'utiliser un modèle avec une structure complexe, une approche standard est de diviser le régime opératoire du système en zones locales est de représenter chaque zone par un modèle linéaire avec une structure simple.On essaie dans ce travail de thèse d'apporter une solution au problème d'identification de systèmes incertains dans un premier temps par un modèle mono-mode et ensuite par un modèle multi-mode pour un objectif d'analyse de sûreté de système. Ce document est constitué de cinq chapitres. Dans le premier chapitre, la problématique du travail est détaillée. Dans le deuxième chapitre, un état de l'arc sur la problématique étudiée est donné. On traite ensuite du problème d'identification et de simulation d'un modèle ensembliste (intervalle) dans le chapitre trois. Pour améliorer la qualité de lé modélisation et augmenter la précision de la prédiction, une approche méthodologique est proposée dans le chapitre quatre pour identifier et pour simuler ce modèle intervalle. Dans le dernier chapitre, une conclusion est apportée sur l'ensemble de ce travail de thèse.

Previous issue date: 2004-04-15 / La recherche de la formation des citoyens critiques et participatifs, dans le travail p?dagogique avec les jeunes et les adultes, a besoin d un entra?nement p?dagogique qui va au del? de l attitude traditionnelle d'apprendre avec des m?thodes m?caniques et arbitraires qui, en insistant excessivement sur l image du professeur, donnent priorit? ? l'enseignement, au d?triment de l apprentissage.

Dans ce travail, le jeune ?tudiant et l ?tudiant adulte est pris comme individu concret, prenant en consid?ration les aspects cognitifs et les aspects d attitude de son apprentissage, ce qui est favoris? par la nature des lettres du tarot et par la compr?hension adopt?e, des math?matiques comme syst?me symbolique / A busca da forma??o de cidad?os cr?ticos e participativos, no trabalho educativo com jovens e adultos, enseja uma pr?tica docente que v? al?m da postura tradicional de ensinar com m?todos mec?nicos e arbitr?rios, que, ao focarem excessivamente a figura do professor, priorizam o ensino, em detrimento da aprendizagem.

Pretende-se, com isso, mostrar tal instrumento como facilitador da aprendizagem de conte?dos da Matem?tica como sistemas de numera??o, n?meros inteiros e geometria, tomando a Matem?tica numa perspectiva hist?rico-cultural e dando um tratamento hol?stico ao complexo ato de aprender. Nesse trabalho, o aluno jovem e adulto ? tomado como indiv?duo concreto, levando-se em considera??o os aspectos cognitivos e atitudinais de seu aprender, o que ? favorecido pela natureza das cartas do tar? e pela compreens?o adotada, de matem?tica como sistema simb?lico

Mikroelektronick© ÄasovÄ-prostorov© autentizaÄn techniky / Microelectronics Time-Space Authentication TechniquesJaro, David January 2015 (has links)
This dissertation work focusses on using information about the location of the user during the authentication process on computer networks. With the growth of mobile computer devices over the last two decades the physical location of users is becoming one of the main issues for access management. This work researches existing solutions which are divided in to two groups related to the source of location information (SATNAV systems for example GPS and based on communication with active infrastructure such as GSM, Wi-Fi). This work shows the methodology for evaluating authentication data which use the principle of fuzzy logic. In comparison with binary logic it is possible to evaluate authentication data accurately. As a result of the authentication process the information is of a higher value, which can be taken into account when setting the levels of user privileges. An important aspect of working with location information is that the user is located in the same place and from where they are asking for access to the system. Solving this question could be linking user biometrics for example finger prints. This principle is used in two types of microelectronic authentication terminals which were developed in conjunction with this work. The first type of terminal uses a SATNAV receiver and an ISM wireless communication module as a source of location information. On the first type of authentication terminal newly developed authentication techniques were tested. The users biometrics are checked by finger print sensor with embedded processing. In the second type authentication terminal a Wi-Fi and GSM module were added for location purposes. In the conclusion of this dissertation the testing methodology of the data authorization and evaluation process of the second type of microelectronic authentication terminal is shown. This confirms the practicality of the suggested methodology and the time-space information in the authentication process.
