Impact of the Four Quality "Training, Service, Information System and Information" on the Use of Information System in an Information-Intensive Sector

Today, information is crucial and the flow of information is becoming more and more numerous, so their management is delicate, hence the need to use an information system that supports all production systems, and the majority of competitive advantages is achieved through the intelligent use of these information systems.It is in this context of disrupted information that the use of information systems is necessary in organizations, as they have greatly influenced the ways of work and management. For this purpose, they allow easy access to relevant information in quantity and in real time, the rapidity of analyzing this information and the possibilities for dissemination and exchange between the partners, without forgetting the possibilities for storage and archiving in a more secure way than human intervention could.The study examines the impact of quality of training, service quality, information system quality and information quality on the use of an information system. A quantitative study is conducted to test these effects, the findings of this research are mainly comprised by three facts: (1) the use of information systems is obligatory in the context of intensive information. (2) Voluntary or mandatory use status must be specified in the analysis, (3) there is no specific antecedent to the act of use of IS in the retail secto

L’impact Des Systèmes D’information Sur La Performance Des Chaines Logistiques: Une Revue De Littérature

In the context of global competition which is characterized by a variety of products, short life cycles, and a competitive pressure between the supply chains, the cooperation and collaboration between companies has become very crucial. These collaborative relations improve the coordination of activities within the supply chains and have resulted to a higher performance through the use of information systems. These information systems have enabled it to face the rise in the complexity of the logistics sector which was born out of the information. To better position our contribution, we made a review of the literature and defined the variables and the hypotheses of this research work

Les systèmes d'information comme leviers de la performance logistique

Au cours des dernières années, la relation entre la performance logistique et l‘utilisation des systèmes d‘information a été étudiée conceptuellement et empiriquement dans la littérature. Cette relation trouve toute sa pertinence avec l‘avènement des nouvelles technologies de l‘information et de la communication.  A travers cet article, nous visons à explorer les liens entre l’usage des systèmes d’information et la performance logistique. Dans un premier lieu nous allons présenter la place du système d’information dans l’organisation, le premier axe met en lumière le concept du système d’information et avance un ensemble de définitions. Le second axe met l’accent sur les systèmes d’information utilisés dans une chaine logistique avec la notion du partage d’informations. Enfin, le dernier axe avance une synthèse de travaux montrant la relation entre l’usage des systèmes d’information et la performance logistique

Comparison of climate change impacts on the recharge of two karst systems computing different modelling approaches

International audienceKarst systems constitute aquifers in which infiltration and groundwater flows are generally complex processes and are characterized by limited knowledge in terms of geometry and structure. Nonetheless, they often represent interesting groundwater resources, some of them being subjected to intensive exploitation and others non exploited due to their poor understanding. In the future, it is likely that climate change impact on water resources will increase the interest for such a kind of aquifers due to their strong infiltration and storage capacity, in a broad context of higher water scarcity.The Lez and the Lison karst systems in Southern and Eastern France, respectively, provide 2 examples of such systems of several km² under two contrasted climate conditions, the first one being heavily exploited. This study presents a comparative climate change assessment onboth karst systems. Nine climate scenarios corresponding to the Fourth assessment report of the IPCC (SRES A1B scenario), downscaled using weather-type methods by the CERFACS, have been applied to various recharge modelling approaches, as standard analytical solutions of recharge estimation and soil-water balance models. Results are compared and discussed in order to assess the influence on climate change impacts of i) the climate conditions(geographic location), ii) the groundwater exploitation and iii) the modelling approach
