A modelling environment based on data warehousing to manage and to optimize the running of international company

We propose a modelling environment to manage the sales abroad considering production, sales and foreign exchange risks in order to help the company to be more competitive at international levels and to maximize its profits. This modelling environment is based on data warehousing and knowledge discovery in databases coupled to performance evaluation by discrete event simulation. It allows to understand and to evaluate the business in taking into account its environment (for example the economic context). It will be used in order to help companies to develop their business, and especially when they want to sell abroad. We present on the one hand, the architecture of modelling environment and on the other hand, the logical models of the proposed data warehouse. An example of use of the modelling environment is proposed relating to the management of the foreign exchange risks.
