Modélisation agile pour un système de fabrication complexe et dynamique

Abstract : In a full automation context with a strong Information Technology (IT) component, organizational transformations should always be accompanied by an evolution of the different information systems. In that sense, operational users of the information systems must recognize the use of information systems in terms of their functionality, and their ability to rapidly and continuously answer the requirements of the evolution of the organization.Having Information Systems (IS) which reflect businesses is not a luxury for companies. The shortfall for the company in the absence of alignment is the impact on the organization performance: The non-adequacy of the IS limits the daily tasks and degrades the potential benefits of full automation. Thus, the production system is conditioned by the IS. Beyond its functional necessity, alignment is also justified by the cost of its implementation compared to a non-alignment.This thesis aims at ensuring systematic and continuous Business / IT alignment in a complex and dynamic environment.Our study was led by the specificity of the case study and the literature review. We propose a methodology based on a "Reference Model" to minimize the Business / IT alignment gap. From a functional standpoint, the methodology relies on capturing user requirements in a Reference Model and finding acceptable compromises for the IT development, to reach the alignment incrementally. The methodology is applied on a “processability” case study in semiconductor manufacturing.
