Proposition d'un modele integre temps/cout/qualite sous incertitude en planification de projet.

摘要

With the development of the technology and economics, the project management gradually becomes the focus of the management theory and practice. To stay competitive, companies are increasingly implementing initiatives to improve their project delivery by continually reducing cycle times, minimizing costs, and controlling quality. These dimensions (quality, time, and cost) are also referred to as the Project Management Triangle where each side represents a constraint. One side of the triangle cannot be changed without impacting the others. The time constraint refers to the amount of time available to complete a project. The cost constraint refers to the budgeted amount available for the project. The scope constraint refers to what must be done to produce the project's end result. These three constraints are often competing constraints: increased scope typically means increased time and increased cost, a tight time constraint could mean increased costs and reduced scope, and a tight budget could mean increased time and reduced scope. The discipline of project management is about providing the tools and techniques that enable the project team (not just the project manager) to organize their work to meet these constraints. Project Management tries to gain control over these three variables taking account the uncertainty inherent to every project situation. It requires skilled people, standardized processes, and technology---unified and driven by effective project management. This thesis tackle this difficult problem and proposes a general framework, based on the WBS that can be implemented to combine earned value management, earned quality management and risk management in order to 'maximise' the likelihood of achieving project objectives (time/cost/quality).; Key words. Time, cost, quality, risk, project management.
