Abstract: A method for providing a planning framework for use in managing a project to be planned in a supply chain, comprising providing a first software layer for storing and manipulating planning data relative to the planning project; providing a second software layer for communicating with the first software layer, the second layer arranged for pre processing, preparing and post processing a predetermined planning method. By such a multilayered framework, the invention is able to execute a planning algorithms to solve multi-level planning problems, wherein generic modules can be executed as fast modules in an environment that is highly optimized in terms of load on time and system resources and specifically adapted modules are embodying a particular planning strategy that can operate on a different level that is highly flexible.
