A method and an assistance system for supporting a multistage decision process for producing a work plan for a reduction process is provided. The decision process proceeds from a formulation of tasks, which uniquely characterizes the initial situation on which the decision process is based. In particular, the decision process proceeds from a feature-based CAD model of the workpiece to be produced. The decision process also includes individual decisions, which are built on one another hierarchically and are combined with one another in the form of a decision tree. In order to support the production of a work plan, use is made of an assistance system which is coupled to a database in which the individual decisions taken in the past are stored as cases, those cases which correspond to individual decisions building on one another hierarchically being combined with one another in a relational fashion. The assistance system also makes available for each individual decision a user-defined similarity measure with the aid of which it is evaluated how well a case stored in the database in relation to this individual decision is suitable as a solution for this individual decision. Specific rules are used to adapt this case to the current individual decision.
