Summary:The invention relates to a system and method for generating a radiotherapy treatment plan on the basis of treatment goals comprising optimization objectives and/or constraints. A planning unit (7) generates a first treatment plan including treatment parameters for fulfilling first treatment goals in a first optimization cycle, and a decision unit (8) receives second treatment goals and compares the first and second treatment goals to 5 determine a modification of the treatment goals, assigns to the modification a category from a plurality of predetermined categories, wherein to each category a strategy from a plurality of predetermined strategies for treatment plan generation is allocated, and instructs the planning unit (7) to generate the second treatment plan in accordance with a strategy allocated to the determined category of modifications in a second optimization cycle.
