Design tasks like innerplant planning of locations, cannot be solved by one single problem solving method like, for instance, Top-Down-Refinement. In reality, the planners very often jumps from one level of abstraction to another, and from one subtarget to another. The special blackboard architecture explained in this article is suited to simulate this human problem solving behaviour. Another aspect of human problem solving in this field is the ability to reject former actions and the implications. This sofware architecture will be able to support Dependency-Directed-Backtracking, as with TMS. Together with the general advantages of blackboard systems concerning complex problems as innerplant planning, it is allowed to say that this particular architecture might be a practicable concept to handle design tasks.
