  A common issue for companies is that the volume of product orders may at
times exceed the production capacity. We formally introduce two novel problems
dealing with the question which orders to discard or postpone in order to meet
certain (timeliness) goals, and try to approach them by means of model-based
diagnosis. In thorough analyses, we identify many similarities of the
introduced problems to diagnosis problems, but also reveal crucial
idiosyncracies and outline ways to handle or leverage them. Finally, a
proof-of-concept evaluation on industrial-scale problem instances from a
well-known scheduling benchmark suite demonstrates that one of the two
formalized problems can be well attacked by out-of-the-box model-based
diagnosis tools.
