Economists' policy advice is based on models of responses by a variety of economic entities to policy adoptions. There is compelling evidence that these entities do not optimize in at all the fashion that mainstream economics assumes. Rather, they limit decision-making to solving problems of...

Problem-based learning (PBL) is an instructional model that assumes the centrality of problems to learning. Research on PBL has focused on student learning, student roles, tutor roles, problem design, and technology use (Hung, Jonassen, & Liu, 2008), but little attention in the PBL literature...

We consider the movement minimization problem in a conveyer flow shop processing controlled by one worker that has to serve all machines. Each machine can only execute tasks if the worker is present. A few jobs can be queued in a buffer in front of each machine. The objective is to minimize the...

We consider the combinatorial stack-up problem motivated by stacking up bins from a conveyor onto pallets. The stack-up problem is to decide whether a given list q of labeled objects can be processed by removing step by step one of the first s objects of q so that the following holds. After each...
