"In the research domain Complex Problem Solving (CPS) in psychology, computer-supported tests\r\nare used to analyze complex human decision making and problem solving. The approach is to use\r\ncomputer-based microworlds and to evaluate the performance of participants in such test-scenarios\r\nand correlate it to certain characteristics. However, these test-scenarios have usually been defined\r\non a trial-and-error basis, until certain characteristics became apparent. The more complex models\r\nbecome, the more likely it is that unforeseen and unwanted characteristics emerge in studies.\r\nIn this thesis,we use mathematical optimization methods as an analysis and training tool for Complex\r\nProblem Solving, but also show how optimization should be used in the design stage of new\r\ncomplex problem scenarios in the future. We present the IWR Tailorshop, a novel test scenario with\r\nfunctional relations and model parameters that have been formulated based on optimization results.\r\nThe IWR Tailorshop is the first CPS test-scenario designed for the application of optimization and is\r\nbased on the economic framing of another famous microworld, the Tailorshop.\r\nWe describe an optimization-based analysis approach and extend it to optimization-based feedback\r\nwith different approaches for both feedback computation and feedback presentation. Additionally,\r\nwe investigate differentiable reformulations for an unavoidable minimum expression and show\r\nthe according numerical results. To address the difficulties of computing globally optimal solutions\r\nfor this test-scenario, which yields non-convex mixed-integer optimization problems, we present a\r\ndecomposition approach for the IWR Tailorshop. The new test-scenario has been implemented in a\r\nweb-based interface together with an analysis software for collected data, which both are available\r\nas open-source software and allow for an easy adaption to other test-scenarios.\r\nIn this work, we also apply our methodology in a web-based feedback study using the IWR Tailorshop\r\nin which participants are trained to control the microworld by optimization-based feedback.\r\nIn this study with 148 participants, we show that such a feedback can significantly improve participants’\r\nperformance in a complex microworld with a possibly huge difference to a control group.\r\nHowever, the performance improvement depends on the representation of the feedback. We give a\r\ndetailed analysis of the study and report on new insights about human decision making which only\r\nhave been possible through the IWR Tailorshop and our optimization-based analysis and training\r\napproach."^^ .
