Based on a real-world application in the semiconductor industry, this article models and discusses a hybrid flow shop problem with time dependencies and priority constraints. The analyzed problem considers a production where a large number of heterogeneous jobs are processed by a number of machines. The route that each job has to follow depends upon its type, and, in addition, some machines require that a number of jobs are combined in batches before starting their processing. The hybrid flow model is also subject to a global priority rule and a “same setup” rule. The primary goal of this study was to find a solution set (permutation of jobs) that minimizes the production makespan. While simulation models are frequently employed to model these time-dependent flow shop systems, an optimization component is needed in order to generate high-quality solution sets. In this study, a novel algorithm is proposed to deal with the complexity of the underlying system. Our algorithm combines biased-randomization techniques with a discrete-event heuristic, which allows us to model dependencies caused by batching and different paths of jobs efficiently in a near-natural way. As shown in a series of numerical experiments, the proposed simulation-optimization algorithm can find solutions that significantly outperform those provided by employing state-of-the-art simulation software.
Vitalpolitik
(2022)
Abstract: This chapter reconstructs the notion of ‘vital policy’ (Vitalpolitik), an approach to the social question whose first and strongest proponent amongst the Ordoliberals was Alexander Rüstow. It is opposed to traditional social policy as a top-down provision of material benefits (welfare). Instead, it aims at enabling those ‘conditions of life’ (Lebenslagen) that provide the prerequisites for human beings and their community to flourish. This humanistic approach attempts to complement the competitive processes in a market society and to provide access and equal opportunity to these processes, focusing on the notion of fair starting conditions for individuals. In its general thrust, Vitalpolitik is well compatible with more recent research programmes, especially the capability approach of Amartya Sen and Martha Nussbaum.
Stefan Kolev zeichnet in seinem Beitrag die Geschichte und Bedeutung des schillernden Begriffs »Neoliberalismus« nach, welcher vielfach als Grund allen Übels gegen liberales Denken und Politik in Stellung gebracht wird. Kolev plädiert dafür, dass der Liberalismus sich immer wieder erneuern muss, also stetig neue Neoliberalismen benötigt.
