    Entwicklung einer kontextbasierten Systemarchitektur zur Verbesserung des kooperativen Einsatzes mobiler Arbeitsmaschinen
    (2018) Steckel, Thilo; Griepentrog, Hans
    In contrast to industrial production processes, agricultural processes are characterized by high uncertainty in terms of planning and execution. Main reasons for this are system-induced high environmental exposure, high complexity of the technical systems, a low division of labor and the lack of applicable systems for decision-making and support.Low process transparency and suboptimal decisions result from that. This observation becomes measurable by comparison of installed performance, determined under ideal conditions, and realized performance, determined from literature and telematics data, which are at a level of approximately 40 to 50%. In the present work the causes for this gap are analyzed and a method for their reduction is developed. Key to improving the situation is the systematic use of context-oriented approaches. The context dimensions time, space and system are described and related to each other. In this way, decision-relevant process conditions in agricultural work processes can be described in a structured manner. On the basis of these contexts, components are derived which, in a subsequent system architecture, enable the automated identification, description and evaluation of process contexts. On this basis concrete measures for the improvement of processes can be derived within the scope of the given possibilities (eg machine performance, drivability). The principle of system architecture is exemplified by the example of the harvesting of silo maize (chipping, transport, storage). The process is modeled from a contextual viewpoint and implemented as agent-based simulation, taking into account the above defined components. In order to carry out the simulation, performance (eg. throughput) and cost-relevant (eg. fuel consumption) parameters are recorded on real machines and production functions are developed. The simulation provides the costs and time requirements for a given process configuration (performance of the forage harvester, number, speed and capacity of the transport vehicles as well as number and mass compacting vehicles). In a parameter configuration based on this simulation a solution space is created which can be used to derive advantageous behaviors. Performance-determining parameters in the determined limits and defines step size are used for that. In addition to the simulation, a mathematical method for the generation of logistic characteristics is developed. Simulation and characteristic fields provide the possibility discreet or continuous approaches of the processes. For verification, results are compared with an empirical survey by questioning farmers and contractors. The described approach allows qualified decisions to improve cooperation in processes and thus contribute to the reduction of the abovementioned performance gap. However, the limits of the improvements result from the locally prevailing environmental conditions and must be defined by the user. Further steps for the control and optimization of processes can be developed on the described approach.

    From passion to performance : entrepreneurial passion in the creative industries
    (2022) Schulte-Holthaus, Stefan; Kuckertz, Andreas
    Entrepreneurship drives progress, innovation, growth, and prosperity. Passion, in turn, motivates and energizes people to pursue meaningful activities on a sustained basis. In following their passion and in interacting with their proximal environments, people build up competencies, knowledge, experience, and social relations, which may result in peak performance. When passion develops and relates to the creation, discovery and exploitation of entrepreneurial opportunities, entrepreneurial passion emerges. The current state of research shows that entrepreneurial passion is a source of motivation, inspiration, creativity, and perseverance. In the cultural and creative industries, entrepreneurship often begins from a passion for an artistic or creative work that is pursued as a hobby or leisure activity, which professionalizes over time. Thereby, passion for a creative or artistic activity can also create tensions between ideational and economic-organizational imperatives in entrepreneurial contexts. However, how, and why an artistic or creative passion develops into an entrepreneurial one and how it affects entrepreneurial success is unchartered territory. Hence, the aim of this dissertation is to investigate and explain the development of passion and its effect on entrepreneurial performance of creative people whose venturing ambitions are primarily driven by a non-entrepreneurial passion. The first study identifies the current state of literature on entrepreneurship in the cultural and creative industries. The review elaborates the phenomenon of a non-entrepreneurial passion as central feature of creative industries entrepreneurship and outlines its potential for future research. The second study presents a review of the state of research on passion in the entrepreneurial context and develops a theory-based approach that explains how passion emerges, and how it can extend to entrepreneurship and lead to entrepreneurial performance. Based on 11 semi-structured interviews with successful entrepreneurs whose life paths are characterized by passion for music, the third study follows this assumption and generates mental maps using the Conceptual Causal Mapping method. The results explain the development of real-life passion over time, its current constitution and embeddedness within the personal, social, and entrepreneurial life context and the relation of passion to performance. Based on the person-environment fit theory, the final study develops a model that substantiates the positive effects of life context fit on entrepreneurial passion and performance. Life context fit is operationalized using personal project analysis and the hypotheses were tested on a sample of 406 creative entrepreneurs using partial least squares structural equation modeling. The results demonstrate the effect of life context fit on entrepreneurial passion and its successive translation into performance in four subsegments that can be classified as artepreneurs, culturepreneurs, creative entrepreneurs, and lifestyle entrepreneurs. However, contrary to expectations, the analyses also indicate that neither the life context fit, nor the domains of entrepreneurial passion have uniform positive outcomes. Rather, these relations occur with compounded positive and negative effects. These results are surprising as the extant literature has found nearly consistent positive outcomes of passion on performance. Post-hoc analyses reveal the varying constitutions of life contexts and the existence of previously unmeasurable domains of entrepreneurial passion for products, for people, and for a social cause among creative practitioners and help explaining the positive and negative combination effects in the segments. Overall, this dissertation contributes to the cultural and creative industries literature, the state of research on passion in entrepreneurship and psychology, and the literature whose epistemological interest aim at capturing and explaining entrepreneurial contexts and environments. Findings reveal (a) the central importance, development, and impact of passion among creative and cultural entrepreneurs, (b) the influence of life context on passion and performance, and (c) the interplay of combined positive and adverse effects of the domains of entrepreneurial passion and their impact on entrepreneurial performance.
