Resilience of Productions Systems by Adapting Temporal or Spatial Organization

Turbulent changes of the production program regarding the variation of the number and type of products challenges the suitability of the operating point of the production system. This can result in a lack of efficiency and productivity of a formerly mature configuration of a production system. In this case, the logistic positioning in terms of a proper operating point becomes obsolete. Therefore, a periodic monitoring of the system configuration is necessary to ensure a resilient production. This refers to an adaption of both the temporal and spatial structure of the production system. To cope with those challenges, this paper introduces an approach which evaluates strategies in terms of adjusting the system configuration. In this context, measures regarding capacity alignment and adaption are taken into account. On the one hand, this refers to control strategies influencing the temporal organization and thus the system's behavior. On the other hand, also a variation of the spatial organization in terms of the layout of the production system (system structure) is considered in order to detect the ideal operating point of the system. For this purpose, the characteristic curves of relevant parameters are scaled to the point that a comparison of different system configurations is enabled. After the explanation of the detailed approach, the application is shown using several use cases. For different production systems effects of a changed production program on the system configuration and its resilience is explained and adequate measures for adapting the temporal or spatial structure are evaluated. Finally, the suitability of taken strategies is verified in terms of the identification of new ideal operating points.
