Task-Specific Decision Support Systems in Multi-Level Production Systems based on the digital shadow
(2019)
Due to the increasing spread of Information and Communication Technologies (ICT) suitable for shop floors, the production environment can more easily be digitally connected to the various decision making levels of a production system. This connectivity as well as an increasing availability of high-resolution feedback data, can be used for decision support for all levels of the company and supply chain. To enable data driven decision support, different data sources were structured and linked. The data was combined in task-specific digital shadows, selecting clustering and aggregation rules to gain information. Visual interfaces for task-specific decision support systems (DSS) were developed and evaluated positively by domain experts. The complexity of decision making on different levels was successfully reduced as an effect of the processed amounts of data. These interfaces support decision making, but can additionally be improved if DSS are extended with smart agents as proposed in the Internet of Production.
Current supply chain structures in the spare parts logistics are changing profoundly due to the influence of digitalization and additive manufacturing (AM). In particular the Logistics Service Provider (LSP) is influenced by the change, as the physical transport of goods could become redundant due to the digital transmission of production data. This leads to a reduction of the LSP’s share in the value chain. Conceptualizing a new role for the LSP for additively manufactured spare parts is necessary. Therefore, five different scenarios are identified in which the LSP serves as a transport carrier, digital distributor, an AM decision maker, a selector of the manufacturer and as an AM service provider.
