Devices in industrial automation systems are becoming more and more intelligent. Consequently, functions such as server services are migrating into the device level. To solve the resulting connection mesh, this paper entails the concept of aggregation of servers connected to devices in an industrial automation scenario. The first section discusses the basic requirements for aggregation and proposes an architecture for server aggregation as a solution. The following section describes the building blocks of the architecture. Finally, the paper presents a prototype based on this architecture model as a proof of concept implementation of the concept introduced in this paper. The last section discusses the results of the prototyping phase including the possible improvements of the same.
The running costs of production sites are a decisive factor in the overheads of automotive production. Because of this, it is important for many operators to decrease those costs in a sustainable way. Therefore, they try to reduce both the energy consumption costs of production systems, as well as their maintenance costs. However, most parts of the running costs are already determined during the very early phases of the product creation process. The approach in this paper shows how the decision for a specific manufacturing technology influences the factory costs. It is necessary to determine the life-cycle costs with regard to the manufacturing technology. Therefore, deep knowledge about the process itself and the support processes is required. This paper shows how cost relevant parameters can be identified and introduces a method to determine the prospective costs for maintenance and energy consumption in advance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
