A Graph-based and Declarative Approach to a Secure Resource Management in Smart Factories

Abstract. The article presents an applied research using the Design Science Research Methodology for securely managing resources of smart factories via a graph-based approach combined with a declarative query language. This query language can be used to find appropriate production facilities that are able to fulfill specific manufacturing tasks. This approach is aimed to solve the problem with the management effort for production facilities using enumeration for naming these facilities for the manufacturing tasks. Thus, the security is ensured by identifying the “current” valid identities (resources). Additionally, the usage of deputy relationships leads to alternative production facilities if resources have a breakdown or have to be serviced which has an effect on the availability.
