Factories have to adapt permanently to changing situations in order to stay competitive. Premise to achieve this objective is up-to-date information on all levels of a factory and during the product life cycle, so that men and machine can optimize their activities according to their tasks. One approach to implement this economically is the massive application of sensors and information and communication technologies (ICT) leading to a Smart Factory. This process and related applications are summarized under the term of the forth industrial revolution (Industrie 4.0). It demands a flexible and easy-to-use integration of assets on the shop floor with ICT systems. The contribution of this paper is the MIALinx system that enables all these steps. The steps range from the integration to the sensing and analyzing of the sensor data to the execution of required actions. Furthermore, MIALinx provides an abstract rule based approach for users to model the behavior of the system. The presented system is based on concepts and technologies of the Internet of Things and service-oriented middleware. The main users targeted with our system are small and medium-sized enterprises that do not have the expertise or the investment possibilities to invest in completely new Industrie 4.0 systems but rather use their existing production assets and enrich them to achieve Industrie 4.0 capability.
