Nowadays, major challenges of the manufacturing industry are the shortening of product life-cycles and the trend towards personalized productions. This trend is a tremendous turnaround in the industry, since the last decades were coined by mass productions at low costs. Although the demands of current products increased, the price level should stay the same. Therefore, the improvement of flexibility of automation systems is a current issue, in order to enable the implementation of product specific changes with little effort. This thesis targets this issue by developing and implementing a concept for a flexible process control, based on a domain specific tool, which enables the creation of production recipes by process engineers, without reconfiguring the plant. In order to control the equipment, services in terms of a Service-Oriented Architecture are provided. Based on the recipe, a recipe processing algorithm calls the corresponding services from the equipment. For demonstrating purposes, this concept is evaluated on two linked laboratory tank system plants, which enable process actions for pumping, heating, and mixing. Furthermore, for improving the concept of a flexible process control even more, a dynamic route finding algorithm is integrated, which finds the shortest path for pumping processes based on a model of the plant.
