Against the background of Cyber-Physical Production Systems (CPPS), working systems – focused on hybrid assembly systems – will be significantly changed.

Figure 1: Selected changeing aspects of Working System Design in CPPS (Dombrowski, 2014)

The conduct of such business within a highly dynamic, ever-changing work environment goes hand in hand with increasing requirements to the human being and his working capacity. New forms of situation-driven collaborations between "Humans" and the technical "System" will be created. To obtain and to increase productivity of working systems, the consideration of the human performance within CPPS is particularly relevant. Under this consideration CPPS offer many possibilities to realize batch size one under condition of mass production as well as many possibilities for a human-oriented working design and provide opportunities for an age-appropriate work design, whereby the consequences of customers' individuality as well as the consequences of demographic change can be managed.

Objective and Organization:

Currently unexplained is the question how a technical and ergonomic integration of the worker in a dynamic assembly working context can be managed. A central question in this context is how work instructions and technical support can be created in a dynamic interaction between "Human", "Organization" and "Technology" in order to guarantee productivity and ergonomic continuously.

A possible approach is to enable assembly working systems in a way in which fuzzy information of the environment and organization as well as the flexibility and transformation potential of the assembly technology such as the human performance can be compared with the constraints and characteristics of the assembly as well as with the production and assembly planning, controlling and configuration respectively.

Against this background, the aim of the dissertation is to develop a planning and control method as well as a technical implementation concept that ensure through appropriate worker support and situation-related technical worker assistance a productive and ergonomic working system configuration.

In order to archive the objective of the dissertation, the technical interaction and functional mechanisms as well as the principles between "Human", "Technology" and "Organization" in the (hybrid) assembly system have to be identified and analysed. After that suitable KPIs (Key-Performance Indicators) and their qualitative and quantitative effects and influences on ergonomics, productivity and quality are to investigate and a set of rules is to be defined.

By a correlation and mathematical model as well as by automated regulation and intervention functions, a specific control method as well as a technical implementation concept is to develop. Finally, this method is to be evaluated within a semi-industrial "use case".
