Flexibility and Interoperability is becoming – in addition to price and quality strategies – an increasingly important competitive factor.

Networked machines, software, employees, suppliers, customers are a reality. Unfortunately, the design and engineering of software for decentralised and distributed socio-technical production systems is reaching quite often its limits. PROFACTOR researches and develops infrastructure and algorithms for flexible production systems, assist people in making decisions which can’t be reached with methods based on experience alone. Plant operators can – for example – by means of model-based methods test system configurations that are most promising for a particular product version or the current process status.

Distributed information systems are the basis for cyber physical (production) systems and industrial internet of things. Here, distributed sensors and actuators are networked and information flows are linked in order to allow companies to operate flexibly. Corresponding intelligent algorithms and decision support enable the adaptation of the production to continuously evolving environmental conditions (see Sensing, Smart & Sustainable (S ^ 3) Enterprise).

The goal of flexible yet efficient and effective production – in terms of resilience, punctuality, responsiveness, productivity, resource conservation, etc. – requires that decision makers (a) have access to distributed data, information, knowledge and expertise, these elements are interoperable, and (b) a global overview can be created to do a holistic evaluation.

The networking of machines, software, employees, suppliers, and customers has long been a reality. Unfortunately, however, the design and engineering of software for modular socio-technical production systems-of-systems repeatedly reaches its limits.

In order to make a contribution to achieving these visions, the PROFACTOR FPS team is conducting research on the following topics with the aim of making production systems more flexible.

  • Enterprise Application Integration and Cyber Physical Systems and Industrial Internet of Things
  • Semantic Data Models and Data Integration & Analysis / Business Intelligence
  • Model-driven information systems and modelling for documentation and knowledge management
  • Discrete event simulation to understand complexity and to plan dynamic systems.
  • Dynamic Rescheduling and Flexible Job Shop Scheduling
  • Shop Floor Middleware and Architectures
  • Flexible, adaptive production through human-robot teams together with the PROFACTOR Robotics team
  • Middleware and domain specific Languages for distributed information systems
  • Modelling of production control using approaches like holonics and multi agent systems
