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 systems for decentralised and distributed socio-technical systems is reaching quite often its limits. PROFACTOR researches and develops infrastructure and algorithms for distributed information 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 systems. Here distributed sensors and actuators are networked and information flows linked to enable an adaptive production system, allowing companies to react flexible.

The goal of optimal and adaptive production networks – in terms of resilience, punctuality, responsiveness, productivity, resource conservation, etc. – requires that you have access to distributed data, information, knowledge and expertise, and these elements can be linked to each other.

PROFACTOR’s DIS team uses multi-agent-systems, holonic systems and actor-based models and combines distributed artificial intelligence approaches with research in interoperability. Overall goal is the design and engineering support of plug & produce-enabled self-optimising socio-technical evolving systems.

Projects

Overall objective of this project is to research approaches for a distributed optimisation algorithm for dynamic job shop scheduling problems in massively distributed, agile production environments with stochastic properties. The research software prototype to be developed will be based on mathemati...+
