SOPRO - Advancements in the self-organising production

Abstract

Rising demands to smaller lot sizes and more flexibility in production processes inspired the idea of selforganising production by the use of "intelligent" parts. This is achieved by self-sustaining wireless nodesProcess-eGrains -to transfer the production control and logic from a centralised approach to a distributed logic. This paper will show the requirements in an industrial environment from an application perspective to these nodes. We present the middleware design implemented on an agent-driven architecture. Abstracting from different hardware it provides a unified interface for storing and processing information independently and locally and negotiate among each other. The application is exemplified through a part driven assembly.

User-Guided Visual Analysis of Cyber-Physical Production Systems

“…The applicability of different self-organization concepts is tested in several research projects by using prototype factories (e.g. [11][12][13]). As the implementation of such prototypes with real machinery involves considerable effort and expenses, they are therefore not meant for real scale experiments.…”

Control layer for multi-vendor industrial robot interaction providing integration of supervisory process control and multifunctional control units

“…In the research project SOPRO -Self-Organized Production -one focus is on assembly tasks [11]. The aim of selforganization with less central planning and control is realized by augmenting each entity (e.g.…”

Process Planning and Decentralised Process Control for Cybertronic Production Systems

“…Optimised configuration and proactive re-configuration of production systems Increased flexibility of production systems Decreased reaction times on failures and unexpected events In-situ load balancing of machines and production lines [1] Improved achievement of logistic KPIs (e.g. throughput time, machine utilisation) [11] By augmenting production systems with information and communication technology, the resulting CTPS will become inherently intelligent.…”

“…Rising diversity of variants, lot size zero and the demand for custom tailored products which need to be produced at mass-production costs, request for flexible production scheduling and control. To address these Industry 4.0 drivers the application of decentralised and self-organised production planning and control (PPC) methods are proposed [1]. The major focus of Industry 4.0 is the application of cyber-physical or cybertronic systems which are using the internet of things for production engineering and logistic tasks.…”
