One idea for simulation is applying artificial intelligence, in this case the method of multi-agent-systems (MAS), to simulate the inter-dependencies of different production units based on individually configured orders. Interfacing Cyber-Physical Production Systems With Human Decision Makers. 1. In manufacturing systems, technical building services (TBS) such as cooling towers (CT) are drivers of resource demands while they fulfil a vital mission to keep the production running. Despite the significant energy-efficiency potential through optimized planning and the acknowledged application potential for sophisticated simulation-based methods, digital tools for practical planning applications are still lacking. To support the planning and implementation of virtual quality gates, a morphological box is developed which can be used to identify and derive an individual approach for a virtual quality gate based on the specific characteristics and requirements of the respective manufacturing system. Cost pressure and environmental compliances sensitize facility operators for, Cyber-physical production systems (CPPS) and digital twins (DT) with a data-driven core enable retrospective analyses of acquired data to achieve a pervasive system understanding and can further support prospective operational management in production systems. That’s why our cyber physical systems (cps) allow you to test adjustments in the production process virtually, for even large-scale reconfigurations. The authors develop a planning method featuring a hybrid (discrete-continuous) simulation-based multi-criteria optimization (a multi-stage hybrid heuristic and metaheuristic method) for a metal casting manufacturer and apply it to a heat treatment process, that requires order batching and sequencing/scheduling on parallel machines, considering complex restrictions. Such manual activities can increase. Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website.

This paper discusses and defines essential elements of virtual quality gates in the context of manufacturing systems. In this contribution, we investigate the process combination of thermoforming FRTP sheets (organo sheets) and injection overmolding of short FRTP for automotive structures. To stay competitive, companies need to minimize the total cost of quality while ensuring high transparency about process–product relationships within the manufacturing system. Additionally, there is a need for case studies which prove the feasibility and give a clear assessment of benefits but also related drawbacks of CPPS solutions. All manuscripts are thoroughly refereed through a single-blind peer-review process. 2 Cyber-physical production systems research context 2.1 Definition and fundamentals CPPS classical definition [6] is widely accepted in the last few years as it exhibits well the notion of the necessary cooperation between CPS in a CPPS. Moreover, the framework is exemplified by three case studies from various industries and resulting potential are discussed. The system covers negotiations, financial transactions and agile self-organisation while employing only limited hardware resources in a near real-time environment. In the intelligent factory, ICT technologies no longer just support production processes, but are integrated into components, machines and environments that thus become intercommunicating and intelligent CPSs. 13.
