摘要： Manufacturing execution systems play an important role of bridging high-level enterprise functions and production or manufacturing operations. The embedded systems are usually in charge of controlling execution of the operations. Modern embedded systems have become capable of simultaneous and deterministic execution of control algorithms and IP-based communication, making it possible to create complex cyber–physical systems (CPSs), where the computational and communication resources of a device can be used directly for various control, supervisory, or monitoring functions. The complexity for defining open-knowledge-driven manufacturing execution system (OKD-MES) is in maintaining awareness of overall system state to avoid disruptive actions as various functions may be requested from a system. The problem is that obtaining such information on system state may necessitate collecting data from a number of devices, as there may not be a single data point for state information. This paper describes and illustrates an approach for designing OKD-MES on top of CPSs that controls robot workstations and conveyor-based transportation system of a pallet-based production system.

摘要： To improve the flexibility and robustness of the engineering of automated production systems (aPS) in the case of extending, reducing, or modifying parts, several approaches propose an encapsulation and clustering of related functions, e.g., from electrical, mechanical, or software engineering, based on a modular architecture. Considering the development of these modules, there are different stages, e.g., module planning or functional engineering, that have to be completed. A reference model that addresses the different stages for the engineering of aPS is proposed by the automation markup language (AML). Due to these different stages and the integration of several engineering disciplines, e.g., mechanical, electrical/electronic, or software engineering, information not limited to one discipline are stored redundantly, increasing the effort to transfer information and the risk of inconsistency. Although data formats for the storage and exchange of plant engineering information exist, e.g., AML, fixed domain specific structures and relations of the information, e.g., for automated material flow systems (aMFSs), are missing. This paper presents the integration of a metamodel into the development of modules for aMFS to improve the transferability and consistency of information between the different engineering stages and the increasing level of detail from coarse-grained plant planning to fine-grained functional engineering.

摘要： This paper presents the modular automation for reuse in manufacturing systems (modAT4rMS) approach to support the model-driven engineering (MDE) of object-oriented manufacturing automation software with regard to its usability and software modularity. With usability, we refer to the aspects’ effectiveness, efficiency, and user acceptance as defined by ISO 9241-11. The modAT4rMS notations are based on selected features from the unified modeling language (UML) and the systems modeling language (SysML), and iteratively further developed by a series of empirical studies with industrial practitioners, as well as mechatronics trainees. With modAT4rMS, an MDE approach for programmable logic controller (PLC) programming was developed with the goal to facilitate modular object-oriented programming of PLC software by improving the representation of the relationships between the structure and behavior diagram types, and by reducing the level of abstraction in the structure model. modAT4rMS notations for PLC software structure and software behavior modeling are presented and illustrated with a modeling example using a modAT4rMS editor prototype. For the evaluation of the developed notations, the results from a study with 168 participants are presented, showing the benefits of this new approach in comparison with the classic procedural paradigm (IEC 61131-3) and the domain-specific UML profile (plcML) in regard to programming performance and usability aspects. Finally, the advantages and limitations of the approach are discussed, and an outlook for further development is given.
