“…The main aim of AML is to join engineering tools from different domains such as; process control engineering, mechanical plant engineering, electrical design, process engineering, robot programming, PLC programming, HMI development etc. In the following, [14] proposed an AML model that makes use of existing AML concepts to formalize the use of 'Plug-and-Produce' components, while enabling the next generation of CPS. This is achieved by the definition of new libraries within AML to support the definitions such as: 'Skill Requirements', 'Skills' and 'Skill Recipes'.…”

“…However, the previously proposed AML model did not consider the process executions but focused more on establishing the relationships between the PPR elements of the model. In this sense, this paper focuses on using the existing AML model [14] that establishes the relationships between the PPR domains to define a new process execution process that can be used for enabling high performance production and enable fast system adaptations.…”

“…To deliver a solution for this one needs to establish the process execution model in the wider CPS models, which can be used to drive the execution process which will be orchestrated by the MSB. This paper focuses on using an existing AML model [14] that provides all the PPR relationships, and incorporate a solution that supports high performance process executions through clear decoupling of system operation and optimization. The details regarding the structure and the contents of this solution will be discussed in the next section.…”

“…The vision is to deliver production systems that adapt to deal with varying production demands, without compromising its operational performance. In this direction, AML has been identified as the prime candidate for modelling, as it that allows the integration of current legacy systems with other tools [14]. AML enables the self-description of 'Plug-and-Produce' devices, which can include both physical and functional information.…”

“…Another main motivation towards the use of AML is that it provides the detailed relationships between the PPR domains, which is crucial to this work. Towards this end, an existing AML model [14] has been used to establish these PPR relationships. The definition of assembly product in AML provides the relationships between all the available 'skill recipes' that can be used to fulfill its 'skill requirements'.…”

Assembly systems today are facing significant pressure to deliver high performance process executions, while being responsive to the fluctuating market demands. However, the implementation the trending Cyber Physical Systems concepts via 'Plug-and-Produce' devices produces some communication overheads. In this direction, the openMOS project aims to decouple the elements that are responsible for adaptation and general operations of the system. This allows the system to have two parallel processes. Towards this end, the priority is to deliver high performance process executions, while the other process focuses on delivering the required agility. The focus of this work is narrowed down to the development of task execution tables that guarantees high performance process executions. In this direction, the definition of task execution table is based on an existing AutomationML (AML) model that highlights the explicit relationships between the Product, Process and Resource (PPR) domains. A new decisional attribute has been added to the existing 'Skill' concept, which provides the flexibility to incorporate eventbased process alternatives. An insight description on how the system handles process executions during run-time failures is also provided. Finally, this paper illustrates the run-time implementation of the execution table with a help of an industrial case study that has been used for a demonstration activity within the openMOS project.The reported work is a part of the openMOS project partially funded by the European Commission as a part of the EC-H2020-IA (GA 680735).

To face the major challenges posed by the increasing product variants with shortening life cycles and fluctuating market conditions, modular and adaptable assembly systems are used. Their strong dependency on software creates a new void in the planning and implementation processes of these assembly systems. Usually, the programmer fills this void based on his knowledge, which leads to frequent and large adaptations of the code base. This is rather counter-productive. To address this challenge, we developed a generic user-friendly graphical API (Application Programming Interface) for a process owner in our previous work (Müller et al, Proc CIRP 81:730–735, 2019, [1]). This API can describe any assembly system and the associated task and is used to get the boilerplate code needed to execute the process on a programmable logic controller (PLC)—the standard hardware used in the industry. In this paper, the virtual description of an assembly system used by the API is extended to include a goal-oriented task description by defining the process and the structure. We believe that this extension provides the proper abstraction needed by the process owner. In addition, this extension significantly reduces the modeling effort.

In the Industry 4.0 area, there is an increasing demand for highly customized products in small batch sizes. Final assembly operations are frequently targeted to embed flexibility and compensate for the growing manufacturing uncertainties. Therefore, an adequately designed and operated flexible assembly workstation is crucial. Converting the flexibility needs into design and operational decisions requires versatile formal models delivering generic descriptions of needs and capacities. Skills form the central connector between products, processes and resources. Here, a skill-centered model for describing resource activities, the related production needs and flexibility impacts is introduced. The model fits both plug and produce and design optimization settings and goes beyond current skill-based modelling by offering a framework which, by design, does not limit the applications and easily adapts to the desired level of detail. One key strength is its ability to combine abstract and executable skills. Next to the product-action skills, also assistive skills related to operator support, parts storing, ergonomics etc. can be easily modelled. The use of the model is illustrated by an example based on an industrial use case from Flemish industry.
