Konferensbidrag (refereegranskat)abstract
- Besides coping with the highly dynamic product and production system life cycles with ever-changing requirements, modern assembly systems also need to be user-friendly. Their modularity at fine granularity-level combined with local intelligence and a distributed control approach allows the systems to evolve together with the requirements - but their complexity would soon not be manageable from outside any more if user-friendliness was not considered a major criterion. Systems must be made to serve their users. Thanks to Self-* capabilities, systems can gain an increasingly high degree of autonomy. Diagnosis plays a particularly important role in this process.

Bokkapitel (refereegranskat)abstract
- The present work addresses the problem of shop-floor agility, presenting it as the fundamental cornerstone for true agility and responsiveness of an enterprise willing to participate in highly dynamic collaborative organizations and supply chains. Clearly, as the economic climate toughens, the exploration of the increasingly volatile business opportunities requires such complex organizations. The feasibility of the architecture proposed is demonstrated in a pilot implementation in a near-real shop-floor. Emerging web standards such as the device profile for web services were used to guarantee cross-layer/abstraction interoperability ensuring that the shop-floor reacts positively to adjustments in the supply chain.

Diagnosis on evolvable production systems
- 2007
-
Ingår i: 2007 IEEE International Symposium on Industrial Electronics, Proceedings. - : IEEE. - 1424407559 - 9781424407552 - 9781424407545 ; , s. 3221-3226

Konferensbidrag (refereegranskat)abstract
- Evolvable Production Systems (EPS) lies at the leading edge of the new paradigms currently emerging as a response to the continuously changing socio-economic challenges that modern enterprises have to deal with. Maximizing the profit under adverse market conditions is also a matter of cost cut and EPS targets this through an efficient diagnosis mechanism embedded in future production systems. Evolvable production systems goes beyond other manufacturing paradigms, and offers intelligent devices with biologically inspired behaviours, heavily dependent on self-diagnosis, self healing and other autonomous actions to ensure the systems' proper functioning and a timely response and recover from unpredictable situations.

Konferensbidrag (refereegranskat)abstract
- Service Oriented Architecture (SOA) is an emergent approach to industrial control that accompanies new industrial paradigms in the response to the continuously changing socio-economic challenges posed to modern and future enterprises. Maximizing the profit under adverse market conditions is also a matter of cost cut and the use of distributed and intelligent devices with efficient diagnosis mechanisms can help improving equipment's uptime either by reacting before a breakdown or recovering gracefully from failures.

The PRIME Semantic Language: Plug and Produce in Standard- based Manufacturing Production Systems
- 2015

Ingår i: Proceedings of the Flexible Automation and Intelligent Manufacturing Conference.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Nowadays manufacturing production systems are becoming more and more responsive in order to succeed in ahighly unstable environment. The capability of a production system to effectively and efficiently adapt and evolveto face the changing requirements – imposed by volatile and dynamic global markets – is a necessary conditionto enable manufacturing enterprises to be agile. Since the agility of a manufacturing enterprise is always limitedby the agility of its own building blocks than it needs to be spread over the whole enterprise including the operationand information technologies (OT/IT). Turning to production systems, one of the significant challenges isrepresented by the possibility to provide easy and rapid (re-)configuration of their internal components and/orprocesses. Innovative technologies and paradigms have been explored during the years that combined with theincreasing advancement in manufacturing technologies enable the implementation of the “plug and produce”paradigm. The “plug and produce” paradigm is the foundation of any agile production system, since to be agile itis inevitably required to reduce the installation and (re-)engineering activities time – changing/adapting the systemto new requirements – while promoting configuration rather than programming. Therefore, the “plug andproduce” paradigm is a necessary but not sufficient condition for implementing agile production systems. Modernproduction systems are typically known for their plethora of heterogeneous component/equipment. In this complexscenario, the implementation of the “plug and produce” paradigm implies the existence of a well-definedontological model to support components/equipment abstraction with the objective to allow interactions,collaboration and knowledge sharing between them. The PRIME semantic language specifies the semanticstructure for the knowledge models and overall system communication language.

Bio-Inspired Self-Organising Architecture for Cyber-Physical Manufacturing Systems
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The refinement in consumer's requirements and the fast paced development of socio-technical systems, are promoting, increasingly globalized markets with a high demand for fast time-to-market, sustainable, high quality and highly customized, or even personalized, low priced products. This new reality is forcing companies to change and adapt their business strategies, so that they can quickly and efficiently engage in short-window business opportunities. A critical enabler of the companies' ability to tackle these opportunities is the shopfloor and its ability to cope with change. In this sense, a number of modern manufacturing paradigms emerged, that propose a relaxation of the strictness of the control chains and new modular system designs, that tolerate a controlled and regulated unpredictability of the system behaviour, and simultaneously foster the system's autonomy, robustness, adaptability, plug-ability, evolution and self-organisation.From a structural and dynamic perspective such solutions become, therefore, close to biological systems. In fact, biological systems and their characteristics are a common analogy to express the high level design principles, of modern production paradigms. However, despite this common source of inspiration, the application of bio-inspired concepts, is often lost due to design and implementation choices, or is simply limited to heuristic approaches, that solve specific hard optimization problems.In this dissertation, a bio-inspired reference architecture for production systems, focused on highly dynamic environments, denominated "BIO-inspired Self-Organising ARchitecture for Manufacturing systems" (BIOSOARM), is presented. BIOSOARM was developed under the umbrella of Evolvable Production Systems (EPS) and aims to strictly adhere to bio-inspired principles. For this purpose, both shopfloor components and product parts are individualized and extended into the virtual environment, as fully decoupled autonomous entities, where they interact, following bio-inspired patterns, and cooperate towards the emergence of a self-organising behaviour, that leads to the emergence of the necessary production flows and consequently of the desired products. BIOSOARM, therefore, introduces a fundamentally novel approach to production, that decouples the system's operation from eventual changes, uncertainty or even critical failures, while simultaneously ensures the performance levels and simplifies the deployment, reconfiguration/adaptation and evolution procedures, enabling companies to cope with the new highly dynamic and challenging environments.

Bio-inspired self-organising methodologies for production emergence

Konferensbidrag (refereegranskat)abstract
- With the emergence of new modern manufacturing paradigms new concepts, originally from the complexity sciences started to be introduced in the manufacturing systems, rendering traditional control approaches insufficient. Therefore, new approaches were developed, supported by the modern manufacturing paradigms bio-inspired background. However, somehow along the way the physical and logical nature of the system was partially lost, leading to the convergence of approaches towards more traditional systems, 'neglecting' their bio-inspired principles. With the present work the authors aim to introduce and analyse two new different self-organising approaches that try to bring the focus of manufacturing systems, again to the bio-inspired principles. For this purpose, in the context of this work, manufacturing systems are approached from a bottom-up perspective, in an attempt to reduce the specification of the production processes to the minimum and foster the production emergence. A test case is considered, to draw initial conclusions.

Konferensbidrag (refereegranskat)abstract
- There has been an increasing interest from industry in distributed architectures since they promote a plug-and-produce and robust environment, where adaptability and fault tolerance are native. Much research has been conducted in this field mainly supported by multi-agent and service oriented technologies. Nevertheless the retrieval and visualization of information in distributed systems is a relatively unexplored area. Although the dynamic nature of the multi-agent systems allows gathering information in a prompt manner, doing so might affect the performance of the mechatronic agents. In this sense, the present paper details the architecture of a visualization tool that introduces a reliable but non-invasive approach to retrieve data from distributed platforms as well as a new way to visualize and interpret the information gathered from mechatronic based systems.

Assessing the Integration of Software Agents and Industrial Automation Systems with ISO/IEC 25010
- 2018
-
Ingår i: 2018 IEEE 16TH INTERNATIONAL CONFERENCE ON INDUSTRIAL INFORMATICS (INDIN). - : IEEE. - 9781538648292 - 9781538648308 ; , s. 61-66

Konferensbidrag (refereegranskat)abstract
- Agent-technologies have been used for higher-level decision making in addition to carrying out lower-level automation and control functions in industrial systems. Recent research has identified a number of architectural patterns for the use of agents in industrial automation systems but these practices vary in several ways, including how closely agents are coupled with physical systems and their control functions. Such practices may play a pivotal role in the Cyber-Physical System integration and interaction. Hence, there is a clear need for a common set of criteria for assessing available practices and identifying a best-fit practice for a given industrial use case. Unfortunately, no such common criteria exist currently. This work proposes an assessment criteria approach as well as a methodology to enable the use case based selection of a best practice for integrating agents and industrial systems. The software product quality model proposed by the ISO/IEC 25010 family of standards is used as starting point and is put in the industrial automation context. Subsequently, the proposed methodology is applied, and a survey of experts in the domain is carried out, in order to reveal some insights on the key characteristics of the subject matter.

Konferensbidrag (refereegranskat)abstract
- The NEMO&CODED (NEMO) project targets the development of a standard-based software infrastructure, aiming to provide the appropriate support to manage energy-related devices considering an environment where energy is generated, stored, distributed, and consumed in a rational and environmentally correct way. This paper presents and discusses the results achieved so far by the project, with special emphasis on the implementation of a web services-based wrapper to seamlessly integrate new energy sources (renewable ones) into the NEMO network. Such a wrapper relies on the adoption of two standards, namely DPWS and the IEC 61850 series. The former handles service oriented related aspects whilst the latter helps to support the interoperability of Intelligent Electronic Devices (IEDs), through the use of the Abstract Communication Service Interface (ACSI) and the Substation Configuration Language (SCL). Main problems raised and solutions found are also included in the paper as well as the future steps to be performed.
