Opis:
Within 200 years since the industrial revolution manufacturing systems have often changed their faces. Emerging nations, new markets, new inventions and the changing needs of the society forced them to adapt. Until today, the arising challenges are immensely diverse: highly individualized products, decreasing manufacturing time, limited resources and critical ecological footprints are only a few of them. Oftentimes solutions for these issues and other future requirements can be found by interrogating nature. Applying knowledge of biological principles to industrial manufacturing processes is recently referred to as "biological transformation of manufacturing systems". Hereby three levels of a biological transformation are introduced, starting from inspiration over integration to the interaction of biological and technical systems. The paper illustrates the idea of biological transformation with specific examples for each level. On the inspiration-level the design of manufacturing systems with elements of natural ecosystems is described. Thus flexibility is increased, material cycles are closed and waste will be reduced. Furthermore the integration-level is illustrated by the use of microorganisms in cutting fluids. Finally, evolutionary computing within an automatic joining cell is shown as an example for the interaction-level.

Opis:
The introduction of CIM (Computer Integrated Manufacturing) systems in the 1980s, aiming at integrating automatic workstations into fully automated factories, was not successful. The root causes of this failure were that the subsystems to be integrated were not suitably designed for easy integration into a larger system. This situation stimulated the authors to embark on a research programme on ‘design for the unexpected’. It defined how subsystems have to be designed so that integration into larger systems becomes easier and how such an integrated system can be controlled so that it can cope with change and disturbances. In the paper, the design principles and salient features of holonic manufacturing systems (HMS) are outlined. The PROSA reference architecture, defining the basic structure of any HMS, is described. It is further explained how coordination and control of the HMS is achieved by a holonic manufacturing execution system (HMES), based on the combination of the PROSA reference architecture and a biologically inspired Delegate Multiagent System (DMAS). Finally, the power and universality of the PROSA/DMAS system is demonstrated by some case studies from manufacturing, robotics and open air engineering.

Opis:
Rozwój systemów produkcyjnych oraz stały wzrost oczekiwań klientów wymaga od firm coraz szerszego wprowadzania systemów nadzorujących procesy wytwórcze, stan maszyn oraz jakość produktów i historię ich wytwarzania. Monitorowanie procesów, maszyn i produktów, jest technicznie możliwe za pomocą coraz bardziej udoskonalanych systemów wykorzystujących zawansowane metody pomiarowe, algorytmy przetwarzania danych oraz wsparcie układów wykorzystujących tzw. sztuczną inteligencję. Jednakże wprowadzenie powszechnego nadzoru nad całymi procesami, kluczowymi maszynami i wszystkimi wyrobami wymaga szybkiego przetwarzania bardzo dużej liczby danych. Dodatkowo system taki musi być zintegrowany z funkcjami sterującymi. Implementacja zintegrowanego systemu monitorowania na bazie powszechnie stosowanej architektury klient-serwer wymagałaby budowy skomplikowanego, drogiego i mało elastycznego systemu. W artykule przedstawiono badania prowadzone nad opracowaniem zintegrowanego wieloagentowego systemu monitorowania wytwarzania realizowane na Politechnice Warszawskiej w Zakładzie Automatyzacji Obrabiarek i Obróbki Skrawaniem.
Continuously growing international competition in manufacturing sector force companies to reduce costs, at the same time rapidly increase complexity of products and quality requirements. Continuous development of manufacturing systems and increase of customer expectations requires implementation of advanced control and monitoring systems. To meet growing requirements production process should be controlled on all steps. Systems of direct control of manufacturing system, manufacturing cells, machines and performance of orders should be used. Such a system should allow for monitoring of all steps of production process according to requirements of Life Cycle Management (LCM). In article are pointed main aspects of a distributed multiagent shop floor control and monitoring system developed at Warsaw University of Technology.

Opis:
Przemiany zachodzące w gospodarce w skali makro determinują możliwości rozwoju firm produkcyjnych, co z kolei powinno wpływać na rozwój kierunków specjalizacji naukowej badań prowadzonych w danym kraju. Kluczowym procesem determinującym zmiany zachodzące w szeroko pojętych procesach produkcyjnych jest stale postępująca globalizacja, w jej wyniku firmy z krajów wysokorozwiniętych przenoszą najbardziej kosztochłonne fragmenty procesów produkcyjnych do krajów niskokosztowych. Sytuacja ta nakłada się na postępujące zmniejszanie zatrudnienia w sektorze produkcji, co z kolei wpływa na tworzenie się nowego modelu społeczeństwa, zwanego społeczeństwem postindustrialnym. Wymienione procesy skutkują głębokimi zmianami w procesach produkcyjnych, podlegają one dekompozycji i fragmentaryzacji, w wyniku outsourcingu i offshoringu najbardziej kosztowne elementy procesu przynoszone są do krajów niskokosztowych. W rezultacie w najbardziej rozwiniętych krajach wysokokosztowych następuje koncentracja produkcji o wysokiej wartości dodanej, natomiast w krajach o niskim koszcie wytwarzania następuje koncentracja najbardziej kosztochłonnych fragmentów procesów produkcyjnych. Sytuacja ta wpływa na zmianę gospodarczej mapy świata. Znajomość zmian zachodzących w gospodarce powinna mieć kluczowe znaczenie w określaniu kierunków badań prowadzonych w danym kraju, w tym również w Polsce.
Economy changes determine production company's development, it should influence on the direction of research in a particular country. The main process forcing changes in the economy is a globalization. As a result of it companies from developed countries move costly production to low cost countries. It results fragmentation of the production process and concentration of the most profitable production in developed countries. Such trends influence on changes of economy map of the whole World. In the article an analysis of trends in the manufacturing process organization is done. A particular stress is put on globalization, segmentation of production process and innovation.

Opis:
Innovative production techniques require an efficient utilization of human, material and energetic resources to ensure competitive manufacturing positions. The aim of modern industrial production processes is to provide products with a higher added value in a shorter time-to-market. On the other hand, shorter life cycles of products are contrary to the necessity of expanded service time of manufacturing systems. Moreover, the whole life cycle of products is accompanied by customer related service provisions. Flexible and adaptive as well as self-organising means of production are a considerable key to solve this conflict of objectives. Here, man with specific technological knowledge has to be integrated with it's permanently newly defined role in production. This paper presents production technology related new developments and strategies to fulfil the requirements of sustainable manufacturing.

Opis:
Novel concept of monitoring systems integration, reference models and test application for manufacturing are presented in the paper. Research results are an answer for industry needs for development of IT solutions that will allow to integrate information flow in production systems. The idea of standalone advanced monitoring devices connection with Shop Floor Control, MRP/ERP and machine operators is discussed. The concept of monitoring systems integration has been formally described by reference models. They corresponds with original multilayer data structure proposed on the base of data tree. Data model allows to describe orders, products, processes and to save monitoring results. Both kind of models has been the base for implementation of the integrated monitoring system demonstrator. The demonstrator developed in the frame of research was built on the base of multiagent technology. It allows to keep high flexibility and openness of the system, as well as easy implementation of various intelligent algorithms for data processing. Currently, an application of integrated monitoring system for real production system is developed. The main problems and future development of monitoring integration in discrete production are presented and discussed in the article.

Opis:
In many discourses, popular as well as scientific, it is suggested that the "massive" use of Artificial Intelligence (AI), including Machine Learning (ML), and reaching the point of "singularity" through so-called Artificial General Intelligence (AGI), and Artificial Super-Intelligence (ASI), will completely exclude humans from decision making, resulting in total dominance of machines over human race. Speaking in terms of manufacturing systems, it would mean that the intelligence and total automation would be achieved (once the humans are excluded). The hypothesis presented in this paper is that there is a limit of AI/ML autonomy capacity, and more concretely, the ML algorithms will be not able to become totally autonomous and, consequently, the human role will be indispensable. In the context of the question, the authors of this paper introduce the notion of the manufacturing singularity and present an intelligent machine architecture towards the manufacturing singularity, arguing that the intelligent machine will always be human dependent. In addition, concerning the manufacturing, the human will remain in the centre of Cyber-Physical Systems (CPS) and in Industry 4.0. The methodology to support this argument is inductive, similarly to the methodology applied in a number of texts found in literature, and based on computational requirements of inductive inference based machine learning. The argumentation is supported by several experiments that demonstrate the role of human within the process of machine learning. Based on the exposed considerations, a generic architecture of intelligent CPS, with embedded ML functional modules in multiple learning loops, is proposed in order to evaluate way of use of ML functionality in the context of CPS. Similar to other papers found in literature, due to the (informal) inductive methodology applied, considering that this methodology does not provide an absolute proof in favour of, or against, the hypothesis defined, the paper represents a kind of position paper. The paper is divided into two parts. In the first part a review of argumentation from literature in favour of and against the thesis on the human role in future was presented, as well as the concept of the manufacturing singularity was introduced. Furthermore, an intelligent machine architecture towards the manufacturing singularity was proposed, arguing that the intelligent machine will be always human dependent and, concerning the manufacturing, the human will remain in the centre. The argumentation is based on the phenomenon related to computational machine learning paradigm, as intrinsic feature of the AI/ML1, through the inductive inference based ML algorithms, whose effectiveness is conditioned by the human participation. In the second part, an architecture of the Cyber-Physical (Production) Systems (CPPS) with multiple learning loops is presented, together with a set of experiments demonstrating the indispensable human role. Finally, a discussion of the problem from the manufacturing community point of view on future of human role in Industry 4.0 as the environment for advanced AI/ML applications is registered.
