In recent years, manufacturing companies have entered a new era in which all manufacturing enterprises must compete in a global economy. To stay competitive, companies must use production systems that only produce their goods with high productivity, but also allow rapid response to market changes and customers’ needs. The emerging new paradigm of inter-firm relations involving both cooperative and competitive elements, called co-opetition, seems well face this issue. The chapter proposes a multi agent architecture to support different coordination policy in an electronic co-opetitive network in which plants are willing to exchange productive capacity. An innovative approach based on cooperative game theory is proposed in this research and its performance is compared with the prevalent negotiation approach. A discrete event simulation environment has been developed in order to evaluate the related performances. The case in which no relation exists among plants has been considered as a benchmark. The obtained results show that the proposed approach outperforms the negotiation mechanism form many point of view.

And Performance

To cope with high levels of complexity, competition and change requirements, manufacturing enterprises (MEs) need to continuously improve their process and resource system performances. Enterprise Modelling (EM) is considered a prerequisite for enterprise integration and performance improvement because it can be used to capture relatively enduring knowledge about any specific business environment in which production systems will be deployed. With this prerequisite in mind, EM principles were deployed to capture and develop ‘static’ models of an SME. This provided detailed descriptions of enterprise production operations and their precedence relationships. A discrete event simulation tool was then used to develop time dependent ‘dynamic’ models of selected process segments of the specific case Enterprise Model. This allowed the computer execution of alternative production system designs to be assessed under SME specific changing scenarios and enabled suggestions for potential improvements to be made.

Many studies in research deal with optimizing emergency medical services (EMS) on both the operational and the strategic level. It is the purpose of this method-oriented article to explain the major features of “rule-based discrete event simulation” (rule-based DES), which we developed independently in Germany and Switzerland. Our rule-based DES addresses questions concerning the location and relocation of ambulances, dispatching and routing policies, and EMS interplay with other players in prehospital care. We highlight three typical use cases from a practitioner’s perspective and go into different countries’ peculiarities. We show how research results are applied to EMS and healthcare organizations to simulate and optimize specific regions in Germany and Switzerland with their strong federal structures. The rule-based DES serves as basis for decision support to improve regional emergency services’ efficiency without increasing cost. Finally, all simulation-based methods suggest normative solutions and optimize EMS’ performance within given healthcare system structures. We argue that interactions between EMS, emergency departments, and public healthcare agencies are crucial to further improving effectiveness, efficiency, and quality.

This paper studies conflicts from a process-algebraic point of view and shows how they are related to the testing theory of fair testing. Conflicts have been introduced in the context of discrete event systems, where two concurrent systems are said to be in conflict if they can get trapped in a situation where they are waiting or running endlessly, forever unable to complete their common task. In order to analyse complex discrete event systems, conflict-preserving notions of refinement and equivalence are needed. This paper characterises an appropriate refinement, called the conflict preorder, and provides a denotational semantics for it. Its relationship to other known process preorders is explored, and it is shown to generalise the fair testing preorder in process-algebra for reasoning about conflicts in discrete event systems.

The purpose of this work is to provide information on the development of the infrastructure of the African economy. The study provides statistics on African regions and industries. This article focuses on the forms of economic and social infrastructure, and directs to determine the share development infrastructural in Africa. The Africa has entered an era of devastating change this study shows that with the unfolding economic downturn in the northern economies that have traditionally dominated the global economy. The article provides empirical evidence on how the industrial sectors developed from an economic point of view. The authors believe that infrastructure affects output and productivity directly as a contribution to the production function of other sectors and as part of GDP formation. The article discusses the development of infrastructure for the period 1999-2019 without more detailed dynamics. It also does not explain the main topics developed by the authors. The work provides knowledge on how investments are developing in Africa, how industries have developed, and what is the role of each infrastructure sector in this development. It also shows how different areas of infrastructure work with different successes in creating new paths in the African economy.

The Right

The purpose of the research is to formulate the general guidelines for the transformation of human rights as a result of global threats. The methodological framework was the methods of comparative legal research, which showed the general trends in the development of the human rights legislation under the influence of global threats. By the example of the responses of states to the terrorist attacks that occurred on September 11, 2001, it is shown how legislative innovations expanding the powers of law enforcement agencies and special services have led to the revision of the content of such basic human rights as the right to privacy and/or the right to personal inviolability. Highlighted is the concept of the “war on terror” (formulated by the United States President in 2001), which allows terrorists to be treated as representatives of a belligerent but without providing any international guarantees enshrined in the provisions of the international humanitarian law. The consequences of the introduction of biomedical technologies, that are aggressive towards humans, are presented, namely the creation of chimeric organisms that contribute to blurring the interspecific boundaries; creation of a genetically modified organism – human embryo; the development of an artificial uterus capable of bearing a human fetus practically from the time the male and female reproductive cells join. The results consist in the identified trends in the development of legal institutions, such as the formulation of new human rights often replacing or distorting the content of basic recognised human rights enshrined in the key international documents and constitutions of the countries of the world; bypassing the legal prohibitions established over the past decades by introducing relativism and assessing any situation from the point of view of the conditions for its occurrence. The novelty of the research lies in the authors’ position and is formulated as follows: the modern system of human rights is facing a serious crisis. Failure to effectively respond to symbolic challenges and threats is one of the factors necessitating the need for monitoring many regulatory documents. But a significant reason for the backlash also lies in the fact that we are at the turn of an era when technology shows humanity the possibility of correcting the very nature of Homo sapiens.

Abstract. The fatty acid (FA) composition in the intramuscular fat (IMF) of the musculus longissimus dorsi (MLD) of Ile de France purebred lambs in two different production systems in Slovakia was evaluated using gas chromatography. In the first production system, lambs and ewes were assigned to pasture without access to concentrates (P). In the second system, lambs and ewes were confined indoors with hay/silage and access to concentrates (S). An analysis of variance with the following factors was employed: production system, sex, and production system–sex interactions. The proportions of arachidonic, eicosapentaeonic, docosapentaeonic, and docosahexaenoic FAs, i.e. long-chain polyunsaturated FA (PUFA), were significantly higher in P lambs (1.83, 0.82, 0.92, 0.29 g 100 g−1 FAME, respectively) than in S lambs (0.45, 0.14, 0.30, 0.09 g 100 g−1 FAME, respectively). The proportions of conjugated linoleic acid (CLA), n-6 PUFA, n-3 PUFA, and essential FA (linoleic and α-linolenic) were also significantly higher in P lambs (2.10, 8.50, 4.55, and 8.80 g 100 g−1 FAME, respectively) than in S lambs (0.65, 3.27, 1.50, and 3.64 g 100 g−1 FAME, respectively). The proportions of palmitic acid and myristic acid as important individual saturated FAs (SFA) were significantly higher in S lambs (28.51 and 8.30 g 100 g−1 FAME, respectively) than in P lambs (21.80 and 5.63 g 100 g−1 FAME, respectively). The proportion of all SFAs was also significantly higher in S lambs (57.87 g 100 g−1 FAME) than in P lambs (48.70 g 100 g−1 FAME). From a nutrition and human health point of view (i.e. higher proportions of PUFA, CLA, and essential FAs and lower proportions of SFAs), meat from P lambs was found to be more favourable and would be more highly recommended for consumption.

Post-Fordism, with its evolution towards immaterial production in the areas of information, knowledge and affective, creative commerce, foregrounds design as a central, enabling activity. If this enablement finds particular application in cities of the Global North, it testifies to a shift in the geopolitical distribution of productive agency and application of international labour, one that sees industrial activities ‘reassigned’ to the Global South, leaving cities of the variably de-industrialised countries to develop cultural, symbolic, and creative economies. This paper examines the nature of urban place and the work regimes practised there consequent to these economies. It argues firstly for ‘cityness’ in these context to be understood as a creative urban factory – a place where older managerial and organisational techniques applied to factory environments in the service of high productivity are recalibrated and diffused across the entirety of urban territories. Secondly, the paper links the productivity of the creative urban factory with a biopolitical makeover of cities themselves, seeing in an optimisation of productive capacity a situation where the entirety of living labour is taken up and commoditised via the production of ever-customised lifestyles and identities. A raft of new identifying subject and worker categories emerge that exceed or elude the older class identifications, and with it, a certain potential to collectively counter the exploitation inherent post-Fordist work. While exploring the possibility of new identifying collectives – what Hardt and Negri have referred to as the multitude – the paper makes an argument for design itself to be a key medium for rethinking and re-enacting collective agency. As the harbinger of new forms of user participation and co-operative processes that are, by way of emerging technological tools, open, evolving, ad hoc, reflexive and customisable, design practice increasingly must contend and adapt to forms of de-professionalisation. Rather than seeing in this adaption a demise in profession position, the new possibilities appearing in design point to a low-tech, yet digitally-driven enabled, re-politicisation of design and creativity, one better able to contend with the strictures of the urban creative factory.
