Organizational Integration of Enterprise Systems and Resources: Advancements and Applications

Abstract
The new (e)commerce/(e)business paradigms forced enterprises to undertake important transformations and reorganizations. It happened with the web and will be repeated in the Cloud and social networks, following Eric Schmidt's (Google CEO) thoughts, "better thinking now on WWC - World Wide Computer, that is, what is behind u-commerce, ubiquity". The tourism is no more only a traditional commercial activity but ever more social- and information-oriented. The tourism services need to be effective to be aligned with tourist requirements. The globalization and easy access allows tourists to change their plans constantly. Dynamic services reconfiguration and resulting impact on their information systems need to be supported. The theme here presented explores new tourism services requirements as the ubiquity and dynamic reconfiguration, new brokering mechanisms, and reliable integration processes, and humanto-human synchronous collaboration allow the natural involvement of the tourist on the co-creation of his activity plan with other agents (humans). © 2012, IGI Global.

Abstract
Purpose: The aim of this paper is to analyze international and national research and development (R&D) programs and roadmaps for the manufacturing sector, presenting how agile and lean manufacturing models are addressed in these programs. Design/methodology/approach: In this review, several manufacturing research and development programs and roadmaps - national programs from the USA and Canada, and international programs from the European Union and from one international organization - are reviewed. Findings: The major finding of this review is that the main concerns in agile manufacturing, as highlighted in these programs, are networks, supply chain and product/service customization, and lean manufacturing's inclination towards achieving better cost efficiency. Although the lean manufacturing approach has been considered in many past and present programs, analysis of the most recent programs shows a greater priority is given to the agile manufacturing approach. The path towards sustainable manufacturing is delineated by pro-active attitude and action towards customers. Research limitations/implications: The study analyzes two national R&D programs from the USA, one international program from the European Union, three international roadmaps from the European Union, one business plan from Canada and one international roadmap from the global organization Intelligent Manufacturing Systems. Practical implications: The findings of this paper are intended to help managers, researchers and practitioners from the manufacturing sector to enhance their understanding and define suitable strategy for their organizations' sustainability and identify suitable manufacturing path with respect to agile and lean philosophies. This study could also help academics in defining course curricula for students more coherent with the R&D policies and/or requirements towards sustainable manufacturing with respect to agile and lean philosophies. Originality/value: There are reviews comparing agile and lean manufacturing paradigms, but there are no reviews about how the two manufacturing concepts are addressed in manufacturing R&D programs and roadmaps. © Emerald Group Publishing Limited.

Abstract
In transition from classical/traditional to modern manufacturing systems, a number of key improvements have occurred, including the ability to control a machine remotely, over Internet. The past approaches on implementing a remote control system have mostly focused on the remote controlling technology and much less on organizational aspects. The proposed work is focused on communication functionality as one of the key organizational aspects. This paper discusses a prototype implementation of communication functionality in remote control of machine tools, considering communication as an intrinsic organizational issue, aiming at improving the effectiveness of manufacturing systems integration.

Abstract
This paper proposes a new integrated architecture for advanced manufacturing management with a Ubiquitous Management System (UMS) and a collection of adequate features to sustain it, where pragmatics on collaboration mechanisms prevails. The Market-of-Resources repository and its advanced brokering process will enable reliable interoperability, services dynamic packages and reconfiguration, as well as the (co-) management of production process, regardless information systems and using real-time collaboration mechanisms. This article contributes for building a logical model for UMS as well as an UML formalization for its supporting architecture

Abstract
In the last few years, the industrial, scientific, and technological fields have been subject to a revolutionary process of digitalization and automation called Industry 4.0. Its implementation has been successful mainly in the economic field of sustainability, while the environmental field has been gaining more attention from researchers recently. However, the social scope of Industry 4.0 is still somewhat neglected by researchers and organizations. This research aimed to study Industry 4.0 and sustainability themes using data science, by incorporating open data and open-source tools to achieve sustainable Industry 4.0. To that end, a quantitative analysis based on open data was developed using open-source software in order to study Industry 4.0 and sustainability trends. The main results show that manufacturing is a relevant value-added activity in the worldwide economy; that, foreseeing the importance of Industry 4.0, countries in America, Asia, Europe, and Oceania are incorporating technological principles of Industry 4.0 in their cities, creating so-called smart cities; and that the industries that invest most in technology are computers and electronics, pharmaceuticals, transport equipment, and IT (information technology) services. Furthermore, the G7 countries have a prevalent positive trend for the migration of technological and social skills toward sustainability, as it relates to the social pillar, and to Industry 4.0. Finally, on the global scale, a positive correlation between data openness and happiness was found.

Abstract
The evolution of society can be related to industrial revolutions. Revolutions are disruptive and transformative phenomena that change and interact with several systems. Industrial revolutions depend on changes in scientific, and mostly technological, paradigms and require people's participation. They are not only created with individual political intentions, because they are collective and complex systems. The expression Industry 4.0, created in Germany in 2011, denotes the so-called fourth industrial revolution. The question considered in this paper is whether Industry 4.0, as the fourth industrial revolution, is effectively underway or is it still only a vision of the future? This article analyses, from the point of view of the science of complexity, the transformations and the relations of industrial systems with other selected systems. It was made through fractal analysis using indicators of four countries, namely, United Kingdom, United States of America, Germany and China. Considering the evolution of population growth, Gross Domestic Product per capita, communication technologies and intellectual property, the results of the analysis show that the factor that stands out is the protection of intellectual property. The analysis of the previous indicators showed that it is not possible to claim that the fourth industrial revolution is underway, implying that Industrial 4.0 may stil be a vision of the future. The results obtained can not be considered conclusive and more research is needed.
