We study a collaborative scheduling problem where the dominant manufacturer (DM) outsources several processes to collaborative manufacturers (CMs). We consider multiple types of products defined by different collaborative production networks which may share some common CMs. The DM assigns the orders to the CMs and coordinates the production scheduling among the CMs. We analyse a practical order-merging strategy which combines a subset of same-type orders throughout the production aming at the cost benefit by continuous processing. Such a strategy is easy to implement but may increase the scheduling cost because of increased deviation between the completion time and the required delivery window of some orders. To this end, a heuristic algorithm based on a learning mechanism and ant colony optimisation is proposed for solving the collaborative scheduling problem under the order-merging plans. Simulation case study was carried out to compare the costs under different merging options. We conclude that merging more orders could lead to a better cost in a few cases, and the overall system performance is more sensitive to the merging schemes when the network capacity is tighter due to disruption. Our study provides an effective solution approach and managerial insights for collaborative scheduling problems with practical order-merging strategies. [ABSTRACT FROM AUTHOR]

In order to optimize the structural performance of the heavy truck drive axle and realize the market supply goal of the whole axle lightweight, the corresponding research is carried out based on CAE/CAM technology. Using the systematic layout thinking, the mathematical model is scientifically built, a complete lightweight design axle is formed through CAE simulation analysis and CAM collaborative production, and the prototype test is conducted. The results show that the weight of the whole axle after the lightweight design is relatively reduced by 12.7% and the transmission efficiency is more than 95% on the premise of meeting the key performance parameters such as noise limit and B10 life. This design method and thinking can provide reference ideas for the improvement of other parts of heavy trucks, especially in the field of the lightweight research, and it would have great application and promotion prospects.

The traditional mode of cooperation between enterprises still suffers from major problems, including data privacy leakage, data falsification, and inefficient collaboration in data sharing. These challenges make it difficult for enterprises to ensure that their cooperative suppliers adopt sustainable practices in standards identification and operation processes. This paper proposes a "Value–Standard–Process" collaborative framework for blockchain-based enterprise data governance that helps ensure a high degree of data security, a high reliability of collaborative tasks, and a high transparency of value transformation. First, this paper proposes a new collaborative mode for blockchain-based manufacturing in the sharing economy, including the non-linear dynamic evaluation and value balancing mechanism of data with multiple attributes, a trusted data governance mechanism for blockchain-based manufacturing, and a smart contract generation mechanism for value-driven collaboration. Second, this paper explains these three components and the implementation of the overall framework. Third, this paper verifies the applicability and achievability of the proposed framework through experiments. Establishing the value-driven multi-level blockchain-based collaboration mode facilitates the effective flow of production factors and promotes trust in the digital economy of sustainability.

Digital platforms are a primary means of communication in society. Public libraries play an empowering role in these processes, strengthening citizens’ digital competences. This raises questions about what democratic processes the digital technology is made to enable. The study investigates how a Swedish Digital Library (DL) is envisioned and organised within a national digitalisation strategy. Qualitative methods are used, and a theoretical democracy framework is developed and used together with the concepts of education and Bildung in the analysis. Four empirical themes are identified. The analysis centres on tensions related to horizontality and hierarchy, and Bildung and sociality. The DL vision is dominated by a hierarchical and instrumental educational vision that connects to representative democracy. A subordinated social and pedagogical vision of inner motivational drives and partial forms of sharing, connected to deliberative and semi-participatory democracy forms, exists, mostly in the form of some cherry-picked Web 2.0 discourses.

The upcycling trend has received renewed attention in the past few years due to growing concerns for the environment related to increased resource consumption and waste volumes. Indeed, cities across the world are supporting resource upcycling initiatives by establishing do-it-yourself (DIY) repair cafes and makerspaces as a means to transform societies towards sustainable development. However, the sustainability potential of such upcycling initiatives is unknown due to the lack of theoretical frameworks. This research aims to explore the direct and indirect social, economic, and environmental implications of upcycling activities at DIY bicycle repair studios. The main objectives of the study were to: (1) examine the upcycling activities in these studios that contribute to slowing and closing the material cycles, (2) explore the behavioral implications of the users of these maker spaces in the context of environmental sustainability, and (3) propose ways to evaluate the broad environmental impacts of the upcycling activities at these studios. The objectives were explored in three case studies—2 in Sweden (Cykelköket in Malmö and Bagarmossens Cykelköket in Stockholm) and 1 in Switzerland (Point Vélo, Lausanne). Semi-structured interviews, user surveys, and participant observation methods are employed to collect qualitative, and quantitative data to formulate a systemic exploration of major activities and socio-economic exchanges at these repair cafes. The study identified multiple social, economic, and environmental impacts of upcycling activities and represented them in causal loop diagrams. Based on this, a framework for evaluating and governing the overall sustainability potential of upcycling activities is proposed. [ABSTRACT FROM AUTHOR]

Abstract: The shales in the 2nd Member of Shanxi Formation in the east margin of the Ordos Basin were deposited in a marine-nonmarine transitional environment during the Permian. Based on the recent breakthroughs in the shale gas exploration and theoretical understandings on the shale gas of the study area, with a comparison to marine shale gas in the Sichuan Basin and marine-nonmarine transitional shale gas in the U.S., this study presents the geological characteristics and development potential of marine-nonmarine transitional gas in the study area. Four geological features are identified in the 2nd Member of the Shanxi Formation in the study area has: (1) stable sedimentary environment is conductive to deposition of widely distributed organic shale; (2) well-developed micro- and nano- scale pore and fracture systems, providing good storage capacity; (3) high content of brittle minerals such as quartz, leading to effectively reservoir fracturing; and (4) moderate reservoir pressure and relatively high gas content, allowing efficient development of shale gas. The 2nd Member of Shanxi Formation in the east margin of Ordos Basin is rich in shale gas resource. Three favorable zones, Yulin-Linxian, Shiloubei-Daning-Jixian, and Hancheng-Huangling are developed, with a total area of 1.28×104 km2 and resources between 1.8×1012 and 2.9×1012 m3, indicating a huge exploration potential. Tests of the 2nd Member of Shanxi Formation in vertical wells show that the favorable intervals have stable gas production and high reserves controlled by single well, good recoverability and fracability. This shale interval has sufficient energy, stable production capacity, and good development prospects, as evidenced by systematic well testing. The east margin of the Ordos Basin has several shale intervals in the Shanxi and Taiyuan formations, and several coal seams interbedded, so collaborative production of different types of natural gas in different intervals can be considered. The study results can provide reference for shale gas exploration and development and promote the rapid exploitation of shale gas in China.

The Earth to Tables Legacies Project emerged in 2015, growing out of personal relationships, but also built on a long trajectory of participatory research, multimedia arts production and popular education. We created an intergenerational and intercultural exchange of food activists working for food justice and food sovereignty with the initial goal of producing a feature length documentary. However, the project evolved over five years to culminate in a multimedia educational package with 10 short videos and 11 photo essays, all accompanied by facilitator’s guides. A web series on the pandemic is in production and a forthcoming book is to be published in 2021. The intergenerational production team included Deborah Barndt (co-director and co-editor), Lauren Baker (co-editor) and Alexandra Gelis (co-director). In this ‘report from the field,’ the two co-directors Alexandra and Deborah look back on the process of co-producing the visual materials for the interactive website and look forward to its potential use in university classes, schools, and social and environmental justice organizations. Parts of the essay include our zoom dialogue as we revisit our process over the past five years and try to elucidate our way of working, while reflecting on the challenges of the collaborative production and use of multimedia educational tools. Note that this essay utilizes the same kind of text with hyperlinks that are featured in our website and book. The reader is encouraged to click on the links to learn more about the people and their practices as well as the concept of a non-linear multimedia educational tool and process.

After raising US$2.5 million in a Kickstarter campaign for an inexpensive Virtual Reality (VR) display, the technology company Oculus revitalized the medium through collabourative production and a reliance on the avid participation of fans to make content. This paper investigates the impact of playful labour on the diffusion of innovations (Rogers 2003). Through a platform analysis (van Dijck 2013) of the Oculus Rift and semi-structured interviews with 90 VR adopters, it reveals how a production system based on "playbour" (Kücklich 2005) both shaped perceptions of the Rift as the de facto VR device and provided access to game developers at the expense of other professions. Ultimately, these findings are emblematic of an increasingly common practice: capitalizing on the playful experimentation and expenditure of enthusiasts/consumers in the adoption of innovations within the "tech" industry.

To realize the efficient decomposition and allocation of collaborative production tasks and resources among multiple enterprises, a task decomposition and allocation model for collaborative production among multiple manufacturing enterprises is proposed in a big data environment. The model is designed for the efficient and fast processing of production information using big data technology. This study innovatively applies the 5S management method to conduct data preprocessing for a manufacturing service provider and design the operation process of data cleaning and conversion to improve the efficiency of data processing. A collaborative optimization model, based on a hierarchical model with seven levels and considering time, costs, and services, is established for the task of production to achieve a reasonable match between supply and demand. Finally, the correlation coefficients of manufacturing service providers are configured according to weight order, so that the weight order is symmetrical with that of the manufacturer. The model also engages all manufacturing service providers with different production capabilities in collaborative production. The model is proved to be scientific and effective by using a specific example. In cooperative production activities, the production tasks of small and medium-sized enterprises can be effectively allocated. It can also realize efficient cooperative production among multiple manufacturing enterprises.

Young citizens show an increasing interest for direct democracy tools and for the building of a new relationship with public administration through the use of digital platforms. The Open Data issue is part of this transformation. The paper analyzes the Open Data issue from the perspective of a spontaneous and informal group of digital activists with the aim of promoting data disclosure. The study is focused mainly on the case of a specific local movement, named Open Data Sicilia (ODS), combining traditional ethnographic observation with an ethnographic approach. The aim of the study is to detect the social pro-file of the Open Data movement activists, understanding how is it organized their network, what are the common purposes and solidarity models embodied by this type of movement, what are the resources mo-bilized and their strategies between on-line and off-line. The ODS case appears interesting for its evolu-tion, its strategy and organizational structure: an elitist and technocratic movement that aspires to a broad constituency. It is an expressive or a reformist movement, rather than an anti-system actor, with features that are similar to a lobby. The case study also shows all the typical characteristics of digital activism, with its fluid boundaries between ethical inspiration of civic engagement and individual interests

Based on the current keyword 'sharing economy', this article applies the notion of sharing to on-going changes in the TV audience market. Through in-depth interviews with TV providers and the analysis of previous research, it points to sharing activities by TV audiences as well as TV providers that represent forms of collaborative production and collaborative consumption. In detail, the article distinguishes three types of sharing activities in the audience market: distribution, interaction and audience circulation. The article emphasizes the value creation in the TV audience market through sharing activities by audiences and proposes an 'activity net of value creation' in the TV audience market to illustrate such dynamics.

Active participation of users on the Internet has not only begun to stimulate new production models, but also business models around it. Many companies are beginning to exploit competitive advantages in costs or differentiation, derived from people participation and their willingness to collaborate on various projects, which did not always have an economic return; and when this return exists is often less than required by a professional for the same work. This paper analyzes the phenomenon of crowdsourcing from both sides and the economic and social impact that it has produced during recent years. We begin with a critical approach to Internet consideration as a participative space that empowers individuals and economic agents, given that crowdsourcing foundations are on the network effect, and with a discussion about its advantages and limitations. Later, main features are structured, based on the study of different cases, in order to set three basic patterns depending on crowdsourcing shall be considered either as a business model, as an altruistic collaborative production mean or as an hybrid of the above two.

It addresses the collaborative production in the field of Information Science in Brazil, seeking to identify the authorship and characterize the formation. Production was mapped out at the National Meeting on Research in Information Science. The sample referred to the production presented in editions XIII, XIV, XV and XVI. The survey was carried out at the Benancib - Network Issues database, which indexes and stores the communications made at the meeting. In the characterization of the authorship formation, curricula were verified in the Lattes Platform of the National Council of Scientific and Technological Development and, when necessary, in the sites of the Graduate Programs recommended by the Coordination of Improvement of Higher Level Personnel. A total of 1.265 communications were recorded, of which 264 were performed individually and 1.001 collaboratively. The results point out that there are multiple formations of several areas of knowledge present in the scientific production of Information Science. [ABSTRACT FROM AUTHOR]

Propõe ao final, considerar a educação com base na pluralidade construindo novas educações.The paper focuses on the transformations of the contemporary world with the intense presence of digital information and communication technologies. It analyses what we call space-time labyrinth which characterizes the contemporary hypertextuality of the world. Based on an understanding of digital technologies, we discuss the languages associated with it and its appropriation by the youth. We analyze the production of knowledge considering the global movement of free and collaborative production of knowledge through digital technologies, based on the so-called hacker ethic. We also think about education from a collaborative perspective, emphasizing the role of digital culture as an open place for new modes of relationships and exchange of cultures, promoting new possibilities for the production of knowledge and cultures. Finally, we propose to consider education from a plurality view for the construction of new forms of education.

Neste trabalho são revistos, organizados e discutidos conceitos e estratégias em torno das formas colaborativas de produção na sociedade da informação, particularmente aqueles relacionados com o trabalho imaterial e o compartilhamento de informação. O capitalismo no seu modo de desenvolvimento informacional produz mudanças nas relações entre as formas sociais de produção e as tecnologias de informação e comunicação. A produção capitalista atual centraliza os bens imateriais a informação em primeiro lugar. O compartilhamento de informação é parte de processo de produção e, ao mesmo tempo, o seu principal produto. O compartilhamento possibilita a construção de modos de organização inteligentes e solidários, e modos de produção “não-capitalistas”. O compartilhamento produz o comum, em comum. Cria-se uma densa esfera do comum, base para uma recriação incessante. Conclui-se que as formas colaborativas de produção são particularmente importantes para que se singularizem as subjetividades e se produzam modos autônomos de vida.In this work there are reviewed, organized and discussed concepts and strategies around the collaborative production forms in the information society, particularly those related with the immaterial labour and the information sharing. The capitalism in its way ofinformational development produces changes in the relationships between the social forms of production and the technologies of information and communication. The current capitalist production centralizes the immaterial goods - the information in firstplace. Information sharing is part of production process and, at the same time, its main product. Sharing makes possible the construction of intelligent and solidary organization manners, and "no-pitalists" production manners. Sharing produces the common, in common. It grows up a dense sphere of the common, base for an incessant re-creation. It is ended that collaborative production forms are particularly important for single out the subjectivities and to produce autonomous manners of life.

RAN: Remote Area Nurseis a six-part mini-series first broadcast on the Australian Special Broadcasting Service (SBS) in 2006. Described by co-producer Penny Chapman as ‘the first screen fiction set in Torres Strait islander [sic] culture’, the series is loosely based on the work of the health centre on Masig, a tiny island in the central group of Torres Strait Islands. This article traces the working modes of the largely non-Islander production team, as they followed the guidelines and strategies laid out in SBS's ‘The Greater Perspective: Protocol for the Production of Film and Television on Aboriginal and Torres Strait Islander Communities’ (1997). In light of interplay between protocol and the production team, the article explores how a modally conventional mini-series nevertheless successfully made space for Islander collaboration, and attracted online engagement and approval from both Torres Strait Islanders and others.

The history of this research is due to concerns about the little employment of pedagogical practices and media reported an experience that provides students and teachers another look to the production of knowledge. In this research aimed to build an environment for collaborative learning supported by computer as a strategy for teaching and learning in environmental education. The bullying was the trimming done on the environmental issue as a way to discuss issues such as violence as the constitution of the subject device. We sought to develop the methodological principles of action research, which has features like the action, research and change of behavior of those involved, who collectively are involved in the action in all its phases, whose common purpose is to transform reality. The results showed that the participants use strategies that work together for collective action and participatory, demonstrating that the blog is a pedagogical tool that discusses the process of interaction and computer-mediated collaborative text production, thus contributing to the education that is transformative, critical and participatory.

Production service system (PnSS) is a new business mode where a manufacturer obtains manufacturing resources in the form of continuous production services instead of resource entities. This new mode helps reduce the setup costs and technical/financial risks of production resources while ensuring their life cycle service levels. Industrial product service system advocates the servitisation of production facilities and has evolved into a successful and mature type of PnSS. This article proposes a PnSS framework that expands the scope of production services to include component services, i.e. suppliers provide not only the component entities but also a series of services related to the components' stocking, assembling and even consuming, to their customers along the supply chain. A systematic PnSS configuration (PnSSC) methodology and the enabling platform are developed based on a newly extended analytical target cascading (ATC) method. As ATC accommodates heterogeneous sub-system integration and multi-level problem solving, the methodologies are able to address the typical challenges that a practical component service PnSSC process normally faces, such as distributed decision rights, uncertain decision structure and short decision period. Due to the similar and normally simplified configuration requirements, this methodology and platform are also both generic enough to be applied or adapted for PnSS of other production resources.

Abstract: An integrated model of supply network and production planning is proposed for the collaboration among refineries manufacturing multiple fuel products at different locations. The simulation and optimization based on the model indicate the following. The distribution costs can be reduced by relocating distribution centers as well as by reconfiguring their linkages to various markets. Moreover, the multiple fuel products manufactured need to be segregated during storage and transportation to be able to satisfy the demands of the various markets. The production planning, therefore, should be an integral part of the supply-network planning, and vice versa. Specifically, the proposed integrated model is for the nationwide supply of multiple fuel products manufactured by the individual refineries. The efficacy and usefulness of the integrated model is illustrated with an example involving three refineries and four varieties of fuel products. [Copyright &y& Elsevier]
