  • WSC - Digital manufacturing: requirements and challenges for implementing Digital Surrogates
    2018 Winter Simulation Conference (WSC), 2018
    Co-Authors: Guodong Shao, Deogratias Kibira
    Abstract:

    A key challenge for manufacturers today is efficiently producing and delivering products on time. Issues include demand for customized products, changes in orders, and equipment status change, complicating the decision-making process. A real-time Digital representation of the manufacturing operation would help address these challenges. Recent technology advancements of smart sensors, IoT, and cloud computing make it possible to realize a "Digital twin" of a manufacturing system or process. Digital twins or Surrogates are data-driven virtual representations that replicate, connect, and synchronize the operation of a manufacturing system or process. They utilize dynamically collected data to track system behaviors, analyze performance, and help make decisions without interrupting production. In this paper, we define Digital Surrogate, explore their relationships to simulation, Digital thread, artificial intelligence, and IoT. We identify the technology and standard requirements and challenges for implementing Digital Surrogates. A production planning case is used to exemplify the Digital Surrogate concept.

  • the Digital Surrogate seal of approval a consumer oriented standard
    D-lib Magazine, 2013
    Co-Authors: James A Jacobs, James R Jacobs
    Abstract:

    We propose the "Digital-Surrogate Seal of Approval" (DSSOA) as a simple way of describing Digital objects created from printed books and other non-Digital originals as Surrogates for the analog original. The DSSOA denotes that a digitization accurately and completely replicates the content and presentation of the original. It can be used to express an intended goal during the planning stages of digitization and to guarantee the quality of existing Digital Surrogates. The DSSOA Criteria can be used to evaluate individual Digital objects or entire completed collections. DSSOA is independent of production technologies and methodologies and focuses instead on the perspective of consumers — including libraries that rely on Digital Surrogates.

  • Questioning ubiquitous computing
    Proceedings of the 1995 ACM 23rd annual conference on Computer science - CSC '95, 1995
    Co-Authors: Agustin A. Araya
    Abstract:

    "Ubiquitous computing is the most explicit attempt yet to move computing beyond the confines of tool usage towards a pervasive penetration of human activities, with potentially far-reaching effects." [p. 230] Araya wants to investigate where this new idea of ubiquitous computing comes from and how it fits into a history of the development of technology. The development of technology in the past centuries has only been possible thanks to the rise of what Araya calls "technical thinking": "Technical thinking [...] contributes to make technology possible and orients its development in definite directions." [p. 231] Technical thinking has led to a new way of interacting with the world: "the technical way of disclosing the world". "As a mode of disclosing it determines the way in which humans interact with the world. The seemingly infinite ways in which people go about their everyday lives are circumscribed by this underlying mode of disclosing." [p. 231] This technical way of disclosing the world is possible only within a "technical community": "In these communities, rationalized forms of action are highly predominant and an extensive use of technological artifacts and systems mediate the human-world relationships." [p. 231] The most important aspect of ubiquitous computing, as a technological development, is that is doesn't try to bring the technology to the foreground (like so many other technological developments do), but rather explicitly attempts to make the technology disappear into the background. Araya quotes Weiser, who stated that computing technologies will only reach their "full potential" when they have disappeared into the background in this way. He tries to investigate what Weiser's proposition entails: "'Immersion into the background' should be understood in two different but related senses. First, it literally means the physical integration of computing technology into the world by embedding it into tools, things, tasks, and environments. But, second, this embedding has to be accomplished in such a way that the computerized tool or thing does not 'interfere' with the activities on which it is used..." [p. 232] "Immersing computer technology into the background would achieve two important goals. First, it would facilitate the performance of tasks supported by this technology. Second, it would contribute to its widespread propagation so that 'computer access will penetrate all groups in society'." [p. 232] "Ubiquitous computing is described as a 'possible next generation computing environment in which each person is continually interacting with hundreds of nearby wirelessly interconnected computers." [p. 232, emphasis added by Araya] This leads to the notion of "ultraconnectivity" [p. 233]. What would happen when a world full of ubiquitous computing was to be realized? "The ubiquity of writing, as attested by books, signs, and billboards serves as a model for the ubiquity of computing. [...] Whereas in writing, which in this context includes the technology of paper as physical memory, 'information' is temporally and spacially constrained, the infrastructure of Ubiquitous Computing would break these constraints conferring on information and unheard-of accessibility, mobility, and processability, allowing for what we will call the ultradisseminability of information." [p. 233] "Ubiquitous computing aims not only at satisfying the need for instantaneous access to information, but it also attempts to give instantaneous access to any 'thing' including tools, books, and people, transforming them into surveillable things." [p. 233] "By integrating sensors and actors into the web of Ubiquitous Computing, it is possible to envision the so called responsive environments. By sensing people's current locations and by using information about their preferences, it is possible to adjust heat and light in buildings to satisfy their perceived needs." [p. 233] "What is then ultimately accomplished by Ubiquitous Computing? The physical limits imposed by our bodies on the accessibility that we have to information are broken to an impressive degree. The spatial and temporal constraints that regulate our exchanges with the everyday world are deeply altered. To be sure, many important constraints still remain, but we no longer view them as set in concrete but rather as something that, through Ubiquitous Computing in combination with other technologies, can be subverted." [p. 233-234] "When a book, a person, or any other 'thing' has attached to it a visible or invisible tag which, in conjunction with a ubiquitous surveillance mechanism constitutes what we may figuratively call an 'electronic leash' the thing has lost some of its otherness. Although in many senses it remains an other, it has lost a fundamental property, namely the possibility of becoming lost. If due to a malfunctioning of the surveillance mechanism the thing eventually becomes lost, this would only have the character of an anomaly. Normally, the thing is always under surveillance. But things would partially lose their otherness in a more fundamental way. When the surveillance mechanism fades into the background and we are no longer able to experience it, things in general [...] would have been transformed becoming for us surveillable things, whether we effectively subject them to surveillance or not. A fundamental category that governs our dealings with the world would have been deeply altered." [p. 234] "By this weaving of extensions of ourselves into the surroundings, significant parts of the environment lose important aspects of their otherness and the environment as a whole tends to become more and more a subservient 'artifact'. This artifact, which the world immediately surrounding us becomes, is almost entirely 'us' rather than 'other'. In this sense, the surrounding world has almost disappeared. Portable environments carry these tendencies even further. In the extreme, the ultradisseminability of information enabled by Ubiquitous Computing would make possible to port information environments to any place, ant any time, from office to office, car, home, airport, airplane, in a seamless way. How would this affect what a 'place' is for us? The portability of the information associated with a place would tend to erase the differences between places, contributing to the uniformity of the environments in which we live. And it is precisely the differences that exist in our surrounding environments that make it alive for us the otherness of the world." [p. 234] "...we propose a first characterization of Ubiquitous Computing [...] as an attempt at obliterating the otherness of certain aspects of the world by pervasive penetration of everyday life with computing technology." [p. 235] And then they add another extension: "...an attempt at obliterating the otherness of certain aspects of the world in such a way that we are no longer aware of the obliteration. This would mean, for instance, that in their everyday life interactions - increasingly mediated by ubiquitous computing - humans would tend to become unaware of the difference between a Digital Surrogate and that which it represents." [p. 235] According to Araya ubiquitous computing doesn't really bring anything new, it just will make everything easier and more efficient. The complexity of the technologies underlying ubiquitous computing are so huge, however, that we may question the investment we're making here. Ubiquitous computing, Araya concludes, it a typical example of technology push - because it is technologically possible, we should go through with it, regardless of the fact that it doesn't even bring that many great new things. Araya says: "Ubiquitous computing has little to do with human needs and much more with the unfolding of technology per se." [p. 236] Araya states that the assumptions underlying ubiquitous computing are never questioned and this is a serious matter - according to him it will lead to "an emerging form of technological absolutism".
