    It is more important than ever for printers to improve efficiency and productivity, and the means for doing so are available. Computer-assisted scheduling is one method that is claimed to increase throughput speed and reduce costs, among other benefits. Recently, scheduling applications have started to increase in popularity, and many management information systems (MISs) have built-in scheduling features. However, only 15% of the companies that own scheduling software utilize it. The first part of this research project seeks to determine the reasons for the low usage. Another way to increase efficiency is through Lean manufacturing, a strategy for eliminating non-value-added activities, such as defects, excess inventory, and overproduction. Lean manufacturing and computer-assisted scheduling share many of the same objectives. The second part of the research project seeks to determine whether or not there is a difference in production performance between users and nonusers of scheduling software from a lean manufacturing perspective. The analysis is based on data collected through an email questionnaire from 60 commercial printing companies in the U.S. It was found that the surveyed companies who own scheduling software but do not use it, do not rely on the application’s capability because they believe that they can achieve better control with manual scheduling. Furthermore, they believe scheduling software is difficult to integrate with their workflow. Companies who have owned an MIS for 5 years or fewer have a more negative perception about scheduling software compared with those who have owned one for a longer time. In the research, it was also found that companies using scheduling software have higher utilization rates of equipment, shorter lead times for paper storage, and a higher percentage of short makereadies out of the total number of makreadies. Nonusers of scheduling software have shorter throughput time and shorter waiting time for a job between preflighting and platemaking, between platemaking and plate mounting, and between completed printing and the first postpress operation. In general, the scheduling software users in the study are more homogeneous as a group in performance, whereas the nonusers are more diverse in performance, with a relatively high percentage performing at a very low or very high level. The implication of the study is that scheduling software needs to be more userfriendly and easier to customize to increase the flexibility and capability of integrating it into a workflow. Furthermore, companies that own scheduling software, but do not use it, should investigate the possibility of achieving better performance by beginning to use the scheduling application. Scheduling software that is already in house has the capability of enhancing a lean manufacturing effort

    Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management; and, (S.M.)--Massachusetts Institute of Technology, Engineering Systems Division; in conjunction with the Leaders for Global Operations Program at MIT, 2009.Cataloged from PDF version of thesis.Includes bibliographical references (p. 74-77).Virtual Business System (VBS) is a system with software and hardware components designed by Raytheon employees to improve operational performance by facilitating and reinforcing lean behavior. It has helped contribute to four years in a row of twenty-percent yearly reductions in costs by providing near real-time metrics information, visibility into the details underlying those metrics, and publishing results to provide accountability for continuous improvement efforts. Originally designed for use in a manufacturing cell, its use has since expanded to include project management, engineering, quality, and other functions. This thesis examines how VBS has contributed to internal alignment at Raytheon and explores whether it can fulfill Raytheon's external supply chain coordination needs as well. VBS was successfully upgraded to allow supplier access over Citrix; the next step is to conduct a pilot implementation to test the system in practice. As a "homegrown" system, VBS can be made to do nearly anything, and in time could fulfill Raytheon's supply chain integration needs. In the near term, additional work is likely to be necessary in the areas of data access control, user interface, and extension from stand-alone system to a peer-to-peer information sharing network. The VBS team will also need to continue gathering executive sponsorship and support in order to motivate the necessary change in business processes. A number of lessons applicable to supply chain integration systems in general can be learned from the success of VBS.(cont.) These include: the importance of ensuring client control and security of the data; the potential gains made possible by sharing functionality in addition to data; the need to include information about improvement processes when sharing information; and the critical need that the application remain flexible and responsive to change in user needs.by Akiva Holzer.S.M.M.B.A

    Hierarchical categorisation of tags for delicious

    In the scenario of social bookmarking, a user browsing the Web bookmarks web pages and assigns free-text labels (i.e., tags) to them according to their personal preferences. In this technical report, we approach one of the practical aspects when it comes to represent users' interests from their tagging activity, namely the categorization of tags into high-level categories of interest. The reason is that the representation of user profiles on the basis of the myriad of tags available on the Web is certainly unfeasible from various practical perspectives; mainly concerning the unavailability of data to reliably, accurately measure interests across such fine-grained categorisation, and, should the data be available, its overwhelming computational intractability. Motivated by this, our study presents the results of a categorization process whereby a collection of tags posted at Delicious #http://delicious.com# are classified into 200 subcategories of interest.Preprin

    The Impact of Industry 4.0 on Supply Chain Capability and Supply Chain Resilience: A Dynamic Resource-Based View

    Get PDF
    Industry 4.0, a collection of emerging intelligent and digital technologies, has been the main interest of both researchers and practitioners in operations management (OM) in recent years. Despite its proclaimed effectiveness in supply chain (SC) management, empirical studies examining the effects of Industry 4.0 adoption on SC resilience have been underrepresented in the current OM literature. In our study, we explore the effects of 16 Industry 4.0 technologies and IT advancement concerning SC resilience through the mediating roles of SC capabilities with respect to SC collaboration and SC visibility. Following the dynamic resource-based view (RBV), we regard Industry 4.0 adoption and IT advancement as two important IT resources with heterogeneity, SC collaboration and SC visibility as essential SC dynamic capabilities, and SC resilience as competitive advantages. We suggest the combination and evolution of IT resources and dynamic SC capabilities helps firms obtain the competitive advantage regarding SC resilience. Using data from a survey of 408 Chinese manufacturing firms, we reveal Industry 4.0 adoption is positively related to IT advancement and that Industry 4.0 has a nonsignificant impact on SC capabilities, whereas IT advancement has a positive impact on SC capabilities. Additionally, both SC collaboration and visibility positively influence SC resilience and significantly mediate the impacts of Industry 4.0 and IT advancement on SC resilience. Our study offers an enhanced understanding of the specific flows between Industry 4.0 and SC resilience and provides nuanced insights for both literature and practice

    E-Business systems naturally have greater security risks than traditional business systems, therefore it is important for e-business systems to be fully protected against these risks. Customers, suppliers, employees, and numerous other people use any particular e-business system daily and expect their confidential information to stay secure. Hackers are one of the great threats to the security of e-businesses. Some common security concerns for e-Businesses include keeping business and customer information private and confidential, authenticity of data, and data integrity. Some of the methods of protecting e-business security and keeping information secure include physical security measures as well as data storage, data transmission, anti-virus software, firewalls, and encryption to list a few.Розглянуто та рекомендовано до друку на засіданні кафедри інноваційного менеджменту та підприємництва, протокол No1 від 27 серпня 2015 року.

    In the scenario of social bookmarking, a user browsing the Web bookmarks web pages and assigns free-text labels (i.e., tags) to them according to their personal preferences. The benefits of social tagging are clear – tags enhance Web content browsing and search. However, since these tags may be publicly available to any Internet user, a privacy attacker may collect this information and extract an accurate snapshot of users’ interests or user profiles, containing sensitive information, such as health-related information, political preferences, salary or religion. In order to hinder attackers in their efforts to profile users, this report focuses on the practical aspects of capturing user interests from their tagging activity. More accurately, we study how to categorise a collection of tags posted by users in one of the most popular bookmarking services, Delicious (http://delicious.com).Preprin
