    An Analysis of the Interaction between the J3 and J4 War Planning Staffs during the Phases of Crisis Action Planning

    Get PDF
    A principal operational concept of Joint Vision 2020 is that of Focused Logistics, which promotes a merger of information and logistics technologies. The Defense Advanced Research Projects Agency\u27s Advanced Logistics Project (ALP) supports this concept of Focused Logistics and seeks to leverage information technologies to obtain control over the logistics pipeline. The current campaign planning process is limited by the information made available to the decision-makers. In order for ALP to assist the decision-maker in selecting a single optimal deployment plan, the founding assumptions of alternatives considered must be valid. Logistical issues are major constraints in the war planning process. Often, when planners are faced with Crisis Action Planning (CAP) the interaction between the operations planners and the logistics planners is limited due to the time sensitivity of the situation. Because logistics information is a main constraint in the CAP process, operational planners build their plans based on inappropriate logistic assumptions. This thesis will explore the contribution that ALP\u27s architecture could bring to the crisis action planning process. The focus of this research is to analyze the interaction between the operational and logistical communities and determine the ideal planning tool that will enhance the communication between the two communities

    Innovative Data Management in advanced characterization: Implications for materials design

    Abstract This paper describes a novel methodology of data documentation in materials characterization, which has as starting point the creation and usage of any Data Management Plan (DMP) for scientific data in the field of materials science and engineering, followed by the development and exploitation of ontologies for the harnessing of data created through experimental techniques. The case study that is discussed here is nanoindentation, a widely used method for the experimental assessment of mechanical properties on a small scale. The new documentation structure for characterization data (CHADA) is based on the definition of (i) sample, (ii) method, (iii) raw data and (iv) data analysis as the main component of the metadata associated to any characterization experiment. In this way, the relevant information can be stored inside the metadata associated to the experiment. The same methodology can be applicable to a large number of techniques that produce big amount of raw data, while at the same time it can be invaluable tool for big data analysis and for the creation of an open innovation environment, where data can be accessed freely and efficiently. Other fundamental aspects are reviewed in the paper, including the taxonomy and curation of data, the creation of ontology and classification of characterization techniques, the harnessing of data in open innovation environments via database construction along with the retrieval of information via algorithms. The issues of harmonization and standardization of such novel approaches are also critically discussed. Finally, the possible implications for nanomaterial design and the potential industrial impact of the new approach are described and a critical outlook is given

    Thesis (S.M.in Construction Engineering and Management)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2002.Includes bibliographical references (p. 131-132).The economic essence of Internet-based B2B business has become an ever-important market concern after the dot-com mania collapsed in early 2001. Many theories have been developed to understand this new business pattern. Nevertheless, lots of puzzles remained unsolved. So far, even whether B2B e-business is a temporary phenomenon; or is it just the extension of the old VAN-EDI system is still under debate. This research tries to answer some of the most fundamental questions of why and how companies adopt e-business application by studying the e-business fast mover's behaviors in the following three domains: the initiative for firm to adopt e-business, the business model and strategy developed to leverage Internet-based network system, and the barriers to implementing e-business practice. (1) The initiative for firm to adopt B2B e-business: the improvement of economic efficiency is used to measure firm's incentive in adopting E-business. Internet-based business tends to reduce production and distribution cost; and increases market transparency. It is argued that benefits from lowered cost are offset by buyer's higher bargaining power. Nevertheless, study shows that market power is critical as advanced computation capacity improves firm's ability to detect buyer's behavior, firms with larger market power have access to better quality data and gain substantial edge over smaller competitors. (2) The business models and strategy developed by firms to leverage e-business: Strategies of existing large firms are to pay their suppliers to link to their system in order to leverage the reduced production cost. They can, however, increase revenue by improving IT-based marketing and service quality. Small firm's strategy is to link their system with large firm's interface to gain competitive advantage over rivals. Start-up's strategy has been to reinforcing network externality to gain market share as markups are thin. The new trend for start-ups will be to differentiate their functionability and create new value-added for production firms. (3) The barriers for firms to adopt e-business: In the industry level, major barriers including fragmented market structure, unstandardized product and production process. In the firm level, the major barriers including organization and culture restructuring, interoperability between ebusiness application and with legacy system, lack of qualified personnel and knowledge, and the interoperability with complementary companies.by I-Tsung Tsai.S.M.in Construction Engineering and Managemen
