Applying System Dynamics To Confront Complex Decision Making In R&D Systems#11;#11;: A Knowledge Based Approach, Arash Golnam, Nader Ale Ebrahim
Applying System Dynamics To Confront Complex Decision Making In R&D Systems#11;#11;: A Knowledge Based Approach, Arash Golnam, Nader Ale Ebrahim
Nader Ale Ebrahim
Research and development has always played a strategically important role in the survival and the growth of technology-based firms. R&D is positively linked to company performance measures such as sales, productivity and shareholder returns and in addition to this, facing increased competition, as a result of globalization the viability of many established firms is based on the efficiency of their R&D activities. Similar to other business models, R&D systems are characterized by complex structure and dynamic behavior. It's often difficult to predict or trace the consequences of certain decisions due to the existence of delays, non-linearities and causal feedback inherent …

n recent years, along with the trend toward clean air and less dependency to imported oil products, there has been increasing willing to use substitute fuels in transport industry. Automobile industry is an exhaustive industry bringing development for any country. The industrial capabilities needed for development rest in this branch of industry. The Iranian automobile making companies move in line with this aim. But in recent decades, in addition to development of automobile industry, the pollution too has occupied the minds of the authorities of these companies. Some measures, investments, researches, and exhaustive studies related to the pollution problem have …
Uml Activity Diagram Semantics And Automated Gui Prototyping, Nancy Winniford Ashley, Timothy E. Meehan, Norman Carr
Uml Activity Diagram Semantics And Automated Gui Prototyping, Nancy Winniford Ashley, Timothy E. Meehan, Norman Carr
Journal of International Technology and Information Management
Extended Activity Semantics (XAS) is a notation which can be used with Unified Modeling Language (UML) activity diagrams to specify user interactions with a system and to automatically generate a prototype of the graphical user interface (GUI) that would be used in these interactions. XAS has been incorporated in a CASE tool, Guibot, which has been developed as a plug-in for Rational Rose, a leading UML tool. The notation and tool address a specific gap in UML – the inability to model user interaction.

Internet Technology In 2010: The Issue Of Ipv6 Adoption In The U.S.A., Garry L. White, Jaymeen R. Shah, James R. Cook
Journal of International Technology and Information Management
Computer industry literature suggests that IPv4 Internet addresses are likely to have been depleted by the year 2010, and at least Asia and Europe will be using the new IPv6 Internet addresses. Literature also suggests that the U.S.A. is lagging behind Asia and Europe with the implementation of IPv6. Empirical data supporting the fact that the U.S.A. is lagging behind is not available in the literature. This paper presents the issues regarding IPv6, reasons why Asia and Europe are implementing IPv6, and why the U.S.A. is lagging behind. Empirical data is presented to support the literature’s suggestion that the U.S.A. …
Information View Of Organization, Bob Travica
Information View Of Organization, Bob Travica
Journal of International Technology and Information Management
This article proposes an information view of organization that brings the information systems field closer to organization theory. Although voluminous bodies of literature have been developed within each of these disciplines and links between them do exist, their mutual informing is still insufficient. The proposed view of organization is intended to help convey results of information systems research to organizational scholars, while broadening theoretical horizons of the former. This article discusses the premises, conceptual framework, examples, and preliminary evidence of the information view of organization.
Time Dimension For Business News In The Knowledge Warehouse, Pawel J. Kalczynski
Time Dimension For Business News In The Knowledge Warehouse, Pawel J. Kalczynski
Journal of International Technology and Information Management
This paper proposes a data structure to support the integration of business news and data in the knowledge warehouse using the Temporal Document Retrieval Model (TDRM). Temporal document retrieval takes into account the time context expressed as temporal phrases in the document content. The maintenance and scalability of the proposed data cluster is discussed. The results of temporal document retrieval experiments based on typical and ad-hoc time constraints, performed on a large corpus of business news are reported. The experiments showed that the instantaneous TDRM-based retrieval using the proposed cluster is possible with the currently available database technology and confirmed …
A Critical Time For Ultra-Wide Band, Gary F. Templeton, Mark B. Schmidt
A Critical Time For Ultra-Wide Band, Gary F. Templeton, Mark B. Schmidt
Journal of International Technology and Information Management
Ultra-wideband (UWB) is a promising class of high-speed wireless communications applications that is projected to significantly change local and wide area network architectures. This article describes the technology, its probable application areas, the environmental forces that are constraining and enabling commercialization, and the prospects for short-term growth for UWB services. Commercial sale and distribution of UWB products has been approved, and widespread sale is expected by 2007.
A Framework For Describing And Classifying Multicriteria Portfolio Selection Problems: An Object-Oriented Approach, Heinz Roland Weistroffer, Charles H. Smith
A Framework For Describing And Classifying Multicriteria Portfolio Selection Problems: An Object-Oriented Approach, Heinz Roland Weistroffer, Charles H. Smith
Journal of International Technology and Information Management
Many decisions require not a single solution alternative, but a set or portfolio of alternatives. For example, a business generally produces not a single product, but a portfolio of products, and a project is tackled not by a single individual, but by a team of individuals. Unfortunately, the portfolio selection problem has been largely neglected in the literature. Though many specific problem environments have been discussed using heuristic, ad hoc methods, no general methodology or theory has been developed. This paper proposes an object-oriented framework to provide a theoretical foundation for future research on the portfolio selection problem.
