Abstract

Purpose

Because of the multiple design elements and complicated relationship among design elements of complex products design, it is tough for designers to systematically and dynamically express and manage the complex products design process.

Design/methodology/approach

To solve these problems, a supernetwork model of complex products design is constructed and analyzed in this paper. First, the design elements (customer demands, design agents, product structures, design tasks and design resources) are identified and analyzed, then the sub-network of design elements are built. Based on this, a supernetwork model of complex products design is constructed with the analysis of the relationship among sub-networks. Second, some typical and physical characteristics (robustness, vulnerability, degree and betweenness) of the supernetwork were calculated to analyze the performance of supernetwork and the features of complex product design process.

Findings

The design process of a wind turbine is studied as a case to illustrate the approach in this paper. The supernetwork can provide more information about collaborative design process of wind turbine than traditional models. Moreover, it can help managers and designers to manage the collaborative design process and improve collaborative design efficiency of wind turbine.

Originality/value

The authors find a new method (complex network or supernetwork) to describe and analyze complex mechanical product design.

Design/methodology/approach

Provides an overview of nine presentations as well as internet links (or bibliographic citations) of pertinent research, on each topic covered, for further understanding of the subject matter.

Findings

There is plenty of research on which to report.

Originality/value

The paper provides information on the latest research on: current technological advances relating to connectivity to the internet; key questions relating to the voluminous amount of data generated annually; and, how computational science, and its enabling cyberinfrastructure, is tackling some of the “grand challenges” facing science and society today.

Abstract

Many Internet researchers state that computer networks provide an egalitarian forum where users are not labeled by gender, race, age, national origin or disability. This assertion ignores the experiences of many women using electronic communication systems. Focusses on several legal issues of special relevance to women, including pornography and hate speech, stalking and sexual harassment, and exclusionary practices. Suggests that the conceptual models used in this research and Internet work may help to determine future legal practices.

Abstract

When the initial library networks were established in the United States, they provided affordable, online automation services that were available from virtually no other source. The surge of automation experienced by American libraries for the past two decades has altered the historical relationships that characterize library cooperation. Local networks are being created and machine‐readable products previously available only from the networks are now being packaged on optical media and distributed to individual institutions. With these technological advances, the need for, services offered by, and financial viability of the networks have begun to undergo dramatic change. This is also a time of great opportunity for libraries and networks. There is on the horizon what may be the infrastructure for a national information network. The realization of this network will require close cooperation of librarians, who have embraced the Open Systems Interconnection (OSI) Reference Model for networking, and members of the academic and research community, which is still relying heavily on the Transmission Control Protocol/Internet Protocols (TCP/IP) for communications purposes.

Abstract

In The Information Society (Oct.‐Dec. 1995), three authors presented arguments on the future of electronic journals (e‐journals) which raised key questions that should be considered in trying to project into the future. Perhaps in the four year run‐up to the millennium there will no be dramatic change in the world of scholarly publishing. However, the three papers together pose interesting ideas for speculation.

Abstract

Despite the rapid growth of the World Wide Web in the last several years few studies have appeared in the literature assessing Web sites’ efficacy. This paper provides an original Web Assessment Index, focused on four categories: accessibility, speed, navigability and content. The scoring mechanism is explained and the index is applied to assess the Web sites of all Spanish universities. Finally, conclusions and implications derived from this study are presented.

Abstract

Purpose

Resilience concepts in integrated urban transport refer to the performance of dealing with external shock and the ability to continue to provide transportation services of all modes. A robust transportation resilience is a goal in pursuing transportation sustainability. Under this specified context, while before the perturbations, robustness refers to the degree of the system’s capability of functioning according to its design specifications on integrated modes and routes, redundancy is the degree of duplication of traffic routes and alternative modes to maintain persistency of service in case of perturbations. While after the perturbations, resourcefulness refers to the capacity to identify operational problems in the system, prioritize interventions and mobilize necessary material/ human resources to recover all the routes and modes, rapidity is the speed of complete recovery of all modes and traffic routes in the urban area. These “4R” are the most critical components of urban integrated resilience.

Design/methodology/approach

The trends of transportation resilience's connotation, metrics and strategies are summarized from the literature. A framework is introduced on both qualitative characteristics and quantitative metrics of transportation resilience. Using both model-based and mode-free methodologies that measure resilience in attributes, topology and system performance provides a benchmark for evaluating the mechanism of resilience changes during the perturbation. Correspondingly, different pre-perturbation and post-perturbation strategies for enhancing resilience under multi-mode scenarios are reviewed and summarized.

Findings

Cyber-physic transportation system (CPS) is a more targeted solution to resilience issues in transportation. A well-designed CPS can be applied to improve transport resilience facing different perturbations. The CPS ensures the independence and integrity of every child element within each functional zone while reacting rapidly.

Originality/value

This paper provides a more comprehensive understanding of transportation resilience in terms of integrated urban transport. The fundamental characteristics and strategies for resilience are summarized and elaborated. As little research has shed light on the resilience concepts in integrated urban transport, the findings from this paper point out the development trend of a resilient transportation system for digital and data-driven management.
