Conflict Probe Concepts Analysis in Support of Free Flight

This study develops an operational concept and requirements for en route Free Flight using a simulation of the Cleveland Air Route Traffic Control Center, and develops requirements for an automated conflict probe for use in the Air Traffic Control (ATC) Centers. In this paper, we present the results of simulation studies and summarize implementation concepts and infrastructure requirements to transition from the current air traffic control system to mature Free Right. The transition path to Free Flight envisioned in this paper assumes an orderly development of communications, navigation, and surveillance (CNS) technologies based on results from our simulation studies. The main purpose of this study is to provide an overall context and methodology for evaluating airborne and ground-based requirements for cooperative development of the future ATC system

The emergence of sociotechnical computer integrated manufacturing at a large corporation: a case study

The continued assimilation of advanced computing and information technologies in the workplace in the midst of rapidly changing socioeconomic conditions has led many corporations to transform their corporate culture and structure. These profound changes are implicating corporate functions such as planning, design, manufacturing, and marketing. A significant form of corporate re-structuring has been in the computer and information technology mediated integration of these functions which is sometimes labeled Computer Integrated Manufacturing (CIM). Fundamental questions are provoked regarding the reshaping of these emerging modes and relations of production. Do these developments represent a departure from traditional Taylorist or Fordist workplace operations and organization? Are these emerging modes of work which generally are interwoven with Japanese inspired quality improvement programs and associated manufacturing methods producing a more human-centered workplace? Do these shifts in corporate re-structuring support the possible unfolding of forms of human-centered workplace democracy? To critically inquire and address the above questions, a case study was conducted involving a large manufacturing firm which has been undergoing a radical re-structuring of all its corporate operations. The case study method involves an analysis of the internal discourse(s) and practice(s) of an emerging manufacturing facility called the Factory of the Future (FOF) in the context of a changing corporate culture mediated by computer and information technologies and changing organizational practices. Many sources of information were appropriated to construct a collage of textual material in order to present FOF's unique genealogy and to provide a detailed description of the emerging phenomenon of CIM. Among these were internal documents, videos, and interviews conducted with factory and office workers. Based on a critical interpretation of the case study findings a number of provisional conclusions were reached and may be summarized as follows: • Certain neo-Taylorist and neo-Fordist modes of production are emerging both in the factory and office as the transformation of the corporation proceeds toward a CIM mode of operation. • More human-centered organizational practices have marked the changing corporate culture although they are at times subject to conflicts and contradictions. • Managerial power has grown in the midst of computer and information mediated systems, even though worker participation and involvement in work related decisions has also been enhanced.Graduate and Postdoctoral StudiesGraduat
