Vertical Integration and Dis-integration of Computer Firms: A History Friendly Model of the Co-evolution of the Computer and Semiconductor Industries
In this paper we present a history-friendly model of the changing vertical scope of computer firms during the evolution of the computer and semiconductor industries. The model is "history friendly", in that it attempts at replicating some basic, stylized qualitative features of the evolution of vertical integration on the basis of the causal mechanisms and processes which we believe can explain the history. The specific question addressed in the model is set in the context of dynamic and uncertain technological and market environments, characterized by periods of technological revolutions punctuating periods of relative technological stability and smooth technical progress. The model illustrates how the patterns of vertical integration and specialization in the computer industry change as a function of the evolving levels and distribution of firms' capabilities over time and how they depend on the co-evolution of the upstream and downstream sectors. Specific conditions in each of these markets - the size of the external market, the magnitude of the technological discontinuities, the lock-in effects in demand - exert critical effects and feedbacks on market structure and on the vertical scope of firms as time goes by
Automated CPX support system preliminary design phase
The development of the Distributed Command and Control System (DCCS) is discussed. The development of an automated C2 system stimulated the development of an automated command post exercise (CPX) support system to provide a more realistic stimulus to DCCS than could be achieved with the existing manual system. An automated CPX system to support corps-level exercise was designed. The effort comprised four tasks: (1) collecting and documenting user requirements; (2) developing a preliminary system design; (3) defining a program plan; and (4) evaluating the suitability of the TRASANA FOURCE computer model
Gas-Grain Simulation Facility: Fundamental studies of particle formation and interactions. Volume 2: Abstracts, candidate experiments and feasibility study
An overview of the Gas-Grain Simulation Facility (GGSF) project and its current status is provided. The proceedings of the Gas-Grain Simulation Facility Experiments Workshop are recorded. The goal of the workshop was to define experiments for the GGSF--a small particle microgravity research facility. The workshop addressed the opportunity for performing, in Earth orbit, a wide variety of experiments that involve single small particles (grains) or clouds of particles. Twenty experiments from the fields of exobiology, planetary science, astrophysics, atmospheric science, biology, physics, and chemistry were described at the workshop and are outlined in Volume 2. Each experiment description included specific scientific objectives, an outline of the experimental procedure, and the anticipated GGSF performance requirements. Since these experiments represent the types of studies that will ultimately be proposed for the facility, they will be used to define the general science requirements of the GGSF. Also included in the second volume is a physics feasibility study and abstracts of example Gas-Grain Simulation Facility experiments and related experiments in progress
Software development tools: A bibliography, appendix C.
A bibliography containing approximately 200 citations on tools which help software developers perform some development task (such as text manipulation, testing, etc.), and which would not necessarily be found as part of a computing facility is given. The bibliography comes from a relatively random sampling of the literature and is not complete. But it is indicative of the nature and range of tools currently being prepared or currently available
Multi-community command and control systems in law enforcement: An introductory planning guide
A set of planning guidelines for multi-community command and control systems in law enforcement is presented. Essential characteristics and applications of these systems are outlined. Requirements analysis, system concept design, implementation planning, and performance and cost modeling are described and demonstrated with numerous examples. Program management techniques and joint powers agreements for multicommunity programs are discussed in detail. A description of a typical multi-community computer-aided dispatch system is appended

Effective applications of microcomputer-based management information and decision support systems for small and medium sized enterprises
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Firstly, this thesis reviews the literature on the application of microcomputer-based Management Information Systems (MISs) and Decision Support Systems (DSS) to Small and Medium sized Enterprises (SMEs). It is found that the hardware platform today is already sufficient for SMEs. However, information regarding successful implementation of MISs for SMEs is scarce and largely fragmented.
DSS requires more focused and dedicated use of information to support managerial decision making. Unfortunately, the development of DSSs for SMEs is even more backward. Yet, there is an emerging need for SMEs today because business operations have become more sophisticated under intensified
competition.
With this scenario in mind, the author undertook intensive questionnaire and case surveys to find out the current development and trends for the effective applications of MISs and DSSs. In 1987, the author was awarded the Oshikawa Fellowship by Asian Productivity Organisation in Tokyo and started the present research. 446 completed questionnaire survey sheets from U.K. and Hang Kong have been received and analysed. 67 SMEs and related organisations in 6 developing/developed countries were also visited. This forms the knowledge for the development of expert systems (ES) for effective applications of MIS.
The approach for DSS is based on a carefully selected business game which has most of the common business decision parameters. Intensive experiment with over 100 subjects was conducted in running the game, with an average time contribution of about 20 hours/person. The findings are again consolidated and structured into an ES.
Longitudinal research was conducted in 5 representative SMEs. With the use of action learning and participation of the researcher, more in-depth firsthand information were obtained and analysed. These form part of the input to the ES as well.
Both ES have been validated and further improved. The experimenters find these as keys to develop MIS/DSS for SMEs. A marketing plan is suggested to launch these two products so that they can become more easily available. Finally, recommendations are made on the effective use of the ES and for further development
Continued study of NAVSTAR/GPS for general aviation
A conceptual approach for examining the full potential of Global Positioning Systems (GPS) for the general aviation community is presented. Aspects of an experimental program to demonstrate these concepts are discussed. The report concludes with the observation that the true potential of GPS can only be exploited by utilization in concert with a data link. The capability afforded by the combination of position location and reporting stimulates the concept of GPS providing the auxiliary functions of collision avoidance, and approach and landing guidance. A series of general recommendations for future NASA and civil community efforts in order to continue to support GPS for general aviation are included
