Spatial models in computer-based information systems

From a series of initial studies in the area of computer cartography a dual data structure was evolved based on matrix representation of graphs and the use of boolean expressions. This data structure was used principally to represent zones in space though, by using boundaries of zones, it was possible to create line networks. The original idea was to use the boolean expressions as an input language for creating volume and area descriptions and to use the graph matrices for internal manipulation and creating graphic output. However, a way was found to interpret the boolean expression directly into the form of graphic output suitable for the raster scan displays given by television monitors. The software implementation of this process was very slow but, with the current developments in integrated circuitry, it suggested a way of creating a new form of parallel display processor. This possibility was investigated initially as a general processor to carry out several related spatial operations and then, finally, merely to create displays. The applications depend on (t) the general nature of the data structure used and the possible graphic languages it makes possible and (2) the real time manipulation of displays. In the case of three-dimensional scenes, this includes an automatic hidden line and hidden area removal capability. The particular applications which have been considered include the fast access and display of maps and technical drawings from planning, archi¬ tectural and engineering data bases; the real time generation of displays for training simulation; the preparation of animated films for teaching and entertainment; the control of numerically-controlled machine tools; and solving the placement problem in computer-aided design work and overlap problems in type setting and map annotation

Proceedings of The Multi-Agent Logics, Languages, and Organisations Federated Workshops (MALLOW 2010)

http://ceur-ws.org/Vol-627/allproceedings.pdfInternational audienceMALLOW-2010 is a third edition of a series initiated in 2007 in Durham, and pursued in 2009 in Turin. The objective, as initially stated, is to "provide a venue where: the cost of participation was minimum; participants were able to attend various workshops, so fostering collaboration and cross-fertilization; there was a friendly atmosphere and plenty of time for networking, by maximizing the time participants spent together"

A systems approach to the development of large Geographic Information Systems

Includes bibliography.Large computer-based information systems seldom achieve unqualified success. The major problem is organisational rather than technical, hence to achieve greater success in system implementation greater emphasis must be given to organisational issues than to technology. Current practise, however, tends to focus on technical issues. The aim of this research was to investigate whether a systems-based approach would lead to better understanding of the system development process, and hence form the basis of a methodology which would lead to greater success in computer-based information system implementation. The thesis comprises four parts. In the first part (Chapters 1 - 5) the literature on systems theory in sociology with particular reference to business organisations is reviewed. This review focuses on the historical development of systems thinking, particularly in business management. Beer's Viable System Model, Checkland' s Soft Systems Methodology, and Hoebeke' s ideas on the adoption of new technology provided the main ideas for developing a conceptual model for the information system development process. In the second part (Chapters 6-9) this model is applied to the information system development process to identify the strengths and weaknesses of current methods. Each stage of system development from planning to implementation is considered from a systems perspective. This involves identifying the key stakeholders, and understanding their role in the development process. In the next part three case studies are examined in the light of the theoretical material. The impact of inter-cultural communication is highlighted in these studies as the developers and customers were from· several different cultures. The author was personally involved as project manager and chief consultant in the development of two of the systems described. He was also fully aware of the progress of the other case because that development was being undertaken in the same office. Regular exchanges of views on the progress of each project took place. In the final chapter the conclusions are presented. The main conclusion is that information system implementation must be undertaken within the overall context of the organisation, must be closely aligned with the organisational business processes, and must address the conflicting needs of the different stakeholders. Effective Communication between system developers and system users is crucial to success. A focussed effort is required to achieve effective communication in a multi-cultural environment
