1. füzet - Szlávik Lajos: A vízkár-elhárítási védekezési feladatok országos információs rendszerének koncepciója, megvalósítása és működése

A vízkár-elhárítási védekezési feladatok... 49 — The Ministry for Transport Communication and Water Management (KHVM) and the National Water Authority (OVF). Organisation and management at national scale; — Central Organisation of Flood and Excess Water Defence and the National Hydrological Forecasting Centre of the Water Resources Research Centre VITUKI. The above listed 17 agencies carry out information exchange at multiple levels. The information system (in development and partly implemented) serves the computerized support of this information exchange. Contributing agencies can be grouped according to their level of management into regional and national ones. This grouping means that while the regional agencies perform actual defence actions the national ones mostly collect, process and integrate information. The regional level can be further subdivided into "defence sections" and the regional defence management. Defence activities of the various levels of management shall include the following tasks: — Collection, storage, processing and forwarding information; — Evaluation of the situation, analysis and decision support; — Decision making in respect to the actual defence actions; — Organisation of defence work, assuring the respective conditions; management; supervision of the work implemented; — Writing and forwarding of reports; — Preparation and distribution of information booklets; — Documentation of the work done. These typical tasks are connecting each other at various levels. The emphasis is laid on the techniques of processing and forwarding of information. One of the major problems of defence management is that (disregarding the level of management) the time available for making the decision on the action to be made is not sufficient for appropriately evaluating the situation. Thus the major task of the information system under development is to provide information support for the decision making levels. Consequently the basic objective is to increase the efficiency of defence action by improving and upgrading information handling and forwarding. In order to fulfill this task the time-lead of making decision on defence action must be shortened: more and better processed information should be more rapidly forwarded and stored in a retrievable manner, showing also interrelationships. VIR consists of six subsystems. These are: the hydrological subsystem; the inventory of the technical establishments of defence; the administrative tasks of defence; preparation of reports and information materials; inventory of resources available for defence action; preparation of defence manuals, guides. VIR has two functions: The first is the provision of services for the given level of defence-management through the local computer network. The other one is to receive and forward information from/to the management levels above and below through the respective channels of information transmission. The information system of defence against water hazards is in continuous operation. It is done in such a way that certain modules of the system are in continuous operation and depending on the hydrometeorological situation, which decisively affects the actions of defence, other modules will be launched as required. In the development of VIR a new system of computer procedures and information handling algorithms was established and it was not based on the adoption of existing information systems. The basis of the system is the group-communication software Lotus Notes. The concept and first operational elements of VIR were made in 1994, followed by continuing development. The first trial operation was made in 1994 and operational use for supporting defence management has been performed since 1995. The modules of the system can operate also independently form each other. At the present 27 modules of the planned 48 ones are in operation ( Table /.). The modules as appearing on the screen of the user are shown by Figs 1-8. The unified use of the
