Innovative Division of Information Systems of Building Enterprises According to the Methods of Economy and Process Technology/Konzeption zur neugliederung der baubetrieblichen informationssysteme nach betriebswirtschaftlichen und verfahrenstechnischen met

At the present time the implementation of building projects is impossible without using information technology. This process can be divided into 4 stages: 1) planning and constructing, 2) getting permissions, 3) building preparations, and 4) building peformance. Roughly speaking, decomposition of building activities includes two main spheres: technical and economic. Building enterprise information systems are open dynamic systems. They consist of active elements connected by material supply quantities. They also include elements showing their relations to the environment and to the client. When arranging this system, one must have in mind that the implementation of a building order should follow contract agreements with the aim of getting profit. Therefore all the deviations from guiding quantities should be avoided by compensating them. A developed building enterprise information system implies this regulating property. In this case, it is referred as cybernetic system. Contrary to the building site information systems oriented to the present time, the novelty of the new decomposition consists in that it does not deal with a pure control system and a model possessing partial systems, but with a building enterprise information system developed following modern methods of building enterprise as well as economic sciences and intended for achieving completeness and transparency. It ensures a reliable information pertaining to an important building process and permits to make timely decisions.
