Abstract
This paper describes the approaches to analysis in order to optimize the construction facilities (buildings and complexes) information models management. Two criteria have been proposed and discussed for the model quality evaluation: model informational saturation criterion and model topicality criterion. Practical application of the first criterion enables to define the optimal plan of information model filling. Herewith, the optimization is carried out through the maximum volume of useful information. The criterion is used at all stages of the model life cycle during the course of the model data updating. The second criterion allows to evaluate the need in the model data update. Being a vector (in the space of the modelling object significant values) of deviation of the model data from the model object data, the criterion represents the need to initiate the model data updating procedure using the predefined rules
Highlights
Information technologies development trends in general, and information modeling tools in particular have led to the situation, when the use of information modeling tools and technologies in construction and utility complex are not an exception
Buildings and construction facilities information models are created for different stages of the life cycle and for finding various solutions [1-7]
The use of information modeling technologies for management tasks in city scale and area scale distributed and grid system imposes the requirements for elaboration of the formalized rules for data exchange and information management
Summary
Information technologies development trends in general, and information modeling tools in particular have led to the situation, when the use of information modeling tools and technologies in construction and utility complex are not an exception. Along with the wide use of these technologies [7], there is no generally accepted (both industry, and government level) rules for management of information, development, and use of information models for various stages of the buildings life cycle [7-12]. This situation leads to the use of irrational ways for creation of information models related to entering excessive data, longer time needed for models creation, puzzled structure of the model, etc
