By analyzing the individual stages of the building's life cycle, it can be easily concluded that the building's exploitation process is the longest and at the same time it is the justification for the construction project related to the construction of this building. In the course of the building's exploitation, various phenomena occur that affect...

Difficult and complex geological conditions are often an obstacle to the efficient implementation of construction works related to the erection of objects, in particular, earthworks and foundations. In the event of an additional occurrence of adverse weather conditions, there may be a delay in the final effect of the work and exceeding the construc...

The problem related to the technical wear of the building affecting the state of the structure is crucial from the end user perspective. It influences the maintenance phase in the lifecycle of the object. Researchers agree that knowledge about factors influencing the technical state of the construction is important in terms of cost estimation of wo...

The article presents the problem of the analysis of post-inspection protocols of buildings in order to obtain the necessary data and information for the construction of a system supporting the technical management of residential buildings. The attention was primarily focused on the document itself - a protocol of control and automated technique of...

The study presents a model for the evaluation of construction projects from the point of view of the client (e.g. developer company). The problem lies in choosing the best solution from the point of view of many criteria. The proposed model is based on a multi-criteria comparative analysis using fuzzy logic. The first part of the paper presents a s...

The mining methods are classified as the methods of data analysis and the knowledge acquisition and they are derived from the methods of “Knowledge Discovery”. Within the scope of these methods, there are two main variants associated with a form of data, i.e.: “data” and “text mining”. The author of the paper tries to find an answer to a question a...

In the large-scale facilities, including on-site storage or shopping malls, floor plays an important role. It has to meet special requirements regarding mechanical properties, aesthetics and durability. Despite much effort, both in the design and execution phase, cases of damage of the floor happens, causing some specific consequences – often assoc...

The subject of the article is to present the possibility of applying artificial neural network in analysis of observational data on the issue of simulation concrete supplies in construction industry. Neural networks allows a quick and efficient way to model phenomena at different levels of complexity. They can be used both in processes of well and...

The article discusses the problem of technical management of large warehousing facilities from the aspect of construction of a decision-making supporting system or, strictly speaking, acquisition of the necessary knowledge as a resource of such a system. The article presents the standard procedures that are in force in Poland concerning technical m...

Building management is performed during the phase which follows the building phase of a building's life cycle – the operational phase. This phase involves several management activities among which the most important consist in technical maintenance of a building. The abandonment of these activities may limit the functionality of a building and, in...

The article presents the problem of knowledge in knowledge-based systems, such as advisory systems used in construction engineering. The unique characteristics of construction engineering translate directly into unique characteristics of knowledge resources, which is evident in the potential sources of knowledge. Many of them are not open, uncertai...

Streszczenie: Inwestorzy coraz częściej dostrzegają konieczność oceny kosztów przedsięwzięcia z uwzględnieniem fazy eksploatacji obiektu, a także jego likwidacji. Skłaniają się ku poniesieniu większych kosztów początkowych na rzecz zmniejszenia przyszłych wydatków wiązanych z opłatami, utrzymaniem, remontami i utylizacją. Dokonanie optymalnego wybo...

The paper presents the evolution of concepts, an overview of research and applications pertaining to reliability in construction production, the use of reserves, robust itineraries, and contingency of time and cost. It describes areas of management advisory systems in relation to the cycle of risk analysis. The article also presents the main trends...

An advisory system for repairs of industrial concrete floors is a supporting tool for making material and technological decisions in the sphere of problems of recurrent character. The presented advisory system has the character of a hybrid system. Various elements of tools from the artificial intelligence group have been used in it. Artificial neur...

This article presents the possibilities of using mining techniques in building Decision Support Systems. One of the biggest problems is the issue of gaining data and knowledge, their mutual representation and reciprocal usage. Data and knowledge make up the resources of the system and are its key link. It has been estimated that 70% to 80% of the s...

The complexity and multi-aspect nature of problems supports the search of various and more complex methods of data analysis. This paper is focused on a description of diverse methods and tools as well as on showing their possibilities. The quality of results is very crucial in decision-making process. The project selection problem was used as the b...

In the article the autor presents the problem of choice of the concrete construction repair systems. As far as the material choice is concerned, fuzzy logic was used. The article's idea was to show the possibilities of the fuzzy logic, especially the possibilities of changing qualitative into quantitative data.

It is very often the case that the units responsible for the maintenance of the building have to repair industrial flooring. The large number of available materials and technologies as well as some other factors, make it nec-essary to use tools which would help to make good decisions. Hybrid advisory system is a tool which supports the process of d...

Streszczenie: Zaprezentowano problem wyboru miejsca lokalizacji inwestycji – budynku mieszkalnego. Potencjalne miejsca lokalizacji zostały zawężone do miasta Poznania i najbliżej leżących miejscowości. Z analizą przypadku związane jest przedsiębiorstwo, które dotychczas działając w branży budowlanej – budownictwo przemysłowe, w sytuacji braku zlece...

This paper presents the main foundations of the structure and operation of the support system for industrial surfaces management. This model of system as a tool supporting the administrator/owner of surface enables to reach decisions essential for the proper operation of the surface considering three aspects of management: technical (referring to m...
