GENERAL MODEL OF ACCIDENT RATE GROWTH IN THE CONSTRUCTION INDUSTRY

The accident level in sectors of the national economy is estimated from such data as: the number of persons employed in the analysed sector, the number of victims of accidents at work and the frequency and seriousness of the accidents. The data have a static character: they inform about the accident level in the analysed period but not about its variation over time. Also the pace of work contributes to accidents at work. The accident level and the production volume change over years. It is essential to be able to determine the rate of variation of two quantities. For this purpose a model enabling the assessment of dynamic changes in the investigated phenomena has been developed. Besides accident indices the model takes into account indices which measure the economic effects of construction production.

An it model of a knowledge map which supports management in small and medium-sized companies using selected polish construction enterprises as an example

AbstractKnowledge is one of the most important resources of an enterprise. Skillful knowledge management can bring significant benefits including labour productivity growth, an increase in quality of provided services and also a strengthening of the competitive position of an enterprise. This paper presents an iT model of a knowledge Map which supports knowledge management in a construction enterprise. The model was developed on the basis of the results of surveys and analyses carried out in small and medium sized construction enterprises in Poland. The process approach in management was included in the proposed model and it involves analysis of an enterprise activity as a set of processes. The model contains processes occurring at enterprise level and also in the widely considered investment process in the construction industry. This assumption made the proposed knowledge Map universal and able to be applied in construc- tion enterprises operating in both the design and executive field.

Matematyczny model rozwoju sytuacji wypadkowej w budownictwie

Abstract Accidents at work constitute a heavy psychological and economic burden for companies and societies. The vast majority of cases can be prevented by appropriate and effective preventive measures. Knowledge about the course of events, their causes and consequences is required in order to carry out such actions. The knowledge gained can provide a basis for drawing conclusions of a preventive nature. The article presents a mathematical model, which was used in the study of the phenomenon of accidents in the construction industry, and provides the test results that were obtained using 350 sample cases.

Knowledge assets about construction enterprise collected in the Knowledge Map

A good level of knowledge is required in order to carry out construction processes in the correct way. The knowledge is acquired from publications, documents, legal regulations, standards, but mainly from construction projects carried out. This knowledge also resides in the employees’ minds. The recording, storing and processing of knowledge for the purpose of drawing inferences about future projects may aid management processes to a considerable degree. The “Knowledge Map” can be used as a tool supporting decision making on the basis of the accumulated knowledge. The paper presents benefits which stem from the use of the proposed Knowledge Map in a building enterprise.
