Evaluation of multi-family housing systems in Poland

On the basis of selected statistical data, the authors briefly discuss the housing construction situation in Poland, focusing on two periods – that preceding the transition to a market economy (up to the end of 1988) and the period 1989–1994). Comparative analysis of selected systems of multi-family housing, based on specific criteria, has been presented. The analysis comprises systems which have been used for many years and continue to be used. The entropy method, one of the multi-criteria optimization methods, has been used in the analysis.
