ABSTRACT
In the design process for buildings a number of uncertainties prevail. Nevertheless designer has to determine the design values in some optimal sense to construct the buildings. In this paper an optimal design concept for the design of building portfolios is discussed. In our concept focus is directed to three components in risk management, namely the decision situation, the objects, and objective of the risk management. Special attention is given to the assessment of the probability of favorable or unfavorable events for a considered building portfolio. The results achieved using the suggested concept is compared with the classical approach of expected total cost minimization through an illustrative example. Finally the suggested approach is tested on one numerical example.
