Investment into New Technology under Uncertainty Conditions

The Republic of Croatia is undergoing a massive reconstruction of large infrastructure systems, specifically design and highway construction with accompanying service buildings. Hence the need for the foundation work for bridges, viaducts, overpasses, office and public service buildings on the soil of low stiffness, e.g. of inadequate bearing capacity. Various soil improvement technologies might enhance its bearing capacity, e.g. keep under control or reduce total and differential settlements. The paper presents methodology of the decision making on a probable purchase investment into a potential soil improvement technology on the example of a typical highway structure. Firstly, criteria are set on the basis of defined designers’ , investors’ and wider community’ s interests according to which the rank list of foundation technologies would be made up using multi-criteria analysis of AHP method. Then, using the tree method decision and applying expected values criteria the decision on investment into soil improvement technology purchase will be reached. Providing that the decision on investment has been reached, the decision on the selection of a proposed technology by means of a decision tree will be made.
