Een exploratieve studie naar de financieel-economische implicaties van de invoering van een baten-lastenstelsel bij de Nederlandse Rijksoverheid voor de instandhouding van civieltechnische netwerken. Doel is om als professioneel opdrachtgever op basis van bedrijfseconomische beginselen de instandhoudingsactiviteiten optimaal te sturen. Hiermee kan een infrastructuurnetwerk effectief en efficiënt blijven voldoen aan de maatschappelijke wensen en behoeften naar vervoer en transport.

LCC analyses (LCCA) and discounting calculations are applied by public sector organizations in the Netherlands. Still numerous misunderstandings can be recognized. An overview is given of some common misunderstandings found in Life Cycle Costing Analyses. Issues relating to public assets are: the absence of residual value, long life cycles, high investment costs, long operation and maintenance expenditures and a low discount rate. All these issues make a careful estimation of life cycles and input parameters more important than most governments and local authorities realize. Six suggestions to improve LCC analyses of public assets are given.

Ports worldwide are confronted with a changing environment in terms of global economy and a rising awareness of the necessity of balancing economic, social, and environmental interests. Therefore, in recent years, a lot of research has been directed towards studying sustainable port development. However, the focus has been on greenfield ports, while little has been said about ports in transition. This paper presents a framework for sustainable development of ports in transition and applies it to the re-development of Bay of Havana in Cuba.

In many parts of the world, flooding is a big risk. There are numerous strategies to reduce flood risk. The amount of flood risk reduction strategies grows exponentially with the amount of possible measures that can be implemented and possible timings when measures can be implemented. In this paper, the use of a financial method called “equivalent annual cost” (EAC) is assessed to reduce that number of strategies and evaluate cost-optimal strategies. The use of EAC allows the comparison between short-term and long-term measures by expressing them into an annual interest weighted expected expenditure. As soon as a measure has to be implemented (i.e. the annual risk becomes too large or the safety standards are exceeded), the EAC for all combinations of measures is determined and the combination is implemented with the lowest EAC. This almost leads to cost-optimal flood risk reduction strategies that, by manual optimization, can be improved further. A case study has also been performed in the Hollandsche IJssel which proved the use of EAC. Here it has led to cost-optimal flood risk reduction strategies. The method is tested in one case and it is recommended to apply and test it in other cases as well.
