Resumen de Models de priorització d'inversions utilitzant criteris de desenvolupament sostenible
This Doctoral Thesis addresses aspects of interest for hydraulic infrastructure managers, such as investment decision support tools, in order to provide both decision support and the justification tools which are required by the entities regulating the service of future investments.
The aim is to develop a new methodology for the prioritization of investments that allows an objective, transparent and participatory distribution using the Sustainable Development criteria. To implement the methodology, two models have been nurtured: the Distribution Network Renewal Model (an ordering model) and the Investment Prioritization by Entries Model (a distribution model for the total volume of investment).
First, a methodology for prioritizing distribution network investments using sustainable development criteria is developed: the Distribution Network Renewal Model, using sustainable development criteria. The management model aims to materialize the methodology of prioritizing the actions from a list of inventoried assets.
Second, a methodology for the distribution of investment with sustainable development criteria is developed: the Prioritization Model for Matching Investments. The distribution model aims to distribute the volume of investment between the different items and sub-headings that make up the investment plan of the company. In this case, due to the heterogeneous nature of the investment plan, a methodology has been developed consisting of three phases. A first phase where the investment volume is determined by legal factors, a second one where the remaining investment is distributed between entries, and a last phase where the outlay on each entry is distributed among those sub-items of investment that make up each of the entries.
Finally, a sensitivity analysis was performed on both methodologies to check the robustness of the developed models and its sensitivity to the diverse contributions of each group. The Distribution Network Renewal Model has been verified in Aigües de Barcelona network after a first year of execution of investments in the renewal of the distribution network by implementing the prioritization of the Model.
