A meaningful contribution to the evaluation of heterogeneous public investments is described in this paper. The proposed methodology provides a step towards sustainable urban planning in which decisions are taken according to clear, consistent and transparent criteria assisted by the MIVES multi-criteria analysis framework. The MIVES methodology combines Multi-criteria Decision Making (MCDM) and Multi-Attribute Utility Theory (MAUT), incorporating the value function (VF) concept and assigning weights through the Analytic Hierarchy Process (AHP). First, a homogenization coefficient is calculated to develop the Prioritization Index for Heterogeneous Urban Investments (PIHUI), so that non-homogenous alternatives may be comparable. This coefficient measures the need of society to invest in each public project through the consideration of its contribution to the regional balance, the scope of its investment, the evaluation of the current situation and the values of the city. Then, the MIVES multi-criteria framework is used to evaluate the degree to which each investment would contribute to sustainable development. Different economic, environmental and social aspects were considered through a decision framework, constructed with the 3 aforementioned requirements, 5 criteria and 8 indicators. The case study conducted for the Ecology, Urban Planning and Mobility Area of Barcelona municipal council is presented in this paper, showing how this method performs accurate, consistent, and repeatable evaluations.
