Intervals and Possibility Degree Formulae for Usage Prioritization of Cartagena Coastal Military Batteries

Abstract

Several projects have been proposed in recent years with the goal of restoring some of Cartagena’s (a Spanish city) old military batteries so that they can be turned into touristic, scientific, or cultural sites. In previous work, a combination of AHP and TOPSIS (A+T, hereafter) was applied to prioritize such batteries. In this paper, we address the following question: would it be possible to obtain the same prioritization using a simpler approach? In this regard, we are focused on an approach that relies on assigning score intervals (rather than single values) to the alternatives and compares them using a possibility degree formulae (we shall denote as I+P in the sequel). That approach’s main advantage is that it does not require explicit weights but it only relies on a linear ordering of criteria to reflect the user’s preferences, instead. Our results show that the prioritization obtained by means of I+P, A+T, and a simple additive weighting scheme (SAW) are nearly identical, thus providing a positive response to the question posed above.
