A multi-criteria decision making approach for public lighting system selection

Abstract

There are numerous and different ways to design an energy efficient street lighting system, but not always the best technical solution is the optimal economic solution as well. In this paper, we used two distinct software tools in order to obtain the optimal technical and economic solution for selecting street lighting technology. The first software used was DIALux, which is frequently applied in this field, assisting designers in choosing the most appropriate electrical installations and evaluating the technical performance of the chosen solutions. This tool determined the street lighting system variants for which there are predetermined configurations, so that the lighting parameters obtained are in accordance with the normative requirements of the lighting classes in which the roadways are included. Different ways of locating the luminaires and other parameters were changed to reach the best version that meets the qualitative requirements of the lighting technology. The second software used was the one developed by the authors, based on ELECTRE III method, which evaluated the technical solutions returned by DIALux against several criteria, taking into account the designer's preferences and constraints. The optimal technical and economic solution was obtained after ranking the variants by their performance at each criterion. The simulation experiment and the results returned suggested that the combination of the two software tools is comprehensive and effective and it can be used in this type of decisions at large scale.

“…Carli et al [8] develop a multi-criteria decision-making tool to support the public decision maker in optimizing energy retrofit interventions on existing public street lighting systems. Cristea et al [9] propose a multi-criteria decision-making approach for selecting optimal technical and economic solution for public lighting system. Beccali et al [10] propose a multi-objective methodology (including lighting, energy and economic parameters) for street lighting systems refurbishment evaluation in small/medium sized Italian towns.…”

An analysis of the applications of Analytic Hierarchy Process (AHP) for selection of energy efficiency practices in public lighting in a sample of Brazilian cities

“…Specifically in the context of public lighting, some examples of the use of multi-criteria decision making include the application to rank technical alternatives, to identify sets of optimal retrofit actions and support municipalities and their local decision makers (Carli et al, 2018;Carli et al, 2019;Cristea et al, 2018). However, there is a lack of studies focusing on the use of the AHP method in this sector and with particular emphasis in sustainable management rather than in technical aspects.…”
