A proposal for sorting a projects portfolio through the ELECTRE TRI method focused on the European strategy

2019

In recent years, the partnerships between private companies and public organizations are becoming key elements for improving local development, territorial competitiveness, and delivering innovation. These collaborations are widely promoted by the European Framework Programme for Research and Innovation thanks to the provision of several instruments, such as Horizon 2020. In this context, competitiveness's improvement of the territory employing research and innovation actions is supported by the technological districts. In Sicily, the AgroBioPesca district has attempted a strategic action named "Call for ideas" in order to design its own roadmap for research and innovation in the agri-food …

Supporting public decision process in buildings energy retrofitting operations: the application of a Multiple Criteria Decision Aiding model to a cas…

2020

Abstract The challenge of promoting sustainable cities and reaching the objectives developed by the European Green Deal includes the renovation of the building sector, as it is responsible for 40% of energy consumption in Europe. Regional or local public administrations have to allocate their financial resources for improving the energy performances of their building stock and to face a multidimensional problem, where different aspects – such as energy efficiency, financial-economic feasibility and environmental protection – have to be harmonized. The present study proposes a Multiple Criteria Decision Aiding model, which includes the ELECTRE TRI-nC method, for supporting the public decisio…

A multi criteria decision making approach to support the risk management: a case study

2016

Project risk management plays a fundamental role in the project management field. Project objectives may dynamically change in time, hence it is not easy to satisfy them, especially when related to complex projects. In detail, they can be subjected to several and different risk conditions which have an important impact on the project success. In this context, multi-criteria decision making (MCDM) methods are effective tools to carry out the risk management. In particular, the present research proposes the use of MCDM with a specific focus on the ELECTRE TRI method. The last one is able to evaluate and assign projects under analysis into ordered and different risk classes. The purpose consis…

Fuzzy ServPerf model combined with ELECTRE III to comparatively evaluate service quality of international airports in Sicily

2015

In this paper a new approach was proposed so as to comparatively evaluate the quality of service alternatives. In particular, a fuzzy extension of the ServPerf service conceptual model was considered to estimate quality scores of fundamental service criteria, whereas the non-compensative multi-criteria decision-making ELECTRE III method was employed to point out the quality ranking of service alternatives on the basis of which the comparative service quality analysis was performed. In order to show the effectiveness of the proposed approach, an empirical study concerning service quality evaluation of the three international airports in Sicily (Italy) was conducted with detailed proposals fo…

Comparing multicriteria methods in the context of environmental problems

1998

Abstract The present paper gives an analysis of the use of ELECTRE III, PROMETHEE I, II, and SMART decision-aids in the context of four different real applications to environmental problems in Finland. These methods are widely used decision-aids in the real planning processes. The purpose of this study is to define the differences of these methods and the results obtained with them, and in this way also to consider their applicability in aiding environmental decision-making. Furthermore, a comparison of the methods based on a set of randomly generated problems is carried out. The choice in practice will not be easy; PROMETHEE does not differ much from SMART with linear value functions, and …

The choice of a solid waste management system using the Electre II decision-aid method

1995

A multicriteria decision-aid method, Electre II, was applied to the real choice process of a solid waste management system in the Uusimaa region, Finland. The criteria used were chosen by a supervision group. The weights of the criteria were defined by the managers of environmental and technical affairs of each municipality in Uusimaa, Finland. The use of the Electre II method leads us to recommend centralized incineration as the best municipal solid waste management system for the planning region. However, the second best alternative, intermediate RDF combustion with intermediate landfilling was finally chosen by the municipalities.

ELECTRE III and IV Decision Aids in an Environmental Problem

1997

This paper gives a description and analysis of the use of ELECTRE III and IV decision aids in the context of choosing a solid waste management system in two different real applications in Finland. Both methods fit this context well in general, since the problem involves many criteria and many ‘decision makers’. The available data are imprecise, which also favours the use of outranking methods. In addition to the real applications, we also study the choice behaviour offered for decision makers in connection with these methods by looking at some test results obtained from randomly generated problems. In general, the results of ELECTRE III and IV do not differ substantially from those from the…

A stochastic method for robustness analysis in sorting problems

2009

ELECTRE TRI is a multiple criteria decision aiding sorting method with a history of successful real-life applications. In ELECTRE TRI, values for certain parameters have to be provided. We propose a new method, SMAA-TRI, that is based on stochastic multicriteria acceptability analysis (SMAA), for analyzing the stability of such parameters. The stability analysis can be used for deriving robust conclusions. SMAA-TRI allows ELECTRE TRI to be used with uncertain, arbitrarily distributed values for weights, the lambda cutting level, and profiles. The method consists of analyzing finite spaces of arbitrarily distributed parameter values. Monte Carlo simulation is applied in this in order to desc…

A multi-objective approach to facility layout problem by genetic search algorithm and Electre method

2006

Abstract Classical approaches to layout design problem tend to maximise the efficiency of layout, measured by the handling cost related to the interdepartmental flow and to the distance among the departments. However, the actual problem involves several conflicting objectives hence requiring a multi-objective formulation. Multi-objective approaches, recently proposed, in most cases lead to the maximisation of a weighted sum of score functions. The poor practicability of such an approach is due to the difficulty of normalising these functions and of quantifying the weights. In this paper, this difficulty is overcome by approaching the problem in two subsequent steps: in the first step, the P…
