Decision making in energy planning: The electre multicriteria analysis approach compared to a fuzzy-sets methodology
1998
Every planning activity generally requires to make some choices. After a preliminary analysis of the sector under examination, a forecast of trends of input-output items, the planner must define an action plan voted to arrange all the strategies and specific interventions able to fit demand and supply during the planned time. The redaction of an action plan implies a strong effort in order to synthesize either suggestions coming from the analysis phases either all the constraints linked to technical choices. In the same time, a large number of "external" variables plays a role in orienting decision making. Some of these can be handled by numerical models (economic cost-benefit analyses, mar…
Re-examining the rare and the lost : a review of fossil Tortricidae (Lepidoptera)
2018
We re-evaluate eleven fossils that have previously been assigned to the family Tortricidae, describe one additional fossil, and assess whether observable morphological features warrant confident assignment of these specimens to this family. We provide an overview of the age and origin of the fossils and comment on their contribution towards understanding the phylogeny of the Lepidoptera. Our results show that only one specimen, Antiquatortia histuroides Brown & Baixeras gen. and sp. nov., shows a character considered synapomorphic for the family. Six other fossils ( Electresia zalesskii Kusnezov, 1941; Tortricidrosis inclusa Skalski, 1973; Tortricites skalskii Kozlov, 1988; Tortricibaltia d…
ELECTRE TRI-based approach for sorting projects portfolio: Focus on the European strategy
2018
The European Framework Programme for Research and Innovation aims to facilitate the collaboration between public and private sectors in delivering innovation. To achieve this goal, Union Research and Innovation Programme provides various financial instruments, among which the Horizon 2020 is one of the most significant. Since its implementation, the Horizon 2020 has stimulated the interest of several research organizations making the partnerships among companies their core business for improving local economy. In this context, technological districts are the main proponents of research and innovation spreading in the local territory. In Sicily, the AgroBioPesca district exploited these oppo…
Towards more equity concerning quality of Urban Waste Management services in the context of cities
2018
Abstract An innovative combined evaluation approach is proposed in the present paper to deal with the issue of the performance measurement and comparison of Urban Waste Management (UWM) services in the context of cities. The ELECTRE III method is initially considered as tool able to execute a multi-criteria analysis aimed at ranking UWM systems based on their integration and sustainability levels. The latter are comprehensively evaluated via the recently developed “Wasteaware” Integrated and Sustainability Waste Management indicators framework, which takes into account physical components and governance aspects of UWM systems. Then, on the basis on ELECTRE III results, a practical gaps inve…
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 …
SMAA-TRI
2007
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, such as criteria weights, thresholds, category profiles, and lambda cutting level, 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. SMAATRI allows ELECTRE TRI to be used with imprecise, arbitrarily distributed values for weights and the lambda cutting level. The method consists of analyzing through Monte Carlo simulation finite spaces …
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…
Insight in NLO Polymer Material Behavior from Langevin Dynamic Modeling of Chromophore Poling
2011
Calculation of chromophore polar order, i.e. the polarization of nonlinear optically (NLO) active polymers poled by external field, is challenging. One possible solution is to reproduce the orientation polarization of chromophores under external field using Langevin dynamics (LD) molecular modeling. The present work investigates the influence of chromophore dipole moment, density and field extent on NLO efficiency and polarization/relaxation dynamics. Results of simulations convince us, that the method is applicable for modeling real NLO polymers. In the spotlight of this investigation we would like to describe a NLO polymer as a “ferrofluid” where chromophores are active particles or elect…
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…
The ELECTRE I method to optimise GPR data processing analyses for maintenance of water networks
2017
Management of water supply systems (WSSs) can be effectively pursued by means of data processing techniques based on Ground Penetrating Radar (GPR) image mining. This approach enables to collect different graphical representations of WSS buried elements on the basis of which planning maintenance interventions, with the objective of improving the overall condition of the system. This paper proposes to support this kind of techniques by means of a multi criteria decision making (MCDM) point of view. In particular, the ELECTRE I method is suggested to treat results coming from the application of different techniques. A real case study is applied with relation to a set of four alternatives, whi…
