Ranking of shelf life models based on smart logistic unit using the ELECTRE III method
2015
The aim of this paper is the evaluation of Shelf Life (SL) models based on Smart logistic unit to support the management of the food supply chain in order to guarantee the shelf life of products in agreement with logistic efficiency and system sustainability. For this purpose, the main shelf life equations based on parameters that influence the quality of perishable products were defined and the correspondent acquiring and gathered system has been developed. The selection of the optimal SL model was carried out by means of the multi-criteria decision-making procedure ELECTRE III.
The sustainability of olive orchard planting management for different harvesting techniques: An integrated methodology
2019
Abstract The globalization of the olive oil market has caused greater competitiveness in terms of olive oil quality and production costs and the main countries interested in olive growing, have introduced efficient planting design and horticultural techniques in order to meet these requirements. In this paper the sustainability of olive orchard planting management for different olive fruit-harvesting methods has been assessed on the basis of the data gathered by the Geographic Information System and processed using a Multi-Criteria Decision Making Analysis. In particular, three different agronomic scenarios have been analyzed and a specific cultivar has been considered in order to ensure th…
ELECTRE TRI to classify items with respect to maintainability criterion
2014
The paper aims to suggest a methodology able to support the analyst in the assessment process of items on the base of a criterion inspired to the maintainability parameter and in the successive assignment phase of the items in the predefined classes. The maintainability involves the continuous improvement of a system in order to improve the ability to maintain or improve the reliability of the analyzed system. In particular, the last one is the probability that a failed system will be restored to specified conditions within a given period of time when maintenance is performed according to prescribed procedures and resources. The faced case in this research regards the software maintenance, …
Managerial decision making for complex service systems Optimization
2021
The present paper deals with managerial decisions for Predictive Maintenance (PrdM) of complex service systems. We propose a Multi-Criteria Decision-Making (MCDM) approach aimed at sorting those failure modes potentially involving critical components into risk classes for interventions prioritisation and maintenance control. In this context, the sorting technique ELimination Et Choix Traduisant la REalité (ELECTRE) TRI is applied to support in finding the root causes that can be eliminated for failure prevention and/or minimization. This methodology presents the advantage to not rely on comparisons (as well as on their transitivity) between pairs of elements, simplifying computations for co…
ELECTRE TRI-based approach to the failure modes classification on the basis of risk parameters: An alternative to the risk priority number
2017
Proposing an ELECTRE TRI-based approach for the failure modes classification into predefined and ordered risk classes.Direct identification of failure modes on which performing the corrective actions with priority.Easy definition of risk classes on the basis of DMs expertise and perception of the industrial context considered.Application to dairy manufacturing processes. Failure Mode and Effects Analysis (FMEA) is an engineering technique aimed at the detection of potential failures, their causes and consequences on the system/process under investigation. When used for the failure modes prioritization, FMEA is also referred to as Failure Mode, Effects and Criticality Analysis (FMECA). In tr…
The Multicriteria Electre III Model Applied to the Evaluation of the Placement of University Graduates
2010
During the last years the Italian university system has been undergoing a reform process regarding issues of governance such as the progressive financial autonomy of the University (art. 5, law 537/24 December 1993) and the reshape of the academic curricula (law 509/99 and 270/04). The most obvious result of this complex process has been the challenging attempt to manage a necessary change in a context of limited financial resources. In order to encompass the composite features of an efficient and effective management of resources, features of high relevance for the full accomplishment of the reform benchmarks, one has to take into account the academic organisation’s objectives, so that to …
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…
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…
Improved FMECA for effective risk management decision making by failure modes classification under uncertainty
2022
Failure Mode, Effects, and Criticality Analysis (FMECA) is a proactive reliability and risk management technique extensively used in practice to ensure high system performance by prioritising failure modes. Owing to the limitations of traditional FMECA, multi-criteria decision-making methods have been employed over the past two decades to enhance its effectiveness. To consider the vagueness and uncertainty of the FMECA evaluation process, an interval-based extension of the Elimination et Choice Translating Reality (ELECTRE) TRI method is proposed in the present paper for the classification of failure modes into risk categories. Therefore, ratings of failure modes against risk parameters are…
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 …
