Selection of novel geopolymeric mortars for sustainable construction applications using fuzzy topsis approach
2020
Construction is recognized as one of the most polluting and energy consuming industries worldwide, especially in developing countries. Therefore, Research and Development (R&
Evaluation of new functional pasta using TOPSIS methodology
2017
Nowadays several studies are focused on the introduction of Opuntia in frequently consumed foods, such as pasta and bakery products. Food products containing Opuntia are in fact able to reduce body weight and plasma LDL cholesterol, lipids and glucose. Foods, that may provide health and wellness benefits, are known as "functional foods". The aim of this paper is the evaluation of a new functional pasta comprising Opuntia able to guarantee health benefits without altering the organoleptic properties of the final product. For this purpose, a set of samples, based on different concentration of Opuntia solution and process parameters, was prepared for the production of short and long pasta. The…
A Prioritisation Model Aiding for the Solution of Illegal Buildings Problem
2016
In Italia, in particolare nelle aree del Sud, la costruzione di edifici e insediamenti abusivi è un problema importante e annoso che rimane irrisolto a dispetto di tre condoni edilizi. Ne deriva che le autorità pubbliche si trovano ad affrontare il problema della demolizione di un ingente numero di edifici, come prescritto dalla legislazione in materia. Ragioni di natura sociale e finanziaria impongono tuttavia l’esecuzione degli ordini di demolizione in maniera poco concentrata nel tempo, evidenziando il problema decisionale di stabilire un ordine di priorità relativo agli edifici interessati. Questa situazione preoccupante è divenuta oggetto di uno specifico disegno di legge che propone e…
A fuzzy multi-criteria decision-making methodology to optimise olive agro-engineering processes based on geo-spatial technologies
2016
In southern Italy, the olive oil sector is an important part of the primary sector and its development requires support from research to ensure its sustainability. This work proposes the first step for set up a decision support system (DSS) for establishing mechanisation in agricultural operations for different olive groves. To contribute to this goal researches have been carried out to test the ability of remote sensing (RS) and geographic information system (GIS) to map olive groves and their agronomic characteristics. In detail, this study aimed to classify olives grove areas in terms of agronomic suitability and detect horticultural characteristics of olive groves in order to develop a …

Multi-Criteria Decision Making support system for pancreatic islet transplantation
2011
Pancreatic islet transplantation consists of replacing insulin-producing cells to restore normal glycemia in diabetic patients. This is a minimal invasive procedure that has been proved successful. Unfortunately unpredictability of islet transplant outcome remains a frustrating and costly issue limiting the clinical implementation of this procedure. Multiple variables are involved in the procedure and assessment is subjective to individual operators. The aim of this study was to generate a system expressing the probability of transplant success in relation to four classes of identified variables (donor, organ, isolation and recipient). We have proposed the utilization of Multi-Criteria Deci…
Allocation of logistic risk-investment in public-private-partnership – use of fuzzy TOPSIS method
2018
Appropriate risk assessment related to the project, and then its distribution between partners is the core of cooperation in the framework of public-private partnership (PPP). Risk analysis for investment project in the PPP formula includes: preliminary identification of risks associated with the investment, preliminary assessment and forecast of probability of occurrence of risks in the recommended option of investment implementation, initial analysis of the distribution of risks between a public and private entity depending on the legal and organizational model adopted, including the determination of the appropriate separation between the parties to the contract. The article presents the …
A Multi-Criteria Group Decision To Support The Maintenance Service: A Case Study
2015
The present paper wants to propose a methodology to support a group of decision makers into the choice of actions, to implement on a multi-component system, regarding the maintenance service. The choice has to be made on the basis of several criteria, namely the total maintenance cost, the system unavailability and by considering the maintenance actions feasibility. In particular, with the aim to select the maintenance service that represents for the group the best comprise among the criteria to satisfy, the proposed methodology consists of two multi-criteria decisions methods to apply in two successive phases. The first one regards the application of the Analytic Hierarchy Process (AHP) to…
Sustainable vehicle routing based on firefly algorithm and TOPSIS methodology
2019
Abstract In a sustainable management of logistics, transportation plays a crucial role. Traditionally, the main purpose was to solve the Vehicle Routing Problem minimizing the cost associated with the travelled distances. Nowadays, the economic profit cannot be the only driver for achieving sustainability and environmental issues have to be also considered. In this paper, to satisfy the intricate limits involved in real vehicle routing problem, the study has been structured considering different types of vehicles in terms of maximum capacity, velocity and emissions, asymmetric paths, vehicle-client constraints and delivery time windows. The firefly algorithm has been implemented to solve th…
