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 …

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 …

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…

Combined fuzzy TOPSIS and AHP-based methodology for the prioritization of maintenance key performance indicators: Application to an oil refinery plant

2017

A Maintenance Performance Measurement model based on the use of Maintenance Key Performance Indicators (MKPIs) is proposed in the present paper. Referring to a specific industrial context, a multi-level hierarchical structure is firstly designed to highlight the most meaningful perspectives which affect the maintenance performance. Then, MKPIs selected from the literature or properly formulated to detail some particular perspective of the investigated maintenance process are assigned to the hierarchical framework and prioritized by a Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) and Analytic Hierarchy Process (AHP)-based approach.

A combined interval-valued ELECTRE TRI and TOPSIS approach for solving the storage location assignment problem

2019

Abstract Efficiency and effectiveness of logistic activities, in general, and of distribution networks, in particular, are largely influenced by the way warehouses operate as nodes of these networks. In recent years, warehouse management has undergone major changes due to the increase of e-commerce and competition in time-reduction. Despite that, logistic costs of warehouse processes (e.g. receiving, storage, order picking and shipping, etc.) are still often high. Referring to the order picking process, related activities may be optimized by a proper assignment of products to storage locations. In the literature, this problem is known as Storage Location Assignment Problem (SLAP). Due to th…

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…

Evaluation of routing policies using an interval-valued TOPSIS approach for the allocation rules

2021

Abstract The success of warehouse management in a supply chain widely depends on an efficient and effective retrieve of customer orders, which is known as the picking process. This paper investigates various routing policies of pickers under two different allocation methods of items in a warehouse of fixed layout, and evaluates their performance in terms of the resulting travel distance by means of a simulation approach. The allocation strategies taken into account are the random storage and a multi-criteria approach, called Interval-Value TOPSIS (IV-T), which is expressively proposed in this paper as a new way to solve the storage allocation problem of items in a warehouse. Because of the …

DINESERV along with fuzzy hierarchical TOPSIS to support the best practices observation and service quality improvement in the restaurant context

2019

Abstract The present work proposes a new Multi-Criteria-Decision-Analysis (MCDA)-based approach integrating the DINESERV model along with the hierarchical TOPSIS method as measurement tool for evaluating quality in the restaurant services context. More in detail, on the basis of the DINESERV theoretical framework of the restaurant service quality, hierarchical TOPSIS is applied to compare quality of restaurant services. Actually, due to the prioritization process of hierarchical TOPSIS, investigated services providers are consistently and effectively assessed against criteria and sub-criteria of DINESERV, so allowing the identification of both best practices and weaknesses of delivered serv…
