Multi-Criteria Evaluation of Health Care Performance in the Czech Republic and Poland
2022
Health is considered as the most important value in a person's life. It follows, therefore, that health care evaluation is very important aspect from a societal point of view. Evaluating of health care is an essential component to determine the functioning of national health care system and to improve its performance. The paper is focused on the evaluation and comparison of health care performance in the Czech Republic and Poland based on a multicriteria analysis. The research is monitoring the selected health care indicators for the period of six years from 2014 to 2019. The obtained data are processed by TOPSIS method. the output of the research is the ranking of the countries of the Euro…
From microbial proteomics to synthetic biology: Amycolatopsis balhimycina case
2012
Actinomycetes, filamentous Gram-positive bacteria, are usually exploited as bio-farms naturally producing a wide range of small biologically active metabolites, such as antibiotics, extensively used in medicine, food-industry, chemistry and bio-remediation strategies. The development of high throughput technologies, like proteomics, allows functional genomic studies aimed at shedding light on molecular mechanisms controlling the production of useful compounds and macromolecules. Differential proteomic analyses, performed by using Two Dimensional PolyAcrylamide Gel Electrophoresis (2D-PAGE) coupled to mass spectrometry (MS) procedures, revealed novel links between balhimycin production (a va…
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…
Decision-Making Tools to Manage the Microbiology of Drinking Water Distribution Systems
2020
[EN] This paper uses a two-fold multi-criteria decision-making (MCDM) approach applied for the first time to the field of microbial management of drinking water distribution systems (DWDS). Specifically, the decision-making trial and evaluation laboratory (DEMATEL) was applied removing the need for reliance on expert judgement, and analysed interdependencies among water quality parameters and microbiological characteristics of DWDS composed of different pipe materials. In addition, the fuzzy technique for order preference by similarity to ideal solution (FTOPSIS) ranked the most common bacteria identified during trials in a DWDS according to their relative abundance while managing vagueness…
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…

A multi-objective and multi-criteria approach for district metered area design: water operation and quality analysis
2019
Water distribution network (WDN) operation may be improved by district metered area (DMA) design [1]. A first step to create DMAs uses graph theory and non-supervised learning, where physical features of the WDN, such as node coordinates, elevation and demand, are used for clustering purposes [2]. A second step is related to the necessary isolation of the clustered elements. For isolation purposes, it is important to determine the DMA entrances and, consequently, the needed cut-off valves. Closure of pipes and definition of DMA entrances can be set as an optimization problem with the costs associated to the valves, which are linked to pipe diameters, as a primary objective. However, placeme…

Clean Agent Selection Approached by Fuzzy TOPSIS Decision-Making Method
2008
Abstract. It is well known that halons are ozone-depleting substances and their release into the atmosphere has contributed in the last decades to the reduction in the ozone layer. In consequence to the Montreal Protocol, an international agreement designed to gradually eliminate the use of such substances, fire protection industry researchers faced the challenge of finding effective solutions to replace halon extinguishers. This research aims to provide a method to support the decision maker in the selection of the most suitable extinguisher substance for a specific application. According to such framework, a set of quantitative and qualitative criteria has been established in the decision…
