Multi criteria evaluation of a sustainable alkali-activated concrete
2019
The construction industry is one of the most polluting sectors worldwide. In order to reduce the environmental footprint, novel green materials and processes are being considered by valorising and reusing wastes. This work investigates the production of a novel and sustainable geopolymeric concrete reusing biomass fly ash from kraft paper-pulp industry. In particular, this paper aims to evaluate the best combination of the aggregate granulometry used in the material production. For this purpose, the multicriteria method TOPSIS has been implemented in order to obtain a rank of the concrete specimens. In this approach only mechanical aspects have been considered and future developments will i…
Combined HACCP and TOPSIS-based approach to prioritize risks in the salmon manufacturing process: A case study
2017
The food safety risk assessment is defined by the Codex Alimentarius Commission as the scientific evaluation of known or potential adverse health effects resulting from human exposure to food-borne hazards. Nowadays, the implementation of a systematic and disciplined risk assessment approach in the food safety field is recognized to be a powerful tool for carrying out science-based analyses and for reaching sound consistent solutions to food safety problems. With this recognition, a combined Hazard Analysis and Critical Control Point (HACCP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS)-based approach is proposed in the present paper to prioritize risks of t…
Food safety risk analysis from the producers' perspective: prioritisation of production process stages by HACCP and TOPSIS
2018
[EN] From the manufacturers perspective, the Hazard Analysis and Critical Control Point (HACCP) system nowadays represents the mainly way to implement the food safety risk management in food industries. Nevertheless, the identification and prioritization of hazards as the outcome of the first principle of HACCP is not sufficient to identify production process stages that more significantly and critically contribute to the consumer¿s risks. With this recognition, the present paper proposes a Quantitative Risk Assessment (QRA) approach based on HACCP and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to individuate production process phases on which implementing co…
Multicriteria methods in evaluation of city logistics projects
2017
Multi-criteria decision making (MCDM) methods are chosen among alternatives in order to attain specific objectives. In this research, the purpose of methodology is to provide decision methods for project managers in city logistics. The methodology is combined into two methods consisting of Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). As the result, the criteria for selection are determined by expert opinions, and then assign the weight of criteria by AHP. Finally, TOPSIS method is used to evaluate alternatives which are found prioritized by weight for project , namely project C equal 0.537 , project A equal 0.438 , project B e…
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&
Ocena wiarygodności internetowych serwisów wybranych polskich wyższych uczelni niepublicznych
2019
Celem artykułu jest dokonanie i przedstawienie oceny wiarygodności internetowych serwisów wybranych polskich wyższych uczelni niepublicznych. Koncepcja, metody badań: Sięgając do definicji terminów związanych z pojęciem wiarygodność odniesiono je do serwisów internetowych. Na tej podstawie stworzono konceptualne ramy oceny wiarygodności dla takich serwisów. Ramy te posłużyły do oceny wiarygodności internetowych serwisów wybranych wyższych uczelni niepublicznych w Polsce z wykorzystaniem metody sondażowej i oryginalnego narzędzia. Ranking wiarygodności badanych serwisów internetowych utworzono wykorzystując metodę TOPSIS. Wyniki i wnioski: W artykule pokazano, że zestaw cech i kryteriów używ…
Application of the fuzzy TOPSIS method in management of food supply chain = Zastosowanie rozmytej metody TOPSIS w zarządzaniu łańcuchem dostaw żywnoś…
2019
W pracy przedstawiono wielokryterialną metodę podejmowania decyzji: rozmytą metodę TOPSIS. Jest to alternatywa dla metod AHP, TOPSIS, ELECTRE lub PROMETHEE. W pracy przedstawiono możliwość zastosowania rozmytej metody TOPSIS w zarządzaniu łańcuchem dostaw żywności (FSCM). W tym celu przedstawiono krótki przegląd literatury. Następnie przedstawiono rozmytą metodę TOPSIS, na końcu artykułu pokazano możliwość zastosowania metody do rozwiązania problemu.
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…
