Evaluation of new functional pasta using TOPSIS methodology
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…
Human error contribution to accidents in the manufacturing sector: A structured approach to evaluate the interdependence among performance shaping factors
Since the 1970s, Human Reliability Analysis (HRA) methods have received a great interest for the quantification of the Human Error Probability (HEP) in Nuclear Power Plants (NPPs). To this purpose, the second-generation HRA methods consider contextual and cognitive factors - named Performance Shaping Factors (PSFs) - that may influence the workers’ performance during tasks execution. Despite the recent extension of HRA methods to different fields, only few studies refer to the manufacturing sector. In addition, the majority of contributions assume the independence among PSFs, which may result in an over or under estimation of HEP. Therefore, the present paper focuses on the manufacturing se…
Multi criteria evaluation of a sustainable alkali-activated concrete
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…
A Structured Methodology for the Safety Key Performance Indicator Prioritization: A Case Study
Nowadays, companies have become more and more attentive to the management and evaluation of activities, processes and actions related to the safety in workplaces. This attention stems from both the need to comply with law requirements and to improve the productivity of the company by ensuring the reduction of occupational injuries and diseases. Accordingly, performance evaluation is a fundamental step also theorized by the most important guidelines on Occupational Health and Safety Management Systems (OHSMSs). With this recognition, the present paper provides a methodology to prioritize Safety Key Performance Indicators (SKPIs) starting from an initial set selected from the literature. Refe…
