ALGORITMO PER LA VALUTAZIONE OGGETTIVA DELLE BUONE PRASSI

Il lavoro su cui qui si riferisce ha tratto spunto dall’iniziativa – supportata da Inail Piemonte – del concorso “meno carta più sicurezza”, un concorso nato per valorizzare le buone prassi vantaggiose anche in termini di gestione economica dei rischi ed estendibilità a situazioni assimilabili. Sin dalle prime fasi di attività della giuria, ci si è resi conto della mancanza di metodiche formalizzate di valutazione, essendo la maggior parte dei criteri adottati a livello nazionale ed europeo, basati su un approccio qualitativo, non esente da valutazioni soggettive. Inail Piemonte e Politecnico di Torino hanno, quindi, ritenuto utile impostare un metodo formalizzato per: a) individuare un criterio di organizzazione dei dati di ingresso, b) identificare nei progetti parametri valutabili, oggettivi e numericamente quantificabili, c) sviluppare un algoritmo di elaborazione dei valori di detti parametri, per una valutazione motivata delle proposte. Detto metodo è stato testato su una serie di casi reali tratti dal citato concorso e sviluppato in forma di tecnica computer assistita

Spatial risk assessment and the protection of cultural heritage in southern Tajikistan

Growing digital documentation of cultural heritage resources yielded from an increasing number of international projects, calls for the development of formal computational approaches to assess the risks that this invaluable material heritage is exposed to. This paper proposes a nuanced case-control approach to the risk assessment developed by the Central Asian Archaeological Landscape (CAAL) project for an area in southern Tajikistan. A number of statistical methods are applied for the spatial modelling of the risk to the cultural heritage across the study area and for the assessment of the local scenarios of potential archaeological features already affected by natural and human threats. The value of this formal approach is in its flexible applicability to diverse regional and national settings, as well as in its capability of being updated and repeated within the same territory. This provides local stakeholders, heritage professionals, and local authorities, with a useful tool to develop a risk management plan that includes quantitative as well as qualitative spatial assessments

Anti-collision systems in tunneling to improve effectiveness and safety in a system-quality approach: A review of the state of the art

Tunnelling and underground construction operations are often characterized by critical safety issues mainly due to poor visibility and blind spots around large vehicles and equipment. This can lead to collisions between vehicles or between vehicles and pedestrians or structural elements, causing accidents and fatalities. To improve the OS&H conditions, it is important to investigate the possible introduction of innovative techniques and technologies to reduce the occurrences and consequences of shared spaces (spaces used by both vehicles and pedestrians). For this reason, research was conducted to investigate the possible use of different technologies of anti-collision systems in tunnelling operations. First, to achieve this goal, an extensive review of the literature was carried out in accordance with the PRISMA statement to select the current techniques and technologies used by general anti-collision systems in civil and mining construction sites. Then, the operating principles, the relative advantages and disadvantages, combinations, and costs were examined for each of these. Eight types of systems and many examples of applications of anti-collision systems in underground environments were identified as a result of the analysis of the literature. Generally, it was noted that the anti-collision techniques available have found limited application in the excavation sites of underground civil works up to the present day, though the improvement in terms of safety and efficiency would be considerable
