Management Perspectives on Industrial Heritage: an Exploratory Research

The current research project focuses on the analysis of the critical issues of industrial heritage management in Italy and the preservation of organizational history within the reuse projects of former industrial sites. The organizational and managerial perspective is crucial on two levels. Firstly, it is important in the analysis of the original significance of the site, and in particular its organizational history, and its conservation within the new regeneration strategy. Secondly, it is crucial at the phase of management of reuse projects and its feasibility and sustainability analysis. Based on the analysis of the literature, a unique classification of the reuse strategies that can be implemented in order to regenerate former industrial sites has been formulated. The exploratory research thus adapts a multiple case study design. Eight Italian case studies have been chosen, one for each type of regeneration strategy. Each case study is explored as a stand-alone entity through the analysis of the local differences and idiosyncrasies of the specific context, the factors that stood behind the choice of the reuse strategy and the way the reuse project evolved through the years. Then, the current management of each reuse project is analysed. The narration and musealization of the organizational history is investigated through the spatial dimension, the level of content and the level of expression. Secondly, the case studies are compared through a cross-case analysis from three different perspectives: issues on the phase of preparation and implementation of the reuse projects, critical issues behind the current management of new projects and issues on the ways of preservation and narration of organizational history within the new project. The research shows that all regeneration strategies are affected by the conflict between preservation and change, by the issue of materiality and selectivity.

Models and methods for damage and quantitative risk assessment of Natech scenarios

Natural events are a widely recognized hazard for industrial sites where relevant quantities of hazardous substances are handled, due to the possible generation of cascading events resulting in severe technological accidents (Natech scenarios). Natural events may damage storage and process equipment containing hazardous substances, that may be released leading to major accident scenarios called Natech events. The need to assess the risk associated with Natech scenarios is growing and methodologies were developed to allow the quantification of Natech risk, considering both point sources and linear sources as pipelines. A key element of these procedures is the use of vulnerability models providing an estimation of the damage probability of equipment or pipeline segment as a result of the impact of the natural event. Therefore, the first aim of the PhD project was to outline the state of the art of vulnerability models for equipment and pipelines subject to natural events such as floods, earthquakes, and wind. Moreover, the present PhD project also aimed at the development of new vulnerability models in order to fill some gaps in literature. In particular, a vulnerability model for vertical equipment subject to wind and to flood were developed. Finally, in order to improve the calculation of Natech risk for linear sources an original methodology was developed for Natech quantitative risk assessment methodology for pipelines subject to earthquakes. Overall, the results obtained are a step forward in the quantitative risk assessment of Natech accidents. The tools developed open the way to the inclusion of new equipment in the analysis of Natech events, and the methodology for the assessment of linear risk sources as pipelines provides an important tool for a more accurate and comprehensive assessment of Natech risk.

A distributed middleware for IT/OT convergence in modern industrial environments

The modern industrial environment is populated by a myriad of intelligent devices that collaborate for the accomplishment of the numerous business processes in place at the production sites. The close collaboration between humans and work machines poses new interesting challenges that industry must overcome in order to implement the new digital policies demanded by the industrial transition. The Industry 5.0 movement is a companion revolution of the previous Industry 4.0, and it relies on three characteristics that any industrial sector should have and pursue: human centrality, resilience, and sustainability. The application of the fifth industrial revolution cannot be completed without moving from the implementation of Industry 4.0-enabled platforms. The common feature found in the development of this kind of platform is the need to integrate the Information and Operational layers. Our thesis work focuses on the implementation of a platform addressing all the digitization features foreseen by the fourth industrial revolution, making the IT/OT convergence inside production plants an improvement and not a risk. Furthermore, we added modular features to our platform enabling the Industry 5.0 vision. We favored the human centrality using the mobile crowdsensing techniques and the reliability and sustainability using pluggable cloud computing services, combined with data coming from the crowd support. We achieved important and encouraging results in all the domains in which we conducted our experiments. Our IT/OT convergence-enabled platform exhibits the right performance needed to satisfy the strict requirements of production sites. The multi-layer capability of the framework enables the exploitation of data not strictly coming from work machines, allowing a more strict interaction between the company, its employees, and customers.
