This study aims to model scale effects in nano-beams under torsion.

The elastostatic problem of a nano-beam is formulated by a novel stress-driven nonlocal approach.

Unlike the standard strain-driven nonlocal methodology, the proposed stress-driven nonlocal model is mathematically and mechanically consistent. The contributed results are useful for the design of modern devices at nanoscale.

The innovative stress-driven integral nonlocal model, recently proposed in literature for inflected nano-beams, is formulated in the present submission to study size-dependent torsional behavior of nano-beams.

The paper aims to analyze the structural integrity of an existing offshore platform located in the Northern Adriatic Sea, followed by the topside decommissioning and the re-utilization of the jacket as a wind turbine support. The structural integrity assessment against the in-place and the long-term actions is accomplished by using a reduced basis finite element method (RB-FEA) software program assessing the capability of the jacket to be used as a support for wind turbines at the end of its life cycle as oil and gas (O&G) platform.

The project starts by modeling the jacket, and subsequently, the structural analyses for the in-place loads in operative and extreme conditions are performed. Then, the fatigue analysis is carried out in order to define the cumulative damage necessary to evaluate the possibility to use the jacket as a wind turbine support.

The results show that the jacket, at the end of the service life as O&G platform, is able to withstand the loads produced by the installation of the wind turbine since the analyses are satisfied even with the conservative approach used which overestimates the thickness loss assuming a linear increasing value during the service life.

Because of the chosen approach, the study presents some limitations, especially concerning the real state of the platform which has been defined considering the thickness loss only. Additionally, a 1D model was used to perform the analyses, and hence, a 3D model could help in evaluating the critical points with higher precision.

The assessment of the structure could be improved by modeling a digital twin of the asset allowing a real-time monitoring which, however, involves a huge amount of data to be processed, so a suitable simulation technology must be used.

The RB-FEA proposed by Akselos is suitable to perform the analyses speeding up the processing of the data even in real time.

This paper aims to explore the current state of research on supply chain flexibility (SCF) and mass personalization (MP) to identify the literature findings to date, research gaps and to provide guidelines for future research in this area.

A systematic literature review of 64 papers was undertaken to address the use of SCF as a productive response to MP environments. The methodology used is made up of five steps: formulation of the research questions, identification of studies, selection and evaluation of studies, analysis and synthesis and presentation of the results.

Three main research topics have been identified: personalization levels and flexible processes in supply chain, where flexible processes in supply chain are analysed as a productive response to high levels of MP; supply chain collaborative processes for SCF and MP, where product co-creation and relationships between supply chain members is analysed; and SCF and MP enabling technologies, in which technologies to support MP implementation and SCF are considered. Each of these three main topics have been divided into research lines and research sublines that allowed identifying a positive relationship between the SCF and the MP strategies.

Systematic literature review is a methodology reliable and recommended by a large number of scientific papers. However, it depends on available and accessible research studies and the researcher’s criteria. The selection of certain criteria for inclusion and exclusion of papers introduces publication bias, which should be considered an intrinsic limitation to systematic literature review.

The main literature findings in each research line and subline related to the SCF-MP relationship are identified and analysed. Furthermore, research gaps and further research lines in the SCF-MP area are highlighted. The information presented in this paper improves the literature on the advances in the SCF use as a productive response to MP environments.
