This work addresses the experimental and numerical study of a stepped planing hull related fluid dynamics phenomena typically occurring in unwetted aft body area behind step. In last few years, interest high-speed crafts, with low weight-to-power ratios, has been increasing significantly, and, such context, naval architects have orienting toward solution. Stepped hulls ensure good dynamic stability seakeeping qualities at high speeds. is mainly due to reduction wetted area, which caused by...

Industrial and manufacturing systems have a huge impact on energy resources consumption, the emissions to environment and, hence, society. For these reasons, Sustainable Manufacturing is one of most important issue address for reaching Development our In this frame, maintenance process that must ensure availability, reliability safety equipment, has key role sustainable operations. However, how can integrate sustainability goal contribute objective not clearly defined: few studies addressing...

In the context of marine application computational fluid dynamic (CFD), it is well known that numerical simulations planing craft are significantly less reliable than displacement ships. For this reason, important to perform a comprehensive approach verification and validation (V&V) methodology procedures for simulating CFD craft. first part paper, an assessment accuracy effectiveness different simulation setups techniques performed. second part, results V&V study reported three hull...

The fourth industrial revolution is affecting the workforce at strategical, tactical, and operational levels it leading to development of new careers with precise specific skills competence. implementation enabling technologies in context involves types interactions between operators machines, that transform have significant implications for nature work. incoming generation Smart Operators 4.0 characterised by intelligent qualified who perform work support interact collaborative robots...

Collaborative robots are an important enabling technology of Industry 4.0. The interaction between humans and robots, called Human-Robot Collaboration (HRC), aims to improve system performance. However, it is necessary investigate in depth the effects this close on workers identifying individual factors involved discerning which them affect introduction HRC a manufacturing system. purpose paper analyze collaboration how operator's work affected by HRC. A scoping review was conducted identify...

Artificial Intelligence (AI) and Machine Learning (ML) represent popular topics of Industry 4.0. The use these techniques, which are evolving rapidly in both academia practice, can bring many benefits to production systems, such as enabling resilience improving sustainable growth. However, given the effort needed implementation AI/ML terms data quality employee skills, potential has not yet fully materialized context manufacturing Micro, Small, Medium Enterprises (MSMEs), could improve their...

Industrial companies are among the largest responsible of materials and energy flows in an environment where natural resources running out impacts human activities still rising. Consequently, last few years, research is focusing on new paradigm sustainable manufacturing, which aims to develop production processes, innovative technologies, tools for evaluating economic, environmental, social industrial assets. In this context, maintenance process, necessary ensure availability, reliability,...

The uncertainty in the supply chains (SCs) for manufacturing and services firms is going to be, over coming decades, more important companies that are called compete a new globalized economy.Risky situations considered trying individuate optimal positioning of order penetration point (OPP).It aims at defining best level information client's back through several chain (SC) phases, i.e. engineering, procurement, production distribution.This work system dynamics model assess competitiveness...

Purpose Poor maintenance management leads to non-negligible economic, environmental and social impacts obstacles the sustainable manufacturing paradigm. Studies evaluating on sustainability underline growing interest in topic, but reports industrial field are lacking. Therefore, this paper investigates environment indicators that companies use for measuring their impacts. Design/methodology/approach In pilot survey study, several stakeholders of production enterprises south Italy were...

The Industry 4.0 paradigm is spreading in logistics processes since integrating technologies tasks guarantees several benefits compared to traditional processes. However, there are still open questions related impacts on the workforce, including problems skills, competence, and ethical social issues. This paper focuses one of main used logistics: Augmented Reality (AR). Based a deductive research approach, which considers well-founded knowledge represented by extant literature mediated...

Human error in manual assembly systems affects system reliability, safety and it is one of the most important causes quality defects. Many researchers have developed methods for Reliability Analysis (HRA) with aim identifying, modeling, quantifying reducing human error, mainly safety-critical industries. This paper addresses reliability analysis systems, where employed workforce currently involved. The main purpose to systematically investigate current state-of-the-art on this topic,...

Purpose: Human factors play an inevitable role in maintenance activities, and the occurrence of Errors (HEs) affects system reliability safety, equipment performance economic results. The high HE rate increased researchers’ attention towards Reliability Analysis (HRA) assessment approaches. In these approaches, various environmental individual influence operators affecting Error Probability (HEP) with a consequent variability success intervention. However, deep analysis such field, often...
