Abstract
The Human-Centric SMED (H-SMED) is an evolution of the classical methodology introduced by Shingo to manage the setup process, which is particularly suitable for companies where the setup involves activities with high human content, that can be hardly transformed into external operations to be performed during the machine uptime. The H-SMED integrates Industry 4.0 tools, as the MES Data Analysis, Lean Management and Ergonomics with a new attention to the centrality of workers, in order to guide the transition towards the next Industry 5.0. The H-SMED methodology is developed into four phases, devolved to: (1) understanding the changeover process; (2) identifying potential improvements; (3) moving from proposal to practice; (4) training and control, in a continuous improvement cycle. The case study of a world-wide known company in the fashion eyewear industry is proposed to validate the framework, reporting a 44% reduction of setup duration.
Highlights
An effective way to achieve good performances in a changeover process is the implementation of the Single Minute Exchange of Die (SMED) methodology proposed by Shingo
The emerging vision of Industry 5.0 sets the human pillar in the center of the production systems, complementing the development of Industry 4.0 with the new paradigm of “Economy that works for people” [1]
The Human-Centric SMED (H-SMED) framework has been developed as a solution to rethink and lean the setup process, while aligning it with the new concept of Industry
Summary
The European Union has recently introduced the new concept of “Industry 5.0”, where the focus shifts from the technology-driven progress typical of Industry 4.0 to a thoroughly human-centric approach. Requirements, in order to gain better performance This means adopting a sustainability approach, in particular its social dimension, with renewed attention paid to supporting workers in their activities, working in symbiosis with new technologies as a fundamental step towards the Society 5.0 [4]. To this end, this study proposes the Human-Centric.
