• Introduction
• SMALL Factory Project
– The implemented system
– Dealt issues
• The product
• Teaching approach
– PLM
– ERP
• Conclusions and future developments
Introduction
3
The most industrialized countries are funding national and international programs to promote the integration of the Industry 4.0 enabling technologies within the manufacturing environments.
Introduction
4
The lack of skilled engineers is already restraining companies
from generating more business.
The Smart Factories spread will significantly affect job definition in industry.
Education programs must be updated.
Introduction
5
In the last years, several universities around the world implemented Learning Factories.
Smart Lean Learning Factory
6
The aim of this project is to reproduce a smart factory for educationalpurposes in a laboratory environment, in terms of both hardware andsoftware.
This environment will allow students to become familiar withproduction applications commonly found in the modern facilities and toexperience realistic situations, as required by the “Gemba walk”.

The product
8
Family of trolleys for sliding doors.
Product variants:– Load
– Number of wheels
– Wheels diameter
– Distance wheel to wheel
– Length
– Thread
PLM teaching approach
9
• The PLM teaching approach is based on team collaboration during product development.
• The PLM strategy is composed by three stages of the product lifecycle
Product design
10
• Students are divided in teams (6-8 people)
• Each team is provided with a set of requirements– Wheels are well defined
– Freedom to operate for the main threaded pin
• Design steps– Requirements
– Concept
– Preliminary layout
– Definitive layout
– Product documentation
• PDM systems: Teamcenter, Aras Innovator
• CAD system: Nx
Digital Mock-up

Process design
11
Two steps
1. Part production
• Complete operation sequence
• Necessary resources (tools, machines, fixtures)
• Validation through CAM simulation
2. Assembly sequence
Virtual factory simulation
12
The assembly sequence previously defined is simulated in a virtualenvironment:
• To verify the feasibility of the assembly process
• To validate the sequencing of product assembly
• To evaluate process performance (cycle time, work in process,criticalities)
• To evaluate operators’ ergonomics
ERP teaching approach
13
• Students are divided in teams (6-8 people)
• Each team simulates a company– Team leader
– Warehouse manager
– Planning manager
– Manufacturing manager
– Purchase manager
– Sales manager
– Marketing manager
• ERP system: Odoo, client-server installation
ERP teaching approach
14
• Course structured in two parts– Software tutorial [12 hours]
– Company simulation [12 hours]
• Each team has to satisfy customers’ orders within the due dates– Plan manufacturing activities
– Plan supplies
– Plan deliveries of finite products
– Evaluate company profitability
Conclusions
15
• Students have been provided with satisfaction questionnaires– High overall satisfaction
– Possibility to work in teams is appreciated
– Learning-by-doing approach is appreciated
• Companies will have employees already familiar with IT tools– Reduced startup period
• Mindset growth for students– Flaws in their education are recovered
– Tasks that are not motivating are identified
