Apstrakt:
Termin Industrija 4.0 (I4.0) označava transformaciju globalne privrede pod
uticajem tehnoloških dostignuća XXI veka. U okviru ove disertacije analizirane su
mogućnosti primene tehnoloških pilara I4.0 za rešavanje reprezentativnih
problema (model zona) u LEAN industrijskim sistemima. U prvoj studiji predložen
je okvir za upravljanje nebezbednim uslovima i nebezbednim postupcima primenom
mobilnih i internet tehnologija. Takođe, izvršena je analiza zahteva i predloženo je
rešenje prilagođeno za mala i srednja preduzeća. U drugoj studiji slučaja predloženo
je rešenje za unapređenje dimenzione kontrole ekstrudovanih gumenih profila.
Rešenje je bazirano na upotrebi digitalne kamere i algoritama kompjuterske
geometrije i obrade slika – čime je postignuto je poboljšanje performansi operatera
od ~6%. U trećoj studiji slučaja predložen je sistem za popis materijala koji se
transportuju na paletama u štamparskoj industriji. Digitalizovani popis pokazao se
kao neupo...redivo brži i pouzdaniji od trenutnog-ručnog popisa skladišta. U četvrtoj
studiji slučaja predloženo je rešenje za analizu neergonomskog transporta tereta
ručnim kolicima. Upotrebom IoT modula detektuju se povećane vrednosti sile kojom
radnik deluje, što omogućava analizu odgovarajućih frejmova snimljenih internet
kamerom. Identifikacijom kritičnih momenata, u kojima algoritmi dubokog učenja
omogućavaju trodimenzionalni prikaz položaja tela operatera, omogućena je
preciznija analiza ergonomskih rizika. Validacija predloženih algoritama i
rešenja ukazuje na veliki potencijal za njihovu širu praktičnu primenu. Zaključeno
je da postoji veliki broj specifičnih problema u industriji koji zahtevaju namenska
rešenja – što otvara velike mogućnosti za dalja istraživanja i razvoj
digitalizovanih rešenja baziranih na pilarima I4.0.
Abstract:
The term Industry 4.0 (I4.0) refers to the transformation of the global economy under the
technological advances of XXI century. The aim of this dissertation was to assess possibilities
for applying I4.0 technological pillars for solving various representative problems (model
zones) of LEAN industrial systems. In the first case study, a framework for managing unsafe
conditions and unsafe acts by using mobile and internet technologies was proposed.
Moreover, an analysis of requirements and аdaptation of the proposed solution for use in
small and medium enterprises was performed. In the second case study, a solution for the
dimensional inspection of extruded rubber profiles was proposed. The solution is based on the
use of a digital camera and algorithms for computational geometry and image processing –
which improved operators’ performances by ~ 6%. In the third case study, the system for the
inventory of materials that are transported on pallets in the pri...nting industry was proposed.
The digitized inventory has shown as significantly faster and robust compared to the currentmanual inventory practice. In the fourth case study, a solution for the detection and analysis of
non-ergonomic cargo transport by handcart was proposed. By using an IoT module, increased
values of the force exerted by the worker were detected, which enabled the analysis of
corresponding frames acquired by the IP camera. Identification of critical moments, by using
Deep learning algorithms for three-dimensional assessment of the operator's body pose,
enables a more precise analysis of ergonomic risks. Validation of developed algorithms and
solutions indicated a high potential for wider applications. It was concluded that there are a
number of specific problems in the industry that require dedicated solutions - which opens up
opportunities for further research and development of digitalized solutions based on the I4.0
pillars.
