This dissertation was written as part of the MSc in Mobile & Web Computing at the
International Hellenic University.
The commercial sector is undoubtedly one of the greatest in the economies of all
countries and so retailers strive to increase their profits daily by attracting more
customers and more sales. Their main problem is when they get out-of-stock on
products that attract these customers, ending up losing them and thus losing their
profits. That being said, one can clearly understand that the re-supply process of a
retailer plays a crucial role to the wellbeing of the business and sticking to traditional
ways, away from information technology, leads to an even worse situation. IoT
(Internet of Things) devices and technologies should be used to transform the
aforementioned process into a simple and easy task and minimize the stock-out
problem that retailers have to deal with.
In this dissertation, an IoT system is proposed to help retailers to confront this problem
and limit its consequences as much as possible. The system has two parts, the vendor
system which, as the name implies, is used by vendors who provide supplies and the
retailer system that is used by the retailers. These two IoT systems communicate with
each other through the internet and provide a retailer with the ability to re-supply
from all its vendors at once without having to organize which products should be send
to which vendor through his order. Furthermore, the option to place again a previous
order is given, allowing the retailer to re-supply the next time even faster, since they
tend to order the same supplies.
