ABSTRACT – Keeping accurate material inventory is
critical to ensure smooth operational activity. The
academic laboratory was facing issues with inaccurate
inventory record. This study is about designing an
electronic inventory control mobile application to
manage the inventory and improve the stock record
accuracy. The mobile application was developed using
the Android system and is called E-Inventory. The
mobile E-Inventory application was successfully tested
by the academic staffs and engineering assistants. The
E-inventory has proven able to reduce the time to access
inventory by 80% and to accurate track inventory
compared to manual stock count.
1. INTRODUCTION
Inventory control is very important to an
organization because all the stock must be managed,
controlled and tracked at anytime and anywhere.
Nowadays, inventory control is even more crucial to
success and sustainability. Inaccurate inventory control
can lead to lost business profits. Chuang and Oliva [1]
claimed that IRI (Inventory record inaccuracy) reduces
a company’s total profits through a study on a retail
store which has an IRI of 29% causing the company
losing 10% profits. Manually managing the stock may
be inaccurate, consume time and also prone to human
error. Among the factors causing the inventory record
inaccuracy; (i) missing main sources of stock, (ii)
misplacement of stock and (iii) stock transaction errors
[2].
To solve these issues, inventory control requires a
computerized system to better manage the inventory [3].
With the increased amount of material variations and
quantity, manually tracking and counting inventory is
nearly impossible. Hence, there are many types of
inventory computer software available in the market.
However, relying on inventory control and tracking
methods solely on a desktop computer is no longer
feasible. In 2017, there are almost 20 million smart
phone uses in Malaysia [4]. Thus, there is a vast
opportunity to develop application software using smart
phones for user convenience.
There are 101 laboratories in the Faculty of
Engineering Technology, Universiti Teknikal Malaysia
Melaka. These laboratories require various consumables
materials for the laboratory activities. The record
keeping and retrieving were done manually using a
yellow form and an Excel spreadsheet. The location of
the various stores also added to the issue of sharing
information between the departments and tracking
similar inventories. These consumable goods need
proper management in order to ensure that the students’
learning process runs smoothly at all times but still
keeping the costs of keeping the inventory at a
minimum. Thus, the aim of this study is to develop a
system to accurately manage these consumable goods in
storage. The use of the E-Inventory system has helped
to improve the efficiency of the laboratory consumables
materials management.
2. METHODOLOGY
The project methodology employed in this study is
using the System Development Life Cycle (SDLC) [5].
The SDLC consists of project planning, system analysis,
design, testing and Implementation.
3. RESULTS AND DISCUSSION
3.1 Project planning
In the project planning stage, the scope of work is set to
focus on solving inventory management issue of the
manufacturing department consumables store. Through
literature reviews, relevant information on inventory
management and latest technology on mobile
application was analysed. Among the free applications
evaluated from the Amazon Application Store include
Instant Inventory, Barcodery, Smart Inventory [6].
3.2 System analysis
In this phase, the issues at the consumable stores
were analysed. Interviews were conducted with the store
manager, lecturers and engineering assistants to map the
current inventory management process. Among the
information gathered from the interview session were
methods to receiving stock, withdrawing stock,
replenishing stock, counting stock and requesting new
stock.
3.3 System design
The software, hardware and network requirement
for the E-Inventory were identified at this phase.
Decisions were made to use (i) Fireball cloud database
to store and manage the inventory data and (ii) Android
