1. INTRODUCTION
The
advancement of information and communication technology (ICT) in recent years
allowing organizations to perform operations that before were not imaginable
today, there are several examples of companies that use you to obtain cost
reductions to improve of competitive advantage (NAZÁRIO, 2017).
Information and communication systems focused on the area of logistics function as connections linking the logistics activities in an integrated process, combining hardware and software with the goal to measure, track and manage logistical operations, which can occur within a specific company, as well as along the entire supply chain (NAZÁRIO, 2017).
In this context, this research evaluates the use of information and Communication Technology, seeking to answer the following question: An Enterprise Resource Planning system (ERP) combined with mobile technology can raise the level of service of storage operations within an Organization?
To answer the problem of research, part of the following hypotheses:
· The use of ERP system integrated with mobile technology can improve process flow and reduce costs in the storage process
· Changes in processes with this integration will bring greater speed in the process of materials supply the Assembly lines.
Having as main objective to introduce the use of ICT in logistics operations, specifically in the process of storage with the use of an ERP system integrated with mobile technology, showing how knowledge form a case study.
The
company studied that had a major expansion of its activities in the past 5
years with the use of Enterprise Resource Planning system (ERP) based on its
processes. With this expansion, storage processes of materials in processes
became critical, and storage and supply of materials greatly increased, so the
information and communication technology used could be increased with the use
of integrated systems that could allow greater management especially in the
process of storage.
The article is organized into the following sections: Section 2, which features a review of the literature on storage materials and information and communication technologies, applied in logistics operations. In section 3, it is outlined the research method used in development of a case study and in section 4 the case studied is presented and analyzed in section 5, contributing to elucidate the use of ERP integrated mobile technology, finally, conclusions and recommendations for future work are presented in section 6.
2. LITERATURE REVIEW
2.1.
Materials
Storage
To
Ballou (2008), the storage activity is an administration room to keep stocks,
namely, storage is any process that includes stocks in literature there are
some kinds of storage, such as Distribution Center (DC), logistic operators,
cross-docking, transit point, among others. For Carrilo (2017), the primary
storage process is between the receiving and the separation of applications,
for the movement of materials such as need for the process of the entire
organization to function successfully.
This
is necessary so that the stock administration is favorable to the company,
because the thought that stocks is money still goes through organizations
stopped but in fact is an indispensable process for it delivered products with
more agility for customers, or even that the raw material is placed in the
production process faster (CARRILO, 2017).
2.2.
Concepts
Soriano
(2013) States that the storage has been through many transformations in recent
years, and these factors are from the adoption of new information systems,
automatic handling systems and separation of applications, new equipment and
structures of storage.
According
to Soriano (2013), the main purpose is to manage the storage space and time,
this refers to the available space in the warehouse must be used in an
organized manner and rational, as the time available for practice activities
warehouse operating. In addition to the
management of space and time, Ballou (2006) says that the storage of the
products and the handling of materials, are also storage management functions.
2.3.
Classification
For
Ballou (1993), not just the location, but determining the size you need the
building is of paramount importance if used space rented in combination with
space, you need to use the space rented only to meet the needs of peak storage
according to the same author, there are four options for storage, and they are:
·
Have the deposit.
·
Rent physical space.
·
Rent deposit (deposit) and store in each alternative
transit.
·
offers different levels of cost, risk and economic
involvement.
For
Bowersox and Closs (2001), there is a second aspect that involves quantitative
analysis is the study carried out on the products to be distributed by
deposits. Both the project as the operation of deposits will have to be
directly associated with the characteristics of the products.
The products must be analyzed individually in relation to annual sales, demand stability, weight, volume and packing. Must be analyzed in this review the size, volume and weight of the average request to be processed in the warehouse.
2.4.
Storage
Management Activities
Ballou (2006) explains that the two relevant functions of storage are storage and movement of products and are divided follows:
·
Materials
storage.
·
Consolidation to load training.
·
Transshipment
volume fractionation Maintaining.
·
Handling
loading and unloading to stocking.
·
Separation of applications.
For
Soriano (2013) there is no unanimity in relation to descriptions of the
activities related to storage management.
2.5.
Information
and Communication Technology
According
to Jamil and Silva (2014), ICT's are part of a new concept of organizational
context, which the authors define as "the set of procedures, methods,
systems and relationships (of order management and/or technological) that guide
the organizational actions both in regulatory aspects, and in the productive
coexistence of its components" (JAMIL; SILVA, 2014, p 23).
In this new context, ICT's are analyzed in two dimensions: infrastructure and content. The content is related to management of information/knowledge that will be combined with the managers for effective decision-making. To Pinho, Nogueira and Franco (2014), as organizations need to be agile in your decision-making to adapt more quickly to changes of market, technology is essential to achieve this goal, allowing greater interactivity and flexibility the adoption of systems of information and communication technologies (ICTs) makes it possible to transform the existing business model.
According to Pinho, Nogueira and Franco (2014), ICT's are considered the main impetus of growth in the knowledge economy, however, it is important to note that communications technologies, especially, have been growing and causing the initial concept of ICT is revised. With the growing importance of information that takes organizations, whether public or private, to focus on modernization and technological sophistication.
2.6.
Software
Used
2.6.1. Warehouse Management System (WMS)
Warehouse Management System (WMS) is basically a management system that streamlines the operations of a warehouse through the efficient processing of information with high accuracy of inventory and information activities occur in receiving, in the storage, in the separation, on the production line and in the expedition, using this information to manage more efficiently the processes (BANZATO, 1998).
For Barros (2017), the benefits generated by the WMS are numerous due the main points, as for example, optimizing storage space, reducing waiting time, optimizing the routing of the separation of applications, online availability of real quantity in stock, among other benefits. All these benefits bring significant improvements to the organizations, such as cost reduction, improving customer service, reducing overtime, additional manpower and decrease errors, because the system streamlines the information flow optimizing logistics processes (BANZATO, 1998).
2.6.2. Mobile
Technology
known as TIMS (Mobile Information technologies and wireless) this technology points to a big improvement in the processes, reflecting on gains in efficiency, speed of information, better planning and with the reduction of errors (SACCOL, MANICA; CALDERWOOD, 2011).
Some studies cite four fundamental entities for mobile technology; The environment, which involves the motivation of employees in the Organization; The user, which is labor who will operate the system; the device, which consists of the hardware, which can be anything from a computer to a touch screen for the manipulation of data, and; The software, which is the programming of data processing, including an internet service provider (CORTEZIA; COLUMBO, 2014).
Mobility here refers to a mobile device, without cabling that processes information with agility. Usually smartphones and tablets because they are more popular in the everyday life of the people and the ease of creating applications on these operating systems (CORTEZIA; COLUMBO, 2014)
In accordance with the current technological trend mobile devices like smartphones and tablets have been considered in the context of companies, these devices enable the development of applications that integrate with ERP and thus function as a mobile interface that can be used in the improvement of processes (SZYMCZAK, 2013).
2.6.3. Enterprise
Resource Planning (ERP)
For Rosini and Palmisano (2012), at first, an ERP system (Enterprise Resource Planning) is the evolution of MRP (Materials Resource Planning), an integrated system of production, the goal of ERP is to achieve the integration of all systems of the Organization, employing what is known for best practices, i.e. the best management practices of existing businesses.
According to Monteiro (2016), in the 90 arises the term Enterprise Resource Planning (ERP) by consultant Gartner Group. In order to integrate various areas of business of an enterprise, increasing information-sharing throughout the enterprise, centering only in a database.
With technological developments adding various types of technology, the reduction of complexity, or the ease of dealing with data is the main reason for the ERP implementation in an organization beyond the enterprise ERP improvements therefore brings a better customer support and management of the relationship with suppliers (HASSABELNABY; HWANG; VONDEREMBSE, 2012).
Currently we meet in the ERP/generation III where increasingly the ERP has become an open system that offers Web-Based Tools, integration with social networks and mobile devices such as smartphones and tablets (ROMERO; VERNADAT, 2015)
2.6.4. Radio
Frequency Identification (RFID)
According
Zhu, Mukhopadhyay, and Kurata (2012), RFID (Radio Frequency Identification) is
supported by a tag and an RFID reader, interconnected by a software for reading
and processing the data label has a small microchip that stores and transmits
information in real time through antennae that emit and receive the data via
radio ondar.
To
Duroc and Kaddour (2012), this technology is a wireless network that uses radio
frequency waves to communicate with the tags that have microchips containing
the required information for each product in this way the RFID can have two
types of use, and tracking of objects, requiring only the tags, antennae and a
software (SUN, 2012).
3. METHODOLOGY
The
present study this is an exploratory research which has been prepared in the
form of a case study, qualitative analysis of data collected in the company
according to Gil (2002) exploratory research aims to create greater familiarity
with the problem exposed, making more explicit or constitute hypotheses
represented by a case study.
Defined
by Yin (2001) as a search strategy that comprises a method that covers
everything in specific approaches to data analysis and opted for conducting the
study on the company in question, due to ease of access to data and information
for research.
The
study was conducted in a manner following an order of methodological study,
first with the bibliographic survey about the topic to research in books,
Capes, and Scielo site on the subject of information and communication
technology used in logistics operations of storage in a company.
The
next step focuses on collecting data needed to analyze what was operation prior
to deployment of mobile technology and highlight what improvements the storage
and supply activities of assembly lines would suffer after integration of
systems and the results achieved by the company.
In
this stage were carried out interviews with managers and employees involved in
the deployment of mobile technology, where they spent all the steps performed
and we were shown, as was the operation before this new model. We can verify
that there were noticeable and relevant improvements in processes, the company
provided documents with data proving this improvement obtained.
4. CASE STUDY
4.1.
Company
Characterization
The company researched develops and produces toys, children's products use bikes for education, sport, leisure, playground and childcare, since 1952, located in São Paulo, the company is large and today occupies the position of leading toy makers from South America.
Because your expansion and acquisition of new equipment, the stock in the warehouse of materials in processes also grew up getting overwhelmed when it comes to storage of these materials. From then on the length of time in storage and supply of materials has increased considerably, and so many materials began to be lost in stock, because there was no effective controls at the warehouse.
4.2.
Data
Collect
At
the warehouse of material components in the process are stored all the
semi-finished products (components of toys) from materials of metallurgical
processes, painted, injected, blown, among others. That supply the Assembly
lines, approximately 2 500 different items are stored in this warehouse that
has an area of 30.097.50 M3 in the image below you can see the placement of the
warehouse about other areas.

The
supply process of the assembly lines was executed according to the flow of
activities below and even using the ERP system the process was time-consuming
and took on average 4 hours at 3 hours and 30 minutes.

In
addition to a complex process, it was necessary a large team involved in 3
shifts, totaling 28 employees in the various activity performed by the
warehouse according to the table below.

According
to the Supervisor of the logistics, this process presented not only a as also
great occurrence of mistakes. Many times, employees did not know where the
material was stored or even couldn't find the components in stock, since the
materials were stored at random, all this takes lead a series of impacts on
integrated processes to the warehouse, and the main one was the line stop
caused by the storage of components, shown in chart for the year 2015.

Analysis
Of The Use Of Mobile Technology
To improve the storage and supply activities of the Assembly lines was proposed the use of information and communication technology; however, as the company already had an ERP system implemented and structured idea was using a technology that was easily integrated to the ERP system.
In a
basic comparison between literature and the application in the Organization the
solution presented greater relationship with the concepts of integration with
ERP and low cost of implementation, was the use of mobile device.
For Monteiro and Costa (2016), mobile technology has easy integration with the ERP system of the Organization, increased mobility, low cost of implementation, the devices used are already part of everyday life of employees and streamlines and simplifies the process. In this context the was mobile technology, with the creation of a mobile application developed internally and especially to the activities of the warehouse.
4.4.
Stock
For Addressing
That
implemented the mobile technology integrated with the ERP system were required
some adjustments as the addressing of the stock that was not used. This adequacy did not require large financial
investments, the warehouse was divided into streets and blocks, being
identified with metal plates inscribed with the letter for the address and the
blocks of each position were painted on the ground, as shown in Figure 02 After
created, these addresses were registered in the ERP system.

Identification
of materials
For
mobile technology was used to facilitate the storage and supply activities of
the Assembly lines was necessary the adequacy of identification labels, i.e.
the tags until then used were replaced by new labels that bring with them the
barcode thus enabling reading and interaction with mobile technology.

4.6.
Infrastructure
The
largest investment for the system developed to work properly was on
infrastructure, because it required the acquisition of mobile devices
"phones" with Android system and rear camera. So that the readings of
the labels could be carried out, as well as the installation of Wi-Fi antennas
at strategic points of the warehouse, where the devices could connect and
access the same database.

5. RESULTS AND DISCUSSIONS
With
the use of mobile technology integrated with the ERP system there have been
significant changes in the process of storage materials the first was that the
storage of materials before made at random, from the deployment of technology
Mobile began to be stored and addressed soon after leaving manufacturing
machines.
When
the truck pulls out the components of the production processes, storage is done
using the mobile device through the reading of the ID tag where the application
automatically provides the information of available addresses. When choosing
the addressing, the material is addressed can be consulted on the fly without
the need to go to a computer terminal, as the image below.
Figure
5: stages of use of the application to addressing

The
second change was in the process of supplying the Assembly lines where there
was an extremely lengthy and bureaucratic process, and with the use of mobile
technology integrated with the ERP system. The process has been simplified and
now requests are sent automatically by the ERP system to the mobile phones
according to the need, in other words, all request generation process and
Conference were eliminated.
As
for the separation of materials, employees do not waste time to find the
materials inside the warehouse since to choose the components to be delivered
by mobile application the system will find all the locations that component
within the warehouse always in order of the oldest, as the stream FIFO rule.
Below
you can see the before and after of the supply process of assembly lines it
took on average 4 to 3:30, with the mobile system integration with ERP system,
was reduced to an average of 2 hours.

With
the Elimination of certain activities within and outside the warehouse was
possible 28,6% reduction in staff involved in this activity an R$ 29.475,44
reduction/month, being allocated to other areas such as dispatch of finished
products.

With
the optimization of the supply process activities of materials occurred 63%
reduction of parts mounting losses and 62% in relation to the % line stop
caused by components stores compared with the previous year, according to the
table below.

6. FINAL CONSIDERATIONS
The
results obtained with this survey attended the objective sought, it was
possible to present the use of ICT in logistics operations, specifically in the
process of storage with the use of an ERP system integrated with mobile
technology.
The
assumptions have been confirmed, with respect to hypothesis 1, it can be shown
that the use of the mobile system integrated with ERP in company object of
study, made possible cost reductions, as the 28,6% reduction in headcount and
reducing the occurrences lines stops by failures of the storage area, in
addition to the improvement in process flow.
Observed
through the figure 6 and the survey data and interviews with employees. With
respect to hypothesis 2 the same way it was possible to confirm that the use of
this system allowed the simplification and speed the process of supply of
material for the Assembly line. Proven by the analysis of the data of the Assembly
line that previously took an average of 4 to 3:30, and the mobile system
integration with the ERP system, was reduced to an average of 2 hours.
Through
the data it was possible to identify that really the integration with the ERP
system was easy and along with that There was a low-cost implementation, which
goes against the observed in the literature. The main perceived limitation in
this survey refers to the impossibility of generalizing the findings, because
in this case study was proven improvements in processes with the use of the
mobile system integrated with ERP, however it is worth noting that despite the
activities carried out have brought great benefit, other companies in the same
or in other sectors may or may not benefit from the same strategy parsed.
As
recommendations for continued research, it is suggested, the evaluation of the
use of RFID in the logistics operations of company studied.
