CHAPTER ONE
INTRODUCTION
1.1
BACKGROUND OF THE STUDY
The use of traditional approach in problems solving has really
left some loopholes in life and this has encourage the introduction of
computers in various fields of work including production in terms of
keeping of bill of materials in production and most recently
reordering of sales.
The Bill-of-material processing system has been in existence
in many organizations though in a traditional approach. Introducing
the computer system will greatly improve materials requirement
planning in the following aspects.
(a) Reliability
(b) Validity
(c) Accuracy
(d) Appropriate storage of data
(e) Timeliness
The above factors are due to the fact that the computer
possesses some great features, and advantages over traditional
approach.
7
1.2
STATEMENT OF THE PROBLEMS
No doubt that the use of traditional system has created a lot of
problems in production of roofing sheets at EMENITE. The quantity
and amount of materials and sub-assembly needed to produce a
product cannot be traceable because of glaring disadvantages stated
below.
 Poor information storage method: The use of office files and
file cabinets is not a good form of information storage.
 Insecurity of data because it is prone to vandalization and
unauthroised accessibility
 Duplication of data in various departments because of the
nature of work needed
It takes a long time in accessing records in the manual system
(filing system) due to the nature of the job. It is not always good for
materials to finish unnoticed, so the re-ordering of materials are not
made as and when due.
The introduction of the computer system will help eliminate these
problems to an extent.
1.3
PURPOSE OF THE STUDY
This project is generally towards eradication of all the
deformities and curb hookups of the manual method of bill-of-
8
materials processing, thus developing a new system to handle the
jobs involved in the processing of Bill-of-material electronically.
1.4
AIMS AND OBJECTIVES
In
an
organization
whether
manufacturing
or
not
manufacturing where the competitors and the objectives of the
organization are at the top of the scale of preference especially the
meeting of the standard in the market, there is always a focus on the
organizational goal which might not be the goals of the sub-system
to avoid sub-optimality, working towards a divisional or individual
benefits.
The aims of this work include the following;
(1) To work towards the elimination of ineffective modes of
operation; it centers on the user having a good atmosphere for
work thereby minimizing stress.
(2) The objective from the initiator of the proposal is generally
towards combating al the aims and the problems being
discovered on the existing system, which are listed under
problem of study.
(3) Safeguarding of information through effective monitoring of
access is the filing system (database).
(4) Knowing when materials are almost out of stock, in order to
make an order so as not to show the production pace of the
labourers.

1.5
SCOPE OF STUDY
The scope of this project work covers all the areas of bill-ofmaterials processing systems, which include the cost of individual
material responsible for production, the stock control or inventory
areas, and every other necessary areas. The storage of records,
which have different fields that could be expanded a little to form
files. These file five rooms for editing, updating and retrieval of
information when needed. Some of these fields are item description,
quality, total requirement, re-ordering point, labour cost, overhead
cost, profit, lower cost, etc.
This project is focused on the entire information recorded on
Bill-of-material processing for EMENITE NIGERIA LIMITED,
EMENE, ENUGU STATE.
1.6
LIMITATIONS
The constraints that were highly against this study are as
follows:
(1) Time Lag: the fact that the duration of the project work was little;
the researcher would only cover little scope. The time for the
researcher to combine academic works and project writing is also
another limiting factor.
(2) Financial constraints: The researcher’s low financial backbone
really affected the project writing. This stopped the researcher
10
from traveling wide to industrialized areas like Lagos so as to
meet with bigger companies instead of EMENITE.
1.7
ASSUMPTIONS
Sequel to insufficient information, the following assumptions
were made:
 The recording of Bills-of-materials has not been made
 Hardware for the installation of the program or software is
procured already
 The people to use the systems are in the industry already.
1.8
DEFINITION OF TERMS
(1) Traditional Approach: The system of use of files, file jackets and
file cabinets in the storage of records i.e. the manual way of
storage of information.
(2) Record: Facts of a particular material and any other thing used in
production.
(3) Field: An item of data within a record. It is made up of a number
f character.
(4) Hardware: The physical component of a computer system e.g.
keyboard.
11
(5) Software: The program in the hardware of the computer that
instructs the system on steps to take in executing a giving task.
(6) File organization: The process or the way of arranging and
maintaining files that are used for keeping of records.
(7) Flowchart: This is a diagrammatical representation of procedures
taken in executing a given task.
