Design And Implementation Of A Bill Of Materials Processing System


With the trend of technology growth in the world of today, virtually every facet of human work has been affected; even the remotest of it all, and the production circle cannot be left out. This study was carried out to verify all the manual processes involved in bill-of-material processing system and to seek a way of automating the system for effective operations.

Since there is continuous moves towards technological advances that enhanced productivity of labour and free human beings of tasks done more economically by machines. Computer and its applications have become indispensable and vital tools in economic, industrial and social development of the advanced countries of the world. Nigeria as a developing country cannot afford to lag too far behind in this kind of revolution. Therefore there is every need to know in every discipline the areas, which attracts computerization and why they need it.

In this project, the software engineering principles were applied in the analysis, coding and testing of the software developed for the Bill-of-material processing. Serious attention was also give to the design of the user interface.

In the development of the software, visual basic programming language was used de to its support for all the features desired. A brief user’s guide is also provided. The end result is a software that is very effective and efficient in meeting it objectives and at the same time user friendly.

Chapter One


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.

  1. Reliability
  2. Validity
  3. Accuracy
  4. Appropriate storage of data
  5. Timeliness

The above factors are due to the fact that the computer possesses some great features, and advantages over traditional approach.

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.

  1. Poor information storage method: The use of office files and file cabinets is not a good form of information storage.
  2. Insecurity of data because it is prone to vandalization and unauthroised accessibility
  3. 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-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-of-materials 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 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:

  1. The recording of Bills-of-materials has not been made
  2. Hardware for the installation of the program or software is procured already
  3. 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.

(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.

At this juncture, one will like to say that the program or software is completely produce and it satisfies the requirements to overcome the deficiencies of the existing system under study. thus, it is now my desire to call for the implementation of this system to assist EMENITE and other manufacturing/production companies (that may deem it important) to embrace this software fore liability and validity of the output.

As the researcher and implementers of this software, hereby recommend that the entire requirement stated above must be available to ensure effective and efficient usage of the software. Also, I recommend that the organization should provide an opportunity for workshop/seminar to educate the operator. More so, he program is not restricted from further modification, but changes could be made as soon as additional information is discovered which would pay the organization effectively. But for any modification I strictly recommend the programs to study carefully the program documentation. I therefore at this juncture welcome all scholars; students who would like to explore more on this topic (Bill of material processing system) for further research on the broad subject probing into the areas that I could not investigate on. I would be very happy to see to it that this work is further improved in virtually all facets, because of the dynamic nature of the field as regards computer studies. However, I also recommend uses to follow the appropriate instruments during the use of this software. Above all this project work contains analysis of the existing system (traditional system) and computerized version of the tasks performed, which were made to survive the loopholes of the manual approach equally, seeing the justification of this computerized system its validity, reliability and efficiency, I hereby recommend parallel change over system – using the system simultaneously with the existing system, till it is successfully but gradually eliminated (Traditional system) and the new system fully implemented. This is to further appreciate the new system and its advantage over the manual system.


The introduction of computerized system in any organization is advantageous and encouraged to be adopted. As a researcher, one will only site the advantages only but also the demerits, such as; employment of expertise equally, seeing the justification of computerized system, its validity, reliability and efficiency; I will conclude that EMENITE and every other production company should deem it necessary to have this software or any other related software written by an expert and for Bill of processing to enhance their production capability.
