ABSTRACT

This research work is concise and generally summarizes the activities duly carried out in the design and implementation of a computerized inventory control system for a manufacturing organization. The system is designed to efficiently handle the movement and tracking of goods through the replacement of human workers by technology. The manual method or intervention is labour intensive, costly, and error prone and cannot ensure the inventory remains up-to-date due to oversight and internal shrinkage. With the proposed new system, inventory can be updated in real time without product movement, scanning, or human involvement. The automated system allows inventory status to be determined and shipping and receiving documents to be generated automatically triggering automatic orders for products that are low in inventory. The study outlines the main concepts of the analysis and design methodology of the proposed system, compares it to the existing and goes further to explain the design and implementation of the system using Visual Basic 6.0 for the database. The fact finding techniques employed is interview, observation, online and library research.

0 INTRODUCTION

An inventory control system contains a list of orders to be filled and then prompts workers to pick the necessary items, and provides them with packaging and shipping information Inventory control may be used to automate sales order fulfilment process and also manage in and outward material of hardware Automation is the replacement of human workers by technology For optimal sales and inventory management process, robust functionality is needed for managing logistics facilities Warehouse management functions for inventory control cover internal warehouse movements and storage and its support helps in the recording and tracking of materials on basis of both quantity and value

This application takes care of all supply orders reducing cost for warehousing, transportation while improving customer service It significantly improves inventory turns, optimizes flow of goods It also improves cash flow, visibility and decision making providing efficient execution of tasks using this fast and reliable computerised method

11 BACKGROUND OF THE STUDY

The Nigerian Breweries PLC was established in the year 1946 It aims at providing satisfaction and nourishment to the Nigerian population through the distribution of drinks like beer, coca-cola, fanta, sprite etc It is second to none and for this reason, the demand is high and the company responds to the increasing demand by stabilizing supply to strike a balance

Justifiably, the company has the problem of keeping adequate record of goods transfer and since it is done manually, associated problems of insecurity, high cost of operation and delay in supply arise Data processing in Nigerian Breweries PLC is presently carried out using people, pens, and paper to control stock and inventory

The design and development of a computerized inventory control system for the Nigerian Breweries PLC will no doubt bring immeasurable relief from the problems associated with the manual system

12 STATEMENT OF THE PROBLEM

The Nigerian Breweries PLC is to an extent manually operated and reveals a number of problems

The recording of sales and cash received are done manually on a book that appears rough Thus, the books are exposed to physical damage, information can be lost and dust particles are accumulated

            The long list of supply orders waiting to be attended to on daily basis

            The control system is time consuming, less accurate and less efficient, and the environment is not user friendly

            Inaccuracies often ensue from human error

The manual system is quite tedious and can be reduced or eliminated with the introduction of the proposed system

13 PURPOSE OF THE STUDY

The purpose of this study is to improve current operational process in the Nigerian Breweries PLC to its full capacity by developing efficient computer software that can handle inventory in a computerised fashion

14 SIGNIFICANCE OF THE STUDY

This study is primarily aimed at increasing efficiency in operations, reducing maintenance and running cost, monitoring the supply of goods and its distribution and increase profit in the Nigerian Breweries PLC by introducing a computerizedinventory control system

15 OBJECTIVES OF THE STUDY

The main objective of this study is to develop a computerised inventory control management system Others include;

i          It provides total asset visibility

ii         It allows reduced inventory stocking levels giving full inventory history

iii        It reduces lead time, shelf space, and errors due to damage, fatigue of staff and overall cost of operations

iv        It facilitates “just in time” deliveries

v         It provides full process control for products

vi        It provides higher level security as the system would be passworded to prevent unauthorised access

vii       It shortens cross docking time and speeds up sort/pick up rate

viii      It helps the management plan, monitor, optimize resources and ascertain their financial position at any time

16 SCOPE OF THE STUDY

The scope of this study covers the Nigerian Breweries PLC as a whole, and its customers which include retailers, distributors and the general public

17 LIMITATIONS OF THE STUDY

This project was constrained by the following factors:

(a)       Financial Constraints

Bearing in mind the economic state of the nation, it was found difficult in making both ends meet, because of the exorbitant nature of things nowadays in travelling for the collection of data needed for the project

(b)       Time Constraints

Looking at the interval between the resumption and vacation of the final semester for the project to be completed, the time given seemed to be short for the collection of required information for better work to be done

(c)       Non-Availability of Material

During this project, it was noticed that the required materials needed for the project are not documented Those that were documented lacked storage facilities where they can be reached
