DESIGN AND IMPLEMENTATION OF A COMPUTER  BASED SEAPORT BILLING SYSTEM  (A CASE STUDY OF NIGERIAN PORT AUTHORITY LAGOS)

ABSTRACT

Handling of Cargo has been a circular task all these while in our various ports. And Nigerian Ports Authority (N.P.A) being an organization responsible of seeing to the affairs of our various sea ports in Nigeria, have worked endlessly to make sure cargoes are properly handled without much complain of damage or misplacement.

To ease the operation of Cargo handling in our sea ports, research took up this study by critically understanding the work, procedure involved, analyzed of the various steps and at the same time detecting problem in the present system and designing a new system that has solution to the problem of the existing system.

The new design is computerized and is subject to modification at any given time. It also have this interaction feature and accurate in it’s output.

 

ORGANISATION OF THE WORK

          This work is organized in seven chapters and appendixes as follows:

          Chapter one: deals with the introduction of Cargo handling, statement of the problem, aims/objectives, purpose of study, importance of study, definition of terms, assumptions.

          Chapter Two: Gives review of related literature, researched.

          Chapter Three: Method of data collection, organization structures, objectives of existing system, input process, output analysis, information flow diagram, problem of existing system, justification of the new system.

          Chapter four: Output specification and design, input specification design, file design system flow chart, system requirement.

          Chapter five: implementation, program design, flowchart, pseudo code, source program, test run.

          Chapter six: Documentation, choice of range, loading the design, program description.

          Chapter seven: Conclusion, recommendation and references.

 

CHAPTER ONE

1. INTRODUCTION

Nigeria Port Authority is a government owned organization under the supervision of the federal ministry of transport with responsibility of providing specific ports and labour services for the country’s meantime industry.

One of their numerous duties and major functions is the provision of Cargo Handling quays facilities. Right from the inception of this company, the billing system has been manually processed. The port complex is in the early stage of computerization and the manual method of preparing customer’s bills are delayed.

A computer – based billing system is necessary for handling and preparing of accurate bills for customers. The new system will facilitate the prompt preparation of bills, easy retrieval of information, security to vital information and resource charring among the billing department.

1.1    STATEMENT OF PROBLEM

          History has it that the billing system in Nigeria Port Authority, one port has been plagues by several factors based on the current manual process by the use of the Draft import Debit and import Debit note, these factors includes:

1. Fills and records are not properly kept
2. Errors are easily made and hardly detected
3. A lot of time is wasted to prepare bills
4. Information is not well documented
5. Security of files or document is not granted

AIMS AND OBJECTIVES

The primary aim of this project research is to develop a computer based seaport billing system that will handle the bills raised for various customers specifically in NPA, onne Port. A computer based system can be batched or interactive.

A batch processing system is one where transactions are accumulated into batches of suitable sizes, then each batch is sorted and processed as a simple unit. Batch processing has a degree of delay. Interactive system are those which allow the user to input data in response to the information displayed on the screen.

This project s concerned with only ever, the researcher touched all parts of system design that will enhance a computer based billing system in NPA.

 

PURPOSE OF THE STUDY

The main aim of this study is to computerize Nigeria Ports Authority, one port billing system in order to improve their transaction rate of services to their various customers.

 

SIGNIFICANT OF THE STUDY

The need for a study of this nature can not be over emphasized. It is expected that will the designed system, one can realize some important effects of the computerized billing system. Some of the effect are:-

• The chances of frauds of any kind will be drastically reduced as well as errors on customer’s bill.
• The new system saves time and facilitates the prompt raising of bills as delay brings on extra cost to customers.
• The information flow is well maintained and it enhances the top management decision making.
• The new system ensures ease of processing and hence ensures faster processing of output on customers waiting to collect personal property as the container of goods.

1. Consignment: The same as the container of goods.
2. Consignee: The same as importer of the container.
3. Groupage: When two or more importers come together to improve one or more containers.
4. Harbour: This is a safe lace where ships can be to load or unload.
5. Hardware: Is all the physical devices around the computer.
6. Interactive processing: A process where by the users communicates directly with the computer.
7. Port: It means the commercial area of the harbor at the part of the harbor used for loading and in loading of goods.
8. Quats: A stone or metal plate form in a harbor where boats / ships come in to load.
9. Soft ware: All the programs in the computer.
10. System: This is a set of interrelated elements working together to form a unit to get some output.
11. System flowchart: This is a diagrammatic representation of logical flow of development of system through different stages or processes around the computer and its various task.
12. Tariff: Tax on a particular class of imported goods.
13. Transfer charge: The money paid for the services rendered by N.P.A in transferring the consignment from the ship to the port.
14. VAT: Value Added Tax – tax on the value of a product at each stage of manufacture and marketing.

 

SCOPE OF STUDY

The scope of the study basically covered the area of information exchange as well as information generation.

It also covered data security and authenticity as well as reportage. These areas were identified and grouped into:

1. Data capturing
2. Information processing, and
3. Reporting

 

LIMITATION OF STUDY

During the course of this project work, the researcher batted with time and money constraint which nearly affected the progress of the work. Despite all odds, the researcher was able to produce a defendable work.

 

ASSUMPTIONS OF STUDY

Sequels to insufficient information, the following assumption were made:

Most researchers are not computer literate as a result, are not aware of the importance of computers to their research work or research process so they are totally ignorant of it. They can actually afford an internet ready personnel computer, and the general public is computer enthusiasts.
