ABSTRACT

Advancement of technology has influence the development in various fields including

booking system. For rental cars, it’s difficult to find application that provide the booking service.

Usually car rental owner not advertise their cars on internet but instead they only advertise it

among the resident. Problems occur when customer found that it is rarely application for car

renting. Renting a car through online and mobile is a need among people who does not have

their own transport especially students who needs to move around to do their business outside

campus. Usually they had to ask local for any available car to rent nearby and this manual

way consume a lot of time since current trend where everything available online. To solve this

problem, a platform is needed that can help both owner and rental person in this car rental

system. The owner can promote their car and help boost their advertising in this system. While

customer can search for any cars available for rent without having waste their time. The

expected result of this project are user can easily find a car that available in the system and

the management process of rental cars can be easier and efficiency. By using the Technique

for Order Preference by Similarity to an Ideal Solution (TOPSIS), this system can help user to

make decision based on criteria that has been set and it will show the result.

CHAPTER 1

INTRODUCTION

1.1 Background

Car rental is a company which rent for a short period of time for a fee to their customer.

In Malaysia, car rental service increasingly becomes the preferred option for most people,

especially among students in campuses and universities. This because not all students can

afford having their own vehicle. Some car rental owner still use a manual system to manage

rental car operations by spreading of their available car to local resident. This method wasting

money and time for both rental person and car rental owner. Therefore, it is proposed to have

a system that can be used to provide booking and management to make easier for both of

them The system will help them by find the car rental base on the criteria that user given using

Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method.

2

1.2 Problem Statement

There are car owner may not be able to reply the message from the customer as soon

as possible and this situation can make their customer to find another rental car. Sometimes,

customer want choose which car is the best for them and car owner needs to serve them and

can cause the car owner to take a long time to reply to other customer messages. Besides

that, manual system does not allow user to booking online and hard to keep track on the record

of rental cars. User must contact a car rental owner and wait confirmation about contract out

for a vehicle and this will delay the process of renting car. This method consume time for

tenant and car rental owner.

3

1.3 Objective

The main objective of this project is to develop a system that allow the car rental owner

to advertise their cars and allow user to search any type of car in this system . In order to

achieve the above mentioned aim, below is the objectives of this project.

• To propose a system to manage the car rental business

• To apply technique for user’s criteria preference

• To test of system functionality of the proposed technique such as Software

Requirement specification.

1.4.2 Owner

• Register and login profile

• Add, update, and delete car details

• Approve booking status

1.4.3 User

• Register and login profile

• Can search detail car

• Make a booking

5

1.5 Limitation of Work

There are several of limitation on this system. The limitatian and problem for this system is

there are using internet connection if they want to make a booking car on this system , without

internet connection this system cannot be use.

LITERATURE REVIEW

2.1 Introduction

This chapter provide the literature review that is related with system that will be developed.

The review on that system must be described, evaluated and clarified. In this literature review,

this project will be discuss and revie about the method into a multiple criteria decision and the

implementation of TOPSIS that will be use in that system. This literature review can be a

guideline to develop that system. The source area referring from the book, articles, journals

and also sources from the internet.

2.2 Research on existing system

2.2.1 economycarentals.com

This website (www.economycarrentals.com) is used to ensure the customer can access to

worldwide car hire services at the lowest prices. Customer can search what type car they want

and must pickup point based on placed that car owned choose. Customer need input date

rental start and rental end in this system. Customer also can return car at another place in our

country but must inform where place that customer want to return on this website. Provide the

service that car can be return in different place from pickup point. Figured 2.1 shows the

interface of economycarrentals.com system.

Figure 2.1:Interface of economycarrentals.com

2.2.1 Rentalcars.com

Rental car ( www.rentalcars.com ) is a website that make a service at the lowest price. In this

system there are several characteristics for this website. Customer can search car and pickup

car based on customer selected location. Provide the service can sent the car to customer

according to designated area. Figure 2.2 shows the interface of Rentalcars system.

2.2.3 Drive.my

This system ( www.drive.my ) is dedicated to find car rental online as easy as possible and

providing onlines servis at location in Malaysia. Customer only input date pickup, return date

and location this system will be find what car was available at that time. Customer can find a

car to match that they needs based on their budgets. Figure 2.3 shows interface of Drive.my

system.

Figure 2.3:Interface of Drive.my

2.3 Research on Different Technique

Different technique in multi-criteria decision method has been analyse. Previous

research and articles that related to the specific technique were observe on their advantage

and disadvantages for implementation the suitable technique in the system. Three technique

were chosen for the literature review.

2.3.1 Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)

The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is a multi-

criteria decision analysis method, which was originally developed by Ching-Lai Hwang and

Yoon (1981) with further developments by Yoon (1987), and Hwang, Lai and Liu

(1993). TOPSIS is based on the concept that the chosen alternative should have the shortest

geometric distance from the positive ideal solution (PIS) and the longest geometric distance

from the negative ideal solution (NIS).

2.3.2 Analytic Hierarchy Process (AHP)

The analytic hierarchy process (AHP) is It was developed by Thomas L. Saaty in the 1970s

who partnered with Ernest Forman to develop Expert Choice in 1983, and has been

extensively studied and refined since then. It represents an accurate approach for quantifying

the weights of decision criteria is a structured technique for organizing and analyzing complex

decisions, based on mathematics and psychology. The application of AHP comprises the

following stages, structuring of criteria and alternative, collecting judgements, calculating

priorities, checking the consistency of judgements, and lastly, calculating the overall priorities

of the alternatives (Maria Celeste de Carvalho Ressiguier Ribeiroa, 2016).

13

2.3.3 Weighted Sum Method (WSM)

The weighted sum (WSM) also called weight linear combination (WLC) or simple additive

weighting (SAW). WSM is the best known and simplest multi-criteria analysis to make a

decision method for evaluating a number of alternatives in terms of a number of a decision

criteria. The current Weighted Sum Method helps the decision maker to choose when the

scenario is static.

2.5 Implementation of Car Rental System using TOPSIS method

From the research, the best algorithm for this system is TOPSIS method. On this table show

how TOPSIS work to search for car in this system.

There are have four cars that was available for rent with three criteria in Table 2.2

This table show that criteria of the car. To get the performance value for all the data in

the criteria it need to calculate by using this formula √𝐸 𝑋𝑛2.

After get the performance value , next go to the data for criteria will be normalise. To

calculate normalised data need to divide data with the performance value.

2.6 Summary

This chapter discuss literature reviews that have been collected and reviewed along the

studies. Literature review can help developer to discover any problems of any existed system

or research that can be improve in future.

As a summary, the integration of Car Rental System with TOPSIS method is the most

suitable to use in this developing system. TOPSIS technique will help user to find car based

on criteria and the system will rank the result with the most ideal one on top while the worst

one on the bottom.

CHAPTER 3

METHODOLOGY

3.1 Introduction

This chapter describes the software development process are involving lots of steps

towards implementation and a standard life cycle steps are followed across this process. The

method that are commonly used as a guideline for solving the problem with certain

components such as phases, tasks, methods, techniques and tools. There are various type of

software development life cycle (SDLC) model. The SDLC that will be used on this project is

waterfall model.

3.2 Waterfall Model

Methodologies in general are defined as a guideline to solve problem with the specific

component such as phase, tasks, methods and technique. It can also be defined as a

systematic method that can be used in a single development designed to solve the problem.

There are various type of models that can be used in the development system such as

Iterative Model, V-Model, Spiral Model and others. In order to implementing this project, the

most suitable methodology is Waterfall Backflow Model which is commonly used in system

development life cycle (SDLC).

System development life cycle is a structured analysis technique that is used to plan

and manage the development system process. System development life cycle is a complete

development process which is includes six phases where the initial phase is planning and end

with the support phase. SDLC approach with more appropriate to the system that will be

developed. Figure 3.1 below shows the Waterfall Backflow Model.

20

Figure 3.1: Waterfall Model

3.2.1 Requirement phase

This is the first phase of development where all the requirements gathered and documented.

In this phase,the project was selected is Car Rental System. Potential requirements,

deadlines and guidelines for the project are analyzed and placed into a functional

specification. This stage handles the defining and planning of the project without mentioning

specific processes.

3.2.2 Analysis phase

In this phase we analyze all the gathered requirements whether the requirements are valid or

invalid.

21

3.2.3 Design phase

In this phase all the system design is analyzed and specified like hardware, system

configuration and architecture or the system. Context Diagram (CD), Data Flow Diagram

(DFD), Level 0, Entity Relationship Diagram (ERD) will show in this phase to develop the

system. These diagrams are designed as a guideline to develop the system. After that the

database and the interface of this system will be develop.

3.2.4 Coding./Implementation phase

At the implementation phase, system will be develop and all the development works are

performed. The diagram of the data flow and the data model will be implemented in this phase.

Programmer will create a coding code of interface. The source code is developed using the

models, logic and requirements designated in the prior stages.

3.2.5 Testing

Once the development completed, testing phase starts and in this phase we test the each unit

or component and make sure the developed components are working as expected. All the

testing activities are performed in this phase.

3.2.6 Deployment phase

Once testing is completed and make sure there is no bug or defect or any kind of issue, then

project is deployed to production. Once product is deployed to production the end users start

using the product.

22

3.2.7 Maintenance phase

We always keep eye on the product and provide all the necessary bug or issue fixes if occurs

in production or reported by end users. Also time to time we keep updated the product with

new updates or patches if developed or available.

3.3 Project requirement

There are two requirements that are needed to develop the system which are software

requirement and hardware requirement. It is important to ensure the development of the

project went well and for the future references.
