CHAPTER 5:

DEVELOPMENT OF TIMETABLE

MANAGEMENT SYSTEM USING

GENETIC ALGORITHM

68

5.1 Introduction

This chapter describes the technology and methodology used in developing the web

based known as Timetable Management System. This chapter describes the system

overview, system objective, system scope, how the system works, software and

hardware considerations, the system development methodology used and finally the

limitations and future enhancements of the system. Requirements are addressed and

justifications on any decisions made are documented.

5.2 System Overview

Timetable Management System is a web based system which is developed for lecturers

and students of FCSIT as their online timetable. It would contain three modules:

administrator module, lecturer module and student module. The functions of the

administrator module are to handle the entire administrator task. Administrator has to

register the entire FCSIT student for the first time. Administrator also has to handle the

additional, editing and deleting classes and subject as well.

For the lecturer module it contains the function to view timetable for the specific

lecturer and the master timetable for that semester. Lecturer can inquire for the class

available and can book for the free classes. Students module contains the functionality

of add and drop subject. Students can view and get the registration slip from the system.

Timetable Management System also contains a database, which stores the lecturers and

students personal details. Only the administrator can view, add and delete the data in the

timetable.

69

5.3 System Objective

The main objective of developing the Timetable Management System is to have a

quality and feasible timetable which is to improve the current system that FCSIT is

using. Another objective is the system should be user-friendly and easy to maintain. The

system produced should be easily modified to address any form of constraints in an

actual situation. The system should also be robust and produce a feasible solution for

any big problem.

5.4 System Scope

The scope of this system is to develop FCSIT timetable management system, which can

improve the current manual system that FCSIT is using. In order to achieve the

objectives, due to the time constraints, the scope of the timetable system covers the

following features and functions: -

� An administrative Section which includes the following:-

� Manage students’ profiles

� Manage lecturers’ profile

� Manage the username, password and change password

� Manage the add, drop subject

� Manage the add, edit and delete class

� Creation of Master Timetable

� A lecturers’ Section which includes the following:-

� View and print their own timetable

� View and print master timetable for one semester

� Query on the class availability

� Booking the class

� Creation of lecturer’s timetable

70

� A students’ Section which includes the following:-

� Add and drop subject

� View, print their timetable and registration slip

� Change password

� Creation of student’s timetable

5.5 Software, Hardware and technology considerations

In order to develop a good web based system, it is very important to choose the correct

hardware, software and technology. Below are some explanations of the hardware,

software and technology chosen as development tools for the Timetable Management

System using Genetic Algorithm.

The following Sections discuss the scripting language, graphic design tool, database

technology, web development tool, and the server technology used to develop the

timetable system. In order to develop a better website with the latest technology, the

researcher went for a few training sessions to learn about the newest technology,

software and languages.

5.5.1 Programming / Scripting Language

� PHP Programming

PHP originally stood for “Personal Home Page” as it was created in 1994 by Rasmus

Lerdorf to track the visitors to his online resume. As its usefulness and capabilities

grew, it came to mean “PHP: Hypertext Preprocessor” (Ullman, 2003). PHP can be

interspersed within Hypertext Markup Language (HTML), which makes developing

dynamic websites more accessible.

71

PHP was selected to develop the Timetable Management System because it is a server-

side, cross-platform technology. Server-side actually refers to the fact that everything

PHP does occurs on the server instead of the client’s site. Its cross-platform means that

PHP runs on most operating systems, including Windows, UNIX, and Macintosh. More

importantly is that PHP written on one server will normally work on another with little

or no modifications. Besides that, when it comes to developing dynamic websites, PHP

is better, faster and easier to learn than the alternatives. Of course, the main reason for

PHP being chosen to develop the website is it comes at no cost (PHP is open source).

5.5.2 Graphics’ Design Tools

� Adobe Photoshop CS

Adobe Photoshop was chosen to be used as one of the graphic editing software because

it is professional image-editing software which provides a comprehensive toolset, and

powerful creative options to help people create professional-quality images for web,

print, and other emerging media.

� Macromedia Fireworks MX 2004

Fireworks MX was chosen to be used as the other graphic editing software, because it is

an increasingly approachable application with enhanced power to create graphics and

interactivity for websites.

5.5.3 Web Development Tool

� Notepad

Microsoft Notepad version 5.1 was chosen as the text editor to develop the website as

well since the researcher is more familiar with using the text editor to develop a

website.

72

� Macromedia Dreamweaver MX 2004

Macromedia Dreamweaver MX 2004 was chosen as the web development tool because

it can work in a single integrated environment to create, build and manage a website.

Dreamweaver MX uses user-friendly visual layout tools, rapid web application

development and extensive code editing support, which is easier to learn and use.

5.5.4 Database and Technology

� MySQL

MySQL is a database management system (DBMS) for relational databases (therefore,

MySQL is an RDBMS), a database being a collection of interrelated data, be it text,

numbers, or binary files, that are stored and kept organized by the DBMS (Ullman,

2003).

MySQL was selected to develop the database for this web based system because like

PHP, MySQL offers excellent performance, portability and reliability, with moderate

learning curve at little to no cost because MySQL is the world’s most popular open

source database. Besides that, another reason for it being chosen is PHP has good

support for MySQL.

5.5.5 Hardware Requirements

Below is the list of hardware requirements for the personal computer to develop the

Timetable Management System:-

� Intel Pentium IV 500MHz processor or higher

� 128MB DDR-Ram (256MB is recommended)

� 10GB Hard-disk space or higher

73

� 40x CD-ROM

� 15” Monitor (can support up to 1024X768 Resolution)

� 56Kbps Modem

� Keyboard and Mouse

5.6 System Analysis

System analysis, sometimes called requirement analysis, is the process of gathering

information about the current system, identifying its strengths and problems, and

analyzing them to produce a concept for the new system. The goal of this analysis stage

is to truly understand the requirements for the new system and develop a system

concept that addresses them. In the current case, there is a current system that used in

FCSIT. The analysis that will be done would be on how a current system works and the

new requirement to improve the timetable system.

5.6.1 Current Timetable System

The current manual timetable system is use by postgraduate and undergraduate. This

manual system will make sure there are no clashes for the every timetable produced.

The current timetable always change and involved many lecturer to handle it. It’s taking

too much of their time. The conclusion is they need a system to help and improve the

process of preparing the timetable.

5.6.2 User Analysis

The users of this system are divided into three categories. The first category would be

the lecturers who need their own timetable and master timetable for the semester. They

also want to enquire if the class is available or not to do the additional or replacement

class and can book the class straight away. The second category would be the students

who want to add and drop the subject. They also can have their timetable and

registration slip. The third category would only contain the administrator, who would be

74

able to monitor and control the Timetable Management System, which includes the

lecturers and students ‘data.

5.6.3 Content Acquisition

The contents of Timetable Management System, which include text and graphics,

would be acquired from the following sources described below.

� Text

Most of the text content are look and feel used in Timetable Management System is

taken from a few scraped ideas and going through reference materials during the

literature review and research studies.

� Graphics

As graphics plays an important role to attract browser attention, creative and nice

graphics are needed. Most of the graphics are downloaded from the Internet and further

modified using either Adobe Photoshop of Macromedia Fireworks. The logo and banner

are created using Adobe Photoshop.

5.6.4 Use Case

UML use case diagrams are used to describe the main processes and functionality of the

Timetable Management System. The purpose of having use case diagram is to identify

the scope of the system. Three use case diagrams have been created for timetable

system: one for the lecturer, students and the administrator.

75

Figure 5.1: Lecturer’s Section Use Cases

Lecturer can log-in to Timetable Management System, using their usernames and

passwords. System displays the main menu if log-in is successful. If the username and

password are not accepted, system displays a message indicating that the username or

password is invalid. Once the lecturer logs in, he or she can perform the processes (use

cases) like view class, view timetable, view master timetable, inquiry class available,

class booking and change password.

76

Table 5.1: Lecturer’s Section Use Cases Description

Use Case Description

Log-in Lecturer need to log in using the username and password giving

by the administrator

View Class Lecturer can view class, by using this function they can see the

subject code, credit hour, class, day and time.

View Timetable Lecturer can view their timetable by using this function

View Master Timetable Lecturer can view the master timetable for the semester.

Inquiry Class Available All lecturers are allowed to inquire the class available for the

semester.

Class Booking All lecturers can book class if they want to do the additional class.

Change Password Lecturers can change password if necessary

Figure 5.2: Student’s Section Use Cases

77

Student can log-in to Timetable Management System, using their usernames and

passwords. System displays the main menu if log-in is successful. If the username and

password are not accepted, system displays a message indicating that the username or

password is invalid. Once the student logs in, he or she can perform the processes (use

cases) like add subjects, drop subject, view timetable, view registration slip and can

change password.

Table 5.2: Student’s Section Use Cases Description


Log-in Student need to log in using the username and password they have registered when they first time use the system

Add Subject Student can add subject with regards to the subject suggestion by

the Dean.

Drop Subject Student can also drop the subject if unnecessary

View Timetable Student can view the timetable for the semester.

View Registration Slip Student can view and print the registration slip for the semester.

Change Password Student also can change password if necessary

78

Figure 5.3: Administrator’s Section Use Cases

The administrator does not need to register, as his or her username and password is

fixed in the database. The administrator needs to log in to Timetable Management

System in order to manage the system. Besides logging in, the seven main use cases for

the administrator are student registration, lecturer registration, add class, edit class,

delete class, add subject, edit subject and delete subject.

79

Table 5.3: Administrator’s Section Use Cases Description


Student Registration The administrator has to key in the student’s profile. After that the

registered student can use this system

Lecturer Registration The administrator has to key in the lecturer’s profile and can

proceed to register the subject

Add Class The administrator can add the new class by insert information

about the class description, class code, class capacity and class

location

Edit Class Administrators can edit the current and new class if necessary.

Delete Class The administrator is allowed to delete the class if the class is no

more to use.

Add Subject The administrator is allowed to add subject if the subject is new subject for the semester.

Edit Subject The administrator is allowed to edit the subject if necessary.

Delete Subject The administrator is allowed to delete subject. After pressed

delete, a window will prompt out to ask for delete confirmation.

5.6.5 Work Flow Modeling

Activity diagrams are used here to model the flow between the different components.

An activity diagram is needed because the researcher wants to model the workflow of a

use case, and it can show the paths within the use case as well as other use cases. With

activity diagrams, the researcher will be able to illustrate where functionality exists in

the system and how the functionality coordinates with the functionality of other pieces

of the system. The researcher has developed ten activity diagrams for this system. A

brief description will be given to each of the activity diagram in the following pages.

Figure 5.4 above shows the activity diagram for Log-in. First, the lecturers, students and

administrator need to log in using the username and password that was created during

registration. The system will validate the username and password. If the password or

username is invalid, an error message will be displayed and the lecturer or student or

administrator can try to log in again. If log in is successful, the system will identify the

user as a lecturer, student or an administrator. If the person logs in as administrator, the

administrator’s menu page will be displayed; else the lecturer or student menu’s page

will be displayed.

successful deleting the subject or class, a successful application page will be display. If

validation failed, an error message window will pop up.

91

5.6.6 Process Modeling

The process model is used to describe how the system operates. It illustrates the

business processes or the activities that are performed and how data moves among

them. It can be used to describe the system being developed.

There are so many different process modeling techniques. The researcher used Unified

Modeling Techniques (UML) for the process modeling. UML Sequence diagrams are

used to show the interaction between objects and to illustrate the activities that are

performed in Timetable Management system and how data moves around in this

system.

As described earlier, the users of Timetable Management System are divided to three

categories: Lecturer, Student and Administrator. Each category of user can perform

only certain tasks as fixed by the system. The General tasks of lecturer, student and

administrator are shown in the use case diagram in Figure 5.1, Figure 5.2 and Figure

5.3. The following sequence diagrams show the interaction between objects arranged in

time sequence.

Figure 5.15: Sequence diagram for lecturer/student/administrator Login

92

Figure 5.15 above shows a sequence diagram for the use case Login. The vertical

dimension represents time and all objects involved in the interaction are spread

horizontally across the diagram. Lecturer, student and administrators will need to log in

to the Timetable Management System. In order to log in, the lecturer/student

/administrator need to key in their username and password. Then the browser will send

the information to the web server and validate the information with the database.

Successful validation will be sent to the web server, and the server will display the Main

Menu page according to the user type. As for unsuccessful validation, the server will

send an error login page to the monitor.

Figure 5.16: Sequence diagram for the use case View Class, Timetable or Master

Timetable

Figure 5.16 shows a sequence diagram for the use case view class or timetable or master

timetable. After the lecturer requests to view class or timetable or master timetable, a

query result will be returned by the web server and a profile page will be displayed by

the browser.

Figure 5.17 shows a sequence diagram for the use case inquiry class available and

booking class. First, the lecture will inquiry for the available class and then the browser

will inquiry the URL for the class available from the server. After that, the web server

will send the HTML and display the result. If the lecturer wants to book the class, he or

she has to fill the information, all the information are sent to the web server for booking

validation. If validation is successful, the query will pass to the database and after the

data is stored successfully, an application successful webpage will be display. If the

booking validation fails, a window will pop out to show the error message and request

the lecture to fill in the information again.

94

5.7.3 Screen/Interface Design

The purpose of the user interface is to provide users with a comfortable and convenient

means of accessing the website. The flexibility and convenience of the interface is a

major factor determining the overall success of the website. Timetable Management

System is a web base that allows the interaction between Internets users, therefore their

needs are of the utmost importance. Therefore, the web based uses the technology of

hyperlinks, buttons and navigation bars which the majority of Internet users are familiar

with. This means that Internet users can easily access information with just a click of a

mouse button.

Timetable Management System web based’s interface design will be made up of simple

but effective presentations that can attract the Internet users’ attention. There are

minimum graphics so they won’t clutter the page design and to ensure that the website

will load at the shortest possible time frame because most Internet users are put off by

sites that takes “years” to load. Besides that, interface consistency is maintained

throughout the site so that there is uniformity in the website that will not cause

confusion to the users. Below will be the screen design of Timetable Management

System.

5.8 System Development

The objective of the development phase is to convert the deliverables of the design

phase into a complete system. Most activities in the development phase addresses the

computer programs that make up the system, but this phase also puts in place the

hardware, software, and communications environment for the system and other

important elements of the overall system.

The activities in the development phase translate the system design produced in the

design phase into a working system (web based). The development phase includes

activities for developing the system, testing the system, and to ensure the system

functions satisfy the functional process requirements. At the end of this phase, the

system will be ready for the activities of the testing phase.

113

The Timetable Management System web base was developed after the system analysis

and system design phases. After gathering data from the system analysis stage and

designing the web base, the development is divided into three main sessions which are

explained in the Sections below.

5.8.1 Graphic Development

In order to develop a nice and attractive web site a lot of graphics, such as banners,

logos, buttons, background wallpapers and pictures are needed. Some of the pictures

were downloaded from other websites and edited using Macromedia Fireworks MX or

Adobe Photoshop 8. These two software were chosen to be used to design, create and

edit the graphics because the researcher found them easy to be learn and quite powerful

in the sense that they have a lot of features. Some of the graphics, such as some buttons

and the logo are designed by the researcher from scratch.

5.8.2 Database Development

The Timetable Management System used a relational database in its database

implementation because it can support multiple tables that store each item only once,

thus significantly reducing storage place. The database was created and using MySQL,

which is a GUI Client that works alongside MySQL Database server. All the tables as

described in Section 5.8.2 are developed on localhost and export to domain host using

myPHPadmin, when uploading the website.

5.8.3 Website Development

In this stage, the researcher converts the deliverables of the web design into a complete

website using Macromedia Dreamweaver MX, PHP programming, and MySQL

database. Each webpage is developed according to the design from the design phase.

114

Although Macromedia Dreamweaver is used as the main tool to develop Timetable

Management Syatem, but a lot of the back end processing still need to be hard coded

using PHP programming. The source code for the web portal is not printed out in this

documentation because there are too much of codes for all the pages. However, in order

to view the source code, at least one web development tool such as Macromedia

Dreamweaver or Microsoft Front Page, or a word editor is needed.

The website was developed and tested on a local host first before it’s uploaded to a

domain host. Timetable Management System can be accessed temporarily through

http://localhost/subjectTT/mainframe.php for the purpose of the dissertation.

5.9 Testing

The objective of this testing phase is to prove that the developed system (Timetable

Management System) satisfies the requirements defined earlier. Several types of tests

will be conducted in this phase. Testing is an important phase of system development

because it can ensure the system matches the specifications. Besides that, testing also

ensures that the system functions in the correct and proper manner with the minimum

amount of errors.

Websites are susceptible to bugs and malfunctions, such as broken links, links that go to

the wrong page, video and audio that not play properly, and scripts that not run

properly. Besides that, there might be browser compatibility problems because a project

may run perfectly on one browser but may not display properly on another browser.

115

Bottom-up testing strategy is used in this system to avoid unnecessary duplication of

effort. Individual objects will be tested in isolation using unit testing and gradually

integrated for the higher-level integration testing and system testing. Failed components

will be migrated back to the development phase for rework, and components that work

properly will migrate ahead for implementation.

5.9.1 Unit Testing

Unit testing reveals syntax and semantic errors from the smallest programming unit. In

this thesis, unit testing is used to test each individual webpage. Errors that are found in a

particular page of the website are thoroughly debugged and removed before starting to

develop another webpage. Due to the dynamic nature of testing, there is no proper

testing documentation created.

5.9.2 Link /Integration Testing

When each webpage of a particular Section in the Timetable Management System

passed the unit testing, integration test was carried out to ensure that pages are linked in

the correct flow and integrate properly into the entire website. Integration testing was

mainly conducted in “Administrator Module” Section “Lecturer Module” and “Student

Module” Section. All the buttons, hyperlinks and navigation bars were tested. Please

refer to Appendix E for test results.

5.9.3 System Testing

A system test was carried out to test the web base as a whole when the entire website is

finish and uploaded. It was checked to ensure that it works perfectly once it’s uploaded

to the server. It also tested whether there are any broken links in the entire website since

it’s transferred from the local host to another domain hosting company.

116

5.9.4 User Testing

For the user testing, involved two timetable committee members of FCSIT, one lecturer

FCSIT and one assistant registrar FCSIT to confirm that the developed system meets

the user requirements. User testing shall be done in a simulated “real” user environment

with the users using simulated or real target platforms and infrastructures. Therefore

user testing for this system is tested on the researcher’s laptop with a personal web

server. During the user testing stage, users tested the Timetable Management System

and were required to fill in the system evaluation form as shown in Appendix F. The

users’ feedback is summarized in Table 5.5 below.

117

5.10 System Implementation

In this phase, the system or system modifications are installed and made operational in a

production environment. The system implementation phase is initiated after the system

has been tested and accepted by the user. Activities in this phase include notification of

implementation to end users, execution of the previously defined training plan, data

entry or conversion, and post implementation review. Timetable Management System

118

is only a system developed for this dissertation. Therefore, there is no proper

documentation for this phase.

5.11 Limitation Of The System

Timetable Management System was created for the use of FCSIT. All the basic

requirements of a timetable such as timetable for student and lecturers, master timetable

for lecturers, enquiry for free classes and booking for the free classes are available. The

main limitation with Timetable Management System is that it is not linking to the

current student database. This is because if the system connects to the current database

the requirement for the hardware and software is higher.

Besides that, another limitation is that the FCSIT must have a permanent administrator

to maintain the database in the system. Administrator has to key in the data and lecturer

for the first time registration.

5.12 Future System Enhancement

The Timetable Management System can be further enhanced by adding the following:-

� Linking to the ISIS database. So that, the University has one reference database.

� With the linking to ISIS database, the task for the administrator is less. This is

because the student data is taken from the ISIS database.

5.13 Conclusion

Generally, this system can be considered a useful system since it helps the lecturer to

improve their process of preparing the timetable. By providing support through the

Timetable Management system, the usage can be increased to any faculties instead of

FCSIT only.

119

Timetable Management System is not yet uploaded to the host. If the system is

successfully upload to host, to assist administrator, lecturer and student on how to use

the system, a user manual for administrator is included in Appendix A, a user manual

for lecturer is included in Appendix C and user manual for student is included in

Appendix B.
