THESIS SUMMARY
Freight management is an important area of economic and social development,
playing an important role in connecting localities and bringing products to their
destination. However, we recognize that the current management of freight
transportation is still limited and difficult, making it difficult to ensure the safety and
efficiency of the transportation of products.
The main limitations and difficulties we have noticed include the lack of
coordination between transport management units. Lack of this leads to heterogeneity
in management, which makes it difficult to coordinate and organize transport
activities. We also recognize that lack of accurate information and data is a major
barrier, making planning and decision-making in transportation management difficult
and unreliable.
In addition, we also realize that strict control and supervision during the
transportation of products also face many difficulties. Lack of routine monitoring and
inspection makes it difficult to detect and promptly handle violations, fraud, or
emergency situations during transportation. This contributes to a decrease in the
efficiency and safety of freight transport.
We also recognize that the lack of technology application in transportation
management is an important problem. Information technology and management
software are developing strongly in other fields, but in transportation management,
the application of technology is still limited. This shortage has deprived the
opportunity to optimize the management process, from tracking and monitoring, to
the organization of schedules and route optimization.

In response to these problems, we decided to choose the topic "Development of
Transport Management System" to research and develop a more effective
transportation management system. We want to create an intelligent transportation
organization and management system, including providing accurate information and
data, applying technology to optimize the transportation process, and integrating

12


traffic law lookup tools to help solve difficulties related to traffic law regulation and
compliance. We believe that this system will contribute positively to improving
efficiency and safety in freight management, contributing to promoting economic and
social development.

GENERAL INTRODUCTION

1.1. Reason to choose the topic
In today's increasingly complex and fiercely competitive business environment,
logistics enterprises face many challenges in terms of transportation management and
compliance with relevant legal regulations. The effective organization and operation
of transport activities is an important factor to ensure the success and competitiveness
of businesses in this industry.
Moreover, in the field of logistics, grasping and complying with regulatory
regulations is a mandatory requirement. However, with the continuous development
of legislation and the constant change in regulations, finding and properly applying

legal documents becomes complicated and time-consuming and laborious.
With these challenges and needs, developing a transport management system
and integrating regulatory document lookup in logistics business management is a
reasonable choice. This helps to provide a comprehensive and efficient solution to
manage transportation operations and at the same time ensure compliance with legal
regulations.
This system will help optimize the transportation management process, from
planning, monitoring, coordination, to evaluating and improving operations. At the
same time, the integration of legal document lookup in the system will help
businesses quickly access and properly apply regulations, minimize legal risks and
ensure compliance with relevant regulations.
Therefore, researching and developing transport management systems and
integrating legal document lookup in logistics enterprise management is a topic of
interest and significance in improving the operational efficiency and competitiveness
of logistics enterprises in today's business environment.

BACKGROUND

2.1. Technology used
2.1.1.

Programming languages

2.1.1.1.

Java

Java is a popular and powerful programming language developed by Sun
Microsystems (now Oracle). It is designed to be simple, portable, cross-platform and
secure. Here are some of the characteristics and benefits of Java:
• Simple and easy to learn: Java has a clear and straightforward syntax, making
it easily accessible to beginners. It provides basic concepts such as classes,
objects, methods, and interfaces, making building complex applications a
breeze.
• Cross-platform: Java source code is compiled into bytecode, an intermediate
language, and runs on the Java Virtual Machine (JVM). This allows Java
applications to run on various operating systems and platforms without
changing the source code.
• Security: Java has a robust security environment, which helps prevent security
issues such as unauthorized access and malicious code execution. The Java
Virtual Machine (JVM) controls access to resources and limits malicious
activities.

• Large libraries: Java comes with a large number of standard libraries that
provide packages and classes to perform a variety of tasks. These libraries help
speed up development and reduce the effort required for application
deployment.
• Multithreading support: Java supports multithreading, allowing multiple jobs
to be handled simultaneously. This helps optimize application performance
and get the most out of multi-core computers. Object support: Java is an
object-oriented programming language (OOP) with the creation of objects and
the use of concepts such as inheritance, encapsulation, and polymorphism.
This increases organization, code reuse, and easy application maintenance.
• Rich community and documentation: Java has a large and vibrant community
with many resources, forums and open libraries. This helps solve problems,
learn and share knowledge with the worldwide Java developer community.
Within the scope of the course, Java is used to program the SpringBoot
framework.

20


2.1.1.2.

Kotlin

Kotlin is a modern, static, and object-oriented programming language,
developed by JetBrains. Kotlin is designed to provide the features and benefits of
Java, but with a concise syntax, more security, and better support for functionoriented programming. Here are some of the characteristics and benefits of Kotlin:
Keep it short and simple:
• Kotlin provides a concise and easy-to-understand syntax, which reduces the
amount of source code compared to Java. This creates code that is easy to read,
maintain, and helps increase developer productivity.

• Backwards compatible with Java: Kotlin is fully backwards compatible with
Java, allowing you to use existing Java libraries and call Java code from
Kotlin. This makes it easy to convert and integrate Kotlin into existing Java
projects without rewriting the entire source code.
• Safety and security: Kotlin provides static type checking to detect compilation
errors during development. It also supports safety features such as null safety
and access modifiers to minimize runtime errors and improve application
stability.
• Support for function-oriented programming: Kotlin supports function-oriented
programming features such as higher-order functions, lambda expressions,
and concise syntax. This allows you to write code that is concise, easy to read,
and more flexible in handling complex tasks.
• Community and development materials: Kotlin has a large and active
community, with many open documentation, forums, and libraries. This makes
it easy for Kotlin developers to find support, share knowledge and take
advantage of available resources.
Within the scope of the course, Kotlin is used for Android application
programming.
2.1.1.3.

Python

Python is a powerful, easy-to-learn, and multi-purpose programming language.
Developed in the 1990s, Python quickly became one of the most popular languages
in the world. Here are some of the characteristics and benefits of Python:
• Simple and readable syntax: Python has a simple syntax, which closely
resembles natural language, making coding easy and straightforward. This

21

simple syntax also helps minimize syntax errors and increase the organization
of the source code.
• Cross-platform support: Python can run on multiple operating systems such as
Windows, macOS, and Linux. This allows you to develop and deploy Python
applications across a variety of environments without changing the source
code.
• Large community and rich documentation: Python has a large and enthusiastic
community of programmers. This community provides many open
documentation, forums, and libraries to support development and problem
solving during programming.
• Object-oriented programming: Python supports object-oriented programming
(OOP), which allows you to use concepts such as classes, objects, inheritance,
and polymorphism. This makes it easy to organize the source code and reuse
it.
Within the scope of the course, Python is used to program the FastAPI
framework.
2.1.1.4.

TypeScript

TypeScript is a typed superset of JavaScript that adds static typing to the
language. This means that TypeScript can help you catch errors at compile time,
rather than at runtime. Here are some of the characteristics and benefits of
TypeScript:
• Static typing: TypeScript's static typing can help you catch errors at compile
time, which can save you time and frustration.
• Classes and interfaces: TypeScript's classes and interfaces can help you write
more organized and maintainable code.
• Modules: TypeScript's modules can help you organize your code into logical

units, which can make it easier to understand and reuse.
• Interoperability with JavaScript: TypeScript code can be compiled to plain
JavaScript, so you can use it in any JavaScript environment.
Within the scope of the course, TypeScript is used to program the ReactJs and
NestJs frameworks.

22


2.1.2.

Framework

2.1.2.1.

Android

In this topic, the driver application will be run on the mobile application, so we
will use the Android framework for development. Android framework is a framework
used to develop software on the Android operating system. Thisproject also uses the
Google Maps library to assist drivers in tracking location during transport.
2.1.2.2.

Spring Boot

Spring boot has the features of Spring Framework. Using Spring Data JPA
integration is a technology based on ORM and Hibernate platforms that allows
creating automatic databases with many database types suitable for future database
changes. Besides, Spring boot also supports:
•

•
•

•
•

Create standalone application, which can run using java -jar (for java web as
well)
Directly embed server applications (Tomcat, Jetty ...) so there is no need to
deploy WAR files
Less configuration, automatic configuration whenever possible (Reduced
coding time, increased productivity), automated libraries like lombok reduced
boilerplate code.
The system architecture is clear, easily accessible, which is the foundation for
later development.
The ecosystem revolves around Spring Boot:
o Reduce the need to write a DAO class.
o Can easily customize queries to suit the purpose of use.
o Easily create a connection with the server using Java config.
Within the scope of the topic, we use Spring Boot framework to develop the

majority of services related to transportation operations.
2.1.2.3.

FastAPI

One of the new and powerful frameworks of Python FastAPI is a great choice
for developing RESTful APIs in Python because it is as fast and convenient as the
name implies. For those who have ever been exposed to OpenAPI or specifically
Swagger will surely know the convenience of being able to interact directly with API

23


documentation easily through just a link, FastAPI has integrated extremely well with
Swagger thereby providing a fast API development ability, full-featured and standard
OpenAPI. The ecosystem revolving around FastAPI also supports very well including
documentation resources and API security by integrating with JWT.
Within the scope of the topic, we use the FastAPI framework to develop the
service in charge of authentication and decentralization.
2.1.2.4.

NestJs

NestJS is a web application development framework based on Node.js. It is built
on the basis of TypeScript and uses concepts from Angular to build server-side
applications that are efficient and easy to maintain. NestJS helps programmers build
web applications in a structured and manageable way. It offers features such as
dependency injection, module-based architecture, decorators, and other powerful
development tools to increase performance and flexibility in the development
process.
With NestJS, we can build RESTful, gRPC, GraphQL and real-time web
applications. It also supports connecting to databases through ORMs (ObjectRelational Mapping) such as TypeORM and Sequelize. NestJS offers a large
community and diverse support from the development community. It is considered a
robust, reliable, and suitable framework for building cross-platform web applications
in a Node.js environment.
Within the scope of the topic, we use NestJs framework to develop a service in
charge of managing multi tenant systems.
2.1.2.5.

ReactJs

ReactJS is a popular JavaScript framework developed by Facebook. It is widely
used to build dynamic and interactive user interfaces in web applications.
ReactJS makes web application development easy and efficient by using
reusable components. These components allow you to build complex user interfaces

24


by combining small components together. One of the strengths of ReactJS is the use
of Virtual DOM (Document Object Model). Virtual DOM optimizes performance by
updating only the necessary elements when data changes, instead of updating the
entire DOM.
ReactJS also has a large and rich community, offering many libraries and
support tools. It is also easily integrated with other technologies such as Redux for
application state management. With its flexibility and efficiency in building user
interfaces, ReactJS is a popular choice for cross-platform web application
development.
Within the scope of the topic, we use the ReactJs framework to develop
interfaces for Web applications.
2.1.3.

Databases

2.1.3.1.

PostgreSQL

PostgreSQL is a popular open source relational database management system.

PostgreSQL supports many advanced features, including multi-user support, ACID
(Atomicity, Consistency, Isolation, Durability) transactions, powerful query and
management toolchains. It also supports many data types such as integers, real
numbers, strings, dates, and other special data types.
PostgreSQL provides a powerful query language, SQL (Structured Query
Language), for performing queries and manipulating databases. It also supports
extensive features such as user-defined functions, space indexing, and external
extensions. One strong point of PostgreSQL is its high stability and reliability. It is
widely used in enterprise applications and critical systems, especially in
environments with high requirements for concurrency access and fault tolerance. In
short, PostgreSQL is a powerful, reliable and flexible database management system
that is favored in the development and user community.
