CHAPTER 1 - INTRODUCTION1.1 System requirements

1.1.1 Rationale

The metro system is an urban rail public transport network operating

underground or overhead, has gained popularity worldwide Modern metro systemshave been successfully implemented and operated in major cities such as London,Tokyo, Paris, and New York, effectively addressing issues of traffic congestion,environmental pollution, and providing efficient and comfortable transportation forthe public The Urban Railway System in Ho Chi Minh City is a large-scale

megaproject aimed at solving many traffic problems, improving the people's quality

of life and the sustainable development of the city Metro line No 1 Ben Thanh Suoi Tien is the first line built in this great project Its successful implementationand operation are crucial steps in advancing the investment and development of themetro system, thereby fostering the overall sustainable development of the nation

-1.1.2 Problem statement

In spite of the Metro's emergence as a noteworthy and favored mode of publictransportation, there continue to be certain challenges in its management and

operational efficiency, thereby causing impact on movement Noteworthy

challenges encompass the refinement of algorithms for timetable management,continuous monitoring of system status, and efficient resolution of technical issues.Metro systems globally often grapple with the complexities of synchronization andadherence to schedules, culminating in congestion and prolonged waiting periodsfor passengers Prudent oversight of unstable states and proficient technical

troubleshooting remain essential to ensure the security and effectiveness of thesystem Insufficient execution of these responsibilities can result in malfunctions

and service disruptions, necessitating vigilant monitoring and evaluation of the dualsystem's vehicle status, station conditions, and related components.

Recognizing the challenges and deficiencies prevalent in the operational

procedures of Metro systems worldwide, and drawing particularly from the

practical insights gleaned from the operational history of the Cat Linh - Ha Dongline in Hanoi, the research team embarked on the development of a sophisticated,secure, and highly efficient operational model aimed at maximizing the efficacy ofthe urban railway system within Ho Chi Minh City The ramifications of adopting

an ineffectual operational paradigm are far-reaching, encompassing potential delays,asynchrony, compromised security protocols, technical disruptions, diminishedoperational performance, escalated expenditure, and an undue strain on the city'sinvaluable resources and assets

1.2 Objectives

The primary aim of this study is to develop a comprehensive, adaptable, andprecise simulation model using the Arena simulation software This model seeks toaccurately depict the crucial operational phases of Metro Line 1, which spans fromBen Thanh to Suoi Tien in Ho Chi Minh City To enhance the simulation's

authenticity and relevance to reality, several scenarios have been embraced

Particularly, insights have been drawn from the practical experience of the Cat

Linh-Ha Dong line in Hanoi, shedding light on its strengths and limitations Theseinsights serve as a foundation for proposing enhancements and solutions to elevatethe performance and safety of the urban railway system

Through the utilization of this simulation model, a model is established forfine-tuning, assessing, and managing the operational intricacies of Metro Line 1.The model affords the flexibility to conduct experiments and attain results within asimulated environment, all the while safeguarding the integrity of the actual

system's operations Furthermore, the incorporation of visual elements and datawithin the model fosters an enriched and intuitive representation of the system'sactivities, ensuring a vivid and lucid illustration.

1.3 Scope and limitations

1.3.1 Scope

The purview of this simulation model is concentrated on the Ben Thanh - SuoiTien Metro Line, the first line of the Ho Chi Minh City Urban Railway System.This decision is extremely important since it will lay a foundational stone for

forthcoming lines The scope of simulation includes a variety of elements,

including timetable management, control over system state, and engineering

technologies and innovative methodologies, thereby culminating in an optimization

of operational paradigms Furthermore, the project seeks to assess the

environmental and social impacts of metro line operations, catalyzing the

development of overall measures to protect the environment and society The

overarching aspiration is to ensure the unfaltering and sustainable progression ofthe urban railway system both in Vietnam and on an international scale

from the unavailability of empirical data due to the non-operational status of theMetro line under study This circumstance posed challenges in the data collectionprocess, necessitating reliance on online sources that, while informative, might lackcomprehensive detail and precision Moreover, logistical challenges, includinggeographical distance and temporal restrictions, impeded the team's ability to

conduct exhaustive on-site evaluations of operational metro models, which couldhave provided a deeper understanding of operational intricacies

Another limitation pertained to the lack of expertise of the team with the

specialized domain of simulation The endeavor to construct an accurate and

effective simulation model demanded extensive literature review, research, and theacquisition of simulation techniques This undertaking consumed considerable timeand effort, compounded by occasional difficulties in seamlessly integrating newlyacquired insights into the model

Furthermore, owing to temporal and resource constraints, the scope of themodel could not encompass every nuanced aspect Many operational aspects andbasic assumptions are made in operations and operational procedures that the teamhave not been able to fully survey and simulate Notwithstanding these constraints,the research team has constantly tried to overcome the difficulties Efforts wasexerted to devise a simulation model that, contributes significantly to the broaderdevelopment of the future Metro system

CHAPTER 2 - SYSTEM DESCRIPTION

2.1 Conceptual design

2.1.1 Idea

The Ben Thanh-Suoi Tien Metro Line simulation model has been

meticulously created to replicate the operational processes and offer a thoroughoverview of the crucial phases of the system's operations This project aims to

illuminate the actual operational environment in which metro trains operate,

improving our comprehension of the operational complexities of the metro line andensuring its efficiency and safety during routine operations

The simulation model for the Ben Thanh–Suoi Tien Metro Line consists ofthree main sections, each of which clearly represents an important operational

phase The first section covers the planning stage and includes activities like

staffing, timetable verification, and system status evaluations, all of which togetherensure that the system is ready for takeoff The next section is the operational phase,when trains travel along their predetermined routes, stop at intermediate stations,and perform positional verifications to ensure uninterrupted and secure operations

In the final section, the termination procedure is covered, including passenger

compartment inspections and culminating at the depot

Line 1 of the metro system represents the inaugural network to be

commissioned within the greater Metro system of Ho Chi Minh City

Encompassing a comprehensive route span of 19.7 km, this particular metro linehas the capacity to efficiently accommodate a maximum of 930 passengers withineach train car Revered for its intrinsic convenience, rapidity, and operational

efficiency, this endeavor anticipates a notable surge in ridership for Line 1 in theforthcoming future, thereby potentially mitigating the prevailing constraints of thecity's existing traffic infrastructure This train route consists of a total of 14 stations,

comprising 3 subterranean stations (Bến Thành, Nhà hát Thành phố, and Ba Son)and an additional 11 elevated stations (Văn Thánh, Tân Cảng, Thảo Điền, An Phú,Rạch Chiếc, Phước Long, Bình Thái, Thủ Đức, Khu Công nghệ cao, Suối Tiên,Bến xe Miền Đông), and Long Binh deport The inter-station distances oscillatebetween 0.6 to 3.0 km, offering a strategically planned distribution.

2.1.2 Flowchart

2.1.2.1 General flowchart

The operation process of the Ben Thanh-Suoi Tien Metro Line begins with the

"Initiation" phase, encompassing staff assignments, timetable verification, and anoverall system status check to ensure comprehensive readiness for the upcomingjourney at the departure station Subsequently, the train moves to the initial

departure station and enters the "Departure" phase During this phase, the train setsoff from the initial station and follows the predetermined trajectory

The "Travel" phase extends throughout the journey, with the train makingstops at intermediate stations to facilitate passenger embarkation and

disembarkation The system continuously checks the train's position, ensuring thatthe operation proceeds safely and in compliance with regulations Notably, thecondition of the entire system and critical elements at each station is assessed tomaintain control

As the final station approaches, the system conducts an overall safety check ofthe train and ensures passenger safety before concluding the journey Subsequently,the train moves to a stopping point, and the operation process concludes with the

"Stop" phase
