1. Introduction介绍

1.1 Scope1.1适用范围
本文的主要目的是短暂的过程中如何进行技术方案对用户的要求组运动期间，为伦敦和曼彻斯特之间的HS2标准类的车厢设计。在这种情况下，将详细分析来自不同利益相关者的两个主要需求——乘客和列车管理人员，然后分别针对各自的技术解决方案。
The main purpose of this paper is to brief the process of how we have carried out the technical solution to the user’s requirements during the group exercise, which is to design of standard class carriage for HS2 between London and Manchester. In this case, two main requirements from different stakeholders— passengers and train managers will be analysed in detail, followed by the technical solutions for each of them, respectively.
1.2 Methodology1.2方法
V模型是一个术语，它有助于对复杂模型的更简单的理解，用于演示我们执行的详细过程，如图1所示。在下面的部分中，主要讨论了两个主要利益相关者（乘客和列车经理）的需求，功能和物理分解的需求，将在本文中随后进行验证和验证。
V- model isa term that can contribute to the simpler understanding of a complex model, being applied to illustrate the detail process that we carried out, which is showed in Figure 1. In the following parts, requirements of two main stakeholders (passengers and train managers), functional and physical decomposition of the requirements would be mainly discussed while validation and verification would be also covered subsequently in the present paper.

2. Requirements and decomposition要求和分解

In the first step, my group summarised the relevant stakeholders that are associated with the standard class carriage of HS2 in this team task, which has been listed in Table 1. Among the whole circle board, passengers and train managers are chosen as the subjects that this group focused on since they are two main entities during the travel in railway. Their requirements will be showed explicitly in the tables. Subsequently, the functional decomposition for both passengers and managers will be analysed, respectively.

Table 1. Relevant Stakeholders of Standard Class Carriage of HS2
 

Train manager
As one of the most relevant stakeholder, train manager is the man who is in charge of each aspect within the whole train,makes decisions when facing some emergencies and also should have specific requirements for the train. The requirementsfrom train manager should include the easily understanding of information about the train as well as the passengers, which can be decomposed into four main requirements at level 2: a clear indication of door status, a immediate communication to train driver, ability to count the number of passengers in each carriage and accesses to each carriage. Furthermore, these functions can also be decomposed into sub functions at level 3, which is showed in Table 2.


2.2 Passengers
Passengers are definitely another most important stakeholders within this case. As the customers of the train service, passengers have full voice about the requirements for the whole train. Except the person-related factors, their main requirements are all facility related, which are most associated with the train manufacturer. Also, several sub-functions are mentioned as level 2, which has been listed in Table 3.


3. Physical decomposition物理分解

A number of physical specifications have been considered as the technical solutions to the sub functions for train managers as well as the passengers during the brainstorm within our team. The requirements of passengers are mostly本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
