Executive Summary执行摘要
在这个任务中,介绍了测试系统的定义,和V型系统在工程领域的应用。采取内在因素(铁路系统类型,维修方式,机车运营,货运业务,乘客运营,车辆类型,铁路建设和永久方式)和外在因素(人文地理、自然地理、历史因素)考虑。1章介绍了V系统,包括定义、目标、验证,两个流,应用的优势和局限性。第二章,文献综述是关于线路规划、列车运行图、列车车辆进行重整,规划,人员规划。第3章介绍了控制器的模型。之后,在4章讨论的是内在因素和外在因素对铁路系统。在5章中,V型系统在铁路系统中的应用进行总结,对铁路系统的影响因素进行了分析。
In this
assignment, the definition of Vee system was introduced, and the applications of Vee systems in
Engineering area. Various factors like intrinsic factors (types of rail system, maintenance of way operations, locomotive operations, freight operations, passengers operation, types of vehicle, railroad construction and permanent way) and extrinsic factors (human geography, physical geography, historical factors) are taken into consideration. Chapter 1 introduced the Vee system, including the definition, objectives, verification, two streams, application, advantages and limits. In the second chapter, the
literature review was done about the line planning, train timetabling, train platforming, rolling stock planning, crew planning. In chapter 3, the model of controllers was introduced. After that, the intrinsic factors and extrinsic factorson the railway system was discussed in chapter 4. In chapter 5, the application of Vee system in railway system was concluded and the impact factors on the railway system was also discussed.

1. Introduction and Background
Vee process(Cerboneschi and Arimondo 1996) is defined as the lifecycle of systems development that is presented in the form of graphic. Principal steps that are relevant to the correspondent deliverables inside the framework of system validation that is computerized are taken into account.
The main steps within the development of project life cycle that has the specific sequence form the V shape(Fischer, Gill et al. 2001). The creation of specific systems and decomposition of requirements are represented by the left side of the V, while the validation and integration of parts are represented by the right side of the V. In addition, the relevant requirements must be validated according to the more strict requirements, Moreover, the system models could also be validated by other ways, which could also been completed partially within the left side of the V. So it is not so accurate to claim that the validation is constrained within the right side. To be simple, the validation depends on the user needs and real world, and the requirements part (i.e. technical issue) decides the verification part.
Sometimes this issue could be expressed as “do the right thing” and “do it right”. While when it comes to the realistic application, the terms used varies and even exchange with each other sometimes.
Validation is defined to make sure that the relevant stakeholders and customers are satisfied with the system, service and product. The suitability and acceptance are usually involved with the external customers.
On the other hand, verification is to evaluate whether the system, service, or product meets the imposed condition, specification, requirement, or regulation.
