18、:2014 (E) 4 Introduction The System Breakdown Structure (SBS) provides the means of defining a railway vehicle in manageable and recognizable main systems and subsystems. In addition to main systems and subsystems this document includes transverse elements, which result from the architectural design
19、. The SBS can be used to link functions according to EN 15380-4 to main systems and subsystems. The SBS is also used to associate subsystems with products. Examples of products or product groups are given in EN 15380-2. The relationships of functions to the SBS and to the products depend on the arch
20、itectural design of the railway vehicles. As a result of the architectural design there will be different associations of products to subsystems. These different associations can be compared and evaluated. In addition the SBS provides a common stable structure “black box approach” for optimization o
21、f the train architecture. The SBS with the other breakdown structures can be used at different stages of the vehicles life cycle. The SBS provides a common structure to be used by various stakeholders, e.g. authorities, operators, maintainers, integrators and suppliers. The System Breakdown Structur
22、e according to EN 15380-5 (SBS), the Product Breakdown Structure according to EN 15380-2 (PBS) and the Functional Breakdown Structure according to EN 15380-4 (FBS) complement each other. These structures describe different views of railway vehicles. BS EN 15380-5:2014EN 15380-5:2014 (E) 5 1 Scope Th
23、is European Standard defines the System Breakdown Structure for railway vehicles and their principal associated attributes. This European Standard may also be applied to specific railway vehicles like track machines and snow ploughs. However, while the systems that are common with general railway ve
24、hicles are included, the systems which are specific to their work processes are not included in this European Standard. They need to be added for these individual projects. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indisp

43、 Breakdown Structure (SBS) 5.1 General remarks The hierarchy of the SBS serves as a guideline when creating system structures. Systems realize functions at a high technical level as hardware and software within hierarchically structured units. Although the units interact at the functional level, the
44、y may be spatially separate from one another. Expanding the systems and subsystems is possible within the scope of this standard. Whether it is necessary to make use of this option will depend on the specific application being considered. Changes of the existing set of main systems and subsystems as
45、 defined in this standard shall not be permitted. BS EN 15380-5:2014EN 15380-5:2014 (E) 8 In the case the design solution requires transverse elements (see 3.11) the specific system breakdown structure comprises the system breakdown structure according to EN 15380-5 (SBS) expanded by the transverse
46、elements. 5.2 Classification used for system levels System levels are identified by using letters of the alphabet only, as set out in Table 1 and Table 2. The use of the letters I and O, as well as special characters and separators, is not permitted. The 1st level systems and 2nd level systems and t
47、ransverse elements are coded in their respective levels using a single letter. If transverse elements are applicable for each system, several lines with related transverse elements can be added in the following way, e.g. = = GA/V,GA/S, where GA is the identifier for SBS and V, S are the identifiers
48、for the transverse element contained in 5.4, Table 3. If no transverse element is used the identification in this example is = = GA. The classification systems can be used either in whole or in part. As a minimum, it is recommended to use it with both level 1 and level 2. Key 1 sign system“ accordin
