DIN EN 15380-4:2013-05 EN 15380-4:2013 (E) 4 Introduction The Functional Breakdown Structure is used by all parties involved in the rolling stock pr
24、oduct definition phase and the following processes to structure the functional requirements and use cases according to a standardized list of functions. It starts with the concept and spreads across the whole product life cycle. During this period, the level of detail of the structure could be adapt
25、ed according to the project progress. This means that functions in a product concept catalogue mainly are described by requirements. The transfer into implementable hardware and software takes place later. The Product Breakdown Structure (PBS) shown in EN 15380-2 and the Functional Breakdown Structu
26、re (FBS) shown in EN 15380-4 complement each other. While the PBS, consisting of the standardized list of subsystems and devices, is used for structuring system requirements and related use cases, the FBS standard describes the functions of a vehicle and is used to obtain a correlation between funct
27、ional requirements and the structure of functions and the related use cases. These structures describe different views on the rolling stock product. The importance of the two structures may be different according to the users tasks as well the project stage (see also EN 15380-1:2006, Annex C). The F
28、BS can also be used for specifying tasks as well as for analysing tasks. The functional assessment supports the whole engineering process and the field of RAMS/LCC (Reliability, Availability, Maintainability, Safety/Life-Cycle Costs). Often during the project process RAMS/LCC values have to be given
29、 at a stage when insufficient information regarding the technical solution is available. (At this stage of a project, EN 15380-2 is not applicable.) In all cases in which functionality is a key issue (e.g. safety and reliability analyses, inspections and testing, maintenance programmes, field data a
30、cquisition and related documentation), communication is based on a functional vehicle structure composed of functional groups particularly when cross-system or interdisciplinary considerations are important. Functions are grouped into levels regardless of their vehicle specific technical realisation
31、. Hence the function groups and function descriptions were developed without considering how each function may be achieved in practice. This is consistent with the EN 81346 series. This also applies when the functional vehicle breakdown structure is met in tracing vehicle properties, for example dur
32、ing the validation phase. Many of the required properties fixed in the product concept catalogue are realised, diagnosed and rated as functioning or malfunctioning during operation. Only afterwards is the link made to the physical structure and then to the assessment of the function of technical sol
33、utions. There is not necessarily a simple one to one relationship between each function and its technical realisation. A system or item of equipment can contribute to different functions at the same time or in sequence. This means that an entity can be related to different functions and even from di
34、fferent levels (see Annex A). Assignment of examples for well known function carriers are given for easier understanding. DIN EN 15380-4:2013-05 EN 15380-4:2013 (E) 5 1 Scope This European Standard is concerned with the functions associated with general railway vehicles or their assemblies. It cover
35、s functionality associated with systems and equipment such as wheelsets and bogies, doors, brakes and traction. This standard may also be applied to railway vehicles with very specific functions like track machines and snow ploughs. However, while the functions that are common with general railway v
36、ehicles are included, the functions which are specific to their work processes are not included in this standard. They will 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 indispensable f

EN 15663, Railway applications Definition of vehicle reference masses 3 Terms and definitions For the purposes of this d
38、ocument, the following terms and definitions apply. 3.1 function specific purpose or objective to be accomplished, that can be specified or described without reference to the physical means of achieving it SOURCE: IEC 61226:2009 Note 1 to entry: A function transfers (considered as a black-box) input
39、 parameters (material, energy, information) into aim related output parameters (material, energy, information) performed by technical means and/or human beings. 3.2 transverse function sub function which may apply to more than one higher level function Note 1 to entry: For example, providing diagnos
40、tics or displaying information. 3.3 Functional Breakdown Structure (FBS) hierarchical structure summarising a set of functions leading to the same general focus or service Note 1 to entry: To define the level of a function within a FBS, see Clause 5. 3.4 function level level of group functions of eq
41、ual purpose Note 1 to entry: Assignment to the appropriate level is described in the rules. 3.4.1 1stlevel function functional domain or general focus or service for the considered (rolling stock) system DIN EN 15380-4:2013-05 EN 15380-4:2013 (E) 6 Note 1 to entry: In general, the first level functi
42、on encompasses a set of functions related to a same general focus or service for the considered (rolling stock) system. EXAMPLE Provide appropriate conditions to passengers, train crew and load. 3.4.2 2ndlevel function main function which contributes to complete the first level Note 1 to entry: In g
43、eneral, the 2ndlevel function encompasses a set of sub functions and contributes to the completion of the first level. Note 2 to entry: If the next level of the functional domain is not related to a main function there could be a direct relation to a lower level function. 3.4.3 3rdlevel function sub
44、 function which contributes to complete the 2ndlevel Note 1 to entry: In general, the 3rdlevel function encompasses a set level 4 functions (usually tasks) and contributes to the completion of the second level. Note 2 to entry: If the next level of the main function is not related to a sub function
45、there could be a direct relation to a lower level function. 3.4.4 4thlevel function function related to a task which contributes to complete the third level Note 1 to entry: In general, the 4thlevel function encompasses a set of level 5 functions (usually activities) and contributes to the completio
46、n of the third level. Note 2 to entry: If the next level of the sub function is not related to a task there could be a direct relation to lower level function (activity). 3.4.5 5thlevel function function related to an activity necessary for performing the 4thlevel function 3.5 requirement necessary
47、condition or ability to constrain the solutions of a task or an aim Note 1 to entry: A requirement describes for example, performance characteristics, operational conditions and quality attributes, expressed as measurable and testable technical parameters or indicators. Note 2 to entry: Requirements
48、 are usually summarised in a specification. Note 3 to entry: Beside requirements allocated to functions are additional requirements allocated to other features (e.g. design, manufacturing). 3.5.1 functional requirements specific need or capability of a FBS function Note 1 to entry: Functional requir
49、ements and use cases first come from passenger/payload and operator requests. Later in the engineering process, functional requirements from integrators and suppliers are added. They express the requirements on a certain functionality given in the FBS regarding interoperability (with other functions), safety, operation, function/behaviour, or functional architecture/design constraints. The functional designation is usually stated more precisely by detail properties (see also Annex D) that
