EN 15380-4:2013 (E) 4 Introduction The Functional Breakdown Structure is used by all parties involved in the rolling stock product 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 adapted 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 Structure (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 functional 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 FBS 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 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 acquisition 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. 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 during 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 solutions. 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 different levels (see Annex A). Assignment of examples for well known function carriers are given for easier understanding. SIST EN 15380-4:2014



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 covers 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 vehicles 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 for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 15663, Railway applications — Definition of vehicle reference masses 3 Terms and definitions For the purposes of this document, 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 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 diagnostics 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 equal purpose Note 1 to entry: Assignment to the appropriate level is described in the rules. 3.4.1 1st level function functional domain or general focus or service for the considered (rolling stock) system SIST EN 15380-4:2014



EN 15380-4:2013 (E) 6 Note 1 to entry: In general, the first level function 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 2nd level function main function which contributes to complete the first level Note 1 to entry: In general, the 2nd level 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 3rd level function sub function which contributes to complete the 2nd level Note 1 to entry: In general, the 3rd level 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 there could be a direct relation to a lower level function. 3.4.4 4th level function function related to a task which contributes to complete the third level Note 1 to entry: In general, the 4th level function encompasses a set of level 5 functions (usually activities) and contributes to the completion 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 5th level function function related to an activity necessary for performing the 4th level function 3.5 requirement necessary 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 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 requirements 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 provide more information referring to reliability, availability, performance, quality, documentation, input, output, realtime.
SIST EN 15380-4:2014



EN 15380-4:2013 (E) 7 These stated higher-level functional goals for ambient conditions, design features and selected target groups/target objects are “requirements to a function”. Note 2 to entry: In the FRS associated to a function at level 2 or below, the functional requirements met by the transverse functions are listed for each transverse function.
3.5.2 system requirement requirement on a subsystem or device
Note 1 to entry: Requirement on a subsystem or device regarding the requested technical capability, reliability, availability, maintainability, environmental impact/conditions (recyclables, emissions, EMC, climate, vibration), safety, LCC, performance, quality, documentation, realtime behaviour, physical limits (dimension, weight), electrical interface (plugs, voltage, physical layer), or mechanical interface (fixing points, fixing method). 3.6 scenario possible transient, unsteady or steady states of the regarded system or of system-user interaction including environmental or other influences Note 1 to entry: Operational and environmental conditions under which the system is intended to or actually functions. 3.7 use case summary of scenarios for a single task or goal from the view of an exterior observer under defined conditions 3.8 object (unit of observation) component, element, device, subsystem, functional unit, operating medium or system that can be observed in its own right [SOURCE: EN 15380-2:2006] 3.9 error deviation from the intended design which could result in unintended system behaviour or failure [SOURCE: EN 50129:2003] Note 1 to entry: An error needs corrective action. It is caused by defect component and can be displayed to the driver or workshop. An error can lead to a failure. Note 2 to entry: An error also is a discrepancy between a computed, observed or measured value or condition and the true, specified or theoretically correct value or condition, e.g. a computing error made by faulty computer equipment. 3.10 fault abnormal condition which could lead to an error in the system
Note 1 to entry: A fault can be random or systematic. [SOURCE: EN 50129:2003, modified] 3.11 failure deviation from the specified performance of a system [SOURCE: EN 50129:2003] Note 1 to entry: A failure also is a deviation from specified performance of a function. SIST EN 15380-4:2014



EN 15380-4:2013 (E) 8 Note 2 to entry: A failure may be the consequence of a fault or error in the system. 3.12 event occurrence of a state at a defined precondition and time 3.13 monitoring independent real-time observation of system, consist and train states (in cases also based on combinatory logic) for manual or automatic operation Note 1 to entry: Monitoring is often safety related, partly mission critical. 3.14 protocol event recorded event which is not the result of a fault, failure or error Note 1 to entry: A protocol event is often used to store driver actions. 3.15 alarm event requiring driver interaction, with a defined priority Note 1 to entry: The event may be generated by man or machine.

General remarks The hierarchy of the functional groups serves as a guideline when creating functional structures. Functions are realised at the technical level as hardware and software within hierarchically structured units. Although the units interact at the functional level, they may be spatially separated from one another. Expanding the functions, elementary functions and characteristic features 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.
Changing the existing functional levels shall be avoided.
Functional units can be associated with several functions. A single function can be distributed over several functional units. The FBS is organised in such a way that the whole driver interface functionality is described under HE "Allow proper control". This driver interface functionality does not contain any control functionality itself. It only provides information to the driver, including the status signals from other functionalities. 5.2
Classification system used for functions Functions are designated using letters of the alphabet only, as set out in Table 1, Table 2 and Table 3. The use of the letters I and O, as well as special characters and separators, have not been used. The first level functions, functions on lower levels and transverse functions are coded in their respective levels using a single letter. If transverse functions are applicable for each function several lines with related transverse function can be added in following way = AAAAA.TTT, AAAAA.TTT, where AAA is the identifier for FBS and TTT is the identifier for transverse function found in Table 3. If a transverse function is not used the identifier for FBS is = AAAAA. The classification systems can be used either in whole or in part. As a minimum it is recommended to use it from level 1 to level 5. SIST EN 15380-4:2014
