Railway applications - Guidance for the use of simulations - Guidance for the use of simulations to demonstrate compliance with technical and regulatory requirements and on the introduction and development of simulation requirements into standards
The aim of this document is to help CEN/CENELEC Working Group convenors and experts to promote/develop simulation in their standards as an alternative to physical tests on the real system for proving conformity. It can also provide useful guidance to assessors in the railway sector in approving simulations where they are not yet specifically defined or where physical tests on the real system are not defined in standards. Consequently, this document is also relevant to companies developing and applying simulations with the intention to achieve their acceptance for the purpose of system validation. It is not intended to provide technical guidance on applying simulations in general.
Where simulations are already introduced in existing standards, this guide is not intended to modify the specified requirements. However, technical harmonisation between standards might benefit from this guide for the introduction of additional alternative methods for simulations.
This document principally covers:
• Numerical simulation, using complex methods or using simple spreadsheets methods
• Hardware and software in the loop
• Mathematical models solved using numerical methods or iteration, including spreadsheets.
It does not cover the following, although the general principles outlined can be applied to these methods:
• Laboratory tests of components
• Fatigue rig tests
• Model scale tests
• Mathematical models solved analytically.
NOTE: Due to the limited experience in the railway sector in the application of data-based (as opposed to model-based) simulations, for example using artificial intelligence (AI), neural networks, big data, etc., this approach is not further developed at this stage in this document.

Železniške naprave - Navodilo za uporabo simulacij - Navodilo o uporabi simulacij za dokazovanje skladnosti s tehničnimi in regulativnimi zahtevami ter o vnašanju in razvoju simulacijskih zahtev v standarde
Namen tega dokumenta je pomagati vodjem in strokovnjakom delovne skupine CEN/CENELEC pri spodbujanju/razvoju simulacije v njihovih standardih kot alternativo fizičnim preskusom na dejanskem sistemu za dokazovanje skladnosti. Poleg tega ocenjevalcem v železniškem sektorju zagotavlja uporabne smernice pri odobritvi simulacij, kjer še niso posebej opredeljene ali kjer fizični preskusi na dejanskem sistemu niso opredeljeni v standardih. Posledično je ta dokument relevanten tudi za podjetja, ki razvijajo in uporabljajo simulacije z namenom, da bi dosegla njihovo sprejetje za namene sistemske validacije. Ta dokument ni namenjen zagotavljanju tehničnih navodil za uporabo simulacij na splošno.
Če so simulacije že uvedene v obstoječih standardih, ta navodila niso namenjena spreminjanju zahtev, ki so v njih določene. Ta navodila pa bi lahko bila koristna za tehnično usklajevanje med standardi za uvedbo dodatnih alternativnih metod za simulacije.
Ta dokument obravnava predvsem:
• numerično simulacijo z uporabo kompleksnih metod ali enostavnih metod, ki temeljijo na preglednicah;
• strojno opremo in programsko opremo v zanki;
• matematične modele, ki se rešujejo z uporabo numeričnih metod ali ponavljanja, vključno s preglednicami.
Ta dokument ne obravnava naslednjega, čeprav se lahko v njem opisana splošna načela uporabijo pri teh metodah:
• laboratorijski preskusi komponent;
• preskusi utrujenosti opreme;
• sorazmerno preskušanje modelov;
• matematični modeli, ki se rešujejo analitično.
OPOMBA: Zaradi omejenih izkušenj v železniškem sektorju pri uporabi simulacij, ki temeljijo na podatkih (v nasprotju s simulacijami, ki temeljijo na modelih), na primer z uporabo umetne inteligence (AI), nevronskih omrežij, masovnih podatkov itd., se ta pristop na tej stopnji v tem dokumentu ne razvija naprej.
