+\section{Introduction} +Some safety documentation is available in the ERTMS documentation set, despite it has not been +updated for the Baseline 3. + +The SUBSET-88 provides system fault trees, and lists several FMEA documents for various parts +of the system. The SUBSET-91 summarize the leaves-events of the fault trees, and provides some safety +requirements. + +The goal of the current document is to go through some prototyping examples chosen in the document +\emph{SRS subset for modelling tool benchmarking} and to define on these examples how the Safety +Requirement could be extracted from the ERTMS documentation downto the model level, and what +formalism could be used in order to express them. + +Please, note that the purpose of the models provided herebelow is not to be completely ``formal''. +It is only to be sufficiently formal in order to convince oneself that it will be possible to express +executable models and safety properties, and to outline the process followed in order to provide these. + +The formalism used for the model is state machines with actions and variables. As for the safety +properties it is a simple propositional calculus which specific predicates to handle transitions +and states of the model\,\footnote{This is sufficient for the examples in this document, but it +will probably not be the case for the whole OpenETCS project.}. + +Please also note that the process followed is described in an ``intuitive'' way, in order to make +it easily understandable and to show the different options. This document is not meant to describe +the Safety Analysis process in a formal way, this should be the purpose of the Safety Plan (WP4). The +process describe here should only be considered as ``one possible solution''. + +\section{Reference documents} +\begin{itemize} +\item WP2/D01 --- \emph{SRS subset for modelling tool benchmarking} +\item SUBSET-026 3.3.0 --- \emph{System Requirement Specification} +\item SUBSET-081 2.3.0 --- \emph{Transmission System: Failure modes and effects analysis} +\item SUBSET-088 2.3.0 --- \emph{ETCS Application Levels 1 \& 2 - Safety Analysis} +\item SUBSET-091 2.5.0 --- \emph{Safety Requirements for the Technical Interoperability +of ETCS in Levels 1 \& 2} +\end{itemize} + +\section{Example 1: Establishing a communication session} +In this example, we try to model the requirements in the 3.5.3 section of the SRS SUBSET 26, +for Level 2/3. + +The whole purpose of the function is to establish a communication either from the OBU, or from the +RBC. For the sake of simplicity, we will only cover the case where the communication is initiated by +the OBU. + +\subsection{Safety Properties from UNISIG documents} +\label{safety_top} +The processus of identification of the safety properties is a twin process of the processus of +defining the system and subsystems. + +Once the overall system is defined, the first step for the safety analysis should be to identify +which are the Safety Properties laying +on the objects that will be studied and modelled. Usually, in order to defined these Properties, +it is necessary to start at a very high level by the Preliminary Hazard Analysis (PHA) which states the +system Dread Events for the overall system. These events are very high level: for example we could +find electrocution, or head-on collision. + +The overall system should then be split into different subsystem with different area of responsibilities +(for example onboard subsystem, interlocking, driver\dots) + +The system-level Dread Events must now be allocated to the different subsystems according to the system +architecture, and refined to +match the subsystem boundaries and area of responsibilities. This can be done using +Fault Tree\,\footnote{We will call them Fault Trees even if all events in the trees will not necessarily +be Faults and Failures but could be random or sparse events.} Analysis. + +In the case of ERTMS, SUBSET-88 provides such Fault Trees. Fig. \ref{fig:ch_fault_tree} describes for +example the events leading to the Dread Event ``Brake Control Function Failure\,\footnote{Event +if this does not go up to the main system Dread Events, one can easily imagine how this +could cause a collision}''. The main event is then refined to leaves or other sub-Fault Trees, +in particular the Tree identified by GATE80, corresponding to an incorrect determination of the +current mode. + +This mid-level event is then also refined (Fig. \ref{fig:mode_fault_tree}) to events and especially +leaves that are expected to be of the SRS level. This leads in particular to the lower-level events +KERNEL-3 to KERNEL-6 (see Fig. \ref{fig:mode_fault_tree} or \ref{tab:kernel_evt}) which are related +to the radio transmission. These lower level events are +summarized into the SUBSET-91 document, which is a mandatory part of the ERTMS documentation. + +\begin{figure} + \centering + {For IPR reason, the figure was removed. \\ + The reader shoud refer to SUBSET-88-2 Part 1, Appendix B, p. 2} + \caption{Core Hazard Fault Tree (SUBSET-88)} + \label{fig:ch_fault_tree} +\end{figure} + +\begin{figure} + \centering + {For IPR reason, the figure was removed. \\ + The reader shoud refer to SUBSET-88-2 Part 1, Appendix B, p. 8} + \caption{Incorrect Mode Fault Tree (SUBSET-88)} + \label{fig:mode_fault_tree} +\end{figure} + +\begin{issue} +Should the Fault Trees Analysis provided in the SUBSET-88 be considered as complete? My feeling is +that it is not the case, because there is no ERTMS Safety Plan (AFAIK) to track the way the analysis +was conducted, so there is no proof that the analysis is sufficiently rigorous. + +Moreover, we'll see in Sect. \ref{gaps} that the trees should be refined again before being at the proper +level. +\end{issue} + +It is now necessary to analyze if each scenario is covered and how (and if the coverage is sufficient). +We will call ``scenario'' the succession of events needed to provoke a studied Dread Event (which could +be high- or low-level). Covering the scenario could be done by proving that a requested leaf is always +impossible to meet, or by proving that the conjunction of all the requested sub-events would be rarer +than the THR (Tolerable Hazard Rate) requested for ERTMS application or its allocation to the studied +sub-system. + +%\begin{sidewaysfigure} +\begin{figure} + \centering + {For IPR reason, the figure was removed. \\ + The reader shoud refer to SUBSET-88-2 Part 2, p. 23-24} + \caption{Kernel Dread Events (as in SUBSET-88 or SUBSET-91)} +\label{tab:kernel_evt} +\end{figure} +%\end{sidewaysfigure} + +SUBSET-88 provides the following informations on the events that interest us +(cf. Fig. \ref{tab:kernel_evt}). This table lists the base events (leaves) of the tree +and describes the impact of such events, and the mitigation used to avoid safety problems. +The problem is that whether there is a safety issue is not made that explicit: if we take +KERNEL-6, for example, the description states that a loss of communication could lead either to a +failure to receive more restrictive route information, or to the driver being obliged to use a lower +level. We can imagine that these are not catastrophic consequences (we wouldn't risk the safety on +the probability that a message does not reach its destination), but in order to make this statement, +it needs a system-level analysis. + +Nevertheless, in this case the third part of SUBSET-88 (9.3.3.1) provides an answer \footnote{ +The same explanation may be found also in SUBSET-91.}: +\begin{quote} +As indicated in 9.2.2.1, the data exchange between track and train is defined in the +ETCS specifications such that normally the deletion of a message does not result in a +hazard. Moreover, deletion of critical messages is mitigated by means of +acknowledgement procedures. The only case where deletion may lead to a hazardous +situation is in the case of Emergency messages and this situation is considered in the +following section.

A process to be used in order to find out these events could be +to build a system FMECA starting from the formal model. +\begin{itemize} +\item Not being able to establish a communication while required; +\item Establishing a communication while not required; +\item Establishing a communication with the wrong RBC; +\item Establishing a communication with an incompatible version RBC; +\item \dots ? +\end{itemize} + +Considering the events studied in Sect. \ref{safety_top}, we can state that the first item does +not lead to an unsafe state. It will not yield a safety property. As for the second, the safety status +is not as clear. It is necessary to conduct a system safety analysis in order to decide if failure +leads to an unsafe state, and in this cas to state a property to cover this event +(for the sake of brevity, we will not do it in this document). As for the third event, we will consider +it as unsafe, because if we cannot guarantee that the same RBC is used during the whole process, it is +unlikely that we will be able to perform the version control requested to cover the lattest issue. +The last failure (establishing a communication with an incompatible version +RBC) could clearly lead to an unsafe state, if possible (although a system-level analysis should +confirm this). + +Assuming these are all the safety event we have to cover, we could therefore provide the following +property in order to cover them. This property is somehow redundant with the model, but it is restricted +to the bare safety need. +$$State = Established \Rightarrow compat(V\_Com)\wedge RBC\_ID = RBC\_Com$$ + +\subsection{Filling the gaps\dots} +\label{gaps} +If we compare the events provided by the Fault Trees (KERNEL-\emph{xx}) it is clear that they are +still too high level to be able to be used to build directly the safety properties on the studied +function. These properties are still high level compared to the degree of description in the SRS. This +is due to the fact that these events are \emph{functional} although the function studied (establishing +a communication) is a rather low level service. + +The question is ``would it be possible to go \emph{formally} from the high level Dread Events to +the properties which goes on the same level than the model?'' In my opinion this is not practically +feasible. It would need a very high level model of the system (much higher than the SRS) without any +allocation to the different subsystem. It would also be necessary to introduce a sufficiently wide +notion of environment to be able to formalize that communicating with an improper version of software +could lead to an unsafe behavior. + +\begin{figure} + \centering + \fbox{\includegraphics[scale=0.40]{ext_fta.pdf}} + \caption{Extending the Fault Tree} + \label{fig:ext_fta} +\end{figure} + +It is therefore necessary to conduct a system-level ``brain, paper and pen'' safety analysis to +be able to build the safety properties on the proper level with regard to a model of the SRS. This +analysis could be carried out either with a \emph{top-down} analysis (cf. Fig. \ref{fig:ext_fta}) or +by a \emph{bottom-up} analysis (\emph{e.g.} FMECA), or by combining both approaches. It is important +to point out that whichever is the followed method, it is the level of expertise of the safety analyst +above everything else that will guarantee that no unsafe case have been forgotten. + +\section{Example 2: Mode Transitions} +The purpose is to modelize some of the mode transitions of the SUBSET-26 4.6.2 table (mode transitions), +namely the transitions from SB to SH, FS and IS. + +\subsection{Model of the function} +The model here is very simple (Fig. \ref{fig:trans_sb_tab} and \ref{fig:trans_sb} ) +because we do not want to dive into the condition details. + +\begin{figure} +\centering +\small +\begin{tabular}{|l|l||p{3.5cm}|p{3.5cm}|} +\hline +\bf From & \bf To & \bf Condition & \bf Action \\ +\hline +SB & IS & Isolated & \\ +\hline +SB & FS & FS conditions and not Isolated & \\ +\hline +SB & SH & SH conditions and not Isolated & \\ +\hline +\end{tabular} +\normalsize +\caption{Mode transitions from SB to SH, FS and IS (transitions)} +\label{fig:trans_sb_tab} +\end{figure} + +\begin{figure} + \centering + % dot trans_sb.dot -Teps -o trans_sb.eps && epspdf trans_sb.eps + \fbox{\includegraphics[scale=0.70]{trans_sb.pdf}} + \caption{Mode transitions from SB to SH, FS and IS} + \label{fig:trans_sb} +\end{figure} + +\subsection{Safety properties} +As for the safety properties, the SUBSET-88 provides the following event. +\begin{center} +GATE80: Incorrect determination of the current mode +\end{center} +Without a clear hierarchy of modes stating that being in one given mode instead of other ones, we +shall consider that as far as safety is concerned, a transition must occur if and only if the +corresponding conditions are verified at the time of the transition. + +We do not want to define here a complicated formalism. We use simple predicates +$State(X)$ to write that the machine is in the state $X$, and $A\rightarrow B$ that the machine triggers +a transition from state $A$ to state $B$. The important thing here is that we are introducing some +dynamic behavior (although we keep on using proposition calculus). + +% $$SB\rightarrow IS \iff Isolated\_by\_Driver \wedge State(SB)$$ +% $$SB\rightarrow FS \iff FS\_Conditions \wedge \neg Isolated \wedge State(SB)$$ +% $$SB\rightarrow SH \iff SH\_Conditions \wedge \neg Isolated \wedge State(SB)$$ + +$$SB\rightarrow IS \implies Isolated\_by\_Driver$$ +$$Isolated\_by\_Driver \wedge State(SB) \implies SB\rightarrow IS$$ +$$SB\rightarrow FS \implies FS\_Conditions \wedge \neg Isolated$$ +$$FS\_Conditions \wedge \neg Isolated \wedge State(SB) \implies SB\rightarrow FS$$ +$$SB\rightarrow SH \implies SH\_Conditions \wedge \neg Isolated$$ +$$SH\_Conditions \wedge \neg Isolated \wedge State(SB) \implies SB\rightarrow SH $$ + +These properties are a bit disappointing, because they are a mere paraphrasing of the state machine +provided in the model. We could try to go a little bit further with a system-level analysis of the +SUBSET-26 mode transition table. We would like to provide in the safety properties the conditions +which are really relevant to safety (but these might as well be \emph{all}). + +For this task we need to consider the transition out of the states. +For the sake of brevity, we consider only the four modes IS, FS, SB and SH (but we use the full sub-state +machine of the real ETCS mode with these modes) and do not discriminate here the different Shunting +conditions depending of if the initial state is FS or SB (Fig. \ref{fig:trans_whole} and \ref{fig:trans_whole}). + +\begin{figure} + \centering +\small +\begin{tabular}{|l|l||p{3.5cm}|p{3.5cm}|} +\hline +\bf From & \bf To & \bf Condition & \bf Action \\ +\hline +SB & IS & Isolated & \\ +\hline +SH & IS & Isolated & \\ +\hline +FS & IS & Isolated & \\ +\hline +SB & FS & FS conditions and not Isolated & \\ +\hline +SB & SH & SH conditions and not Isolated & \\ +\hline +SH & SB & Exit SH conditions and not Isolated & \\ +\hline +FS & SB & Exit FS conditions and not Isolated & \\ +\hline +FS & SH & SH conditions and not Isolated & \\ +\hline +\end{tabular} +\normalsize +\caption{Mode transitions with states SB to SH, FS and IS (transitions)} +\label{fig:trans_whole_tab} +\end{figure} + +\begin{figure} + \centering + % dot trans_whole.dot -Teps -o trans_whole.eps && epspdf trans_whole.eps + \fbox{\includegraphics[scale=0.70]{trans_whole.pdf}} + \caption{Mode transitions with states SB to SH, FS and IS} + \label{fig:trans_whole} +\end{figure} + +From the initial set of properties, it seems difficult to be able to remove some. We could add new ones, +but it would need to be interesting from a system standpoint. For example we might want to prove that +the OBU is \emph{never} in isolated mode if not requested by the driver. We could write this as: + +$$(SB\rightarrow IS) \lor (SH\rightarrow IS) \lor (FS\rightarrow IS) \implies Isolated\_by\_Driver$$ + +We could also state that the IS state is a ``dead'' state (state with no exits). This provides the +following, for the subset of modes provided here. + +$$\lnot((IS \rightarrow FS) \lor (IS \rightarrow SB) \lor (IS \rightarrow SH))$$ + +This is of course redundant with the previous properties the state machine, but it provides a +simple and understandable safety property that cover exactly the safety need. + +We could try to do the same for the other modes, but it will be the same problem. Most of the safety +behavior is yielded by the model itself and it is difficult to produce a set of +declarative properties, and to avoid paraphrase. Nevertheless, it is useful to point out some specific +and important system properties, even if they are not sufficient to capture the whole behavior of +the state machine. In this case, these properties must come on top of the mere rephrase of the model. + +Of course, it would also be possible to switch to a ```bigger scale'' view, and state properties +directly from the transition conditions to the behaviors allowed in the mode, but these properties +would probably be difficult to prove without the intermediate layer provided by the modes themselves. +And as far as modularity is considered, the properties and proofs would be difficult to maintain in +case of evolution of the system. + + +\section{Conclusion} +The two examples studied (establishment of the communication and mode transitions) are not exhaustive +in order to determine what would be the best formal language for safety properties (for this purpose +it would be useful to study also the braking curves and the MA), but they are sufficient to outline +the upper part (or ``system'' part) of the process that would be necessary in order to prove safety +in the context of OpenETCS: it starts by determining what is Vital and Non Vital, and by going down +from the higher level safety properties to the model level safety properties. A synthetic view of the +process is presented on Fig. \ref{fig:saf_process} + +On these two examples, we have seen that in some cases, it only needs a few safety properties to capture +the full safety behavior of the function, while in other cases, the full state machine (or a rephrase of +it) is necessary. We have also seen than in the latter, it can also be useful to provide safety +properties to express a particularly interesting (or sensitive) point. + +In both case, the safety properties provide the backbone of the safety analysis. Writing them down +allow to enhance knowledge and comprehension of the system, and they may also be used as Proof +Obligations, as assertion to check when the model is running, or even in order to provide help in the +generation (manual or automatic) of test cases. + +\begin{figure} + \centering + \fbox{\includegraphics[scale=0.50]{process.pdf}} + \caption{Outline of the safety analysis process} + \label{fig:saf_process} +\end{figure} + +\end{document} \ No newline at end of file diff --git a/Workspace/SafetyRequirementsExamples/template/ccbysa.png b/Workspace/SafetyRequirementsExamples/template/ccbysa.png new file mode 100755 index 0000000..8386b1b Binary files /dev/null and b/Workspace/SafetyRequirementsExamples/template/ccbysa.png differ diff --git a/Workspace/SafetyRequirementsExamples/template/ccbysabig.png b/Workspace/SafetyRequirementsExamples/template/ccbysabig.png new file mode 100755 index 0000000..8770732 Binary files /dev/null and b/Workspace/SafetyRequirementsExamples/template/ccbysabig.png differ diff --git a/Workspace/SafetyRequirementsExamples/template/chart.png b/Workspace/SafetyRequirementsExamples/template/chart.png new file mode 100755 index 0000000..a59f2f7 Binary files /dev/null and b/Workspace/SafetyRequirementsExamples/template/chart.png differ diff --git a/Workspace/SafetyRequirementsExamples/template/itea.jpg b/Workspace/SafetyRequirementsExamples/template/itea.jpg new file mode 100755 index 0000000..62acb73 Binary files /dev/null and b/Workspace/SafetyRequirementsExamples/template/itea.jpg differ diff --git a/Workspace/SafetyRequirementsExamples/template/openetcs_article.cls b/Workspace/SafetyRequirementsExamples/template/openetcs_article.cls new file mode 100755 index 0000000..59e9767 --- /dev/null +++ b/Workspace/SafetyRequirementsExamples/template/openetcs_article.cls @@ -0,0 +1,540 @@ +%% This is openetcs.cls +%% A LaTeX class based on: + + + +%% For openETCS ITEA2 Project + + +% +\NeedsTeXFormat{LaTeX2e} +\ProvidesClass{openetcs} +[2012/10/11 v0.1 Typesetting Technical Information Article of +openETCS project ] +\newcommand{\IsLicensedUnderCC}[1]{#1} +\DeclareOption{nocc}{\renewcommand{\IsLicensedUnderCC}[1]{ }} +\DeclareOption*{\PassOptionsToClass{\CurrentOption}{article}} +\ProcessOptions\relax +\LoadClass[11pt,twoside]{article} +\RequirePackage{graphicx,color,caption,longtable} +\RequirePackage{dcolumn} +\RequirePackage{natbib} +\renewcommand{\bibfont}{\fontsize{10pt}{12pt}\selectfont} +\setlength{\bibhang}{0.5in} +\setlength{\bibsep}{12pt} +\RequirePackage{amsmath} +\RequirePackage{microtype} +\RequirePackage[utf8x]{inputenc} +\normalsize + +% PdfLaTeX Choix 1 "times Helvet et math" http://www.cuk.ch/articles/4237 +\usepackage[T1]{fontenc} +\usepackage{txfonts} + + +\def\@projectfont{% + \sffamily\itshape\bfseries\fontsize{22pt}{25pt}\selectfont} +\def\@reportnumfont{% + \sffamily\bfseries\fontsize{18pt}{22pt}\selectfont} +\def\@wpfont{% + \sffamily\fontseries{k}\itshape\normalsize\selectfont} +\def\@titlefont{% + \sffamily\fontseries{h}\fontsize{20pt}{25pt}\selectfont} +\def\@distributionfont{% + \sffamily\fontseries{k}\fontsize{9pt}{11pt}\selectfont} +\def\@eqtagfont{\sffamily\bfseries\footnotesize} +\RequirePackage[a4paper, top=1in, bottom=0.7in, + left=1.25in, right=1.25in]{geometry} +\setlength{\parindent}{0pt} +\setlength{\parskip}{\baselineskip} +\setlength\labelwidth{1em} +\setlength\leftmargini\z@ +\addtolength\leftmargini\labelwidth +\addtolength\leftmargini\labelsep +\def\itemize{% + \ifnum \@itemdepth >\thr@@\@toodeep\else + \advance\@itemdepth\@ne + \edef\@itemitem{labelitem\romannumeral\the\@itemdepth}% + \expandafter + \list + \csname\@itemitem\endcsname + {\def\makelabel##1{##1}}% + \fi} +\def\enumerate{% + \ifnum \@enumdepth >\thr@@\@toodeep\else + \advance\@enumdepth\@ne + \edef\@enumctr{enum\romannumeral\the\@enumdepth}% + \expandafter + \list + \csname label\@enumctr\endcsname + {\usecounter\@enumctr\def\makelabel##1{##1}}% + \fi} +\widowpenalty=10000 +\clubpenalty=10000 +\raggedbottom +\RequirePackage{fancyhdr} +\renewcommand{\headrulewidth}{0.5pt} +\renewcommand{\footrulewidth}{0pt} +\fancyhfoffset{35pt} +\pagestyle{fancy} +\lhead{\textsf{\textbf{\footnotesize\@reportnum}}} +\rhead{\textsf{\textbf{\footnotesize\thepage}}} +\chead{} +\lfoot{} +\cfoot{\color{blue}\textsf{\textbf{\textit{openETCS}}}\color{black}\IsLicensedUnderCC{ -
