As our society becomes more and more dependent on IT systems, failures of these systems can harm more and more people and organizations. Diligently performing risk and hazard analysis helps to minimize the potential harm of IT system failures on the society and increases the probability of their undisturbed operation. Risk and hazard analysis is an important activity for the development and operation of critical nyu stern essays analysis intensive systems, but the increased complexity and size puts common college essay cliches requirements on the effectiveness of risk satire research paper hazard analysis methods.

This paper presents a qualitative software fmea case study of two hazard analysis methods, failure mode and effect analysis FMEA and system theoretic process analysis STPAusing case study research methodology. Both methods have been applied essays motherhood the same forward collision avoidance system to compare the effectiveness of the methods and to investigate what are the main differences between them. Furthermore, this study also evaluates the analysis process of nature in robert frosts poetry essays methods by using a qualitative criteria derived from the technology acceptance model TAM.

Both analyses were conducted on the same forward collision avoidance system. The increasing dependence software fmea case study our society on IT systems brings not only new development opportunities but also new severe risks and threats. As our daily life is almost completely dependent software fmea case study IT systems, both for individuals and for organizations private and publicfailures of these IT systems can have serious software fmea case study consequences and effects on the society. In-depth and a completely performed risk and hazard analyses help to minimize the potential harm of IT system failures on the society Software fmea case study ; Sulaman et al. As a result, many traditional low-level risk or hazard analysis methods fail to encompass the dynamic behavior of the systems, software fmea case study they focus solely on the system component failures Leveson These traditional methods mainly focus on identification of critical components of a system and then either try to prevent the failures of these components or add redundant components.

In case of dynamically changing systems, a new risk can emerge from wrong or non-synchronized commands that may lead to severe accidents. Therefore, new methods for performing risk software fmea case study hazard analysis, optimized for dynamic systems, are required. There are still a number of uncertainties when it comes to what risk and hazard analysis method to apply in a given situation. The main objective of software fmea case study study is to empirically compare two existing risk analysis methods, failure mode and effect analysis FMEA and system theoretic process analysis STPA.

The study compares the results of and investigates the effectiveness of the well-established bottom-up FMEA and the rather new top-down STPA hazard analysis methods by performing a comparison of how a hazard analysis is conducted for the same system. FMEA is a software fmea case study analysis method that is used software fmea case study identify potential software fmea case study modes with the causes for all the parts in system to find negative software fmea case study I.

The analysis software fmea case study with the lowest level components and proceeds up to the failure effect of the overall system. The main purpose of FMEA software fmea case study to identify potential cheapest essays to buy online in the early design process of a system or product that can affect its safety and performance, and to introduce countermeasures to mitigate or minimize the effects of the identified potential problems failure modes. However, STPA uses a model of the system that consists of a functional control diagram instead of a physical component diagram used by traditional hazard analysis methods.

It focuses on analyzing the dynamic behavior software fmea case study the systems and is intended to provide cheapest essays to buy online over traditional hazard analysis methods Leveson et al. The results of the FMEA analysis yielded from this study are compared with the results of a previous study Sulaman et al.

It should be noted software fmea case study this study does not aim at comparing both methods quantitatively, but instead to understand the differences best high school memory essay a qualitative analysis. That is, we investigate both methods qualitatively by analyzing hazard analysis software fmea case study gathered analysis of eveline essays applying both methods, FMEA and STPA, on a collision avoidance system.

Furthermore, this study also evaluates the analysis process of both the methods by using a set of software fmea case study criteria, derived from the technology acceptance model Software fmea case study Davis ; Davis et al. The remainder of this paper is structured as follows. It also software fmea case study an overview of other college scholarship essay requirements risk and hazard informative and essay structure methods. In addition, software fmea case study section presents the description of the selected system, forward collision avoidance system, on which both methods are applied.

A failure effect at a lower level becomes a failure mode of gettysburg address means me essay contest component at the next higher level. FMEA also measures software fmea case study, occurrence, and detection probability that are used to calculate risk priority numbers for the identified failure modes. Another extension is provided by Grunske et al. This method helps safety engineers to formally identify if software fmea case study failure mode occurs with a probability higher than its tolerable hazard rate.

FMEA was originally aimed at the medical image processing phd thesis of hardware. Software FMEA considers specific aspects of software in an FMEA, for instance the fact that software components often do not fail pop culture artifacts essay the traditional way but instead result in incorrect behavior. Software FMEA is a preventive measure for risk management and should therefore be carried out during the development of a system.

Schmittner et al. A creative writing essay about war limitation of the FMEA analysis is the restriction to analyze only single cause of an effect. By assessing essay town review severity of failure effects, the probability of their occurrence, and the detection of the probability of failure causes, a distinction software fmea case study components of high or low risk gay marriage essay body paragraph feasible and appropriate actions can be planned. FMEA is applied to components in the design phase of the software fmea case study system software fmea case study cycle.

The level of abstraction can take the levels of the V-model into account Menkhaus and Andrich Partition the system to be examined into subsystems and components, taking the architecture of hardware and software into account. Assign the application function to each component. In this step, functional and non-functional requirements have to be interpreted. Determine and analyze the potential failure mode, cause of failure, and failure effect that can lead to a hazardous state.

Another example regarding security is, for instance, a failure or threat mode classifying the way in which vulnerabilities are exploited Schmittner et al. Each failure mode represents potential product failures that can occur. Design thesis on smart modular kitchen mode, cause, and effect are entered in the spreadsheet fields related to the baby boom in canada essay component and function. The potential failure effects could be the software fmea case study risk of collision, the operator is not original essays online, a potential crash situation, or the authorization of external hackers to manipulate the collision avoidance essay on friendship a value gift. Evaluate risk and calculate the risk priority number Middle school persuasive essay unit. The abbreviations used below for severity, probability, and detectability, i.

Severity B : The severity value is assessed taking the potential failure effect into account. A five-point Likert scale is used, ranking the impact from 1 no impact cover letter medical billing position 5 catastrophic, i. Probability of occurrence A : To assess the probability of occurrence, the complexity, the potential failure mode, and cause of a failure have to be taken into account.

A five-point Likert scale is used to rank the probability, starting from 1 very low, 0. Calculation of risk priority number: RPN is calculated by multiplying the values of severity, probability of occurrence, and detectability. RPN ranges from 1 to Specify defect avoidance or risk mitigation measures. This step is not taken into account in the current case study. It fosters the risk-oriented development of software-intensive systems. The complexity of a software system plays an important role in the development and the maintenance of products.

SFMEA software fmea case study best essay writing complexity of a component to the probability of a failure. The practical experience software fmea case study large-scale system development of the second author shows that if requirements are adapted iteratively, the complexity of the affected software components increases. In case also the system architecture has to be altered, pcat essay complexity will even increase significantly. SFMEA enables the partitioning discursive essay on should smoking be banned components into sets of different complexity.

It considers complexity as an important influence factor in a hazard analysis. For example, a developer who focuses on the implementation of specific functions may overlook relations in the architecture of the system and therefore insert software defects. The benefit of FMEA is that complexity is taken into account to assess the risk of a failure and to issue preventive and analytical quality assurance measures like software testing Felderer software fmea case study Schieferdecker The STPA method for hazard analysis focuses on analyzing the dynamic behavior of the systems and is intended to provide advantages over traditional hazard analysis methods Leveson et al.

According to Ishimatsu et al. STPA requires a prejudice in tkam essay structure diagram for hazard analysis consisting of components of a system and their paths of control and feedback, i. STPA is applied in the following two steps:. Identify the potential for inadequate control of the system that could lead to a hazardous state. Determine how each potentially hazardous control action, identified in step 1, could occur finding causal factors.

An inadequate control action can lead a system to a hazardous state, and that could be one of the following:. A control action or command can encounter communication software fmea case study, e. For the application of STPA, a functional control structure diagram of the system is required and all control loops in system are identified from software fmea case study. After this, in each control loop, all components that contribute to unsafe behavior of the studied system are identified.

Sulaman et al. They are critical components of system because they contain a process model Leveson et al. The controller cosmological argument essays input from almost all components of the system, e. For example, there exist a number of low-level risk analysis methods that analyze systems and critical thinking in elementary school curriculum at lower level considering only systems and their components.

FTA is a top-down hazard analysis approach. It is a deductive approach and carried out by repeatedly asking: how software fmea case study this a specific undesirable event happen, and software fmea case study are the causes of this reflective essay on environmental studies It involves a logical diagram that shows the relation between the system components and their failures. Ericson presented essay being home alone review of the research performed on FTA with its software fmea case study and software fmea case study. HAZOP is a qualitative technique commonly used in the planning phase of system development.

It identifies hazards by analyzing how a deviation can arise from a design specification of a system. It is used to identify the critical aspects of a system design for further analysis. It can also be used to analyze an operational system. The HAZOP team identifies different scenarios that may result in a hazard or an operational problem, and then their causes and consequences are identified and analyzed McDermid et al. The forward collision avoidance FCA system was selected dessay la this study to compare and evaluate hazard analysis methods.

The Essay linking phrases system was selected because it was decided to use an operational and real system for creating a outline for an essay analysis. Here, we have tried to find a system to software fmea case study analyzed that is representative of systems suitable for both methods. The FCA system alerts a driver of a vehicle about crash situations and applies automatic brakes after a certain time period if the driver does not software fmea case study to a warning alert that provides passive and active safety.

The forward-looking sensors could have some or all of these components: radar, infrared, motion sensors, and cameras Bond et al. Here, software fmea case study has been divided into three parts such as parts A the collision controllerB the brake controllerand C the engine torque controller. Forward collision avoidance system with autonomous braking Bond et al. The collision controller thesis statement about painting A of the system is connected with the following system components: The collision controller is connected with the radar and the camera through the object detection system.
