Common Sense on Reliability Engineering
(Part 2 of 3)

“Unfortunately, the development of quality and reliability engineering has been afflicted with more nonsense than any other branch of engineering.” - Patrick O’Connor

In the first part of this series, it was argued that Reliability is the absence of failures in products and systems. Furthermore, Reliability Engineering can be defined as the management function that prevents the creation of failures by people (such as systems engineers, design engineers, production personnel, users and maintenance personnel).

The ideal state of “absence of failures” can only be achieved in practice by preventing failures from occurring in the first place. However, the prevention of failure is only possible if we (preferably during design and development) develop a thorough understanding of potential failure modes, and then take appropriate steps to prevent them from occurring. This understanding of potential failure modes is obtained by using “Analysis” and “Test” as design and production verification methods as indicated in Figure 1.

What is meant by “Analysis” in this context?

1 Design analysis

Many development activities involve both “design” and “analysis” aspects, which can be totally integrated or not, and which are typically iterative in nature. For example, an electronics engineer may select a certain circuit configuration, and then simulate (i.e. analyse) the chosen circuit to verify intended operation. In most cases, these circuit design tools can also be used to develop an understanding of potential product failure modes. In this example, the designer may include component tolerances, expected operating temperature and parameter drift with the nominal values in the simulation model and evaluate the design under worst case conditions (e.g. using Monte Carlo simulation).

Figure 2 shows the results of a worst case Monte Carlo simulation of an active low pass filter. If you intend to use this particular circuit in a product, variation in frequency response between individual products will most probably lead to unacceptable field reliability.


There are many other examples of “design” tools that can be used as “analysis” tools. In fact, any design tool that provides knowledge on potential product failure modes, and the prevention thereof, can be used as valuable reliability engineering tool. Other examples include electronic component derating analysis, tolerance analysis, signal integrity analysis, electromagnetic compatibility analysis, thermal analysis, finite element analysis, vibration and shock analysis, load-strength analysis and fatigue analysis.

2 Failure analysis

Failure analysis, performed with the objective of understanding how the product or system will react to potential failure modes, is extremely useful to influence a design. Typical analyses include reliability block diagram analysis, design (and process) FMEA (Failure Mode and Effects Analysis) and FTA (Fault Tree Analysis).

FMEA can be described as a bottom-up analysis where potential failure modes of a product or system are identified, and the effects of these failure modes on a higher level are determined. For each potential failure mode, the probability of occurrence and the ability to detect it are also determined. FTA uses top-down logic to determine what failures (and in what combinations) can cause an undesirable event to occur. Both are well-known and very old reliability analysis tools. FMEA, for example, is described in US DoD standards dating from 1949.

FMEA is one of the most powerful reliability tools available, provided that it is used properly. It is therefore important to briefly highlight a major difference between a Design FMEA and a Logistics FMEA. Many engineers know that FMEA forms part of Logistic Support Analysis (LSA). Typically, in performing a LSA, the product or system Bill of Materials is used to develop a hardware breakdown structure, which forms the basis for listing failure modes. These failure modes are then used to identify logistic support in terms of spare parts, special test equipment and tools, maintenance personnel and documentation. The focus is on how to support the product or system when a failure has occurred. The focus of a design FMEA, on the other hand, is on how to prevent failure from occurring in the first place! It is much more than simply adding the word “failure” to a hardware item, and requires substantial technical input from design engineers. Many companies perform only logistics FMEA, and fail to reap the benefits of this powerful reliability analysis tool during development.

One of the fundamental weaknesses of FMEA results from asking the question “How can this item possibly fail?” Since this is a negative question, it may be difficult to identify all potential failure modes. A design engineer, in particular, may be reluctant to contribute to this process, since nobody is keen to publish a list of design weaknesses! An interesting approach to this problem is to change it into the positive question of “How can I change this design to cause a failure to happen?” In practice, this will immediately help to identify more failure modes, since every design engineer knows exactly how to change a configuration or a part or a parameter into a failure. This approach is known as Anticipatory Failure Determination®, and is an application of TRIZ (or Theory of the Solution of Inventive Problems) on FMEA [1].

Finally, it should be noted that reliability prediction (using the cancelled Mil-Hdbk-217) is not considered a useful reliability engineering analysis tool. This, and other similar reliability prediction methods which attempt to quantify reliability during development, are based on fundamentally flawed assumptions (e.g. Arrehenius equation). They have therefore limited (if any) ability to prevent failures from occurring in the field [2].

[The third and final part of this series will discuss “Test” as verification method in more detail with special reference to HALT and HASS – Editor].

Invitation to SEMAT - The Software Engineering Method and Theory Initiative

By Ivar Jacobson, Bertrand Meyer, Richard Soley

You may have heard that the three of us have been quietly planning a "revolution". The goal is to re-found software engineering as a rigorous discipline. We recognize that the natural tendency in our field is to perturb systems minimally into approximate correctness, but this path cannot be sustained any longer if we are to support the computing industry and help it meet the demands of society. We need to restart on a solid basis, taking advantage of all that has been learned in software engineering theory and practice over the past five decades.

Drawing from the author’s many years of hands-on experience in the field, the book presents the foundation processes and analytical practices for identifying, analyzing, measuring, and managing risk in traditional systems, systems-of-systems, and enterprise systems. After an introduction to engineering risk management, the book covers the fundamental axioms and properties of probability as well as key aspects of decision analysis, such as preference theory and risk/utility functions. It concludes with a series of essays on major analytical topics, including how to identify, write, and represent risks; prioritize risks in terms of their potential impacts on a systems project; and monitor progress when mitigating a risk’s potential adverse effects. The author also examines technical performance measures and how they can combine into an index to track an engineering system’s overall performance risk. In addition, he discusses risk management in the context of engineering complex, large-scale enterprise systems.

MV-22, F-35B: Systems Engineering Fail!

There's a new DARPA solicitation out that every MV-22 and JSF advocate must read.

Here's the first paragraph:

“DARPA is soliciting innovative research proposals in the area of Thermal Management Systems (TMS) for aircraft landing decks. The deployment of the MV-22 Osprey has resulted in ship flight deck buckling that has been attributed to the excessive heat impact from engine exhaust plumes. Navy studies have indicated that repeated deck buckling will likely cause deck failure before planned ship life. With the upcoming deployment of the F-35B Short Take Off and Vertical Landing (STOVL) Joint Strike Fighter (JSF), it is anticipated that the engine exhaust plumes may have a more severe thermo-mechanical impact on the non-skid surface and flight deck structure of ships. Currently, there are no available strategies to mitigate deck buckling and thermal-mechanical deck failure other than heavy structural modifications. The goal of this effort is to exploit thermal management technologies that incorporate a thermally and functionally stable non-skid surface which meets Navy requirements for application, safety, and performance. Eligible technologies should consist of an integrated Thermal Management System (TMS) that mitigates the thermo-mechanical structural impact of the F-35B engine exhaust plumes. It is anticipated that the integrated TMS will be implemented on Navy Landing Helicopter Dock (LHD) 1 and Landing Helicopter Assault (LHA) 6 Class amphibious assault ships.”

Call for Papers: ACM Transactions on Autonomous and Adaptive Systems Special Issue on:
Pervasive Adaptation: Visions & Challenges

Pervasive Adaptation is concerned with models, tools, and technologies to be used in pervasive information and communication systems that are capable of autonomously adapting to highly dynamic contexts. The successful development of future pervasive systems will increasingly require handling complex interactions between intelligent objects, computers, sensors and actuators, and intelligent objects of any kind. The real challenge is to make such interactions fruitful, purposeful, and secure, despite the constantly changing characteristics of the environment (whether social, physical, or technical) in which such systems will operate, in the absence of any centralized control, and possibly even in the absence of a complete understanding of the structure and micro-level functioning of these systems. Clearly, the only way to approach this is to make systems able to adapt themselves (at the level of individual components or at the collective level) over situations and time, taking into account the overall emergent behavior of the system, and possibly offensively exploit the context dynamics to improve and evolve.

This special issues welcomes submissions on any topic related to pervasive adaptation. Survey/tutorial papers focusing on a specific topic of pervasive adaptation and aimed at framing the key concepts, challenges, and related work on that topic, are particularly welcome. Technical papers describing some original technical contribution are equally welcomed, provided they contain enough introductory/survey material to make the paper of general interest behind its specific technical contribution.

Human Factors in Requirements Engineering: - A Survey of Human Sciences Literature Relevant To the Improvement of Dependable Systems Development Processes

Authors: Stephan Viller, John Bowers, Tom Rodden

Abstract:
Requirements engineering (RE) is an inherently social process, involving the contribution of individuals working in an organizational context. Further, failures in the RE process will potentially lead to systematic failures in the products that are produced as a result. Consequently, the RE process for dependable systems development should itself be considered as a dependable process, and therefore subject to greater scrutiny for vulnerabilities to error. Research on human error has typically focused on the work of individual actors from a cognitive perspective. This paper presents a survey which broadens the view on what contributes to human error by also examining work from the social and organizational literature. This review was conducted to inform efforts to improve the systems development process for dependable systems, and in particular their requirements engineering process.

Managing Legal Texts in Requirements Engineering

Authors: Paul N. Otto, Annie I. Antón

Abstract:
Laws and regulations are playing an increasingly important role in requirements engineering and systems development. Monitoring systems for requirements and policy compliance has been recognized in the requirements engineering community as a key area for research. Similarly, legal compliance is critical in systems development, especially given that non-compliance can result in both financial and criminal penalties. Working with legal texts can be very challenging, however, because they contain numerous ambiguities, cross-references, domain-specific definitions, and acronyms, and are frequently amended via new statutes, regulations, and case law. Requirements engineers and compliance auditors must be able to identify relevant legal texts, extract requirements and other key concepts, and monitor compliance. This chapter surveys research efforts over the past 50 years in handling legal texts for systems development. This survey can aid requirements engineers and auditors to better specify, test, and monitor systems for compliance.

Change Impact Analysis for SysML Requirements Models based on Semantics of Trace Relations

Authors: ten Hove, D.; Göknil, A.; Kurtev, I.; van den Berg, K.G.; de Goede, K.
Editors Oldevik, J.; Olsen, G. K.; Neple, T.; Kolovos, D.

Summary:
Change impact analysis is one of the applications of requirements traceability in software engineering community. In this paper, we focus on requirements and requirements relations from traceability perspective. We provide formal definitions of the requirements relations in SysML for change impact analysis. Our approach aims at keeping the model synchronized with what stakeholders want to be modeled, and possibly implemented as well, which we called as the domain. The differences between the domain and model are defined as external inconsistencies. The inconsistencies are propagated for the whole model by using the formalization of relations, and mapped to proposed model changes. We provide tool support which is a plug-in of the commercial visual software modeler BluePrint.

The Systems Engineering Delusion

“…The need for complex interaction between different specialists is not a new economic phenomenon, and in engineering it does indeed require project managers and technical directors who can take a multi-disciplinary overview. This, however, is quite distinct from the Systems Engineering ethos, which attempts to legitimise the creation of a separate discipline which specialises in the top-down analysis of engineering projects in terms of requirements, capabilities and stakeholders, abstracted from concrete engineering issues.”

Standards and Guides

ISO/IEC/IEEE 12207 and 15288: The Entry-Level Standards for Process Definition - Part 1

James W. Moore

In 2008, the 12207 standard for software life cycle processes and the 15288 standard for system life cycle processes were revised in an effort that finally harmonized system and software processes as well as bringing the respective IEEE and ISO/IEC standards into complete agreement. Some users mistakenly believe that these standards are targeted only to large organizations able to make a substantial investment in a complete suite of software and systems processes. However, these standards are also the best entry point for beginning users who desire guidance on as few as a single process. This three-part article will explain how entry-level users can apply the two standards.
