____________________ WORLD TECHNOLOGIES ____________________ Chapter- 4 Reliability Engineering Reliability Engineering is an engineering field, that deals with the study of reliability: the ability of a system or component to perform its required functions under stated conditions for a specified period of time. It is often reported as a probability. Overview A Reliability Block Diagram Reliability may be defined in several ways: • The idea that something is fit for a purpose with respect to time; • The capacity of a device or system to perform as designed; • The resistance to failure of a device or system; • The ability of a device or system to perform a required function under stated conditions for a specified period of time; • The probability that a functional unit will perform its required function for a specified interval under stated conditions. • The ability of something to fail well (fail without catastrophic consequences) ____________________ WORLD TECHNOLOGIES ____________________ Reliability engineers rely heavily on statistics, probability theory, and reliability theory. Many engineering techniques are used in Reliability Engineering, such as reliability prediction, Weibull analysis, thermal management, reliability testing and accelerated life testing. Because of the large number of reliability techniques, their expense, and the varying degrees of reliability required for different situations, most projects develop a reliability program plan to specify the reliability tasks that will be performed for that specific system. The function of Reliability Engineering is to develop the reliability requirements for the product, establish an adequate reliability program, and perform appropriate analyses and tasks to ensure the product will meet its requirements. These tasks are managed by a reliability engineer, who usually holds an accredited engineering degree and has additional reliability-specific education and training.

1 1 Requirements for Reliability Engineering: Design for Reliability, Reliability Systems Integration, and Reliability-Based System Sustainment If you don’t know where you are going, you might wind up some-where else. Yogi Berra Introduction The objective of this chapter is to define what a Reliability Engineering and analysis program must include in order to achieve design for reliability • reliability systems engineering • reliability-centered system sustainment • The scope of this chapter is to inform the reader of the “what” of a reliability program. The subsequent chapters describe the “how.” Reliability Engineering is the understanding of failure mechanisms. Failure mechanisms form the basis of design analysis, design art, and the bill of materials for a part • part integration into assemblies, assembly integration into subsys-• tems, subsystem integration into systems sustainment of fielded systems • Reliability Engineering is a multidiscipline body of knowledge that enables engineers to characterize the reliability of a part, the maintainability of a part, and the availability of a part. Part reliability determines part maintainability, and the combination of the two determines part availability (see Figure 1.1). Reliability Engineering is applied to mechanical, electrical, electronics, civil, and chemical engineering disciplines. 2 Practical Reliability Engineering Part reliability describes and measures the failure mechanisms acting on the part, the part failure modes caused by the failure mechanisms, the effects of the failure modes on the part, and successive effects of the part failure mode on the higher design hierarchies up to and including the system. Part maintainability describes and measures fault detection of the failure mecha-nisms acting on the part, the isolation of the fault to a part, the mean time to repair the part, and the logistical aspects of part repair.

Chapter Ten Reliability Engineering RATIONAL DESCRIPTIONS OF RELIABILITY IN RECENT years, especially since the advent of space exploration, there has been increased emphasis on what is called Reliability Engineering. When a space capsule is launched, if something goes wrong with the equipment, there is no way to repair it without prohibitive expense. There is great pressure upon the engineer therefore to design space equipment so that it will be more reliable. The pressure for reliability, however, is not confined to engineering for space. Increased emphasis upon automotive safety also causes increased attention to reliable designs. Laws which make the manu-facturer more responsible for accidents caused by his products serve to increase the importance the manufacturer places on reliability in automotive engineering. Unfortunately, at the present time it is not generally recognized that reliability is a property of our state of knowledge about a device or system, and is not a property of the thing itself. It is true that a device does or does not function properly. However, when we inquire whether or not a device is reliable, we are asking for a statement of the knowledge about the device. If historical experience with the device is available, it should be used. But in many cases we do not have historical data to fall back on. Then we must use other information. In any case, a statement about reliability is a statement which concerns itself with our knowledge of the system. The official definition of reliability of the National Aeronautics and Space Administration is: the probability of a device performing adequately for the period of time intended under the operating conditions encountered. Since the word reliability is defined by NASA as a probability, if the results of Chapter One are accepted, reliability is identified with a state of knowledge, not a state of things. 421

To obtain optimal reliability and mutually beneficial results, suppliers and customers in the supply chain should cooperate. The IEEE Reliability Program Standard 1332 (IEEE Standards Project Editors 1998) identifies three reliability objectives between suppliers and customers:- The supplier, working with the customer, should determine and understand the customer's requirements and product needs so that a comprehensive design specification can be generated.
- The supplier should structure and follow a series of engineering activities so that the resulting product satisfies the customer's requirements and product needs with regard to product reliability.
- The supplier should include activities that assure the customer that reliability requirements and product needs have been satisfied.
1.8 Summary
Reliability pertains to the ability of a product to perform without failure and within specified performance limits for a specified time in its life-cycle application conditions. Performance and quality are related to reliability. Performance parameters typically describe the functional capabilities of a product. Quality parameters are commonly used to assess the manufacturing goodness and the ability of a product to work when first received by the customer.Reliability Engineering deals with preventing, assessing, and managing failures. The tools of reliability engineers include statistics, probability theory, and many fields of engineering and the sciences related to the problem domain.Problems

A reliable design takes into consideration all possible ways, such as structural redundancy, derating, safety, environmental factors etc., of improving the reliability within the resources available. Having got the best possible engineering design, we can lose on inherent reliability if we ignore the necessity of stringent quality control during manufacturing. Quality in its simplest interpretation is reliability during manufacture, which ensures that only proper materials, processes and quality control techniques have been used. 15 CONCEPT AND DEFINITION DESIGN AND DEVELOPMENT Birth MANUFACTURE AND I N S T A L L OPERATION AND MAINTENANCE M A I N T A I N A B I L I T Y h H QUALITY t Death R E L I A B I L I T Y ( R e l i a b i l i t y is a B i r t h to D e a t h P r o b l e m ) Fig.1.2 Phases in Equipments Life On the other hand, use reliability gets affected by the conditions of use, maintenance and environment. Like quality, maintainability can also be considered akin to reliability during operation and maintenance phase. Unless proper packaging instructions for storage, shipment and use, operating manuals, maintenance procedures, spare parts, training of maintenance personnel and conditions of environment are prescribed, it would be meaningless to expect a high value of use reliability. Fig.1.3 shows the break up of operational reliability into its various elements.

The benefits of reliable systems are enormous and include a reduction in unexpected failures, lower main-tenance costs, lower life-cycle costs, improved safety, less need for in-process inventory to cover downtime and more consistent quality [1,2]. Prior to World War II, the concept of reliability had been intuitive, subjective, and qualitative. Today, it is a well-recognized discipline with many specialized areas, including that of human reliability, robot reliability, software reliability, and mechanical reliability. The reliability field is generally regarded as having started before World War II, with the development of V1 and V2 rockets in Germany.
