      <title>OPTIMUM CONFIGURATIONS OF AN N-SECTION SYSTEM</title>
      <link>https://trid.trb.org/View/179777</link>
      <description><![CDATA[Reliability optimization methods are used for computer-aided design of power-cable system such as in RTS (Rapid Transit System) on the basis of minimizing inconvenience hours per year (IHY), the users viewpoint, with respect to a set of admissible configurations.]]></description>

      <title>SAFETY EVALUATION OF MASS TRANSIT SYSTEMS BY RELIABILITY ANALYSIS</title>
      <link>https://trid.trb.org/View/25181</link>
      <description><![CDATA[A problem-independent concept for the reliability analysis of complex systems is presented.  A method of system reliability analysis which is based on a selection of generally applicable mathematical models and computer programs for efficient numerical evaluation of the models emerges from this concept, general safety model based on the same reliability analysis techniques and procedures is presented.  A case study shows the application of the safety models and the methods of reliability analysis.]]></description>

      <title>IMPROVED MANAGEMENT APPROACH TO UPGRADE AVIONIC SYSTEM RELIABILITY</title>
      <link>https://trid.trb.org/View/72576</link>
      <description><![CDATA[An improved reliability management-approach for upgrading avionic system reliability is presented.  Management of the program was by no means of an improvement control plan that included continuously updated field performance data, the improvements planned, and projections of the numerical reliability increase with the changes incorporated.  The use of special teams working concurrently to improve design, parts, and manufacturing processes is discussed.  Presented are measured field results that verify the effectiveness of these improvement efforts.]]></description>

      <title>QUEUING MODELS FOR ESTIMATING AIRCRAFT FLEET AVAILABILITY</title>
      <link>https://trid.trb.org/View/73691</link>
      <description><![CDATA[The availability of a small fleet of aircraft in a flying-base, repair-depot combination is modeled and studied.  A deterministic flow model relates parameters of interest and represents the state-of-the art in the planning of such systems.  A cyclic queue model shows the effect of the principal uncertainties in operation and repair and shows the consequent decrease in the availability of aircraft at the flying-base.  Several options such as increasing fleet size, investments in additional repair facilities, or building reliability and maintainability into the individual aircraft during its life-cycle are open for increasing the availability.  A life-cycle cost criterion brings out some of these features.  Numerical results confirm Rose's prediction that there exists a minimal cost combination of end products and repair-depot capability to achieve a prescribed operational availability.]]></description>

      <title>OPTIMAL DECISION RULE FOR REPAIR VS REPLACEMENT</title>
      <link>https://trid.trb.org/View/72136</link>
      <description><![CDATA[This paper presents a policy for either repairing or replacing a system that has failed.  The policy applies to systems whose mean residual life function is decreasing.  An optimal policy is developed that minimizes the cost per unit time for repair and replacement.  Results are shown graphically for a particular distribution of time to failure and are motivated in terms of an automobile replacement problem.]]></description>

      <title>RELIABILITY ENGINEERING AND SAFETY AT SEA</title>
      <link>https://trid.trb.org/View/26809</link>
      <description><![CDATA[This paper surveys the field of reliability as related to marine engineering.  The problems in marine systems are characterized by availability and safety.  However, the two are different aspects of the same problem, and the discipline of reliability engineering provides solution tools for both.  The reliability and availability of the propulsion, navigation and cargo handling are vitally important to the economic operation of ships.  Equally important are safe handling of hazardous cargoes and safe navigation through restricted waters and in areas of high traffic density.  Experience in dealing with marine equipment and systems has shown that the available techniques and methods of reliability engineering should be applied with care in marine engineering.  Special attention should be paid to failure cause, mechanism, and mode.  Some proven methods are discussed.]]></description>

      <title>STATE OF RELIABILITY EFFORT OF THE EUROPEAN RAILWAYS</title>
      <link>https://trid.trb.org/View/24821</link>
      <description><![CDATA[Reliability, in the sense of safety and punctuality, is the principal objective of railway management to keep ahead of competition.  Reliability efforts of European railways and the impact of modern methods for improving reliability are discussed.  Further progress in this field depends on modern information systems and complex data processing.  The proposed European data-processing system and the already installed systems of several European railway authorities are introduced.  In addition to safety, reliable systems were also shown to have the highest economic gain.  Modern computers help to overcome the poor out-of-date information characterized by the high error rate of manual systems.]]></description>
