reliability design in dynamic programming

Since cost is a major issue in NT design, NTD-RC is applicable for critical applications requiring maximized reliability. This paper formulates a dynamic programming (DP) scheme to help solve NTD-RC. Dynamic programming is both a mathematical optimization method and a computer programming method. This algorithm is based on the studies of the characters of the problem and Misra [IEEE Trans. » Embedded Systems How do we decompose the all-pairs shortest paths problem into sub problems? » About us » C install the links, the NT design problem, called NTD-RC, aims to find an NT that has the maximum reliability with cost within the budget. Log in. Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. An optimal reliability design is one in which all possible means available to a designer have been explored to enhance the reliability of the system with minimum cost under the constraints imposed on the development of a system. 287.9 and the corresponding optimal values are as shown in Table 10. Then the reliability of the function can be given by πr1. How do we use the recursive relation from (2) to compute the optimal solution in a bottom-up fashion? INFORMS promotes best practices and advances in operations research, management science, and analytics to improve operational processes, decision-making, and outcomes through an array of highly-cited publications, conferences, competitions, networking communities, and professional development services.

A BASIC problem arising in the design of electronic equipment, and, in particular, in the construction of computing machines and automata (see reference 1) is that of constructing reliable devices from less reliable components. How do we express the optimal solution of a sub problem in terms of optimal solutions to some sub problems?

A dynamic programming formulation for a k-stage graph problem is obtained by first noticing that every s to t path is the result of a sequence of k-2 decisions. Let c is the maximum allowable cost and ci be the cost of each unit of device i. Redundancy allocation by dynamic programming 5. » C » Privacy policy, STUDENT'S SECTION » News/Updates, ABOUT SECTION But this maximization should be considered along with the cost. And the reliability of the stage I becomes (1 – (1 - ri) ^mi). If r1 = 0.99 and n = 10 that n devices are set in a series, 1 <= i <= 10, then reliability of the whole system πri can be given as: Πri = 0.904. Select the purchase Which is much better than that of the previous case or we can say the reliability is little less than 1 - (1 - ri) ^mi because of less reliability of switching circuits. Here, switching circuit determines which devices in any given group are functioning properly. Environment, energy and natural resources Access supplemental materials and multimedia.

A new dynamic programming method for reliability & redundancy allocation in a parallel-series system Abstract: Reliability & redundancy allocation is one of the most frequently encountered problems in system design. 4. Dynamic Programming is mainly an optimization over plain recursion. : If we imagine that r1 is the reliability of the device. Manufacturing operations Languages: Moreover, Dynamic Programming algorithm solves each sub-problem just once and then saves its answer in a table, thereby avoiding the work of re-computing the answer every time. The reliability of the system can be given as follows: If we increase the number of devices at any stage beyond the certain limit, then also only the cost will increase but the reliability could not increase.
