可修排队系统中可靠性指标的分解

本文提出了一种分析可修排队系统的新信息处理－分解法，应用该方法我们重新讨论了服务器可修的Ｍ／Ｇ／１排队系统，获得服务器在时刻ｔ失效的概率和在（０，ｔ］中失效的平均次数这两个主要可靠性指标的分解结果，而且进一步分析了服务器可修的ＧＩ／Ｇ１排队系统。值得注意的是本文提出的解解法新颖、简洁。     

Subtle gate oxide defect elimination to improve the reliability of a 32M-bit SRAM product

Tiny defects may escape from in-line defect scan and pass WAT (Wafer Acceptance Test), CP (Chip Probing), FT (Final Test) and SLT (System Level Test). Chips with such kind of defects will cause reliability problem and impact revenue significantly. It is important to catch the defects and derive the prevention strategy earlier in the technology development stage. In this paper, we investigate an SRAM with tiny defects which passed in-line defect scan, WAT, CP and FT but failed in HTOL (High Temperature Operation Life) test, one of the product reliability qualification items. FA (Failure Analysis) reveals gate oxide missing defect is the root cause. The goal is to pass reliability qualification and release product into production on schedule. The failure mechanism, optimization of gate oxide process, enhancement of defect scan and testing methodology will be introduced. Experiment results show very good HTOL performance by the combination of process and testing optimization.

Optimum component switching for systems that operate and idle

Whilst the selection of optimum redundancy designs, in the presence of opposite failure modes, has received much attention in the literature, the associated problem of optimum management of such redundant systems has hitherto been ignored.This note considers the determination of the optimum switching policy for redundancy designs in terms of a cost formulation which weights each of the two failure modes and allows for a cost associated with the repeated switching of components. The integrated design and switching problem is also discussed. By considering all possible three component series — parallel systems, it is demonstrated that the optimum switching policy is critical in the determination of the optimum redundancy design.     

Survivable routing in IP-over-WDM networks: An efficient and scalable local search algorithm

In IP-over-WDM networks, a logical IP network is routed on top of a physical optical fiber network. An important challenge here is to make the routing survivable. We call a routing survivable if the connectivity of the logical network is guaranteed in the case of a failure in the physical network. In this paper we describe FastSurv, a local search algorithm for survivable routing. The algorithm works in an iterative manner: after each iteration it learns more about the structure of the logical graph and in the next iteration it uses this information to improve its solution. The algorithm can take link capacity constraints into account and can be extended to deal with multiple simultaneous link failures and node failures. In a large series of tests we compare FastSurv with current state-of-the-art algorithms for this problem. We show that it can provide better solutions in much shorter time, and that it is more scalable with respect to the number of nodes, both in terms of solution quality and run time.
