| 1. | A planned replacement policy for a system with limited repairable spares
有限可修备件条件下系统计划更换策略 |
| 2. | The proxy system has good scalability . secondly , design and realize a segment - based caching replacement policy
2 、设计并实现了一个基于节目分段缓存的缓存接纳控制和缓存替换策略。 |
| 3. | In the next section of this paper we describe a non - generational ga for multiobjective optimization problems ( mop ) . in it the replacement policy is such that an offspring replaces the worst one in the current population only if it is better then it
在将错位交叉算子应用于多目标优化问题求解时，本文提出一种基于非群体迭代型的小生境多目标优化遗传算法，即算法迭代过程中不是更换种群全部或大部分个体，而是每次更新群体中最差的个体。 |
| 4. | When managing files , srms allocate space for files , invoke file transfer services to move files into the space , pin files for a certain lifetime , release files upon the client s request , and use file replacement policies to optimize the use of the shared space
在管理文件时， srm会为文件分配空间，调用文件传输服务将文件移动到这些空间中，为这些文件提供一定的生命周期，在客户机请求完成之后释放这些文件，并使用文件替换策略来优化对于共享空间的使用。 |
| 5. | 2 . according to the research on proxy cache replacement policies , it is discussed that replacement algorithms based on cost / value model are preferable . however , the model requires to be modified and simplified to easily calculate , to reflect web access characteristics and to reduce access latency
2 、通过对代理缓存的替换策略的研究，论述了基于成本价值模型的替换算法是较优的，但必须修正和简化其模型，使计算相对简单，又能体现web的访问特性，减少延迟。 |
| 6. | Now it has become an international main research area in which the studies on consistency policies and replacement policies always are the two directions of research , while the front of research on proxy caching techniques is how to better incorporate these two policies which results in a desirable performance of a proxy caching system
其中，一致性策略和替换策略的研究一直是提高代理缓存系统性能的两个研究方向，而如何将一致性策略和替换策略有机地结合起来，以便有效地提高代理缓存系统的性能是代理缓存技术的研究前沿。 |
| 7. | 4 . a new algorithm called acr ( adaptive consistency and replacement algorithm ) is proposed , designed and implemented . it incorporates cache consistency policy with cache replacement policy in which the cache consistency policy is adaptive ttl mechanism , while the cache replacement policy is based on a cost / value model
广西大学硕士论文基于internet的代理缓存技术研究摘要4 、提出、设计和实现了自适应一致性一替换算法（即acr算法人该算法包括一致性策略和替换策略两部分，一致性策略采用自适应ttl机制，替换策略是基于成本价值模型的算法。 |
