This paper presents an economic production quantity (EPQ) model with a periodic order quantity (POQ) policy, product reliability and periodic demand. The machine reliability has decreased over time; therefore, the rates of perfect and defective products reduce and increase over time, respectively. A fixed percentage of these products are reworked while the rest is wasted. Some equipment in thei...
The control of a stochastic manufacturing system that executes capital asset repairs and remanufacturing in an integrated system is examined. The remanufacturing resources respond to planned returns of worn-out equipments at the end of their expected life and unplanned returns triggered by major equipment failures. Remanufacturing operations for planned demand can be executed at different rates...
هدف مطالعه کنونی تعیین هنجارهای حاکم بر ترجمه ی آهنگهای کارتونها میباشد . به این منظور 30 آهنگ انگلیسی کارتونها و دوبله ی فارسی آنها انتخاب و بررسی شدند. ابتدا بر اساس مدل,low (2013) ترجمه آهنگها به سه دسته تقسیم شدند: 1) .song replacement (3 ,song adaptation (2 ,song translation سپس استراتژیهایی که مترجمین در جهت غلبه بر محدودیتهای ترجمه آهنگها به کار برده بودند بر اساس مدل ,low (2013) تعیین ش...
Novel replacement policies that are hybrids of inspection maintenance and block replacement are developed for an n component series system in which the component parts used at successive replacements arise from a heterogeneous population. The heterogeneous nature of components implies a mixed distribution for time to failure. In these circumstances, a hybrid policy comprising two phases, and ea...
Prefetching is an inbuilt feature of file system and storage caches. The cache replacement policy plays a key role in the performance of prefetching techniques, since a miss occurs if a prefetch block is evicted before the arrival of the on-demand user request for the block. Prefetch blocks display spatial locality, but existing cache replacement policies are designed for blocks that display te...
In This Paper, we focus on estimating the expected total cost and expected cost rate for age replacement under warranty policy. We describe how to use design of Accelerated life testing (ALT) plans by assuming constant stress and life times are independently distributed as Exponentiated Pareto Distribution (EP) for predicting the cost of age replacement under warranty policy. This problem is st...
The probabilistic escape LIFO (peLIFO) policy was proposed as a member of the pseudo-LIFO family of replacement policies [1]. This is a deterministic replacement policy that computes certain probabilities to reach a deterministic eviction decision in last-level caches. This brief note includes a few additional experimental results involving the peLIFO policy, a discussion on the impact of L2 ca...
The Mach external pager interface allows applications to supply their own routines for moving pages to and from second-level store. Mach doesn’t allow applications to choose their own page replacement policy, however. Some applications have access patterns that may make least recently used page replacement inappropriate. In this paper, we describe an extension to the external pager interface th...
We define what is a replacement policy for a system that fails randomly in time and its main characteristics. There are several parameters that drive the structure of the optimal policy. We provide a detailed discussion of the time horizon, objective functions, and failure time distributions as part of any replacement policy.

The aim of this paper is to analyze the macroeconomic effects of parametric reforms. An adjusted Auerbach-Kotlikoff model is used to study the effects of decreasing replacement and contribution rates of the pension system. The first part concentrates on the macroeconomic effect of reforms. Our results indicate that reducing the replacement and contribution rates increase the capital stock and d...
