A predictive-maintenance structure for a gradually deteriorating single-unit system (continuous time/continuous state) is presented in this paper. The proposed decision model enables optimal inspection and replacement decision in order to balance the cost engaged by failure and unavailability on an infinite horizon. Two maintenance decision variables are considered: the preventive replacement t...

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...

AbstractDynamic data distribution is used to enhance data locality and algorithm performance with reducing inter-processor communication in data parallel programs on distributed memory multi-computers. Since the exchange of data is performed at run-time, there is a performance tradeoff between the efficiency of the new data decomposition for a subsequent phase of an algorithm and the cost of ex...

Previous cache studies are becoming rather outdated, since they deal with older benchmarks (such as those in SPEC92) and smaller cache conngurations than are now feasible. We remedy this situation by performing a battery of cache tests on several interesting programs in the SPEC95 suite. The applications of chief interest to us are those that are represent current trends in computing, such as i...

We prove theorems that show that if we can reorder a program's memory reference stream such that the reordered memory reference stream satis es a disjointness property, then the transformed program corresponding to the reordered stream is guaranteed to have fewer misses for any cache with arbitrary size or organization so long as the cache uses the LRU replacement policy. We can apply these res...

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...
