Usually the warranty data response used to make predictions of future failures is the number of weeks (or another unit of real time) in service. Use-rate information usually is not available (automobile warranty data are an exception, where both weeks in service and number of miles driven are available for units returned for warranty repair). With new technology, however, sensors and smart chip...

The reliability and resource management of products for warranty is important. Furthermore, the number failures aproduct over time use level expenditure can assume different distributions. Approaches with parametric modelsbring good results when there a normal distribution, application Deep Learning (DL) very promising. Weshow new methodology DL models transfer learning to bivariate forecasts r...

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 document presents the results obtained by TREND partners working on core, metro networks, data centers and cloud. More efficient network and data centers design and architectures are proposed. Energy-efficient network operation using load proportionality are presented and more efficient network design are proposed Keyword list: Core networks, OFDM transmission format, network architecture, ...

abstract background: the pressure of consumption spots in eater supply systems is one of the most important hydraulic parameters can be used in optimized management of water distribution networks. since the pressure has some different effects on various parameters of the network management including its hydraulic functions, reliability, stability and leakage, its control is of great importance ...

This paper analyses life cycle cost for equipment protected by both base and extended warranty policies from a consumer’s perspective. We assume that the equipment have two types of failures: minor and catastrophic. A minor failure can be corrected by a minimal repair whereas a catastrophic failure can only be removed by a replacement. The equipment is assumed to be maintained at no charge to t...

Most of the brand new items are released on the market with a certain type of warranty. A xed length warranty period is assumed in this paper. A maintenance policy which consists of minimal repair and preventive maintenance is analyzed for the case of known and unknown failure parameters of the item's lifetime distribution. For the second case, two types of Bayesian policies are considered. An ...
