Systems that are more dependable and less expensive to maintain may be more expensive to purchase. If ordinary customers cannot calculate the costs of downtime, such systems may not succeed because it will be difficult to justify a higher price. Hence, we propose an easy-tocalculate estimate of downtime. As one reviewer commented, the cost estimate we propose ‘‘is simply a symbolic translation ...

For an electronic business (e-business), customer satisfaction can be the difference between long-term success and short-term failure. Customer satisfaction is highly impacted by Web server availability, as customers expect a Web site to be available twenty-four hours a day and seven days a week. Unfortunately, unscheduled Web server downtime is often beyond the control of the organization. Wha...

Software upgrades are one of the leading causes of downtime in IT infrastructures. Long running datamigration processes require intensive up-front preparation, extended maintenance windows and close monitoring, and they impose a significant burden on the system administrators. Even worse, major upgrades sometimes fail due to complex, hidden dependencies within the system, causing unplanned down...

In the field of fault tolerance estimation, increasing attention in electrical motors is detection and diagnosis. The tasks performed by these machines are progressively complex enhancements likewise looked for It has now turned out to be essential diagnose faults at their very inception; as unscheduled machine downtime can upset deadlines cause heavy financial burden. this paper, diagnosis spe...

It was reported in the literature that the coefficients of variation of uptime and downtime of manufacturing equipment are often less than 1. This technical paper is intended to provide an analytical explanation of this phenomenon. Specifically, it shows that the distributions of uptime and downtime have the coefficients of variation less than 1 if the breakdown and repair rates are increasing ...

Nowadays, by successful application of on time production concept in other concepts like production management and storage, the need to complete the processing of jobs in their delivery time is considered a key issue in industrial environments. Unrelated parallel machines scheduling is a general mood of classic problems of parallel machines. In some of the applications of unrelated parallel mac...

The evolution in precision manufacturing has resulted in the requirement to produce and maintain more accurate machine tools. This new requirement coupled with desire to reduce machine tool downtime places emphasis on the calibration procedure during which the machine’s capabilities are assessed. Machine tool downtime is significant for manufacturers because the machine will be unavailable for ...

IT Infrastructure Management and server downtime have been an area of exploration by researchers and industry experts, for over a decade. Despite the research on web server downtime, system failure and fault prediction, etc., there is a void in the field of IT Infrastructure Downtime Management. Downtime in an IT Infrastructure can cause enormous financial, reputational and relationship losses ...

(ABSTRACT) High availability is a critical feature of data centers, cloud, and cluster computing environments. Replication is a classical approach to increase service availability by providing redundancy. However , traditional replication methods are increasingly unattractive for deployment due to several limitations such as application-level non-transparency, non-isolation of applications (cau...
