The facility allocation of the supply chain is critical since it directly influences cost efficiency, customer service, responsiveness, risk reduction, network optimization, and overall competitiveness. When enterprises deploy their facilities wisely, they may achieve operational excellence, exceed expectations, obtain a competitive advantage in today's volatile business climate. Due to this re...

The ever-growing volume and value of data has raised increasing pressure for long-term data protection in storage systems. Moreover, the redundancy in data further aggravates such pressure in these systems. It has become a serious problem to protect data while eliminating data redundancy, saving storage space and network bandwidth as well. Data deduplication techniques greatly optimize storage ...

In a remote backup system, transaction processing takes place at the primary and the log records generated at the primary are propagated to the remote backup which uses them to reconstruct a recent state of the database at the primary. In the event of a primary failure, the backup system takes over transaction processing without causing users to observe a breach in service. Existing remote back...

In MPLS networks, failure resilience of a Label Switched Path (LSP) is essential in guaranteeing the QoS of the path. This can be achieved by allocating backup LSPs through which packets can be routed in case of primary LSP failiures. bandwidth efficiency and expeditious path restoration are two desirable features for the design of backup LSPs. This paper tackles the bandwidth efficiency with a...

We consider a network of computers consisting of file servers and a Database Management System (DBMS) where a linkage is maintained, with referential integrity, between data in the DBMS and files in the file servers which are external to the DBMS. We present algorithms for performing backup and recovery of the DBMS data in a coordinated fashion with the files on the file servers. When a file is...

One of the most fundamental elements of any disaster recovery plan is data backup and recovery. If an IT staff lacks the ability to recover lost data following an incident or disaster, redundant hardware or hot sites are of only limited value. Relatively few years ago, planning a backup strategy was reasonably straightforward for the small-office-home-office (SOHO) and small-tomedium-sized-busi...

RaySearch RayStation Fallback (FB) planning module can generate an equivalent backup radiotherapy treatment plan facilitating treatment on other linear accelerators. FB plans were generated from the RayStation FB module by simulating the original plan target and organ at risk (OAR) dose distribution and delivered in various backup linear accelerators. In this study, helical tomotherapy (HT) bac...
