Packet Radio Networks (PRNETs), which are also called ad-hoc networks, have the capability of fast (and ad-hoc) deployment and set-up, and therefore potentially have several useful civilian and military applications. Building low-energy PRNETs is an important design goal, because the communication devices are typically powered by batteries, and therefore are useless when the batteries are deple...

For a large multi-hop wireless network, nodes are preferable to make distributed and localized link-scheduling decisions with only interactions among a small number of neighbors. However, for a slowly decaying channel and densely populated interferers, a small size neighborhood often results in nontrivial link outages and is thus insufficient for making optimal scheduling decisions. A question ...

tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

Millimeter-wave (mmWave) communication is a promising technology to cope with the expected exponential increase in data traffic in 5G networks. mmWave networks typically require a very dense deployment of mmWave base stations (mmBS). To reduce cost and increase flexibility, wireless backhauling is needed to connect the mmBSs. The characteristics of mmWave communication, and specifically its hig...

In a large multi-hop wireless network, nodes are preferable to make distributed link-scheduling decisions with information exchange only among a small number of neighbors. However, for a slowly-decaying channel and densely-populated interfering nodes, a small size neighborhood often results in nontrivial link outages and is thus insufficient for making optimal scheduling decisions. A question a...

Abstract In this paper, we consider a combination of the joint replenishment problem (JRP) and single-machine scheduling with release dates. There is single machine one or more item types. Each job has date, positive processing time, it requires subset items. A can be started at time t only if all required types were replenished between date point . The ordering for distinct jobs combined. obje...

Nowadays, nurses scheduling is one of the most important challenges with which health care centers are encountered. The significance of nurses’ work quality has led researchers to be concerned about scheduling problems, which have an impact on nurses’ performance. Observing the interests of hospital and patients, providing their satisfaction, and meeting their needs are among the main objective...
