This research investigates the impact of electronic replenishment strategy on the operational activities and performance of a two-stage make-to-order supply chain. We develop simulation-based rolling schedule procedures that link the replenishment processes of the channel members and apply them in an experimental analysis to study manual, semi-automated, and fully automated e-replenishment stra...

Forested wetlands with high water tables are sensitive to disruption from harvesting yet support commercially desired tree species like northern white-cedar. Winter harvest was conducted in Maine, USA, compare operational costs and productivity of cut-to-length cedar (fragile soil) non-cedar stands (mixedwood, sturdy soil), evaluate uncertainties influential factors, forecast time for post-harv...

on nonclinical operations and did not seek the active involvement of physicians. Yet clinical care accounts for a significant portion of operational expenditures at most hospitals. Without significant changes to how clinical care is delivered, hospitals will not be able to achieve the 5to 10-percent reduction in operational costs that most experts believe is needed to cope with today’s economic...

do not always match with others and whose individual information systems often differ. This inherent complexity can create a degree of fragmentation, causing lowered service levels and increased operational costs. In addition to the operational challenge, further pressure on IT systems development and maintenance is caused by legislation on security and customs, and ongoing change in customer r...

Cloud computing is becoming a popular way of supplying and using computing resources. A cloud-computing data center is equipped with a large number of physical resources and must manage an even larger number of virtual machines (VMs). The center’s VM placement strategy affects the utilization of physical resources, and consequently, it influences operational costs. Our goal is to develop a mult...

A two component system can be fully operational, in two states of intermediate degradation, or fail. Each component is protected by a defender which maximizes its reliability weighted against the defense costs, and attacked by an attacker which maximizes its unreliability weighted against the attack costs. The system reduces to the series system when the values of the two intermediate states eq...

This paper reports on the application of the operational complexity index [Frizelle, G., Woodcock, E., 1995. Measuring complexity as an aid to developing operational complexity. International Journal of Operations and Production Management 15(5), 26–39]. The aim is to address what is the relationship between costs and the complexity index. The investigation carried out measurements on two types...

freight service is reinvested in passenger service improvements. The freight carrier, in shifting goods from trucks to rail, can potentially benefit from (a) more reliable travel times for goods, particularly during periods of nonrecurrent congestion, (b) cheaper transport costs, and (c) fewer truck accidents. Society may benefit from reduced truck traffic through reductions in (a) harmful gree...
