Traditional methods model the billion-dollar airline crew scheduling problem as deterministic and do not explicitly include information on potential disruptions. Unfortunately, the effort used to optimize crew schedules and reduce crew costs is often wasted as flight schedules are often disrupted. Consequently, airlines spend a great deal of time and money optimizing crew schedules in the plann...

The term resilience describes the ability to survive and quickly recover from extreme unexpected disruptions. A high energy system is of utmost importance modern societies that are highly dependent on continued access services. This review covers terminology assessment a broad landscape threats mapped with proposed framework. more detailed discussion two specific given: weather, which cause for...

Disruptions in end-to-end path connectivity, which last longer than one retransmission timeout, cause suboptimal TCP performance. The reason for this performance degradation is that TCP interprets segment loss induced by long connectivity disruptions as a sign of congestion, resulting in repeated retransmission timer backoffs. This, in turn, leads to a delayed detection of the re-establishment ...

Recent events have highlighted the need for planners to consider the risk of disruptions when designing supply chain networks. Supply chain disruptions have a number of causes and may take a number of forms. Once a disruption occurs, there is very little recourse regarding supply chain infrastructure because these strategic decisions cannot be changed quickly. Therefore, it is critical to accou...

Due to the global expansion of Company A's supply chain network, it is becoming more vulnerable to many disruptions. These disruptions often incur additional costs; and require time to respond to and recover from these disruptions. The base paper supply chain was identified as the most vulnerable area of the Company A Jurong and South & Southeast Asia Cluster supply chain; and a multi-stage sup...

In most real production environment, schedules are usually inevitable with the presence of a variety of unexpected disruptions. Thus it is necessary to develop predictive/reactive schedules which can absorb disruptions while maintaining high shop performance. In this paper, a robust predictive/reactive scheduling method is developed for solving job shop scheduling in dynamic environment. It con...

The Great East Japan Earthquake that occurred on March 11, 2011 caused disruptions to transportation network such as roads and railways. In general, transportation network disruptions make distribution of relief goods difficult and are considered to have negative impact on the economy of the stricken region owing to a decrease in transportation accessibility. Focusing on Iwate Prefecture, which...
