This paper addresses the essential elements and strategies that should be in place for large-scale evacuations under emergency situations, particularly in densely used networks such as in Toronto, Ottawa, Vancouver and Montreal to name a few. Some questions that possess some indispensable information to achieve that goal are proposed. A novel framework that addresses these questions is proposed...

Crises and natural disasters are always existed in human history, and continue to exist in the future; therefore, people are always affected by these natural disasters. Hence, evacuation planning after natural disasters (e.g., earthquakes, floods, tsunamis, fire, storms, warfare and nuclear explosions) is vital. Given that natural disasters cause irreparable financial loss and the loss of life ...

Stations are the main components of the subway systems. Despite the progress in the construction and maintenance, stations have always been exposed to the natural and man-made disasters. In such incidents, the station’s evacuation capability has a direct relation with a passenger's life. Various factors affect the station's evacuation capability. Investigation of these factors and evaluation of...

Evacuation route planning identifies paths in a given transportation network to minimize the time needed to move vulnerable populations to safe destinations. Evacuation route planning is critical for numerous important applications like disaster emergency management and homeland defense preparation. It is computationally challenging because the number of evacuees often far exceeds the capacity,...

In December 2004, the Sumatra-Andaman earthquake occurred. It triggered tsunamis, and tragedy fell upon many people. Not only earthquakes but also diverse disasters occurred and caused serious damages in many countries. Therefore it is very important to establish crisis management systems against large-scale disasters such as big earthquakes, conflagrations and tsunamis to secure evacuation pat...

INTRODUCTION The evacuation of a health care facility is a complex undertaking, especially if done in an immediate fashion, ie, within minutes. Patient factors, such as continuous medical care needs, mobility, and comprehension, will affect the efficiency of the evacuation and translate into evacuation resource needs. Prior evacuation resource estimates are 30 years old. METHODS Utilizing a c...

In this study we present a general matheuristic that decomposes the problem being solved in a master and a subproblem. In contrast with the column generation technique, the proposed approach does not rely on the explicit pricing of new columns but instead exploits features of the incumbent solution to generate one or more columns in the master problem. We apply this approach to large scale evac...
