Efficiency and fairness are two important goals of disaster rescue. However, the existing models usually unilaterally consider the efficiency or fairness of resource allocation. Based on this, a multiobjective emergency resource allocation model that can balance efficiency and fairness is proposed. The object of the proposed model is to minimize the total allocating costs of resources and the total losses caused by insufficient resources. Then the particle swarm optimization is applied to solve the model. Finally, a computational example is conducted based on the emergency relief resource allocation after Ya’an earthquake in China to verify the applicability of the proposed model.

ABSTRACT Abstract 2017-370. As a result of a successful modification to an Oil Spill Response Limited Boeing 727 aircraft (registration G-OSRA) to enable aerial dispersant spraying, a paper has been written, aiming to provide an insight into the introduction of a turbine aircraft dispersant-application platform and the implications of the evolution from turboprop to jet engine aircraft. Furthermore, Oil Spill Response Limited has recently commissioned and introduced a second aircraft of the same modification specification (registration G-OSRB). As a response technique, dispersant application can have a significant impact on tackling large quantities of oil at sea; however, much of its effectiveness relies on targeting the oil during the window of opportunity in which dispersant will work successfully, in the early stages of the weathering processes. Time is, therefore, a critical factor and it is this key aspect, as well as others explored in detail throughout the paper, that led to the development of a pioneering system, specifically designed to respond to oil spills, that will undoubtedly prove to have a positive impact in terms of response times to incident sites. The paper also presents the reasons supporting the choice of a Boeing 727-2S2F (RE) aircraft as the chosen platform for dispersant spraying operations, such as the power to weight ratio, cargo capacity, and rearward mounted engine positions, to name but a few. It is also important to analyse the benefits of the Boeing 727-2S2F (RE) and the dispersant spraying system it contains during the different stages of the incident life cycle, be it during the preparation phase or the response phase. In the preparation phase, one of the advantages to highlight is the resilience of having two aircraft operated under a back to back schedule of maintenance as envisioned by a maintenance program specially designed to ensure continuous operational availability. During the response phase, aircraft such as G-OSRA and G-OSRB benefit from reduced transit times to incident sites due to the higher speed through the air that is possible with jet aircraft. Also, the paper also compares some key performance indicators such as range and speed between the turboprop aircraft of choice, Hercules L-382 and the Boeing 727-2S2F (RE).

Oil spills can be difficult to manage, with reporting frequently delayed. Too often, by the time responders arrive at the scene, the slick has moved, dissolved, dispersed or sunk. This Oil Spill Monitoring Handbook provides practical advice on what information is likely required following the accidental release of oil or other petroleum-based products into the marine environment. The book focuses on response phase monitoring for maritime spills, otherwise known as Type I or operational monitoring. Response phase monitoring tries to address the questions – what? where? when? how? how much? – that assist responders to find, track, predict and clean up spills, and to assess their efforts. Oil spills often occur in remote, sensitive and logistically difficult locations, often in adverse weather, and the oil can change character and location over time. An effective response requires robust information provided by monitoring, observation, sampling and science. The Oil Spill Monitoring Handbook completely updates the Australian Maritime Safety Authority’s 2003 edition of the same name, taking into account the latest scientific advances in physical, chemical and biological monitoring, many of which have evolved as a consequence of major oil spill disasters in the last decade. It includes sections on the chemical properties of oil, the toxicological impacts of oil exposure, and the impacts of oil exposure on different marine habitats with relevance to Australia and elsewhere. An overview is provided on how monitoring integrates with the oil spill response process, the response organisation, the use of decision-support tools such as net environmental benefit analysis, and some of the most commonly used response technologies. Throughout the text, examples are given of lessons learned from previous oil spill incidents and responses, both local and international. General guidance of spill monitoring approaches and technologies is augmented with in-depth discussion on both response phase and post-response phase monitoring design and delivery. Finally, a set of appendices delivers detailed standard operating procedures for practical observation, sample and data collection. The Oil Spill Monitoring Handbook is essential reading for scientists within the oil industry and environmental and government agencies; individuals with responder roles in industry and government; environmental and ecological monitoring agencies and consultants; and members of the maritime sector in Australia and abroad, including officers in ports, shipping and terminals.

ABSTRACT When a marine oil spill occurs there are critical challenges that fall into four categories—the Four Cs—that face the Responsible Party (RP): the Casualty, the Community, the Corporation, and the Cleanup. In the case of a company that has a corporate response team, it will be charged with the management of all four categories. In Canada, the detailed management of the Cleanup can be delegated to the Certified Response Organization (RO). However, a reporting relationship from the RO to the RP response management team must be established, both to ensure they keep each other informed and to avoid duplication or conflict in cleanup activities. Since the Cleanup is primarily a responsibility of the RP Operations Section, the reporting chain during the Initial Response Phase and Tactical Phase should be from the RO Spill Response Manager to the RP Operations Manager. Once the Cleanup is the only ongoing challenge, the RP team may be disbanded and only re-assembled for progress assessments of the RO work. During this Strategic Phase of the response, the RO Spill Response Manager will report directly to the RP On-Scene Commander or delegate.
