    Multinational operations are carried out to achieve military and diplomatic objectives in various regions. Such operations derive a great deal of benefits from sharing budgets, political legitimacy, sharing each national experience and technological resources, and so forth. However, a coalition, one structure of multinational operations, often involves serious challenges in such areas as command and control, logistic support, communication and language, training, and intelligence and information due to its ad hoc characteristics. This research reviews general problems in a coalition operation, and develops the Coalition Operation Planning Model to assist coalition commanders or staff in producing an efficient operational plan. In this model, goal programming is employed to formulate the coalition problems with multiple objectives. The proposed model is composed of three sub-models: the Coalition Mission-Unit Allocation Model, the Coalition Mission-Support Model, and the Coalition Mission-Unit Grouping Model. The first sub-model is designed to find an optimized resource allocation by applying the shortest path problem and effectiveness functions. The second sub-model is developed to obtain an optimized logistics support plan by using the multi-commodity network flow. Finally, the third sub-model is designed to combine small units into one workable independent unit by using the quadratic assignment problem. The models are demonstrated with a notional humanitarian assistance operation

    A Multi-Attribute decision support system for allocation of humanitarian cluster resources , based on decision makers’ perspective

    The rush of the humanitarian suppliers into the disaster area proved to be counter-productive. To reduce this proliferation problem, the present research is designed to provide a technique for supplier ranking/selection in disaster response using the principles of utility theory. A resource allocation problem is solved using optimisation based on decision maker’s preferences. Due to the lack of real-time data in the first 72 h after the disaster strike, a Decision Support System (DSS) framework called EDIS is introduced to employ secondary historical data from disaster response in four humanitarian clusters (WASH: Water, Sanitation and Hygiene, Nutrition, Health, and Shelter) to estimate the demand of the affected population. A methodology based on multi-attribute decision-making (MADM), Analytical Hierarchy processing (AHP) and Multi-attribute utility theory (MAUT) provides the following results. First a need estimation technique is put forward to estimate minimum standard requirements for disaster response. Second, a method for optimization of the humanitarian partners selection is provided based on the resources they have available during the response phase. Third, an estimate of resource allocation is provided based on the preferences of the decision makers. This method does not require real-time data from the aftermath of the disasters and provides the need estimation, partner selection and resource allocation based on historical data before the MIRA report is released

    Assessing vulnerability and modelling assistance: using demographic indicators of vulnerability and agent-based modelling to explore emergency flooding relief response

    Get PDF
    Flooding is a significant concern for much of the UK and is recognised as a primary threat by most local councils. Those in society most often deemed vulnerable: the elderly, poor or sick, for example, often see their level of vulnerability increase during hazard events. A greater knowledge of the spatial distribution of vulnerability within communities is key to understanding how a population may be impacted by a hazard event. Vulnerability indices are regularly used – in conjunction with needs assessments and on-the-ground research – to target service provision and justify resource allocation. Past work on measuring and mapping vulnerability has been limited by a focus on income-related indicators, a lack of consideration of accessibility, and the reliance on proprietary data. The Open Source Vulnerability Index (OSVI) encompasses an extensive range of vulnerability indicators supported by the wider literature and expert validation and provides data at a sufficiently fine resolution that can identify vulnerable populations. Findings of the OSVI demonstrate the potential cascading impact of a flood hazard as it impacts an already vulnerable population: exacerbating pre-existing vulnerabilities, limiting capabilities and restricting accessibility and access to key services. The OSVI feeds into an agent-based model (ABM) that explores the capacity of the British Red Cross (BRC) to distribute relief during flood emergencies using strategies based upon the OSVI. A participatory modelling approach was utilised whereby the BRC were included in all aspects of the model development. The major contribution of this work is the novel synthesis of demographics analysis, vulnerability mapping and geospatial simulation. The project contributes to the growing understanding of vulnerability and response management within the NGO sector. It is hoped that the index and model produced will allow responder organisations to run simulations of similar emergency events and adjust strategic response plans accordingly

    A shortage risk mitigation model for multi-agency coordination in logistics planning

    We introduce a two-stage stochastic program to handle typical disaster preparedness activities under uncertainty from a multi-agency perspective. The model explicitly takes into account the number of people without healthcare attention, relief aid, and shelter support. We build a function that represents the total number of people at risk of not receiving proper humanitarian assistance using a bi-objective approach in which expected logistics costs are also minimized. The benefit of our approach is assessed through real flood cases in Mexico in which GIS analysis was used to enhance data gathering and to provide risk maps that could be potentially used by policy-makers in practical settings. The overall results suggest that sheltering decisions have to be closely coordinated with the management of material and human resources to avoid an increased number of people deprived of attention and relief aid. The Pareto Frontier also reveals that some solutions exhibit a quite interesting trade-off, e.g., it is possible to improve the overall relief assistance by almost 17% at the expense of less than 14% in the logistics costs

    Facility Location Planning in Relief Logistics: Decision Support for German Authorities

    Get PDF
    Disasters have devastating impacts on societies, affecting millions of people and businesses each year. The delivery of essential goods to beneficiaries in the aftermath of a disaster is one of the main objectives of relief logistics. In this context, selecting suitable locations for three different types of essential facilities is central: warehouses, distribution centers, and points of distribution. The present dissertation aims to improve relief logistics by advancing the location selection process and its core components. Five studies published as companion articles address substantial aspects of relief logistics. Despite the case studies\u27 geographical focus on Germany, valuable insights for relief logistics are derived that could also be applied to other countries. Study A addresses the importance of public-private collaboration in disasters and highlights the significance of considering differences in resources, capabilities, and strategies when using logistical models. Moreover, power differences, information sharing, and partner selection also play an important role. Study B elaborates on the challenges to identify candidate locations for warehouses, which are jointly used by public and private actors, and suggests a methodology to approach the collaborative warehouse selection process. Study C investigates the distribution center selection process and highlights that including decision-makers\u27 preferences in the objective function of location selection models helps to raise awareness of the implications of location decisions and increases transparency for decision-makers and the general population. Study D analyzes the urban water supply in disasters using a combination of emergency wells and mobile water treatment systems. Selected locations of mobile systems change significantly if vulnerable parts of the population are prioritized. Study E highlights the importance of accurate information in disasters and introduces a framework that allows determining the value of accurate information and the planning error due to inaccurate information. In addition to the detailed results of the case studies, four general recommendations for authorities are derived: First, it is essential to collect information before the start of the disaster. Second, training exercises or role-playing simulations with companies will help to ensure that planned collaboration processes can be implemented in practice. Third, targeted adjustments to the German disaster management system can strengthen the country\u27s resilience. Fourth, initiating public debates on strategies to prioritize parts of the population might increase the acceptance of the related decision and the stockpiling of goods for the people who know in advance that they will likely not receive support. The present dissertation provides valuable insights into disaster relief. Therefore, it offers the potential to significantly improve the distribution of goods in the aftermath of future disasters and increase disaster resilience

    The disaster area is a dynamic environment. The bottleneck in distributing the supplies may be from the damaged infrastructure or the unavailability of accurate information about the required amounts. The success of the disaster response network is based on collaboration, coordination, sovereignty, and equality in relief distribution. Therefore, a reliable dynamic communication system is required to facilitate the interactions, enhance the knowledge for the relief operation, prioritize, and coordinate the goods distribution. One of the promising innovative technologies is blockchain technology which enables transparent, secure, and real-time information exchange and automation through smart contracts. This study analyzes the application of blockchain technology on disaster management resilience. The influences of this most promising application on the disaster aid supply network resilience combined with the Internet of Things (IoT) and Dynamic Voltage Frequency Scaling (DVFS) algorithm are explored employing a network-based simulation. The theoretical analysis reveals an advancement in disaster-aids supply network strategies using smart contracts for collaborations. The simulation study indicates an enhance in resilience by improvement in collaboration and communication due to more time-efficient processing for disaster supply management. From the investigations, insights have been derived for researchers in the field and the managers interested in practical implementation

    Governance and Water Management: Progress and Tools in Mediterranean Countries

    Get PDF
    This paper reviews the progress with respect to Integrated Water Resource Management (IWRM) in Mediterranean countries, as addressed within the activities of the Nostrum-Dss project, a Coordination Action funded by the 6th Framework Programme of the EC, with a particular emphasis on the current use of decision support tools (DSS). The IWRM paradigm is a comprehensive management framework, which integrates the different aspects of water resources – from the underlying ecological and physical aspects, to the socio-economic values and needs (horizontal integration); and calls for increasing decentralisation and privatisation of water services (vertical integration), and the devolution of planning authority, without however forgetting the need to ensure equitable access to water resources. Substantial progress has been made in the last decades in Nostrum-Dss Partner countries, although a disparity can still be seen between the Northern and Southern banks. New institutions have been established for implementing IWRM, existing institutions have been reformed, and decision making processes increasingly require public participation. Decentralisation of decision making, implementation and monitoring are also well underway, although improvements are still needed to ensure that the traditional power structures do not prevail. More efficient technologies and infrastructures are in place, especially for the production of high value goods or in agriculture. Finally, several DSS have been developed: yet, while operational/technical DSS instruments have been successfully employed, DSSs tools developed in a participatory way, or tackling more complex, political as well as environmental and economic problems are still de-linked from actual decision making processes. Laws and regulations for water management in most Mediterranean countries embrace and support the paradigms of IWRM – and EU framework directives have played an important role in fostering this shift from more traditional, vertical governance to new, horizontal governance based on soft laws. Yet, the implementation of such laws and regulations is often only partial – often because of the lack of a clear monitoring and enforcement strategy, but also because of governments’ financial and human resources constraints. Strong overlaps of roles and competences among different government institutions remain, hampering effective implementation of water management. The tendency to centralisation of decision making persists, and actors’ involvement is scanty. The shift towards the use of demand side policies as opposed to supply side policies is not yet completed: yet, supply side policies are very costly, as they are based on greater mobilisation of financial resources. Full cost recovery pricing is not practiced widely. This reluctance to introduce full cost recovery pricing in developing countries may be due to ethical and moral considerations, but in developed countries it is often associated with strong lobbying power of interest groups. This study was supported by funding under the Sixth Research Framework of the European Union within the project "Network on Governance, Science and Technology for Sustainable Water Resource Management in the Mediterranean- The role of Dss tools” (NOSTRUM-Dss, contract number INCO-CT-2004-509158).Integrated Water Resources Management, Decision Support Systems, Environmental Governance
