Lexicographic optimisation for water resources planning: the case of Lake Verbano, Italy

In Proceedings of the iEMSs First Biennial Meeting: Integrated Assessment and Decision Support (2002), pp. 235-240


Lake Verbano is a natural lake used as multipurpose reservoir. The lake supplies water for irrigation and hydropower generation to downstream users, while flood controls are applied to protect the lake shores and the downstream populations on the Ticino river, and environmental preservation constraints must be respected. All these objectives are conflicting and they have different priorities, as stated by the Italian regulation on water use. This paper explores a methodology aimed at solving this conflict. The stakeholders involvement in the ...


Building Rothermel fire behaviour fuel models by genetic algorithm optimisation

International Journal of Wildland Fire, Vol. 24, No. 3. (2015), 317,


A method to build and calibrate custom fuel models was developed by linking genetic algorithms (GA) to the Rothermel fire spread model. GA randomly generates solutions of fuel model parameters to form an initial population. Solutions are validated against observations of fire rate of spread via a goodness-of-fit metric. The population is selected for its best members, crossed over and mutated within a range of model parameter values, until a satisfactory fitness is reached. We showed that GA improved the performance ...


Is robustness really robust? How different definitions of robustness impact decision-making under climate change

Climatic Change, Vol. 135, No. 3-4. (2016), pp. 409-424,


Robust decision-making is being increasingly used to support environmental resources decisions and policy analysis under changing climate and society. In this context, a robust decision is a decision that is as much as possible insensitive to a large degree of uncertainty and ensures certain performance across multiple plausible futures. Yet, the concept of robustness is neither unique nor static. Multiple robustness metrics, such as maximin, optimism-pessimism, max regret, have been proposed in the literature, reflecting diverse optimistic/pessimistic attitudes by the decision ...


Keep it complex

Nature, Vol. 468, No. 7327. (23 December 2010), pp. 1029-1031,


When knowledge is uncertain, experts should avoid pressures to simplify their advice. Render decision-makers accountable for decisions, says Andy Stirling. ...


The development of environmental thinking in economics

Environmental Values, Vol. 8, No. 4. (November 1999), pp. 413-435,


There has always been a sub-group of established economists trying to convey an environmental critique of the mainstream. This paper traces their thinking into the late 20th century via the development of associations and journals in the USA and Europe. There is clearly a divergence between the conformity to neo-classical economics favoured by resource and environmental economists and the acceptance of more radical critiques apparent in ecological economics. Thus, the progressive elements of ecological economics are increasingly incompatible with those practising ...


Web distributed computing for evolutionary training of artificial neural networks

In Proceedings of the International Conference on Information Technologies (InfoTech-2016) (September 2016), pp. 210-216


Evolutionary algorithms (EAs) are widely used in artificial neural networks training. EAs are computationally interesting because it is possible ot separate the problem solving in smaller pieces and to calculate these smaller pieces on different machines (distributed computing). Distributed computing platforms are well established and the most popular is BOINC, created in Berkeley. The problem in distributed computing platforms is the heterogeneity of the computational environment. The best way for solving heterogeneity is by using well established technology such as AJAX. ...

The Neighbor Search approach applied to reservoir optimal operation: the Hoa Binh case study

No. hal-00698200. (2006)


[Conclusion] The focus of this thesis is to show, through a real-case application, how the NS can be useful to improve the decision-making process for multi-objectives reservoir operation planning. After a survey of the principal techniques employed in literature to solve such problems, the NS algorithm has been discussed. Further, the case-study has been presented. Hoa Binh is the largest reservoir in Vietnam, providing 40% of its total power supplies and protecting the capital Hanoi from major flooding events. This double purpose generates conflicts in its management ...

Using ROC Curves to Choose Minimally Important Change Thresholds when Sensitivity and Specificity Are Valued Equally: The Forgotten Lesson of Pythagoras. Theoretical Considerations and an Example Application of Change in Health Status

PLoS ONE, Vol. 9, No. 12. (4 December 2014), e114468,


[Background] Receiver Operator Characteristic (ROC) curves are being used to identify Minimally Important Change (MIC) thresholds on scales that measure a change in health status. In quasi-continuous patient reported outcome measures, such as those that measure changes in chronic diseases with variable clinical trajectories, sensitivity and specificity are often valued equally. Notwithstanding methodologists agreeing that these should be valued equally, different approaches have been taken to estimating MIC thresholds using ROC curves. [Aims and objectives] We aimed to compare the different approaches used with ...


Remarks on a recent paper on the "no free lunch" theorems

Evolutionary Computation, IEEE Transactions on In Evolutionary Computation, IEEE Transactions on, Vol. 5, No. 3. (June 2001), pp. 295-296,


This note discusses the recent paper "Some technical remarks on the proof of the no free lunch theorem" by Koppen (2000). In that paper, some technical issues related to the formal proof of the no free lunch (NFL) theorem for search were given by Wolpert and Macready (1995, 1997). The present authors explore the issues raised in that paper including the presentation of a simpler version of the NFL proof in accord with a suggestion made explicitly by Koppen (2000) and ...


No free lunch theorems for optimization

Evolutionary Computation, IEEE Transactions on, Vol. 1, No. 1. (06 April 1997), pp. 67-82,


A framework is developed to explore the connection between effective optimization algorithms and the problems they are solving. A number of “no free lunch” (NFL) theorems are presented which establish that for any algorithm, any elevated performance over one class of problems is offset by performance over another class. These theorems result in a geometric interpretation of what it means for an algorithm to be well suited to an optimization problem. Applications of the NFL theorems to information-theoretic aspects of optimization ...


A Decision-Theoretic Model of Assistance

Journal of Artificial Intelligence Research, Vol. 50 (2014), pp. 71-104,


There is a growing interest in intelligent assistants for a variety of applications from sorting email to helping people with disabilities to do their daily chores. In this paper, we formulate the problem of intelligent assistance in a decision-theoretic framework, and present both theoretical and empirical results. We first introduce a class of POMDPs called hidden-goal MDPs (HGMDPs), which formalizes the problem of interactively assisting an agent whose goal is hidden and whose actions are observable. In spite of its restricted ...


Ecological Optimization and Adaptive Management

Annual Review of Ecology and Systematics, Vol. 9, No. 1. (1978), pp. 157-188,


Over the last two decades a large body of literature on control and optimization of dynamic systems has developed. There have been attempts to apply some of the concepts and techniques to problems in resource ecology, particularlyin relation to harvesting policies for exploited populations. This review seeks to provide a non-mathematical overview with emphasis on the anatomy of optimization formulations, the technical problems of obtaining solutions, and the prospects for good decision making in the face of uncertainty. Uncertainty is a pervasive feature of ecological management problems. ...

Decision Support Systems, Vol. 16, No. 2. (February 1996), pp. 103-117,


A general framework and a specific implementation of a software environment for model prototyping, simulation and optimization are presented. The integration of simulation and optimization, and the possibility of comparing experimental results under complete user control represent the central parts of the proposed approach. Optimization is performed by repetitive simulation runs under the control of an optimization method. The integration of simulation and optimization as well as the post processing facilities offer an effective support to the classical phases of the ...


Computer science and parsimony: a reappraisal, with discussion of methods for poorly structured datasets

Cladistics (1 June 2014), pp. n/a-n/a,


In recent years, several publications in computer science journals have proposed new heuristic methods for parsimony analysis. This contribution discusses those papers, including methods highly praised by their authors, such as Hydra, Sampars and GA + PR + LS. Trees of comparable or better scores can be obtained using the program TNT, but from one to three orders of magnitude faster. In some cases, the search methods are very similar to others long in use in phylogenetics, but the enormous speed differences seem to correspond ...


Deeply incised submarine glacial valleys beneath the Greenland ice sheet

Nature Geosci, Vol. 7, No. 6. (18 June 2014), pp. 418-422,


The bed topography beneath the Greenland ice sheet controls the flow of ice and its discharge into the ocean. Outlet glaciers move through a set of narrow valleys whose detailed geometry is poorly known, especially along the southern coasts1, 2, 3. As a result, the contribution of the Greenland ice sheet and its glaciers to sea-level change in the coming century is uncertain4. Here, we combine sparse ice-thickness data derived from airborne radar soundings with satellite-derived high-resolution ice motion data through ...


Assessment of soil erosion vulnerability in western Europe and potential impact on crop productivity due to loss of soil depth using the ImpelERO model

Agriculture, Ecosystems & Environment, Vol. 81, No. 3. (November 2000), pp. 179-190,


Soil erosion continues to be a major concern for the development of sustainable agricultural management systems. Sustainability modelling analysis for soil erosion must include not only vulnerability prediction but also address impact and response assessment, in an integrated way. This paper focuses on the impact of soil erosion on crop productivity and the accommodation of agricultural use and management practices to soil protection. From the Andalucia region in Spain, soil/slope, climate and crop/management information was used to further develop an expert-system/neural-network ...


Floods in a changing climate



"Flood risk management is presented in this book as a framework for identifying, assessing and prioritizing climate-related risks and developing appropriate adaptation responses. Rigorous assessment is employed to determine the available probabilistic and fuzzy set-based analytic tools, when each is appropriate and how to apply them to practical problems. Academic researchers in the fields of hydrology, climate change, environmental science and policy and risk assessment, and professionals and policy-makers working in hazard mitigation, water resources engineering and environmental economics, will find ...


Land use optimization in watershed scale

Land Use Policy, Vol. 26, No. 2. (April 2009), pp. 186-193,


Managing a watershed for satisfying the inhabitant's demand is a difficult task if one has to maintain a reasonable balance between usually conflicting environmental flows and demands. The solution to these complex issues requires the use of mathematical techniques to take into account conflicting objectives. Many optimization models exist for general management systems but there is a knowledge gap in linking practical problems with the optimum use of all land resources under conflicting demands in a watershed. In the present study, ...


Reservoir-system simulation and optimization techniques

Stochastic Environmental Research and Risk Assessment In Stochastic Environmental Research and Risk Assessment, Vol. 27, No. 7. (2013), pp. 1751-1772,


Reservoir operation is one of the challenging problems for water resources planners and managers. In developing countries the end users are represented by the water sectors in most parts and conflict over water is resolved at the agency level. This paper discusses an overview of simulation and optimization modeling methods utilized in resolving critical issues with regard to reservoir systems. In designing a highly efficient as well as effective dam and reservoir operational system, reservoir simulation constitutes one of the most ...

Optimal Flow Allocation in the Zambezi River System

Water Resources Management In Water Resources Management, Vol. 11, No. 5. (1997), pp. 377-393,


The optimal flow allocation in the Zambezi system, the largest multi-reservoir water resources system in southern Africa, is analysed. The problem is formulated in network terms and solved with a network flow algorithm. The present configuration of the system is taken as the reference to evaluate the benefits of the proposed modifications to the existing hydropower schemes. The introduction of additional operational constraints is also considered in order to analyse the costs of environmental protection of paludal ecosystems and to account ...


Uncertainty in Self-Adaptive Software Systems

Lecture Notes in Computer Science In Software Engineering for Self-Adaptive Systems II, Vol. 7475 (2013), pp. 214-238,


The ever-growing complexity of software systems coupled with their stringent availability requirements are challenging the manual management of software after its deployment. This has motivated the development of self-adaptive software systems. Self-adaptation endows a software system with the ability to satisfy certain objectives by automatically modifying its behavior at runtime. While many promising approaches for the construction of self-adaptive software systems have been developed, the majority of them ignore the uncertainty underlying the adaptation. This has been one of the key ...


Set-valued control laws in minmax control problem

In Modeling and control in environmental issues (2002)


The aim of this paper is to find a set-valued control policy and a set of initial states that are solutions of a minmax optimal control problem. The control problem is applied to a periodic discrete-time dynamic system, affected by disturbances characterized by a set-membership description. The functional to be minimized is the maximum cost per step that may occur under the worst combination of disturbances. ...


Optimal Environmental Management in the Presence of Irreversibilities

Journal of Economic Theory, Vol. 96, No. 1-2. (January 2001), pp. 180-207,


We consider an environment of a fixed size that can be converted to another use. This conversion can be made in steps, but it is irreversible. The future benefits (per unit) from the original use, and from the alternative use, follow a diffusion process. For a fairly general case, we show that the value function must be the unique (viscosity) solution to the associated Hamilton-Jacobi-Bellman equation. We also exhibit several properties of the solution for the case of constant relative risk ...


A review of operations research methods applicable to wildfire management

International Journal of Wildland Fire, Vol. 21, No. 3. (2012), 189,


Across the globe, wildfire-related destruction appears to be worsening despite increased fire suppression expenditure. At the same time, wildfire management is becoming increasingly complicated owing to factors such as an expanding wildland–urban interface, interagency resource sharing and the recognition of the beneficial effects of fire on ecosystems. Operations research is the use of analytical techniques such as mathematical modelling to analyse interactions between people, resources and the environment to aid decision-making in complex systems. Fire managers operate in a highly challenging ...


On-line design of water reservoir policies based on inflow prediction

IFAC-PapersOnLine In Proceedings of the 17th IFAC World Congress, Vol. 41, No. 2. (06 July 2008), pp. 14540-14545,


Stochastic Dynamic Programming (SDP) is the method most extensively adopted to design release policies for water reservoir networks. However, it suffers of the well known "curse of dimensionality", which actually limits its applicability to small reservoir networks. In this paper we present an on-line approach to policy design that not only constitutes a viable alternative to overcome the SDP limits, but can also be used with an inflow predictor to improve the performance of SDPbased off-line policies. This latter possibility is ...


System-of-Systems hierarchy of biodiversity conservation problems

Ecological Modelling, Vol. 235-236 (June 2012), pp. 36-48,


Many natural and man-made systems influence the well-being and sustainability of a country. The state of biodiversity, water, air, and land are examples of the former whereas health, education, economy, and policies are examples of the latter. These systems are extremely involved and hard to model. To overcome some of the difficulties a System-of-Systems (SoS) approach is adopted. This paper models biodiversity as a SoS at various levels of organization, and each level is in turn modeled according to existing knowledge ...


Investigating the optimality of proactive management of an invasive forest pest

In The future of high-elevation, five-needle white pines in Western North America: Proceedings of the High Five Symposium (2011), pp. 295-302


This paper offers a preliminary investigation into the conditions under which it might be optimal to engage in proactive management of a non-timber forest resource in the presence of an invasive species whose spread is unaffected by management action. Proactive management is defined as treating an uninfected area to encourage healthy ecosystem function, given that the arrival of the invasive is inevitable. Inspired by the problem of white pine blister rust in the Rocky Mountain west of the United States, the ...


Ethics in OR/MS: past, present and future

4OR: A Quarterly Journal of Operations Research, Vol. 2, No. 2. (1 July 2004), pp. 95-110,


The pervasiveness and impact on society and on every day human life of technology has led to a growing awareness that science and technology cannot be considered above or beyond the realm of value judgements and hence of ethics. This is especially true for Operations Research / Management Science (OR/MS), that particular science which is concerned with methodologies for scientifically deciding how to design and operate man-machine systems in an optimal way, usually under conditions requiring the allocation of scarce resources. ...


Choosing among infinite alternatives

In Integrated and participatory water resources management theory (2007), pp. 223-242


In Chapter 7 we understood that, even when the Decision Maker (DM) is acting in conditions of full rationality, the design of the alternatives poses three difficulties: the presence of infinite alternatives; the presence of uncertainty produced by random disturbances; and the presence of recursive decisions. In this chapter, we begin to describe the tools to overcome these difficulties by analysing the Design Problem in the simplest of cases: the case in which the actions being considered are all planning actions ...
