Повний текст джерелаThe topic of this thesis is about the optimization of portfolio of defaultable assets. The subprime crisis show us that in the future, we should deal with the default risk to get the real value of the portfolio. In fact, there are so many exchanges in the markets that the financial market become a network with many connections and we should identity it to understand the real risk that we take when we deal with financial assets. In this thesis; we define a financial system with a finite number of connections and we give a model for the dynamics of the asset in such system considering the connections in the network. We deal with the jumps intensity processes to take account the correlation in the network. Using Backward Stochastic Differential Equations (BSDE), we get the price of a contingent claim and we consider the model risk to get the optimal consumption and terminal wealth in such financial network

Повний текст джерелаHydropower is the main renewable energy produced in France. It brings both an energy reserve and a flexibility, of great interest in a contextof penetration of intermittent sources in the production of electricity. Its management raises difficulties stemming from the number of dams, from uncertainties in water inflows and prices and from multiple uses of water. This Phd thesis has been realized in partnership with Electricité de France and addresses two hydropower management issues, modeled as stochastic dynamic optimization problems. The manuscript is divided in two parts. In the first part, we consider the management of a hydroelectric dam subject to a so-called tourist constraint. This constraint assures the respect of a given minimum dam stock level in Summer months with a prescribed probability level. We propose different original modelings and we provide corresponding numerical algorithms. We present numerical results that highlight the problem under various angles useful for dam managers. In the second part, we focus on the management of a cascade of dams. We present the approximate decomposition-coordination algorithm called Dual Approximate Dynamic Programming (DADP). We show how to decompose an original (large scale) problem into smaller subproblems by dualizing the spatial coupling constraints. On a three dams instance, we are able to compare the results of DADP with the exact solution (obtained by dynamic programming); we obtain approximate gains that are only at a few percents of the optimum, with interesting running times. The conclusions we arrived at offer encouraging perspectives for the stochastic optimization of large scale problems

Повний текст джерелаThe aim of our work is the study of probabilistic models and the design of tools and statistical methods in order to optimize industrial maintenance process, taking into account Reliability, Quality and Availability. After a careful modelling of the most common life-cycle function (namely the "Bath-Curve"), an optimal frequency of replacement is determined using a "self-adaptive" Simulation method. A complexity study lead us to use a numerical method, based on evolutionary algorithm, in order to optimize stock management in case of hazardous material requisition. Through an analysis of the standards of production: stops, an heuristical method allows us to optimize maintenance policy in the context of opportunistic maintenance. Thinking about financial risk assessment, we integrate imperfect knowledge of life-cycle function and supplies process in all methods developed above

Повний текст джерелаSurface water quality impairment is primarily caused by phosphorus (P) lost from surrounding agricultural fields. This knowledge triggered the development of P losses predicting tools taking into account transport and source factors. In the United States, a great number of P index (PI) approaches has been developed and adopted. Because these PIs are not necessarily applicable in the province of Québec, a P index specific to Québec has been developed : the Phosphorus Risk Index (PRI). The objective of this research was to validate and possibly improve the PRI method using P losses measured on nine experimental agricultural plots located on the IRDA farm in Saint-Lambert-de-Lauzon. For each plot, P losses and the amounts of water from runoff and tile-drainage were continuously measured during a two-year period (2001-2002) using automated systems. The total P losses were on average 540 g ha-1 from which 95% was exported via the subsurface drainage system. For each plots, the selected P loss value of each of the PRI components were multiplied by the weight assigned to each components and summed to obtain the final PRI value which is associated to one of the five P loss ratings (i.e. very low, low, medium, high and very high). Results indicate that the measured total P losses and PRI values showed a correlation coefficient of 0.63. In order to improve the relationship between P losses and the IRP, the Trust-region algorithm of the SAS none-linear programming (proc. NLP) was used to optimize weights and P loss potential values of the components. Optimization resulted in a correlation coefficient of 0.92. Modifications to the method kept the additive structure of the PRI method. Results were only valid for the Saint-Lambert plots. Generalization across Québec would require experiments on a range of soil, climate, and agronomic conditions. Results from this research indicated possible improvement in the predictive accuracy of the PRI method. Keywords: Phosphorus index, phosphorus losses, optimization, risk assessment, source factors, transport factors.

Повний текст джерелаTrade liberalization, the development of mean of transport and the development economic of emerging countries which lead to globalization of supply chain is irreversible phenomen. They can reduce costs, in return, they multiply the risk of disruption from upstream stage to downstream stage. In this thesis, we focus on the inbound supply chain stage. We treat more specifically the case of a purchasing central to select suppliers and allocate the orders. Each of the suppliers cannot deliver its orders due to internal reasons (poor quality problems) or external reasons (natural disasters, transport problems). According to the selected suppliers deliver their orders or not, the transaction operation will generate a profit or loss. The objective of this thesis is to provide decision support tools to a decision maker faced with this problem by taking into account the behavior of decision maker toward risk. We proposed stochastic mixed integer linear programs to model this problem. In the first part, we focuses on the development of a decision support visual tool that allows a decision maker to find a compromise between maximizing the expected profit and minimize the risk of loss. In the second part, we integrated the techniques of estimation of risk VaR and CVaR in this problem. The objective is to help decision maker to minimize the expected cost and minimize the conditional value at risk simultanously via calculating of VaR. Result shows that the decision maker must tack into account the different scenarios of disruption regardless their probability of realisation

Повний текст джерелаThis thesis concentrates on the optimization of large-scale management policies under conditions of risk and uncertainty. In paper I, we address the problem of solving large-scale spatial and temporal natural resource management problems. To model these types of problems, the framework of graph-based Markov decision processes (GMDPs) can be used. Two algorithms for computation of high-quality management policies are presented: the first is based on approximate linear programming (ALP) and __ the second is based on mean-field approximation and approximate policy iteration (MF-API). The applicability and efficiency of the algorithms were demonstrated by their ability to compute near-optimal management policies for two large-scale management problems. It was concluded that the two algorithms compute policies of similar quality. However, the MF-API algorithm should be used when both the policy and the expected value of the computed policy are required, while the ALP algorithm may be preferred when only the policy is required. In paper II, a number of reinforcement learning algorithms are presented that can be used to compute management policies for GMDPs when the transition function can only be simulated because its explicit formulation is unknown. Studies of the efficiency of the algorithms for three management problems led us to conclude that some of these algorithms were able to compute near-optimal management policies. In paper III, we used the GMDP framework to optimize long-term forestry management policies under stochastic wind-damage events. The model was demonstrated by a case study of an estate consisting of 1,200 ha of forest land, divided into 623 stands. We concluded that managing the estate according to the risk of wind damage increased the expected net present value (NPV) of the whole estate only slightly, less than 2%, under different wind-risk assumptions. Most of the stands were managed in the same manner as when the risk of wind damage was not considered. However, the analysis rests on properties of the model that need to be refined before definite conclusions can be drawn

Повний текст джерелаWe consider stochastic optimization and game theory problems with risk measures. In a first part, we focus on time consistency. We begin by proving an equivalence between time consistent mappings and the existence of a nested formula. Motivated by well-known examples in risk measures, we investigate three classes of mappings: translation invariant, Fenchel-Moreau transform and supremum mappings. Then, we extend the concept of time consistency to player consistency, by replacing the sequential time by any unordered set and mappings by any relations. Finally, we show how player consistency relates to sequential and parallel forms of decomposition in optimization. In a second part, we study how risk measures impact the multiplicity of equilibria in dynamic game problems in complete and incomplete markets. We design an example where the introduction of risk measures leads to the existence of three equilibria instead of one in the risk neutral case. We analyze the ability of two different algorithms to recover the different equilibria. We discuss links between player consistency and equilibrium problems in games. In a third part, we study distribution ally robust optimization in machine learning. Using convex risk measures, we provide a unified framework and propose an adapted algorithm covering three ambiguity sets discussed in the literature

Повний текст джерелаThis thesis presents methods for estimation and optimization of stochastic black box functions. Motivated by the necessity to take risk-averse decisions in medecine, agriculture or finance, in this study we focus our interest on indicators able to quantify some characteristics of the output distribution such as the variance or the size of the tails. These indicators also known as measure of risk have received a lot of attention during the last decades. Based on the existing literature on risk measures, we chose to focus this work on quantiles, CVaR and expectiles. First, we will compare the following approaches to perform quantile regression on stochastic black box functions: the K-nearest neighbors, the random forests, the RKHS regression, the neural network regression and the Gaussian process regression. Then a new regression model is proposed in this study that is based on chained Gaussian processes inferred by variational techniques. Though our approach has been initially designed to do quantile regression, we showed that it can be easily applied to expectile regression. Then, this study will focus on optimisation of risk measures. We propose a generic approach inspired from the X-armed bandit which enables the creation of an optimiser and an upper bound on the simple regret that can be adapted to any risk measure. The importance and relevance of this approach is illustrated by the optimization of quantiles and CVaR. Finally, some optimisation algorithms for the conditional quantile and expectile are developed based on Gaussian processes combined with UCB and Thompson sampling strategies
