The work presented in this Ph.D dissertation is motivated by the problem of management of a fleet of cargos transporting lique ed natural gas (LNG) initially proposed by Total. The holder of the portfolio has to meet its commitments towards its counterparts while trying to generate pro ts through arbitrating different commodities market. Thus, the management of portfolio can be modeled as a stochastic, dynamic and integer optimization problem. This Ph.D dissertation is organised as follows: 1 We introduce a numerical method for solving continuous relaxation problem. We propose an algorithm based on the combination of the vectorial quantization method as discretization method and the dual dynamic programming approach. We show the convergence...
