This paper addresses the problem of computing minimum risk paths by taking as objective the expected accident cost. The computation is based on a dynamic programming formulation which can be considered an extension of usual dynamic programming models: path costs are recursively computed via functions which are assumed to be monotonic. A large part of the paper is devoted to analyze in detail th...
Stochastic weather generators are widely used in different fields such as hydrological applications, environmental management and agricultural risk assessments. In this study, a popular stochastic weather generator, LARS-WG, was used in relation to reproduce observed statistical properties, including, means and variances of monthly precipitation, maximum temperature, minimum temperature and sol...
