| 发明名称 | Automatic calibration of a model for a complex flow system | ||
| 摘要 | Aspects of the present invention provide a solution for calibrating a model of a complex flow system. In an embodiment, a comparison is made between the output from the model and a set of observed values for each of a plurality of nodes in the complex flow system. An adjoint sensitivity is computed for each of the nodes based on the comparison. These computed adjoint sensitivities are used to adjust a set of coefficients of the models. This calibration process can be performed multiple times, periodically and/or continuously to maximize the accuracy of the model. | ||

| 主权项 | 1. A method for calibrating a model of a complex flow system, comprising: making a comparison between an output from the model and an observed value for a node of a plurality of nodes in the complex flow system; computing an adjoint sensitivity for the node based on the comparison; and adjusting a set of coefficients of the model associated with the node based on the adjoint sensitivity, wherein the complex flow system includes a flow of water in a river system and wherein the set of coefficients includes a capacity coefficient, a slope coefficient and a friction coefficient. | ||
