How to choose optimisation solver?5 answersWhen choosing an optimization solver, it is important to consider the specific requirements of the problem at hand. While there are many optimization algorithms available, not all of them are guaranteed to find the global optimum or produce precise results. However, optimization methods are still commonly used, even when not necessary. One approach to developing an optimizer is to use a lookup table based on pre-computed solutions, which can lead to faster and more effective performance on new instances. Another strategy is to identify search space reduction methods, such as symmetry breaking strategies, which can significantly improve the computational time of solvers. Additionally, algorithm selection systems can be used to automatically find the best optimization algorithm based on the features of the problem landscape. These insights provide guidance for choosing an optimization solver based on the specific problem requirements.
How make a optimisation opération?1 answersAn operation optimization method can be achieved by following certain steps. First, obtain the necessary parameters related to the operation cost and production discharge of the system. Then, establish models based on these parameters, such as an operation cost model and a production discharge model. Next, solve these models using particle swarm optimization to obtain optimized results. Another approach involves correlating the equipment efficiency with the equipment load rate based on data fitting. This correlation is then used to establish a model for operation optimization, with the objective of minimizing operation cost. In the case of a heated oil pipeline, an optimization model is proposed considering various constraints, such as thermodynamic, hydraulic, and strength constraints. This model is solved using a combination of linear approximation and simplex methods. Finally, an operation optimization method for a terminal involves determining the progress of background operations and optimizing them based on certain criteria.
