The alkali/surfactant/polymer (ASP) flooding is a complex distributed parameter system (DPS). In this paper, an optimization model of ASP flooding is developed, which takes net present value (NPV) as the performance index, oil/water seepage continuity equations and adsorption diffusion equations of displacing agents as the governing equations, physicochemical algebraic equations and boundary conditions...
This study aims to solve the problems of urban road congestion caused by traffic accident with the premise that the accident scene is preserved. First, taking the definite length of the vehicle team as a fixed value and transforming the time issue that it has experienced into a transporting issue of sales volume. And then the corresponding optimization model is established. Finally, the method is...

An improved particle swarm optimization algorithm (PSO) combined with quantum genetic algorithm is proposed, to solve the problems that the PSO is difficult to converge for benchmark complex problems and it's parameters are hard to define. The new algorithm is used for submersible path planning and simulation on some standard test functions. The results show that the improved is superior to the standard...
This paper researches the optimization of injection strategies of polymer flooding in oil recovery. An optimal control problem (OCP) of a distributed parameter system (DPS) is established, in which the functional of performance index is profit maximum and the governing equations are the fluid equations in porous media. The control variables are chosen as the polymer concentrations and the switching...
