In order to solve scheduling scheme of multiple supply points to provide a variety of emergency supplies for multiple hit points under large-scale disasters efficiently, after summarizing the existing research, mathematical model is constructed with the objective to minimize emergency response start time and the number of supply points, and a genetic algorithm to obtain optimal solution is designed...
PSO is a parallel stochastic optimization algorithm with advantages of less parameters and high efficiency. This paper describes the programming problem in the method of two linear tables with discrete and continuous quantity, then uses discrete PSO algorithm to discrete optimization and continuous PSO to optimize continuous quantity in the solving process respectively, based on these proposes the...
In order to improve particle swarm optimization (PSO) to solve complex and large scale discrete optimization problems, the paper introduces an improved discrete particle swarm optimization (IDPSO) based on edge coding and multilevel reduction strategy. First, redefine the velocity and position of the particle based on edge-coding, and adopted converted insertion of the edge to update the information...
