In this paper, a multi-objective particle swarm optimization algorithm with a new global best (gbest) selection strategy is proposed for dealing with multi-objective problems. In multi-objective particle swarm optimization, gbest plays an important role in convergence and diversity of solutions. A K-means algorithm and proportional distribution based approach is used to select gbest from the ar...

In this paper, we present a particle swarm optimization for multi-objective job shop scheduling problem. The objective is to simultaneously minimize makespan and total tardiness of jobs. By constructing the corresponding relation between real vector and the chromosome obtained by using priority rule-based representation method, job shop scheduling is converted into a continuous optimization pro...

This paper firstly presents a novel constraint-handling technique , called dynamicobjective method (DOM), based on the search mechanism of the particles of particle swarm optimization (PSO). DOM converts the constrained optimization problem into a bi-objective optimization problem, and then enables each particle to dynamically adjust its objectives according to its current position in the searc...
