Most of the metaheuristic algorithms for the no-wait flowshop scheduling problem with makespan criterion have adopted the O(n2) size insertion neighborhoods, and higher order (polynomial size) neighborhoods are seldom tried. However, higher order neighborhoods can improve the solution quality of metaheuristic algorithms. The paper presents a high order neighborhood with O(n4) size called nonadjacent...
An approach with decomposition on time windows is proposed to solve resource-constrained project scheduling problem (RCPSP) in this paper. This approach is to decompose the feasible space calculated by CPM of the original problem into some subspaces, which are searched using some schedule schema. Double justification is also performed in the search to improve the results. The results of experiments...
According to the bottleneck process- copper electroplating of the repair process for continuous casting crystallizer copper, a genetic algorithm is designed to solve its scheduling problem, including the coding, the decoding, the crossover and mutation. Through the analysis of simulation experiments, compared with the use of the manual mode and the heuristic algorithm, the genetic algorithm shows...
