This paper presents a hybrid discrete harmony search (DUS) algorithm for solving the blocking flow shop scheduling problem with the objective to minimize makespan. The proposed hybrid DUS algorithm utilizes discrete job permutations to represent harmonies and applies a job-permutation-based improvisation scheme to generate new harmonies. An initialization scheme based on a variant of the Minimum Blocking...
The harmony search (HS) algorithm is one of the recent evolutionary computation techniques to solve optimization problems. To make it applicable for lot-streaming flow shop problems, a discrete variant of the HS algorithm (DHS) with job permutations representation is proposed. In the proposed DHS algorithm, a new improvisation scheme is designed to generate feasible job sequences. A local search algorithm...
This paper proposes a novel discrete harmony search (DHS) algorithm to minimize makespan for a lot-streaming flow shop scheduling problem with sequence dependent setup times. Unlike the traditional harmony search (HS) algorithm, the proposed DHS algorithm utilizes job permutations to represent harmonies and applies a job-permutation-based improvisation to generate new harmonies. To enhance the algorithm's...
