Storage or buffer capacities between successive machines in flowshop problems may be unlimited, limited or null. Two last cases can lead to blocking situations. In flowshop scheduling literature, many studies and research were realized about classical flowshop problem and also about some problems with only one blocking situation. This paper deals with makespan minimization in flowshop schedulin...

In the field of scheduling, the flowshop problems have been thoroughly studied over the last six decades. In this paper we propose a concise overview of flowshop scheduling techniques evolved during this period. We surveyed the exact, heuristics and metaheuristics methods for solving various flowshop scheduling problems. As a result various optimization techniques, solution procedures are avail...

We consider a variant of no-wait flowshop scheduling that is motivated by continuous casting in the multistage production process in steel manufacturing. The task is to find a feasible schedule with a minimum number of interruptions, i.e., continuous idle time intervals on the last production stage. Based on an interpretation as Eulerian Extension Problems, we fully settle the complexity status...

In this researcha particle swarm optimization (PSO) algorithm is proposedfor no-wait flowshopsequence dependent setuptime scheduling problem with weighted earliness-tardiness penalties as the criterion ( | , | ∑ " ).The smallestposition value (SPV) rule is applied to convert the continuous value of position vector of particles in PSO to job permutations.A timing algorithm is generated to find t...

This paper addresses the multistage hybrid flow shop (HFS) scheduling problems. The HFS is the special case of flowshop problem. Multiple parallel machines are considered in each stage in the HFS. The HFS scheduling problem is known to be strongly NPhard. Hence, many researchers proposed metaheuristic algorithms for solving the HFS scheduling problems. This paper develops a bat algorithm (BA) t...

In this paper, an integrated multilevel, control-theoretic framework has been proposed for effectively handling integration of planning, scheduling, and rescheduling. A general resourceconstrained, multistage, multiproduct plant operating as a hybrid flowshop facility has been considered. The proposed approach is based on the inherent hierarchical decomposition of the overall decision-making pr...

In this paper, we consider a manufacturing system with two-machine no-wait flowshop scheduling problem where setup times are uncertain. The the performance measure of maximum lateness was addressed in literature (Computational and Applied Mathematics 37, 6774-6794) dominance relations were proposed. We establish new relation show that is, on average, about 90$ \% $ more efficient than existing ...
