This paper deals with the cyclic scheduling of flexible job-shop with time window constraints and resource capacity constraints. For time window constraints, the duration for processing products on machines and the duration for translating products from one machine to another by transfers are taken into account; for the resource capacity constraints, the confined operation space of machines and...
This paper addresses minimizing Total Weighted Earliness/Tardiness (TWET) of jobs in a Flexible Job Shop (FJS) problem. The FJS problem is an extension of the classical Job Shop (JS) problem that implies each operation may be assigned to alternative available machines. So, a job may have alternative routing. The FJS problem with a TWET criterion is modeled as a mixed integer programming. The mo...
An NP-hard problem like Flexible Job Shop Scheduling (FJSP) tends to be more complex and requires computational effort optimize the objectives with contradictory measures. This paper aims address FJSP combined objectives, minimization of make-span, maximum workload, total workload. proposes ‘Hybrid Adaptive Firefly Algorithm’ (HAdFA), a new enhanced version classic Algorithm (FA) embedded adapt...
The multi-objective flexible job shop scheduling in a cellular manufacturing environment is challenging real-world problem. This recently introduced problem variant considers exceptional parts, intercellular moves, transportation times, sequence-dependent family setup and recirculation requiring minimization of makespan total tardiness, simultaneously. A previous study shows that the exact solv...
Firefly Algorithm (FA) is a nature-inspired optimization algorithm that can be successfully applied to continuous optimization problems. However, lot of practical problems are formulated as discrete optimization problems. In this paper a hybrid discrete firefly algorithm (HDFA) is proposed to solve the multi-objective flexible job shop scheduling problem (FJSP). FJSP is an extension of the clas...
