MILP Formulation and Genetic Algorithm for Non-permutation Flow Shop Scheduling Problem with Availability Constraints
In this paper, we consider a flow shop scheduling problem with availability constraints (FSSPAC) for the objective of minimizing the makespan. In such a problem, machines are not continuously available for processing jobs due to preventive maintenance activities. We proposed a mixed-integer linear programming (MILP) model for this problem which can generate non-permutation schedules. Furthermor...
متن کاملTight Bounds for Permutation Flow Shop Scheduling
In flow shop scheduling there are m machines and n jobs, such that every job has to be processed on the machines in the fixed order 1, . . . , m. In the permutation flow shop problem, it is also required that each machine processes the set of all jobs in the same order. Formally, given n jobs along with their processing times on each machine, the goal is to compute a single permutation of the j...
متن کاملDominance properties for permutation flow shop problems
We are interested here in new sub cases for which permutation flow shop schedules are dominant while considering the classical flow shop scheduling problem and the makespan criterion. To obtain these sub cases, we introduce conditions on the lower and upper bounds of the processing times. These conditions can be quite realistic when the corresponding line is balanced.
متن کاملPermutation and non-permutation schedules for the flowline manufacturing cell with sequence dependent family setups
Through the use of an effective simulated annealing algorithm, this paper presents an extensive computational investigation concerning the performance evaluation of non-permutation vs. permutation schedules for the flowline manufacturing cell with sequence dependent setup times. The results show that there are significant improvements made by using non-permutation schedules over permutation sch...
متن کاملApplying Iterated Local Search to the Permutation Flow Shop Problem
Iterated local search (ILS) is a general and powerful metaheuristic which provides an easily implementable way of improving the performance of local search algorithms. In this article we consider the application of ILS to the permutation flow shop problem (FSP), a strongly studied problem in machine scheduling. We experimentally investigate the effect of specific implementation choices in our I...
