Approximations for the Two-Machine Cross-Docking Flow Shop Problem
We consider in this article the Two-Machine Cross-Docking Flow Shop problem, which is a special case of scheduling with typed tasks, where we have two types of tasks and one machine per type. Precedence constraints exist between tasks, but only from a task of the first type to a task of the second type. The precedence relation is thus a directed bipartite graph. Minimizing the makespan is stron...
متن کاملInverse scheduling: two-machine flow-shop problem
We study an inverse counterpart of the two machine flow-shop scheduling problem that arises in the context of inverse optimization. While in the forward scheduling problem all parameters are given and the objective is to find job sequence(s) for which the value of the makespan is minimum, in the inverse scheduling the exact values of processing times are unknown and they should be selected with...
متن کاملA Fuzzy Algorithm for the m-Machine, n-Job Flow Shop Sequencing Problem
Flow shop sequencing problem is included in NP-hard problems and a number of heuristic methods have been developed to solve it. Most of these methods are offered for the crisp processing time. However fuzzy algorithm is appropriate for the problems with fuzzy processing time. This paper presents a method in which an algorithm is used to minimize make span of flow shop with fuzzy processing time...

متن کاملThe two - machine flow shop problem with delays and the one - machine total tardiness problem
A partial order on a job set is called consistent, if it has a linear extension which is an optimal solution to the total tardiness problem of the job set. The concept of proper augmentations of consistent partial orders is based on Emmons' well-known dominance theorem. In this paper, we address the question whether the proper augmentation of a consistent partial order always results in a parti...
