Further, products can be split into several sublots to allow overlapping production in a two-stage hybrid flow shop wherein various identical, capacitated machines operate in parallel at each stage. We present a mixed-integer linear program (MILP) for this integrated batching and lot streaming ...
(1) The coordinated two-stage hybrid flow shop scheduling on parallel batching machines considering the job-dependent deteriorating effect and non-identical job sizes is first investigated in this paper. (2) For the single parallel batching problem, we first propose a three-dimensional wasted volume...
jobs to parallel machines at each stage; and (b) sequencing the jobs allocated to each machine. Note that the two decisions are a combination of those of the parallel machine and the reentrant flow shop scheduling problems. The objective is to minimize makespan, which is directly related ...
Setup times are implemented between jobs in both stages and between levels in stage one. There has not been any study about this real area which has two separated stages with different setup times in each one. Because of the intractability of the reentrant hybrid flow shop model, some ...
This research investigates a two-stage no-wait hybrid flow-shop scheduling problem in which the first stage contains a single machine, and the second stage contains several identical parallel machines. The objective is to minimise the makespan. For this problem, existing literature emphasises on heur...
We consider the two-stage hybrid flowshop problem with the objective of minimizing the total number of tardy jobs. Since this problem is strongly NP -hard, several heuristic algorithms are developed to find optimal or near optimal schedule for the case when the first stage contains only one mac...
Furthermore, we point out and correct several errors in the paper of Yang [J. Yang, A two-stage hybrid flow shop with dedicated machines at the first stage. Comput. Oper. Res. 40 (2013) 28362843].关键词: Scheduling hybrid flow shop dedicated machines worst case analysis elimination rule ...
We consider the problem of minimizing total completion time in a two-stage hybrid flow shop scheduling problem with dedicated machines at stage 2. There exist one machine at stage 1 and two machines at stage 2. Each job must be processed on the single machine at stage 1 and depending upon...
The two-stage hybrid flow shop scheduling problem with removal and transportation times is addressed in this paper. The maximum completion time is the objective function to be minimized. This scheduling problem is modeling real-life situations encountered in manufacturing and industrial areas. On the ...
