3/2-approximation for Two-machine No-wait Flowshop Scheduling with Availability Constraints
نویسندگان
چکیده
We consider in this paper the two-machine no-wait flowshop problem in which each machine may have an unavailable interval. We present 3 2 -approximation algorithms for the problem when the unavailable interval is imposed on only one machine, or the unavailable intervals on the two machines overlap. These algorithms improve on existing results.

Approximability of two-machine no-wait flowshop scheduling with availability constraints
We consider in this paper the two-machine no-wait flowshop scheduling problem in which each machine may have an unavailable interval. We present a polynomial time approximation scheme for the problem when the unavailable interval is imposed on only one machine, or the unavailable intervals on the two machines overlap.
متن کاملSolving Re-entrant No-wait Flow Shop Scheduling Problem
In this study, we consider the production environment of no-wait reentrant flow shop with the objective of minimizing makespan of the jobs. In a reentrant flow shop, at least one job should visit at least one of the machines more than once. In a no-wait flowshop scheduling problem, when the process of a specific job begins on the first machine, it should constantly be processed without waiting ...
متن کاملSolving Re-entrant No-wait Flexible Flowshop Scheduling Problem; Using the Bottleneck-based Heuristic and Genetic Algorithm
In this paper, we study the re-entrant no-wait flexible flowshop scheduling problem with makespan minimization objective and then consider two parallel machines for each stage. The main characteristic of a re-entrant environment is that at least one job is likely to visit certain stages more than once during the process. The no-wait property describes a situation in which every job has its own ...
متن کاملLot Streaming in No-wait Multi Product Flowshop Considering Sequence Dependent Setup Times and Position Based Learning Factors
This paper considers a no-wait multi product flowshop scheduling problem with sequence dependent setup times. Lot streaming divide the lots of products into portions called sublots in order to reduce the lead times and work-in-process, and increase the machine utilization rates. The objective is to minimize the makespan. To clarify the system, mathematical model of the problem is presented. Sin...
متن کاملَA Multi-objective simulated annealing algorithm to solving flexible no-wait flowshop scheduling problems with transportation times
This paper deals with a bi-objective hybrid no-wait flowshop scheduling problem minimizing the makespan and total weighted tardiness, in which we consider transportation times between stages. Obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational time by using traditional approaches and optimization tools is extremely difficult. This paper presen...
