%A Muthusamy Kanesan %A Hiroaki Ishii %A Shintaro Mohri %A Teruo Masuda %T Beam Search Approach for the Multiobjective Flow-shop Scheduling Problem %X In this paper, we address the problem of minimizing maximum completion time and average flow-time simultaneously in a flow-shop environment. We formulate the problem as a bi-criteria flow-shop scheduling problem in which it minimizes the maximum completion time and average flow-time. We develop and propose an approximation algorithm to find the non-dominated solutions for the above problem. As a solution technique, we propose a new approach based on the beam search with gap concept.
