摘要
We study a two-machine open shop scheduling problem, in which one machine is not available for processing during a given time interval. The objective is to minimize the makespan. We show that the problem is NP-hard and present an approximation algorithm with a worst-case ratio of 4/3. (C) 2001 Elsevier Science B.V. All rights reserved.
