Approximation algorithms for parallel open shop scheduling

Coauthors: Yong Chen, An Zhang

 

Abstract:
This paper investigates a new scheduling problem, namely the parallel open shop scheduling.
In this problem, each job consists of two operations, which must be non-preemptively processed by one of the m two-stage parallel open shops.
The objective is to minimize the makespan. As the problem is NP-hard, we provide the first approximation algorithm with a worst case ratio
of 2 for m machines, and for m=2, an improved algorithm with worst case ration 3/2 is further proposed. Both algorithms run in O(n log n) time.
