Abstract:

In contrast to the classical scheduling assumption that each job visits each machine once at most, jobs with reentrant style are of a new type of scheduling problems. The basic characteristic of a re-entrant problem is that a job visits certain machines more than once. Re-entrance is usually found in semiconductor manufacturing, and also many other fields. Recently many papers have dealt with the re-entrant scheduling problems. Results and contributions of these references are presented and analyzed in this paper. The contents and methods are classified and introduced according to the machine environments, including single machine, flow shop, flexible flow shop and others. Research directions and trends of re-entrant scheduling problems in the future are presented  at last.

Key words: scheduling, re-entrant, flow shop, makespan, review
