In this chapter we consider general flow-shop and job-shop problems for which the number m of machines is variable. All these problems can be proved to be NP-complete from results in previous chapters; consequently the algorithms discussed in this chapter are mainly of the branch-and-bound ...
flow shop scheduling, • job shop scheduling, and • continuous process scheduling. Continuous process scheduling generally applies to 24×7×365 days of continuous processes like oil refining, some process industries like pharmaceuticals, biotechnology, or some specialty chemicals produced in batches,...
An even more specialized flow shop is the proportionate flow shop in which each job has the same processing time on all machines; that is, pij=pj on all machines Mi, i=1,⋯,m; we denote proportionate flow shops using the term “prpt” in the middle field of the problem definition. ...

Introduction Production systems can be divided into three main categories, job shop, flow...
In a proportionate flow shop problem several jobs have to be processed through a fixed sequence of machines and the processing time of each job is equal on
In this paper we consider permutation flow shop scheduling problems with batch setup times. Each job has to be processed on each machine once and the technological routes are identical for all jobs. The set of jobs is divided into groups. There are given processing times t ij of job i on...
作者: G Algorithm 摘要: This literature presents our preliminary work on a genetic algorithm for addressing sequence dependant three stage hybrid flowshop scheduling problems without buffers to minimize the makespan. Even a relatively simple Flexible or Hybrid Flowshop Scheduling收藏...

For job scheduling, Sule (1982) and Proust et al. (1991) have considered the two-machine flow shop scheduling problems with (sequence-independent) setup and removal times separated. Gupta and Darrow, 1985, Gupta and Darrow, 1986 recognize that even the two machine sequence-dependent makespan ...
A flow shop production system made of not identical, failure-prone machines is considered. It is assumed that the time to process a single job, the time to carry out a corrective or preventive maintenance task, and setup times are deterministic. Machines are supposed to fail randomly according...
